By looking at a combination of three decays\, involving the\n125 GeV Higg s boson\, the Z boson and at least one more scalar\, an\nindisputable sign al of CP-violation arises. We use a complex\ntwo-Higgs doublet model as a reference model and present some\nbenchmark points that have passed all c urrent experimental and\ntheoretical constraints\, and that have cross sec tions large enough to\nbe probed at LHC during run 2.\n\nNeutrino mass gen eration through the Higgs mechanism provides a new\ntheoretically consiste nt and experimentally viable paradigm. We\nillustrate this by describing t he main features of the electroweak\nsymmetry breaking sector of the simpl est type-II seesaw model with\nspontaneous breaking of lepton number.\nWe perform an analysis of the sensitivities of Higgs boson searches at\nthe o ngoing ATLAS and CMS experiments at the LHC\, including not only\nthe new contributions to the decay channels present in the Standard\nModel (SM) bu t also genuinely non-SM Higgs boson decays\, such as\ninvisible Higgs boso n decays to majorons. We find sensitivities that\nare likely to be reached soon at LHC\n\nhttps://indico.ific.uv.es/event/2534/contributions/2921/ LOCATION: URL:https://indico.ific.uv.es/event/2534/contributions/2921/ END:VEVENT BEGIN:VEVENT SUMMARY:A brane cosmology with Peccei-Quinn field in SUSY DTSTART;VALUE=DATE-TIME:20160525T153000Z DTEND;VALUE=DATE-TIME:20160525T155000Z DTSTAMP;VALUE=DATE-TIME:20260617T222514Z UID:indico-contribution-2534-2919@indico.ific.uv.es DESCRIPTION:Speakers: Wanil Park (IFIC\, CSIC-Univ Valencia)\nWe propose a scenario of brane cosmology in which Peccei-Quinn field play the role of the inflaton and can solve simultaneously various cosmological/phenomenolo gical issues ( baryogenesis\, dark matter\, axion solution to the strong C P-problem without domain wall problem\, and so on.).\n\nhttps://indico.ifi c.uv.es/event/2534/contributions/2919/ LOCATION: URL:https://indico.ific.uv.es/event/2534/contributions/2919/ END:VEVENT BEGIN:VEVENT SUMMARY:Dark Matter annihilation into sterile neutrinos within a global U( 1)_(B-L) symmetry breaking scenario DTSTART;VALUE=DATE-TIME:20160524T142000Z DTEND;VALUE=DATE-TIME:20160524T144000Z DTSTAMP;VALUE=DATE-TIME:20260617T222514Z UID:indico-contribution-2534-2918@indico.ific.uv.es DESCRIPTION:Speakers: Miguel Escudero (IFIC\, CSIC-Univ Valencia)\nWe inve stigate the possibility that the dark matter is a chiral fermion charged u nder a global $U(1)_{B-L}$ symmetry spontaneously broken\, which only inte racts with sterile neutrinos via a scalar field mediator\, singlet under the Standard Model gauge group. \nWe analyze in detail the phenomenologica l prospects for probing such scenario\, namely\nconstraints from the obser ved dark matter relic density\, direct and indirect dark matter searches a nd new Higgs decay channels.\nWe show that the dark matter annihilation cr oss section into sterile neutrinos can lead to the correct relic abundance by freeze out in a sizable range of the parameter space of the model\, co nsistent with all current observations.\n\nhttps://indico.ific.uv.es/event /2534/contributions/2918/ LOCATION: URL:https://indico.ific.uv.es/event/2534/contributions/2918/ END:VEVENT BEGIN:VEVENT SUMMARY:Limits on Cosmic ALPs Background from cosmic reionization DTSTART;VALUE=DATE-TIME:20160526T130000Z DTEND;VALUE=DATE-TIME:20160526T132000Z DTSTAMP;VALUE=DATE-TIME:20260617T222514Z UID:indico-contribution-2534-2917@indico.ific.uv.es DESCRIPTION:Speakers: Daniele Montanino (Università del Salento &\; IN FN\, Lecce)\nRecently it has been pointed out that a cosmic background of relativistic axion-like particles (ALPs) would be produced by the primordi al decays of heavy fields(moduli) in the post-inflation epoch\, contribut ing to the extra-radiation content in the Universe today. Primordial magne tic fields would trigger conversions of these ALPs into sub-MeV photons du ring the dark ages.

I will discuss first a model where dark matter is m ediated by a leptoquark\, which leads to distinctive signatures at the LHC .

The fully general treatment of coannihilation allows for new exotic mediators to the dark se ctor that should be tackled with non-standard collider search strategies. In this talk\, general classes of LHC signatures describing the full set o f coannihilation models will be introduced.

We explore and compare both a completely general scenario where the heavy neutrinos are integrated out (without any further assumption) and the mor e constrained case with only 3 extra heavy states. The latter assumption i mplies non-trivial correlations that do not allow to saturate all model-in dependent bounds. In addition\, we will analyze the relevance of the 1-⁠ loop corrections when extracting bounds on the mixing in the context of th is model with 3 heavy states.\n\nhttps://indico.ific.uv.es/event/2534/cont ributions/2912/ LOCATION: URL:https://indico.ific.uv.es/event/2534/contributions/2912/ END:VEVENT BEGIN:VEVENT SUMMARY:Composite bound state explanations for the 750 GeV diphoton excess at LHC DTSTART;VALUE=DATE-TIME:20160526T144000Z DTEND;VALUE=DATE-TIME:20160526T150000Z DTSTAMP;VALUE=DATE-TIME:20260617T222514Z UID:indico-contribution-2534-2911@indico.ific.uv.es DESCRIPTION:Speakers: Matthew Talia (University of Sydney)\nWe consider se veral phenomenological explanations for the recent 750 GeV two-photon exce ss reported by ATLAS and CMS. In the first proposal\, we consider an expla nation for the excess from a heavy composite axion\, motivated as a soluti on to the strong CP problem. This can result as a condensate from a higher -colour representation of QCD quarks. Alternatively\, we consider a bound state from two multiply charged\, vector-like isospin singlet leptons as a n explanation for the excess. Such states have been searched for by ATLAS and CMS. In both these proposals we consider photon fusion as the leading production process\, and find that both models can satisfy the excess acc ordingly.\n\nhttps://indico.ific.uv.es/event/2534/contributions/2911/ LOCATION: URL:https://indico.ific.uv.es/event/2534/contributions/2911/ END:VEVENT BEGIN:VEVENT SUMMARY:Pseudo-Goldstone fermions and sterile neutrinos DTSTART;VALUE=DATE-TIME:20160523T161000Z DTEND;VALUE=DATE-TIME:20160523T163000Z DTSTAMP;VALUE=DATE-TIME:20260617T222514Z UID:indico-contribution-2534-2910@indico.ific.uv.es DESCRIPTION:Speakers: Stéphane Lavignac (IPhT)\nWe will discuss the possi bility of sterile neutrinos arising as supersymmetric partners of pseudo-G oldstone bosons of a spontaneously broken global symmetry. We will conside r both the case of an eV-scale sterile neutrino that could be relevant for the experimental anomalies or for future searches for sterile neutrinos\, and the case of a neutrino in the 1 GeV -1 TeV mass range that could be a ccessible at the LHC or at future collider experiments like the ILC or FCC -ee. In the case of an eV-scale sterile neutrino\, we find some correlatio ns between the sterile neutrino mass and the active-sterile mixing angles\ , such that only a part of the parameter space suggested by the Gallium an d reactor anomalies is allowed.\n\nhttps://indico.ific.uv.es/event/2534/co ntributions/2910/ LOCATION: URL:https://indico.ific.uv.es/event/2534/contributions/2910/ END:VEVENT BEGIN:VEVENT SUMMARY:Warm Relaxation of the Weak Scale DTSTART;VALUE=DATE-TIME:20160525T155000Z DTEND;VALUE=DATE-TIME:20160525T161000Z DTSTAMP;VALUE=DATE-TIME:20260617T222514Z UID:indico-contribution-2534-2909@indico.ific.uv.es DESCRIPTION:Speakers: Tevong You (University of Cambridge)\nCosmological r elaxation of the electroweak scale employing the minimal QCD relaxion mech anism is still viable\, provided inflation occurs at finite temperature. T he $\\Theta$-angle problem of the original model is overcome by suppressin g the barrier size during relaxation. After relaxation\, the suppression i s removed and the barrier growth gives rise to the required value of $\\Th eta \\sim \\mathcal{O}(10^{-9})$. In contrast to other solutions of QCD re laxion models\, no axion-inflaton coupling is required. In this case the resolution comes about through a modification of the inflation sector\, in dependently of the relaxion implementation.\n\nhttps://indico.ific.uv.es/e vent/2534/contributions/2909/ LOCATION: URL:https://indico.ific.uv.es/event/2534/contributions/2909/ END:VEVENT BEGIN:VEVENT SUMMARY:Lessons for new physics for Higgs decay to two photons DTSTART;VALUE=DATE-TIME:20160526T103000Z DTEND;VALUE=DATE-TIME:20160526T105000Z DTSTAMP;VALUE=DATE-TIME:20260617T222514Z UID:indico-contribution-2534-2908@indico.ific.uv.es DESCRIPTION:Speakers: Dipankar Das (IFIC\, CSIC-Univ Valencia)\nI will pre sent some examples of two and three Higgs doublet models where the require ment of "alignment" does not necessarily guarantee decoupling. In such sce narios\, a heavy charged scalar in the TeV range can have relatively large contribution to the Higgs to diphoton decay amplitude causing the signal strength to be reduced by more than 10% from the corresponding SM expectat ion. These limiting cases with large quantum effects can be easily ruled o ut by a precision measurement of the diphoton signal strength. I will also comment on a similar situation that arises in a certain limit of the type II seesaw model.\n\nhttps://indico.ific.uv.es/event/2534/contributions/29 08/ LOCATION: URL:https://indico.ific.uv.es/event/2534/contributions/2908/ END:VEVENT BEGIN:VEVENT SUMMARY:Flavour Physics and Yukawa Couplings from E_6 DTSTART;VALUE=DATE-TIME:20160525T132000Z DTEND;VALUE=DATE-TIME:20160525T134000Z DTSTAMP;VALUE=DATE-TIME:20260617T222514Z UID:indico-contribution-2534-2905@indico.ific.uv.es DESCRIPTION:Speakers: Thomas Deppisch (Institue for Theoretical Particle P hysics (KIT))\nSupersymmetric $E_6$ GUT models contain exotic vector-like quark superfields\, which can influence the phenomenology of current and f uture precision experiments in flavour physics.

We consider the prod uction of the right-handed sneutrino by decays of the stau_1\, viz.\, the NLSP in our scenario. We consider constraints on the decay of the stau_1 f rom big-bang nucleosynthesis (BBN) and see that this serves as one of the strongest constraints by restricting its lifetime from a few seconds to a few hundred seconds. In this regard\, we utilize the latest constraints fr om 4-He and D/H. Besides\, we also constrain the mass of the stau_1 from t he search for long-lived particles at the run-I of the LHC.

Here we calculate the leading order QCD corrections to a ll possible d=9 operators contributing to the 0νββ amplitude and use RG E running to calculate 1-loop improved limits. Numerically\, QCD running c hanges limits by factors of the order of or larger than typical uncertaint ies in nuclear matrix element calculations. For some specific cases\, oper ator mixing in the running changes limits even by up to two orders of magn itude. Our results can be straightforwardly combined with new experimental limits or improved nuclear matrix element calculations to re-derive updat ed limits on all short-range contributions to 0νββ decay.\n\nhttps://in dico.ific.uv.es/event/2534/contributions/2891/ LOCATION: URL:https://indico.ific.uv.es/event/2534/contributions/2891/ END:VEVENT BEGIN:VEVENT SUMMARY:Higgs lepton flavor violation and connection to neutrino masses DTSTART;VALUE=DATE-TIME:20160525T140000Z DTEND;VALUE=DATE-TIME:20160525T142000Z DTSTAMP;VALUE=DATE-TIME:20260617T222514Z UID:indico-contribution-2534-2890@indico.ific.uv.es DESCRIPTION:Speakers: Juan Herrero Garcia (KTH\, Stockholm)\nWe study lept on flavor violating Higgs decays in the light of the recent enhancement in the τμ channel\, which should be confirmed/excluded soon at the second run of the LHC.

Since the triplet scalars are pseudo Nambu-Goldstone bosons they are split from the much heavier com posite-sector resonances and are the lightest exotic\, coloured states. Th is makes them ideal to search for at colliders. Due to discrete symmetries the triplet scalar decays via a dimension-six term and given the large su ppression scale f is often metastable. We show that existing searches for collider-stable R-hadrons from Run-I at the LHC forbid a triplet scalar ma ss below 845 GeV\, whereas with 300 inverse femtobarns at 13 TeV triplet s calar masses up to 1.4 TeV can be discovered.

With the aim of obtaining predictions from inflationary models in a concise and straightf orward manner\, I will present the extension of the potential slow-roll ap proximation which incorporates scalar-curvature theories and the derivatio n of new\, generalized potential slow-roll parameters. From this\, I will demonstrate how to extract predictions for cosmological observables for in flationary models with a wide array of theoretical underpinnings.

This is due to a Higgs-background dependent redefinit ion of the Standard Model fields: in terms of canonical variables and in t he large Higgs field limit\, the quantum fluctuations of the redefined fie lds are suppressed by the Higgs background. Thus\, in this regime\, quantu m corrections to the tree-level electroweak potential are negligible. Fina lly\, we show that in this framework the Higgs boson can be responsible fo r inflation.

Clearly the baryon and lepton numbers of the DM particles can be defined only if there exists operators which connect them to the Standard Model (SM) baryons and leptons. As a result the DM pa rticles become intimately linked to the SM particles and can be maximally asymmetric just like the baryons of the SM. We consider an initial asymmet ry that is frozen in either the SM or the DM sectors and the main role of these operators is to make sure that the asymmetry is properly distributed between the SM and DM \nsectors in accordance with observations.

In the general case of a rotatin g\, charged\, cosmological black hole the solution of the KGF equation wit h the method of separation of variables results in Fuchsian ordinary diffe rential equations for the radial and angular parts which contain more than three finite singularities and thereby generalise the Heun differential e quations.

Such a fertile (non-sterile) possibility is certainly important phenomenologically and in this talk I will briefly re view what has been explored so far for fertile right-handed neutrinos. I w ill show that they are not only phenomenologically viable but that their g eneral setup provides very appealing theoretical and model building possib ilities that I believe have been overlooked.\n\nhttps://indico.ific.uv.es/ event/2534/contributions/2844/ LOCATION: URL:https://indico.ific.uv.es/event/2534/contributions/2844/ END:VEVENT BEGIN:VEVENT SUMMARY:Natural SUSY from x-dimensions DTSTART;VALUE=DATE-TIME:20160523T102500Z DTEND;VALUE=DATE-TIME:20160523T105000Z DTSTAMP;VALUE=DATE-TIME:20260617T222514Z UID:indico-contribution-2534-2843@indico.ific.uv.es DESCRIPTION:Speakers: Mariano Quirós (ICREA/IFAE)\nMany problems of the M SSM can be solved in a higher dimensional theory\, using the Scherk-Schwar z mechanism of supersymmetry breaking.

We propose the gra vitino dark matter with bilinear R-parity violating couplings as this sour ce. We compute the electron\, positron and γ -ray fluxes produced by each gravitino decay channel as it would be detected at the Earth’s position . Combining the flux from the different decay modes we are able to reprodu ce AMS-02 measurements of the positron fraction\, as well as the electron and positron fluxes\, with a gravitino dark matter mass in the range 1–3 TeV and lifetime of ∼1.0–0.7×1026 s. The high statistics measurement of electron and positron fluxes\, and the flattening in the behaviour of the positron fraction recently found by AMS-02 allow us to determine th at the preferred gravitino decaying mode by the fit is W ± τ ∓ \, unli ke previous analyses. Then we study the viability of these scenarios throu gh their implication in γ -ray observations. For this we use the Extragal actic γ -ray Background recently reported by the Fermi-LAT Collaboration and a state-of-the- art model of its known contributors. Based on the γ - ray analysis we exclude the gravitino parameter space which provides an ac ceptable explanation of the AMS-02 data.\n\nhttps://indico.ific.uv.es/even t/2534/contributions/2842/ LOCATION: URL:https://indico.ific.uv.es/event/2534/contributions/2842/ END:VEVENT BEGIN:VEVENT SUMMARY:Breaking leptonic symmetries with a Majoron : From lepton flavor v iolation to warm Dark Matter phenomenology DTSTART;VALUE=DATE-TIME:20160523T132000Z DTEND;VALUE=DATE-TIME:20160523T134000Z DTSTAMP;VALUE=DATE-TIME:20260617T222514Z UID:indico-contribution-2534-2841@indico.ific.uv.es DESCRIPTION:Speakers: Lucien Heurtier (U Brussels)\nIn this talk I will pr esent a model in which large lepton flavour violation in the context of a type I seesaw model is generated.

That means considering the 2-loop running of all the couplings with the use of the 1- loop threshold effects that account for the actual (split) spectrum. One o f the largest uncertainties involved at this level of accuracy is due to t he unknown Planck scale effects which introduce shifts in the matching con dition that cause an uncertainty of a several orders of magnitude\nin the predicted scale of gauge coupling unification and hence in the masses of t he heavy fields mediating the proton decay.\n\nWe focused on the minimal r enormalizable non-supersymmetric SO(10) model with the 45 and 126 Higgses\ , where the Planck suppressed gauge kinetic form operators are absent due to the antisymmetry of the adjoint representation. Such scenario could pro vide a realistic breaking pattern and account for the neutrino masses. It has long been known that its tree-level spectrum suffers from tachyonicity \, but by using the effective potential approach we managed to show that a t the quantum level those masses receive substantial corrections and can b ecome non-tachyonic. Establishing that the spectrum of the model is realis tic is only the first step towards providing the first ever NLO computatio n of the corresponding proton lifetime in the future.

We show how this picture precisely applies to their g ravity duals. We investigate the Hamilton-Jacobi equation satisfied by the Wilson action and find the corresponding fixed points and their eigendefo rmations\, which have a diagonal evolution close to the fixed points. The relevant eigendeformations are used to construct renormalised theories. We explore the relation of this formalism with holographic renormalisation. We also discuss different renormalisation schemes and show that the soluti ons to the gravity equations of motion can be used as renormalised couplin gs that parametrise the renormalised theories. This provides a transparent connection between holographic renormalisation group flows in the Wilsoni an and non-Wilsonian approaches. The general results are illustrated by ex plicit calculations in an interacting scalar theory in AdS space.\n\nhttps ://indico.ific.uv.es/event/2534/contributions/2834/ LOCATION: URL:https://indico.ific.uv.es/event/2534/contributions/2834/ END:VEVENT BEGIN:VEVENT SUMMARY:Models for the di-photon excess DTSTART;VALUE=DATE-TIME:20160526T105000Z DTEND;VALUE=DATE-TIME:20160526T111000Z DTSTAMP;VALUE=DATE-TIME:20260617T222514Z UID:indico-contribution-2534-2833@indico.ific.uv.es DESCRIPTION:Speakers: Sebastian Ellis (University of Michigan)\nRecent rep orts by the CMS and ATLAS collaborations of a possible X(750 GeV) state de caying into two photons present the strongest indication yet of new physic s beyond the Standard Model.

In order to answer this question\, we postulate general relations among the quarks and the le ptonic mixing angles at a high scale\, which could be the scale of Grand U nified Theories. The central idea of these relations is that the quark and the leptonic mixing angles can be unified at some high scale either due t o some quark-lepton symmetry or some other underlying mechanism and as a c onsequence\, the mixing angles of the leptonic sector are proportional to that of the quark sector. We investigate the phenomenology of the possible relations where the leptonic mixing angles are proportional to the quark mixing angles at the unification scale by taking into account the latest e xperimental constraints from the neutrino sector. These relations are able to explain the pattern of leptonic mixing at the low scale and thereby hi nt that these relations could be possible signatures of a quark-lepton sym metry or some other underlying quark-lepton mixing unification mechanism a t some high scale linked to Grand Unified Theories.\n\nhttps://indico.ific .uv.es/event/2534/contributions/2819/ LOCATION: URL:https://indico.ific.uv.es/event/2534/contributions/2819/ END:VEVENT BEGIN:VEVENT SUMMARY:Extended gauge groups and neutrinoless double beta decay DTSTART;VALUE=DATE-TIME:20160523T151000Z DTEND;VALUE=DATE-TIME:20160523T153000Z DTSTAMP;VALUE=DATE-TIME:20260617T222514Z UID:indico-contribution-2534-2818@indico.ific.uv.es DESCRIPTION:Speakers: Renato Fonseca (IFIC\, CSIC - Univ Valencia)\nIf neu trinos are Majorana particles\, lepton number is not conserved in Nature a nd double beta decay without the emission of neutrinos should occur.

In the case of t-channel colored mediators\, these sim plified\nmodels often have assumptions on the chirality of the DM-SM inter actions \nwith quarks\, though generically a UV-complete model with such c olored\nmediators would lead to the existence of more free parameters. In this study\nwe look at the effect this broader set of free parameters has on direct detection and the mono-X + MET (X=jet\,W\,Z) signatures at 13 T eV LHC while maintaining gauge invariance of the simplified model under th e full SM gauge group. We find that the direct detection constraints requ ire DM masses less than 10 GeV in order to produce phenomenologically inte resting collider signatures. Additionally\, for a fixed mono-W cross sect ion it is possible to see very large differences in the mono-jet cross sec tion when the usual simplified model assumptions are loosened and isospin violation between RH and LH DM-SM quark couplings are allowed.\n\nhttps:// indico.ific.uv.es/event/2534/contributions/2809/ LOCATION: URL:https://indico.ific.uv.es/event/2534/contributions/2809/ END:VEVENT BEGIN:VEVENT SUMMARY:NLO corrections to Higgs to Higgs decay in the xSM DTSTART;VALUE=DATE-TIME:20160527T095000Z DTEND;VALUE=DATE-TIME:20160527T101000Z DTSTAMP;VALUE=DATE-TIME:20260617T222514Z UID:indico-contribution-2534-2808@indico.ific.uv.es DESCRIPTION:Speakers: Guillaume Chalons (LPSC Grenoble)\nWe study the deca y of a heavy Higgs boson into a light Higgs pair at one loop in the single t extension of the Standard Model.

If the mass difference of the stop to the n eutralino LSP is smaller than the top mass it can only decay flavour viola ting (mainly to charm and neutralino). The decay is not allowed in naive M FV at tree-level and is suppressed by small CKM angels in symmetry based M FV giving a sizable lifetime to the stop.

A general consensus has been expressed on the need for a directional sen sitive detector to confirm\, with a complementary approach\, the candidate s found in “conventional” searches and to finally extend their sensiti vity beyond the limit of neutrino-induced background. We propose here the use of a detector based on nuclear emulsions to measure the direction of W IMP-induced nuclear recoils. The production of nuclear emulsion films with nanometric grains has been recently established. Several measurement camp aigns have demonstrated the capability of detecting sub-micrometric tracks left by low energy ions in such emulsion films with nanometric grains. In novative analysis technologies with fully automated optical microscopes ha ve made it possible to achieve the track reconstruction for path lengths d own to one hundred nanometres and there are good prospects to further exce ed this limit. The detector concept we propose foresees the use of a bulk of nuclear emulsion films surrounded by a shield from environmental radioa ctivity\, to be placed on an equatorial telescope in order to cancel out t he effect of the Earth rotation\, thus keeping the detector at a fixed ori entation toward the expected direction of galactic WIMPs.

A recently developed framework enables us to calculate the Sommerfeld-enhanced relic density in general MSSM scenarios\, properly treating mixed states and mu ltiple co-annihilating channels as well as including off-diagonal contribu tions. Using this framework\, including on-shell one-loop mass splittings and running couplings and taking into account the latest experimental cons traints\, we perform a thorough study of the regions of parameter space su rrounding the well known pure-wino scenario: namely the effect of sfermion masses being non-decoupled and of allowing non-negligible Higgsino or bin o components in the lightest neutralino. We further perform an investigati on into the effect of thermal corrections and show that these can safely b e neglected. The results reveal a number of phenomenologically interesting but so far unexplored regions where the Sommerfeld effect is sizeable. We find\, in particular\, that the relic density can agree with experiment f or dominantly wino neutralino dark matter with masses ranging from 1.7 to beyond 4 TeV. In light of these results the bounds from Indirect Detection on wino-like dark matter are revisited: indirect signals from charged cos mic rays and diffuse gamma rays are also computed within our framework\, a nd we show the impact of the corresponding experimental limits in the new wino-like regions.\n\nhttps://indico.ific.uv.es/event/2534/contributions/2 791/ LOCATION: URL:https://indico.ific.uv.es/event/2534/contributions/2791/ END:VEVENT BEGIN:VEVENT SUMMARY:Di-photon excess and Dirac gauginos DTSTART;VALUE=DATE-TIME:20160526T095000Z DTEND;VALUE=DATE-TIME:20160526T101000Z DTSTAMP;VALUE=DATE-TIME:20260617T222514Z UID:indico-contribution-2534-2790@indico.ific.uv.es DESCRIPTION:Speakers: Luc Darme (LPTHE)\nSupersymmetric models with Dirac masses for the gauginos have both a solid top-down theoretical motivation and a rich phenomenology.

This flat d irection is lifted by small quantum corrections and inflation is realised without need for an unnatural fine-tuning. In the conformal limit\, the ef fective potential becomes linear in the inflaton field\, yielding to speci fic predictions for the spectral index and the tensor-to-scalar ratio\, be ing respectively: n_s−1≈−0.025(N⋆/60)−1 and r≈0.0667(N⋆/60) −1\, where N⋆≈30−65 is a number of e-folds during observable infla tion.

Consequently\, these neu trino lines can be searched for not only with neutrino detectors but also indirectly with gamma-ray telescopes. Here\, we derive limits on the dark matter annihilation cross section into neutrinos based on recent Fermi-LAT and HESS data. We find that\, for dark matter masses above 200 GeV\, gamm a-ray data actually set the most stringent constraints on neutrino lines f rom dark matter annihilation and\, therefore\, the model-independent upper bound on the dark matter total annihilation cross section. In addition\, we point out that gamma-ray telescopes\, unlike neutrino detectors\, have the potential to distinguish the flavor of the final state neutrino. Our r esults indicate that we have already entered into a new era where gamma-ra y telescopes are more sensitive than neutrino detectors to neutrino lines from dark matter annihilation.\n\nhttps://indico.ific.uv.es/event/2534/con tributions/2749/ LOCATION: URL:https://indico.ific.uv.es/event/2534/contributions/2749/ END:VEVENT BEGIN:VEVENT SUMMARY:Is supersymmetry still alive?

This model is of great impor tance since the extra Abelian symmetry groups can originate from different high scale Grand Unified Theories\, like $SO(10)\, E(6)$ etc. \n\nI will briefly discuss three key aspects of the model. First encounters the bound edness of the scalar potential and how vacuum stability constrains the par ameters of this model. Another important aspect is that the model can prov ide a viable dark matter candidate provided the DM stability is ensured by an additional $\\mathbb{Z}_2$ symmetry. Finally I will discuss the intere sting possibility that if the $B-L$ symmetry is broken at very high scale\ , the heavy scalar can act as an inflaton.

In leptonic fl avour models with discrete flavour symmetries\, flavons play a key role to realise these structures. They gain vacuum expectation values which respe ct different residual symmetries in the charged lepton and neutrino sector s and result in special mixing structures after the breaking of the flavou r symmetry. I will introduce a new approach to connect flavour mixing with cross couplings of different flavons. Depending on the coefficients in th e flavon potential\, different vacua preserving different residual symmetr ies can be identified and the tri-bimaximal (TBM) mixing are realised at l eading order. Cross couplings of these flavons result in the breaking of t he residual symmetries and corrections to TBM. These couplings provide new origins for the non-zero reactor angle and CP violation. Models in this a pproach can be achieved by introducing only a few degrees of freedom and c an be more economical than those in the framework of extra dimension or su persymmetry. It also provides a new way\, different from higher dimensiona l operators\, to modify flavour mixing from its leading order results. Sim plicity\, as a great advantage of this approach\, makes it possible for us to establish definite relations between mixing parameters and properties of flavons on one hand\, and test the phenomenological property of flavons on the other hand. One aspect is to test the couplings of flavons and lep tons. These couplings violate lepton flavours\, resulting in both flavour mixing and charged lepton flavour violations. Current experimental constra ints from \\mu to e\\gamma allow the scale of the flavon symmetry not far above the electroweak scale.\n\nhttps://indico.ific.uv.es/event/2534/contr ibutions/2744/ LOCATION: URL:https://indico.ific.uv.es/event/2534/contributions/2744/ END:VEVENT BEGIN:VEVENT SUMMARY:Realistic simplified dark matter models DTSTART;VALUE=DATE-TIME:20160525T134000Z DTEND;VALUE=DATE-TIME:20160525T140000Z DTSTAMP;VALUE=DATE-TIME:20260617T222514Z UID:indico-contribution-2534-2743@indico.ific.uv.es DESCRIPTION:Speakers: Stefan Vogl (Karlsruher Institut für Technologie)\n We show that simplified models used to describe the interactions of dark m atter with Standard Model particles do not in general respect gauge invari ance and that perturbative unitarity may be violated in large regions of t he parameter space. The modifications necessary to cure these inconsistenc ies may imply a much richer phenomenology and lead to stringent constraint s on the model. We illustrate these observations by considering the simpli fied model of a fermionic dark matter particle and a vector mediator. The resulting constraints are typically stronger than the ‘classic’ constr aints on DM simplified models such as monojet searches and make it difficu lt to avoid thermal overproduction of dark matter.\n\nhttps://indico.ific. uv.es/event/2534/contributions/2743/ LOCATION: URL:https://indico.ific.uv.es/event/2534/contributions/2743/ END:VEVENT BEGIN:VEVENT SUMMARY:Neutrino Theory for the Cosmos and the Laboratory DTSTART;VALUE=DATE-TIME:20160526T073000Z DTEND;VALUE=DATE-TIME:20160526T080000Z DTSTAMP;VALUE=DATE-TIME:20260617T222514Z UID:indico-contribution-2534-2742@indico.ific.uv.es DESCRIPTION:Speakers: Ernest Ma (UC Riverside)\nNeutrinos may have interac tions beyond those required by the standard model of quarks and leptons.
