An alternative to the traditional method has been proposed in the form of the loop-tree duality theorem. We present a newly found purely causal r epresentation of the dual integrands and the definitions of several classe s of multiloop topologies as well as their loop-tree duality representatio ns. While the effectiveness of employing the loop-tree duality for obtaini ng asymptotic expansions has been shown previously in the large-mass limit for Higgs production through gluon fusion\, we derive a more general meth od for asymptotic expansion of scattering amplitudes within the loop-tree duality formalism. We apply and analyse this method for the scalar two- an d three-point functions at one-loop order and apply it to highly boosted H iggs boson production.\n\nhttps://indico.ific.uv.es/event/6457/contributio ns/17801/ LOCATION:HUELVA URL:https://indico.ific.uv.es/event/6457/contributions/17801/ END:VEVENT BEGIN:VEVENT SUMMARY:Effective quantum gravity\, cosmological constant and the Standard Model of particle physics DTSTART;VALUE=DATE-TIME:20220322T093000Z DTEND;VALUE=DATE-TIME:20220322T094500Z DTSTAMP;VALUE=DATE-TIME:20260514T191856Z UID:indico-contribution-2487-17815@indico.ific.uv.es DESCRIPTION:Speakers: Ilya Shapiro (Universidade Federal de Juiz de Fora)\ nThe cosmological constant problem (CCP) and the formulation of consistent quantum gravity belong to the shortlist of the most important unsolved fu ndamental problems of physics. In the case of CCP the problem is to explai n the extremely precise (55 orders in the Standard Model) fine-tuning betw een the independent vacuum part and the induced one\, that is a function o f symmetry breaking in the models of particle physics. The situation with CCP is so difficult that it makes sense to give up from attempting its sol ution and accept the need for a fine tuning between the vacuum and induced counterparts of the observed energy density of the vacuum. In this case\, we meet the challenging situation with the renormalization group running of the vacuum or induced summands of the cosmological constant at low ener gies. Assuming the effective approach to quantum gravity and the Vilkovisk y-DeWitt scheme of unique effective action\, one can derive the exact\, we ll-defined\, renormalization group running of the vacuum cosmological cons tant. It turns out that\, owing to the mentioned fine-tuning with the indu ced part\, this running imposes severe restrictions on the possible extens ions of the Minimal Standard Model of particle physics\, concerning the ma gnitude of the vacuum expectation value of the corresponding Higgs fields. \n\nhttps://indico.ific.uv.es/event/6457/contributions/17815/ LOCATION:HUELVA URL:https://indico.ific.uv.es/event/6457/contributions/17815/ END:VEVENT BEGIN:VEVENT SUMMARY:Transverse-momentum structure of the proton DTSTART;VALUE=DATE-TIME:20220322T090000Z DTEND;VALUE=DATE-TIME:20220322T091500Z DTSTAMP;VALUE=DATE-TIME:20260514T191856Z UID:indico-contribution-2487-17814@indico.ific.uv.es DESCRIPTION:Speakers: Gunar Schnell (University of the Basque Country UPV/ EHU)\nAfter fifty years of investigations\, the nucleon structure is still far from being understood and continues to represent a unique test bench for QCD. Despite the enormous progresses achieved in five decades of deep- inelastic scattering (DIS) experiments\, a number of crucial open question s are still on the carpet and subject of intense theoretical and experimen tal studies. In the last two decades\, semi-inclusive DIS was established as a unique tool for the study of the non-collinear structure of nucleons\ , involving the parton transverse momentum pT as an additional degree of f reedom. Requiring the detection of at least one final state-hadron in coin cidence with the scattered lepton\, it opened the way not only to measure of the chiral-odd transversity distribution\, the last missing leading-twi st collinear parton distribution function\, but also to a variety of new p T-dependent PDFs\, known as TMDs. Describing correlations between the quar k transverse momentum and the quark or the nucleon spin (spin-orbit correl ations)\, TMDs account for a number of intriguing effects observed in pola rized and unpolarized reactions\, and allow for a 3-dimensional descriptio n of the nucleon in momentum space. Furthermore\, they could provide insig hts into the yet unmeasured quark orbital angular momentum. At leading-twi st\, eight TMDs enter the SIDIS cross section in conjunction with a fragme ntation function. In addition\, going to the twist-3 level allows us to pr obe novel quark-gluon correlations. The HERMES experiment collected a weal th of data using the 27.6 GeV polarized HERA lepton beam and various polar ized and unpolarized gaseous targets. This allows for a series of unique m easurements of observables sensitive to this multidimensional (spin) struc ture of the nucleon\, probed through specific azimuthal modulations in the distribution of hadrons produced in semi-inclusive DIS. Amplitudes of som e of these modulations sensitive to the beam and/or target polarization\, recently extracted for the first time also in a three-dimensional kinemati c space\, will be presented in more detail.\n\nhttps://indico.ific.uv.es/e vent/6457/contributions/17814/ LOCATION:HUELVA URL:https://indico.ific.uv.es/event/6457/contributions/17814/ END:VEVENT BEGIN:VEVENT SUMMARY:Pion generalized parton distributions: what theory\, lattice QCD a nd experiment can tell us?

Indeed\, new experimental faci lities such as the EIC are planned\, and an unprecedented amount of inform ation about hadron's complexity is expected to arise. This work takes adva ntage of the current situation to perform the first systematic feasibility study of accessing pion's structure at an electron-ion collider. We emplo y state-of-the art models for generalized parton distributions to compute the amplitude for Deeply Virtual Compton Scattering (DVCS) in the one-pion exchange approximation at EIC kinematic. Predictions for the expected eve nt-rates and beam-spin asymmetries are shown. We demonstrate that DVCS off virtual pions will be measurable at the EIC. Moreover\, we evince that gl uons play the dominant role\, modulating the expected number of events thr ough interference with the quark distribution.

This is achieved by means of an ad-hoc Z_2 symmetry\, which forbids the tree-level generation of neutrino masses and stabilizes the lightest Z_2-odd state. Neutrino masses are als o suppressed by a quartic coupling\, usually denoted by λ5. While the sma llness of this parameter is natural\, it is not explained in the context o f the Scotogenic model. We construct an ultraviolet completion of the Scot ogenic model that provides a natural explanation for the smallness of the λ5 parameter and induces the Z2 parity as the low-energy remnant of a glo bal U(1) symmetry at high energies. The low-energy spectrum contains\, bes ides the usual Scotogenic states\, a massive scalar and a massless Goldsto ne boson\, hence leading to novel phenomenological predictions in flavor o bservables\, dark matter physics and colliders.\n\nhttps://indico.ific.uv. es/event/6457/contributions/17805/ LOCATION:HUELVA URL:https://indico.ific.uv.es/event/6457/contributions/17805/ END:VEVENT BEGIN:VEVENT SUMMARY:Semileptonic tau decays beyond the Standard Model DTSTART;VALUE=DATE-TIME:20220321T170000Z DTEND;VALUE=DATE-TIME:20220321T171500Z DTSTAMP;VALUE=DATE-TIME:20260514T191856Z UID:indico-contribution-2487-17804@indico.ific.uv.es DESCRIPTION:Speakers: David Díaz Calderón (IFIC)\nHadronic τ decays are studied as probe of new physics.

We will pay special atte ntion to the infrared limit\, where a logarithmic singularity\, related to the gluon mass generation mechanism and ghost masslessness\, features a z ero-crossing in both the symmetric and asymmetric cases.\n\nhttps://indico .ific.uv.es/event/6457/contributions/17796/ LOCATION:HUELVA URL:https://indico.ific.uv.es/event/6457/contributions/17796/ END:VEVENT BEGIN:VEVENT SUMMARY:Gauge dependence in QCD correlation functions DTSTART;VALUE=DATE-TIME:20220321T140000Z DTEND;VALUE=DATE-TIME:20220321T141500Z DTSTAMP;VALUE=DATE-TIME:20260514T191856Z UID:indico-contribution-2487-17790@indico.ific.uv.es DESCRIPTION:Speakers: Pietro Dall'Olio (Universidad de Huelva)\nCorrelatio n functions are the building blocks in quantum field theory\, from which a ny physical observable can be (in principle) calculated. In a theory with gauge symmetry\, however\, correlation functions are not physical objects\ , being dependent on the particular gauge fixing prescription. In this wor k a novel approach is presented\, which allows to separately calculate\, w ithin the class of linear covariant gauges\, the gauge dependent part of a n arbitrary correlation function. This framework\, which consists in intro ducing a Stueckelberg field and other auxiliary fields in the theory\, all ows to generalize the Landau-Khalatnikov-Fradkin transformations\, known i n quantum electrodynamics\, to the case of non abelian gauge symmetry. Con sistency checks have been carried out by calculating the gauge dependent p arts of the gluon propagator at the one loop level and of the quark propag ator at the two loops level.\n\nhttps://indico.ific.uv.es/event/6457/contr ibutions/17790/ LOCATION:HUELVA URL:https://indico.ific.uv.es/event/6457/contributions/17790/ END:VEVENT END:VCALENDAR
