Gauge dependence in QCD correlation functions 15m

Correlation functions are the building blocks in quantum field theory, from which any 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 work a novel approach is presented, which allows to separately calculate, within the class of linear covariant gauges, the gauge dependent part of an arbitrary correlation function. This framework, which consists in introducing a Stueckelberg field and other auxiliary fields in the theory, allows to generalize the Landau-Khalatnikov-Fradkin transformations, known in quantum electrodynamics, to the case of non abelian gauge symmetry. Consistency checks have been carried out by calculating the gauge dependent parts of the gluon propagator at the one loop level and of the quark propagator at the two loops level.

Three-gluon vertex from quenched lattice simulations in general kinematics 15m

We present results for three-gluon vertex form factors in a relatively general kinematics using quenched lattice gauge theory. Three-gluon vertex is the key ingredient of Yang-Mills theory, reflecting its non-Abelian nature and serving as a unique testing ground for any non-perturbative approach such as Dyson-Schwinger techniques. In this work, we have focused on a partially asymmetric kinematic configuration containing both the symmetric (all moments are equal) and the asymmetric (one of the moments is zero) cases studied in the past as particular limits. We will pay special attention to the infrared limit, where a logarithmic singularity, related to the gluon mass generation mechanism and ghost masslessness, features a zero-crossing in both the symmetric and asymmetric cases.

Triple Higgs couplings in the 2HDM and their impact at e+e− colliders 15m

Two Higgs doublet models (2HDM) are one of the simplest and most popular extensions to the SM and predict very different scalar interactions compared to the SM. These new interactions include new triple couplings of the SM-like Higgs bosons with itself and with the new Higgs bosons present in the 2HDM. In consequence, these new triple Higgs interactions can enter at tree-level in the cross section production of two Higgs bosons. In this talk, we analyze the main production channels at e^{+}e^{-} colliders in the 2HDM, namely e^{+}e^{-}\to h_{i}h_{j}\nu\bar{\nu} and e^{+}e^{-}\to h_{i}h_{j}Z with h_{i}h_{j}=hh,\ hH,\ HH\ \text{or}\ AA, and we study the possible effects coming from the triple Higgs couplings. The results of the cross sections are presented in benchmark planes where large triple Higgs couplings can be realized inside the region allowed by all the relevant theoretical and experimental constraints. We also discuss on the relevance of studying the differential cross section on the invariant mass of the two final Higgs bosons to extract the effects of the triple Higgs couplings at future e^{+}e^{-} colliders. We explore the differential cross sections for several benchmark points and sizable effects from \lambda_{hhh}, \lambda_{hhH}, \lambda_{hHH} and \lambda_{hAA} are found, specially at large center-of-mass energies in the h_{i}h_{j}\nu\bar{\nu} production channel.

The Higgs boson: a promising portal to New Physics 15m

The Higgs boson, responsible for the mass of the SM fundamental particles, plays a central role in propounding New Physics (NP) that might shed some light on the still unanswered questions present within the standard frame of particle physics. For example, the appearance of resonances in the scattering of longitudinally polarized vector bosons (intimately related to the Higgs mechanism) would be a clear indication of the presence of such NP. In this presentation I will talk about the importance of the Higgs particle to unravel the questions that we do not get to understand using the standard framework and then focus on the advances in our phenomenological studies on vector boson scattering (VBS) to look for new heavy resonant states.

The new and gauge invariant Littlest Higgs Model with T-parity 15m

In this talk we will first review the Littlest Higgs model with T-parity (LHT), based on the global symmetry group SU(5) broken spontaneously to SO(5), to highlight the pathologies it presents due to the non trivial interplay between the discrete T-parity symmetry and the non-linear realization of the global symmetry. In particular, we will show that the Yukawa Lagrangian responsible for providing mass terms for the heavy fermions is not gauge invariant because their right-handed components transforms in a non-linear representation of SO(5) and such a transformation does not commute, not even restricting to the gauged subgroup, with T-parity. To cure this issue, while preserving most of the structure of the original LHT, we propose to enlarge the global symmetry group with an extra [SU(2)xU(1)]^2 factor broken spontaneously to [SU(2)xU(1)] giving rise to new T-odd scalars. This also allows us to introduce the minimal set of fermionic degrees of freedom required to give masses to all fermions while preserving gauge invariance.

Search of causal Feynman integrals with quantum algorithm 15m

We present a novel benchmark application of a quantum algorithm to Feynman loop integrals. The two on-shell states of a Feynman propagator are identified with the two states of a qubit and a quantum algorithm is used to unfold the causal singular configurations of multiloop Feynman diagrams. To identify such configurations, we exploit Grover's algorithm for querying multiple solutions over unstructured datasets, which presents a quadratic speed-up over classical algorithms when the number of solutions is much smaller than the number of possible configurations. A suitable modification is introduced to deal with topologies in which the number of causal states to be identified is nearly half of the total number of states. The output of the quantum algorithm in IBM Quantum and QUTE Testbed simulators is used to bootstrap the causal representation in the loop-tree duality of representative multiloop topologies. The algorithm may also find application and interest in graph theory to solve problems involving directed acyclic graphs.

Asymptotic expansions and causal representations through the loop-tree duality 15m

Precision calculations needed to disentangle SM predictions from BSM effects involve the calculation of higher-order quantum corrections which pose technical challenges. 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 representation of the dual integrands and the definitions of several classes of multiloop topologies as well as their loop-tree duality representations. While the effectiveness of employing the loop-tree duality for obtaining asymptotic expansions has been shown previously in the large-mass limit for Higgs production through gluon fusion, we derive a more general method for asymptotic expansion of scattering amplitudes within the loop-tree duality formalism. We apply and analyse this method for the scalar two- and three-point functions at one-loop order and apply it to highly boosted Higgs boson production.

Z'-explorer: confronting Z' models against LHC data 15m

Z' boson is a hypothetical mediator that appears in a wide variety of New Physics models, and Z' searches at the LHC have been performed in all SM visible channels, providing limits that must be taken into account non-trivially at the time of constraining each BSM proposal. To ease this task, we present a software, Z'-explorer, to automatically test Z' models against LHC data. By simply providing couplings and decay widths, Z'-explorer allows exploring the parameter space of a given model, determining the most sensitive visible channel for Z' exclusion/detection. We also present a software update, Z'-explorer 2.0, which includes a minimal extension to dark sectors, providing the possibility to explore Z' as an s-channel mediator to fermionic dark matter. This talk is based on 2005.05194 and 2109.13194.

Improved bounds on heavy quark EDMs and implications for BSM 15m

Electric dipole moment (EDM) searches play an crucial role in constraining CP violation sources beyond the Standard Model. We derive new bounds on the EDM of charm and bottom quarks and explore its implications for different New Physics models (1905.02513), with special attention to the so-called Manohar-Wise model, with additional color-octet scalars. For this model, we compute the full set of one-loop diagrams and the enhanced higher-order effects from the Weinberg operator and Barr-Zee diagrams (2111.09397). The constraints on the model parameters from the neutron EDM are studied, finding a powerful complementarity with other flavor obsevables.

Semileptonic tau decays beyond the Standard Model 15m

Hadronic τ decays are studied as probe of new physics. We determine the dependence of several inclusive and exclusive τ observables on the Wilson coefficients of the low-energy effective theory describing charged-current interactions between light quarks and leptons. The analysis includes both strange and non-strange decay channels. The main result is the likelihood function for the Wilson coefficients in the tau sector, based on the up-to-date experimental measurements and state-of-the-art theoretical techniques. The likelihood can be readily combined with inputs from other low-energy precision observables. We discuss a combination with nuclear beta, baryon, pion, and kaon decay data. In particular, we provide a comprehensive and model-independent description of the new physics hints in the combined dataset, which are known under the name of the Cabibbo anomaly.

An ultraviolet completion for the Scotogenic model 15m

The Scotogenic model is an economical scenario that generates neutrino masses at the 1-loop level and includes a dark matter candidate. 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 also suppressed by a quartic coupling, usually denoted by λ5. While the smallness of this parameter is natural, it is not explained in the context of the Scotogenic model. We construct an ultraviolet completion of the Scotogenic 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 global U(1) symmetry at high energies. The low-energy spectrum contains, besides the usual Scotogenic states, a massive scalar and a massless Goldstone boson, hence leading to novel phenomenological predictions in flavor observables, dark matter physics and colliders.

Mapping the SMEFT to discoverable models 15m

The Standard Model Effective Field Theory (SMEFT) has proved a suitable framework to study extensions of the Standard Model in a bottom-up approach. \ In this project we focus on minimal extensions of the SM that will generate certain 4-fermion operators in the SMEFT and use constraints on the Wilson coefficients to derive bounds on the particle masses in said extensions.\ However, only a finite number out of these in theory infinitely many models will be phenomenologically interesting. Allowing only for models that provide an interplay between direct and indirect search and avoid charged Dark Matter leads to a bunch of restrictions that make a classification of these models non-trivial. \ At this stage we use the \textit{ModelGenerator}, a tool built in Mathematica, for a systematic approach to classify these interesting models.

A Green’s basis for the bosonic SMEFT to dimension 8 15m

We present a basis of dimension-eight Green’s functions involving Standard Model (SM) bosonic fields, consisting of 86 new operators. Rather than using algebraic identities and integration by parts, we prove the independence of these interactions in momentum space, including a discussion on evanescent bosonic operators. Our results pave the way for renormalising the SM effective field theory (SMEFT), as well as for performing matching of ultraviolet models onto the SMEFT, to higher order. To demonstrate the potential of our construction, we have implemented our basis in matchmakereft and used it to integrate out a heavy singlet scalar and a heavy quadruplet scalar up to one loop. We provide the corresponding dimension-eight Wilson coefficients. Likewise, we show how our results can be easily used to simplify cumbersome redundant Lagrangians arising, for example, from integrating out heavy fields using the path-integral approach to matching.

Probing Muon g-2 with Sleptons at LHC and Dark Matter Experiments 15m

Inspired by the latest measurement of muon anomalous magnetic moment (muon g-2) by FermiLab we explore the implications about muon g-2 of supersymmetric grand unified theories (GUTs) in a class with non-universal gaugino masses at the GUT scale. The discrepancy between the Standard Model (SM) predictions and the experimental results in muon g-2 can be solved by the contributions from the supersymmetric particles, and the fundamental parameter space compatible with the muon g-2 solution typically favors light sleptons (<~ 800 GeV), charginos (<~ 900 GeV) and LSP neutralino (<~ 600 GeV). In addition to resolve the muon g-2 problem, these mass scales for sleptons, charginos and neutralinos are in reach of LHC currently, and it is expected to have a stronger impact from LHC-Run3. We find that the chargino mass can be probed up to about 600 GeV, and LHC-Run3 is expected to test chargino up to about 700 GeV. Even though there is no direct impact on the slepton masses, these experiments are able to probe the sleptons up to about 350 GeV. However, these scales depend on the handedness of light slepton states, and one can still realize solutions with lighter charginos when the lighter slepton is mostly right-handed. The strongest impact from chargino-neutralino productions is observed when LSP is Bino-like and the chargino is Wino-like, which leads to chargino-neutralino coannihilation scenario, even though the NLSP may happen to be a lighter slepton state. The spectra of SUSY particles involving relatively light chargino, slepton together with LSP neutralino yield also interesting results which can be tested at the current dark matter experiments. In this talk, we present prospects in probing the muon g-2 resolution together with sleptons and charginos at the upcoming LHC experiments and confront it with the current and projected results from the direct dark matter detection experiments.

Using Machine Learning techniques in phenomenological studies in flavour physics 15m

In the recent years, a series of measurements in the observables RK() and RD() concerning the semileptonic decays of the B mesons have shown hints of violations of Lepton Flavour Universality (LFU). An updated model-independent analysis of New Physics violating LFU, by using the Standard Model Effective Field Theory (SMEFT) Lagrangian with semileptonic dimension six operators at Λ = 1 TeV is presented. We perform a global fit, in order to assess the impact of the New Physics in a broad range of observables including B-physics, electroweak precision test, Higgs physics and nuclear β decays. We discuss the relevance of the mixing in the first generation for the observables with heavier lepton flavours. We use for the first time in this context a Montecarlo analysis of the likelihood function to extract the confidence intervals and correlations between observables. Our results show that a suitable strategy is to use a Gradient Boosting predictor as a proxy of the real likelihood function, and to analyze the SHAP values as a measure of the impact of each parameter of SMEFT Lagrangian in the fit.

Probing pion's insight at future colliders: a glue-led structure 15m

Understanding the mechanisms in charge of shaping'' hadrons inside is among the most charming problems in physics. Indeed, new experimental facilities such as the EIC are planned, and an unprecedented amount of information about hadron's complexity is expected to arise. This work takes advantage of the current situation to perform the first systematic feasibility study of accessing pion's structure at an electron-ion collider. We employ 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 event-rates and beam-spin asymmetries are shown. We demonstrate that DVCS off virtual pions will be measurable at the EIC. Moreover, we evince that gluons play the dominant role, modulating the expected number of events through interference with the quark distribution. Finally, a sign-inversion for the observed beam-spin asymmetries is found to take place, triggering a clear signal for a glue-led regime.

Pion generalized parton distributions: what theory, lattice QCD and experiment can tell us? 15m

We discuss how the knowledge of the pion valence-quark distribution function (either obtained from theory, lattice QCD or experiment) can be extended to off-forward kinematics to construct the corresponding generalized parton distribution (GPD). The discussion is based upon the hypothesis of the existence of an energy scale at which the hadron can be completely understood in terms of (fully dressed) valence degrees of freedom, the so called hadronic scale, and an all orders evolution scheme. In addition to being compatible with empirical and lattice results, the obtained GPDs fulfill all the prescriptions from QCD and exhibit agreement with contemporary predictions from continuum Schwinger methods.

Axial-vector meson contributions to the HFS of muonic hydrogen 15m

Extremely precise measurements in muonic hydrogen allow to extract properties from the proton, due to its impact on the energy levels. Such extractions require however from a commensurate precision for other contributions affecting the energy levels, such as two-photon exchange effects. In this talk, we compute the axial-vector meson contribution to the hyperfine splitting of muonic hydrogen, that is relevant to assess the proton Zemach radius, finding significant differences with respect to previous estimates.

Transverse-momentum structure of the proton 15m

After 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 questions are still on the carpet and subject of intense theoretical and experimental 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 freedom. Requiring the detection of at least one final state-hadron in coincidence with the scattered lepton, it opened the way not only to measure of the chiral-odd transversity distribution, the last missing leading-twist collinear parton distribution function, but also to a variety of new pT-dependent PDFs, known as TMDs. Describing correlations between the quark transverse momentum and the quark or the nucleon spin (spin-orbit correlations), TMDs account for a number of intriguing effects observed in polarized and unpolarized reactions, and allow for a 3-dimensional description of the nucleon in momentum space. Furthermore, they could provide insights into the yet unmeasured quark orbital angular momentum. At leading-twist, eight TMDs enter the SIDIS cross section in conjunction with a fragmentation function. In addition, going to the twist-3 level allows us to probe novel quark-gluon correlations. The HERMES experiment collected a wealth of data using the 27.6 GeV polarized HERA lepton beam and various polarized and unpolarized gaseous targets. This allows for a series of unique measurements of observables sensitive to this multidimensional (spin) structure of the nucleon, probed through specific azimuthal modulations in the distribution of hadrons produced in semi-inclusive DIS. Amplitudes of some of these modulations sensitive to the beam and/or target polarization, recently extracted for the first time also in a three-dimensional kinematic space, will be presented in more detail.

Effective quantum gravity, cosmological constant and the Standard Model of particle physics 15m

The cosmological constant problem (CCP) and the formulation of consistent quantum gravity belong to the shortlist of the most important unsolved fundamental problems of physics. In the case of CCP the problem is to explain the extremely precise (55 orders in the Standard Model) fine-tuning between the independent vacuum part and the induced one, that is a function of 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 solution 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 energies. Assuming the effective approach to quantum gravity and the Vilkovisky-DeWitt scheme of unique effective action, one can derive the exact, well-defined, renormalization group running of the vacuum cosmological constant. It turns out that, owing to the mentioned fine-tuning with the induced part, this running imposes severe restrictions on the possible extensions of the Minimal Standard Model of particle physics, concerning the magnitude of the vacuum expectation value of the corresponding Higgs fields.
