Introduction to chiral symmetry in QCD

H. Sazdjian

The main aspects of chiral symmetry in QCD are presented. The necessity of its spontaneous breakdown is explained. Some low-energy theorems are reviewed. The role of chiral effecti…

SU(5) Unification with TeV-scale Leptoquarks

Peter Cox, Alexander Kusenko, Olcyr Sumensari +1

It was previously noted that SU(5) unification can be achieved via the simple addition of light scalar leptoquarks from two split multiplets. We explore the parameter space…

Accessing Generalized Parton Distributions in Exclusive Photoproduction of a Pair with a Large Invariant Mass

R. Boussarie, B. Pire, L. Szymanowski +1

We propose and study the photoproduction of a pair with a large invariant mass and a small transverse momentum of the final nucleon, as a way to access generalized parton di…

Dark Matter Phenomenology of SM and Enlarged Higgs Sectors Extended with Vector Like Leptons

Andrei Angelescu, Giorgio Arcadi

We will investigate the scenario in which the Standard Model (SM) Higgs sector and its 2-doublet extension (called the Two Higgs Doublet Model or 2HDM) are the "portal" for the int…

Higgs EFT for 2HDM and beyond

Hermès Bélusca-Maïto, Adam Falkowski, Duarte Fontes +2

We discuss the validity of the Standard Model Effective Field Theory (SM EFT) as the low-energy effective theory for the two-Higgs-doublet Model (2HDM). Using the up-to-date Higgs…

Implications of Two-component Dark Matter Induced by Forbidden Channels and Thermal Freeze-out

Mayumi Aoki, Takashi Toma

We consider a model of two-component dark matter based on a hidden symmetry, in which relic densities of the dark matter are determined by forbidden channels and thermal f…

Modelling theoretical uncertainties in phenomenological analyses for particle physics

Jérôme Charles, Sébastien Descotes-Genon, Valentin Niess +1

The determination of the fundamental parameters of the Standard Model (and its extensions) is often limited by the presence of statistical and theoretical uncertainties. We present…

How to employ decays to extract information on scattering

M. Albaladejo, J. T. Daub, C. Hanhart +2

We demonstrate that dispersion theory allows one to deduce crucial information on scattering from the final-state interactions of the light mesons visible in the spectral dist…

Towards an automated tool to evaluate the impact of the nuclear modification of the gluon density on quarkonium, D and B meson production in proton-nucleus collisions

Jean-Philippe Lansberg, Hua-Sheng Shao

We propose a simple and model-independent procedure to account for the impact of the nuclear modification of the gluon density as encoded in nuclear collinear PDF sets on two-to-tw…
