Axion phenomenology and lattice QCD [PDF]
Proceedings of 34th annual International Symposium on Lattice Field Theory — PoS(LATTICE2016), 2016 The properties of the QCD axion can be studied from the dependence of strong interactions on the θ -parameter. We present a study of the moments of the topological charge for temperatures up to around 600 MeV, obtained by lattice QCD simulations with 2+1

From QCD phenomenology to nuclear physics phenomenology: the chiral confining model
SymmetryInternational audienceWe present a theoretical framework allowing to make an explicit connection between the phenomenology of QCD, namely the properties of the gluon correlator and Wilson loops, and a particular relativistic model for the description of ...

Interplay of nuclear physics, effective field theories, phenomenology, and lattice QCD in neutrino physics [PDF]
, 2022 Experiments in neutrino physics cover a wide range—from deep inelastic scattering, over long base-line oscillation experiments and low-energy coherent neutrino–nucleus scattering (CEνNS), to searches for neutrinoless double β decay (0νββ)—yet in all ...

Phenomenology of the companion-axion model: photon couplings
European Physical Journal C: Particles and Fields, 2022 We study the phenomenology of the ‘companion-axion model’ consisting of two coupled QCD axions. The second axion is required to rescue the Peccei–Quinn solution to the strong-CP problem from the effects of colored gravitational instantons. We investigate

The pion in the graviton soft-wall model: phenomenological applications
European Physical Journal C: Particles and Fields, 2022 The holographic graviton soft-wall model, introduced to describe the spectrum of scalar and tensor glueballs, is improved to incorporate the realization of chiral-symmetry as in QCD.

Tree-level splitting amplitudes for a gluon into four collinear partons
Journal of High Energy Physics, 2020 We compute in conventional dimensional regularisation the tree-level splitting amplitudes for a gluon parent which splits into four collinear partons. This is part of the universal infrared behaviour of the QCD scattering amplitudes at next-to-next-to ...

Large effects from small QCD instantons: making soft bombs at hadron colliders
Journal of High Energy Physics, 2020 It is a common belief that the last missing piece of the Standard Model of particles physics was found with the discovery of the Higgs boson at the Large Hadron Collider.

Analytic results for Sudakov form factors in QCD
Journal of High Energy Physics, 2022 Sudakov form factors appear ubiquitously in factorized cross sections where they allow one to resum large logarithms to all orders in perturbation theory.
