Quark flavor phenomenology of the QCD axion [PDF]
, 2020 Axion models with generation-dependent Peccei-Quinn charges can lead to flavor-changing neutral currents, thus motivating QCD axion searches at precision flavor experiments.

Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 We investigate the exclusive semileptonic and rare D⟶π(K) decays within the standard model together with the light‐front quark model (LFQM) constrained by the variational principle for the QCD‐motivated effective Hamiltonian. The form factors are obtained in the q+ = 0 frame and then analytically continue to the physical timelike region.

Ising-QCD phenomenology close to the critical point [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2018 We employ the recently introduced Ising-QCD partition function (N.~G. Antoniou {\it et al.}, Phys. Rev. D 97, 034015 (2018)) to explore in detail the behaviour of the moments of the baryon-number, within the critical region around the critical endpoint ...

Gravitational transition form factors of N → ∆ via QCD light-cone sum rules
Journal of High Energy Physics, 2023 We present the first direct calculation on the gravitational form factors (GFFs) of the N → ∆ transition using an analytic method, the QCD light-cone sum rules. The matrix element of the quark part of the energy momentum tensor current sandwiched between

A possible subthreshold pole in S 11 channel from πN Roy-Steiner equation analyses
Journal of High Energy Physics, 2022 The hyperbolic version of Roy-Steiner equation describing low energy πN scatterings, with larger analyticity domain in the complex s plane is solved. The numerical results on phase shifts of low partial waves are in agreement with that of Hoferichter et ...

Quantum kinetic theory for spin transport of quarks with background chromo-electromagnetic fields
Journal of High Energy Physics, 2022 We derive the quantum kinetic equations for massive and massless quarks coupled with the background chromo-electromagnetic fields from the Wigner-function approach with the n expansion and effective power-counting scheme.

Anisotropic flow and the valence quark skeleton of hadrons
Journal of High Energy Physics, 2023 We study transverse momentum anisotropies, in particular, the elliptic flow v 2 due to the interference effect sourced by valence quarks in high-energy hadron-hadron collisions. Our main formula is derived as the high-energy (eikonal) limit of the impact-

Hadronic vacuum polarization and the MUonE proposal
Journal of High Energy Physics, 2022 The MUonE proposal at the CERN SPS consists in extracting the value of the hadronic vacuum polarization self-energy function (HVP) from its contribution to the differential cross-section of elastic muon-electron scattering.
