Light-cone distribution amplitudes of vector meson in a large momentum effective theory [PDF]
Physical Review D, 2018 We investigate the leading twist light-cone distribution amplitudes (LCDAs) of vector meson in the framework of large momentum effective theory. We derive the matching equation for the LCDAs and quasidistribution amplitudes. The matching coefficients are

Diffractive incoherent vector meson production off protons: a quark model approach to gluon fluctuation effects [PDF]
The European Physical Journal C, 2018 Fluctuations play an important role in diffractive production of vector mesons. It was in particular recently suggested, based on the Impact-Parameter dependent Saturation model (IPSat), that geometrical fluctuations triggered by the motion of the ...

Constituent quark axial current couplings to light vector mesons in the vacuum and with a weak magnetic field [PDF]
, 2021 Unusual constituent quark axial current couplings to light vector mesons, $\rho$ and $\omega$, are derived in the vacuum and under weak magnetic field by considering a quark-antiquark interaction mediated by a non perturbative gluon exchange. Similarly, light axial mesons are found to couple anomalously with the constituent quark vector current.

On the chiral expansion of vector meson masses [PDF]
Physical Review D, 2018 We study the chiral expansion of meson masses and decay constants using a chiral Lagrangian that was constructed previously based on the hadrogenesis conjecture. The one-loop self energies of the Goldstone bosons and vector mesons are evaluated.

QCD phase diagram with a background magnetic field in an improved soft-wall AdS/QCD model
European Physical Journal C: Particles and Fields, 2021 We studied the magnetic effects on the chiral transition and the melting properties of vector and axial-vector mesons in the improved soft-wall AdS/QCD model under a charged magnetic background, which is solved perturbatively from an Einstein–Maxwell ...

Holographic picture of heavy vector meson melting [PDF]
The European Physical Journal C, 2016 The fraction of heavy vector mesons produced in a heavy ion collision, as compared to a proton–proton collision, serves as an important indication of the formation of a thermal medium, the quark–gluon plasma.

The European Physical Journal C, 2009 This article reviews the current status of experimental results obtained in the measurement of light vector mesons produced in proton-proton and heavy ion collisions at different energies. The review is focused on two phenomena related to the light vector mesons; the modification of the spectral shape in search of Chiral symmetry restoration and ...
