Charm meson scattering cross sections by pion and rho meson [PDF]

, 2001
Using the local flavor SU(4) gauge invariance in the limit of vanishing vector meson masses, we extend our previous study of charm meson scattering cross sections by pion and rho meson, which is based only on the pseudoscalar-pseudoscalar-vector meson ...

Vector mesons polarization versus color transparency

EPJ Web of Conferences, 2017
Vector mesons V = ρ, ω, φ can be transversely (helicity λ = ±1) or longitudinally (λ = 0) polarized. Can vector mesons polarization influence on their interaction with nucleons and nuclei?

Exploration of trace anomaly contribution to proton mass based on light vector meson photoproduction

European Physical Journal C: Particles and Fields, 2023
In the quantum chromodynamics, the mass source of the proton is decomposed into four parts by the energy momentum tensor: quark energy term, gluon energy term, quark mass term and trace anomaly term.

Radiative decays of vector and pseudoscalar nonets

EPJ Web of Conferences, 2012
Using a counting scheme which treats the light pseudoscalar and the light vector-meson nonet on equal footing, the decays of the narrow light vector mesons into a pseudoscalar meson and a dilepton and of the η′ meson into an ɷ meson and a dielectron are ...

Complete calculation of exclusive heavy vector meson production at next-to-leading order in the dipole picture

Journal of High Energy Physics, 2022
Exclusive production of transversely polarized heavy vector mesons in deep inelastic scattering at high energy is calculated at next-to-leading order accuracy in the Color Glass Condensate framework.

The reggeometric pomeron and exclusive production of J/ψ and ψ(2S) in ultraperipheral collisions at the LHC

Physics Letters B, 2022
By using a Regge-pole model for vector meson production (VMP), successfully describing the HERA data, we analyse the correlation between VMP cross sections in photon-induced reactions at HERA and those in ultra-peripheral collisions at the Large Hadron ...

Melting Spectral Functions of the Scalar and Vector Mesons in a Holographic QCD Model [PDF]

, 2009
We investigate the finite-temperature spectral functions of heavy quarkonia by using the soft-wall AdS/QCD model. We discuss the scalar, the pseudo-scalar, the vector, and the axial-vector mesons and compare their qualitative features of the melting ...

Vector-meson dominance revisited

EPJ Web of Conferences, 2012
The interaction of mesons with electromagnetism is often well described by the concept of vector-meson dominance (VMD). However, there are also examples where VMD fails.

Exclusive vector mesons at high energies: from photon-proton to proton-proton and nucleus-nucleus collisions

EPJ Web of Conferences, 2012
Photoproduction of vector mesons has been studied since the 1960’s and was instrumental in establishing the hadronic structure of the photon and the concept of vectormeson dominance.
