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 ...

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 ...

Vector meson condensation in a pion superfluid [PDF]
, 2016 We revisit the suggestion that charged rho-mesons undergo Bose-Einstein condensation in isospin-rich nuclear matter. Using a simple version of the Nambu-Jona-Lasinio (NJL) model, we conclude that rho-meson condensation is either avoided or postponed to ...

Magnetic polarizabilities of light mesons in SU(3) lattice gauge theory
Nuclear Physics B, 2015 We investigate the ground state energies of neutral pseudoscalar and vector meson in SU(3) lattice gauge theory in the strong abelian magnetic field.

Vector meson and heavy meson strong interaction [PDF]
Physical Review D, 2009 We calculate the coupling constants between the light vector mesons and heavy mesons within the framework of the light-cone QCD sum rule in the leading order of heavy quark effective theory. The sum rules are very stable with the variations of the Borel parameter and the continuum threshold.

Holographic model for heavy-vector-meson masses [PDF]
, 2015 The experimentally observed spectra of heavy-vector-meson radial excitations show a dependence on two different energy parameters. One is associated with the quark mass and the other with the binding energy levels of the quark-antiquark pair.

Cornering large-N c QCD with positivity bounds
Journal of High Energy Physics, 2023 The simple analytic structure of meson scattering amplitudes in the large-N c limit, combined with positivity of the spectral density, provides precise predictions on low-energy observables.

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.

Radiative decays of the Y(3940), Z(3930) and the X(4160) as dynamically generated resonances [PDF]
, 2010 We study the radiative decay properties of the charmonium-like X, Y and Z mesons generated dynamically from vector meson-vector meson interaction in the framework of a unitarized hidden-gauge formalism.
