Vector-meson dominance and diffractive electroproduction of vector mesons
Nuclear Physics B, 1969 Abstract A vector-meson dominance model of diffractive electroproduction of vector mesons at high energies is presented. The assumption that the invariant amplitudes are slowly varying as a function of the vector-meson mass, when extrapolating to the spacelike region, is shown to lead to serious difficulties when combined with helicity independence ...

Skyrmions and Vector Mesons [PDF]
Physical Review Letters, 1986 We discuss the scattering of mesons of arbitrary spin and isospin from baryons in models in which the baryon is considered a soliton, or ''skyrmion,'' in an effective Lagrangian of mesons. Model-independent linear relations between partial-wave amplitudes are derived for piN..-->..rhoN and ..pi..N..--> omega..N, and, where possible, are compared with ...

Vector meson–vector meson interaction and dynamically generated resonances
Journal of Physics: Conference Series, 2012 We report upon 11 composite meson states, dynamically generated from the vector meson–vector meson interaction using the local hidden gauge formalism within a unitary approach. Six of these states are associated to the f0(1370), f0(1710), f2(1270), f'2(1525), a2(1320) and K*2(1430) resonances.

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.

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.

EPJ Web of Conferences, 2014 We discuss the CMS capabilities of measuring vector mesons in pp and heavyion collisions based on the recent results of the exclusive dilepton and diboson production. Studies evaluating the detection of exclusive J/ψ and ϒ vector meson photoproduction in

Physics Letters B, 2018 We make predictions for cross sections of ρ and ϕ vector meson photoproduction in ultraperipheral Xe–Xe collisions at sNN=5.44TeV. Analyzing the momentum transfer distribution of ρ mesons in this process, we explore the feasibility of extracting the ...
