Electromagnetic Production of Vector Mesons at Low Energies
We have investigated exclusive photoproduction of light vector mesons (ω, ρ and φ) on the nucleon at low energies. In order to explore the questions concerning the socalled missing nucleon resonances, we first establish the predictions from a model based on the Pomeron and meson exchange mechanisms. We have also explored the contributions due to the mechanisms involving sand u-channel intermedi...
متن کاملStrong coupling constants of decuplet baryons with vector mesons
We provide a comprehensive study of strong coupling constants of decuplet baryons with light nonet vector mesons in the framework of light cone QCD sum rules. Using the symmetry arguments, we argue that all coupling constants entering the calculations can be expressed in terms of only one invariant function even if the SUð3Þf symmetry breaking effects are taken into account. We estimate the ord...
متن کاملTensor coupling and vector mesons in dense nuclear matter.
The effects of magnetic interaction between vector mesons and nucleons on the propagation (mass and width) of the ρ-meson in particular moving through very dense nuclear matter is studied and the modifications, qualitative and quantitative, due to the relevant collective modes (zero-sound and plasma frequencies) of the medium discussed. It is shown that the ρ-mesons produced in high-energy nucl...
متن کاملElectroproduction of Vector Mesons
Exclusive electroproduction of vector mesons (VMs) is a particularly good process for studying the transition from the soft to the hard regime of strong interactions [1], the former being well described within the Regge phenomenology while the latter by perturbative QCD (pQCD). The interest in this interplay comes from the need to understand at which scale a partonic language is applicable. The...
متن کاملSkyrmions and vector mesons.
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 partialwave amplitudes are derived for TN ---) pN and TN + wN , and, where possible, are compared with experiment.
