Electroproduction 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.

متن کاملLight Vector Mesons
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 suppression of the meson production in heavy ion ...
متن کاملHard Electroproduction of Vector Mesons
In this talk I am going to report on an ongoing analysis [1, 2, 3] of hard electroproduction of light vector mesons within the handbag approach which is based on QCD factorization into hard subprocesses and generalized parton distributions (GPDs) encoding the soft, nonperturbative physics. As is well-known the leading-twist contribution (i.e. employing the collinear approximation) evaluated to ...
متن کاملaxial-vector mesons
A previous model where the low-lying axial-vector mesons are dynamically generated, implementing unitarity in coupled channels in the vector-pseudoscalar (V P ) meson interaction, is applied to evaluate the decay widths of the a1(1260) and b1(1235) axial-vector mesons into πγ. Unlike the case of the a1, the b1 radiative decay is systematically underestimated at tree level. In this work we evalu...
