Multi-Skyrmions with Vector Mesons
It is known that including vector mesons stabilizes the size of a Skyrmion without the need for a Skyrme term. This paper provides the first results for static multiSkyrmions in such a theory. The rational map ansatz is used to investigate multiSkyrmions in a theory which includes the ω vector meson and has no Skyrme term. Bound states with baryon numbers two, three and four are found, which ha...
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 کاملBaby Skyrmions stabilized by vector mesons
Recent results suggest that multi-Skyrmions stabilized by ω mesons have very similar properties to those stabilized by the Skyrme term. In this paper we present the results of a detailed numerical investigation of a (2+1)-dimensional analogue of this situation. Namely, we compute solitons in an O(3) σ-model coupled to a massive vector meson and compare the results to baby Skyrmions, which are s...
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 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 ...
