SKYRMIONS WITH VECTOR-MESONS - STABILITY AND THE VECTOR LIMIT

We discuss the different roles of the omega- and rho-A1-vector mesons for skyrmion stabilization in massive Yang-Mills models using variational arguments and numerical results. Employing the equivalence of massive Yang-Mills models and hidden-gauge models in the non-anomalous sector, we investigate the consequences for possible dynamical realizations of the vector limit of vanishing vector meson masses and couplings in the B = 1 sector of hidden-gauge theories. In hidden-gauge models with axial vector mesons (additional to the vector mesons) the KSFR relation is not modified in the vector limit.
