Abstract: (Elsevier)
It is shown that a skyrion can be stabilized by introducing ϱ-mesons into the chiral SU(2) L × SU(2) R lagrangian without higher-derivative terms like the Skyrme term. The ϱ-mesons are considered as dynamical gauge bosons associated with a hidden local symmetry of the non-linear sigma model. The lagrangian reduces to the Skyrme model in a limit of parameters. The Skyrmion mass M is found to be M = 1058 MeV when the parameters are fixed so as to satisfy the KSRF relation. It is also shown that a solition solution in a model with Ω-meson coupled with the baryonic current is a saddle-point solution.
