Abstract
We present a generalized formalism of the hidden local symmetry in which any nonlinear sigma model based on the manifold G/H is gauge equivalent to a model possessing Gglobal ×Glocal symmetry, which is a natural extension of the well-known gauge equivalence between a G/H nonlinear sigma model and a Gglobal ×Hlocal “linear” model. As an application of this formalism, we reexamine a possibility that the A1 mesons as well as the ρ mesons and their U(3) partners are dynamical gauge bosons of the hidden local symmetry, [U(3)L ×U(3)R]local, in the U(3)L ×U(3)R/U(3)V nonlinear sigma model.Keywords
