Abstract

We suggest that the ρ meson is a dynamical gauge boson of a hidden local symmetry in the non-linear chiral Lagrangian. The origin of the ρ-meson mass is understood as the Higgs mechanism of the hidden local symmetry. The low-energy dynamics of ρ, π, and matter fields, including the Kawarabayashi-Suzuki-Riazuddin-Fayyazuddin relation and ρ-coupling universality, is consistently described in this new framework. The electromagnetic interaction can be introduced in a unique manner, which gives a successful explanation of ρ dominance of the photon coupling.
