Chiral Lagrangians and the transition amplitude for radiative muon capture

Abstract

The transition operator for the radiative capture of mesons mu minus by protons is constructed starting from a chiral Lagrangian of the N-pi-rho-a_1-omega system obtained within the approach of hidden local symmetries. The transition operator is gauge invariant and satisfies exactly the CVC and PCAC equations.Comment: 11 pages, 1 figure, LaTex, feynman, submitted to Few-Body System
