Electromagnetic Masses of the Massive Yang-Mills Particles K^*(892)

Abstract

Electromagnetic mass difference between neutral $K^{\ast }$ and charged $K^{\ast }$ has been calculated in the $U(3{)}_L\times U(3{)}_R$ chiral fields theory of mesons. It has been revealed that the non-abelian gauge structure of the massive Yang-Mills lagrangian obeyed by $K^{\ast }$ plus VMD (vector meson dominace) causes the EM-mass of neutral one larger than charged one. Experiment supports this effect.
