| Abstract: | Electromagnetic mass difference between neutral K* and charged K* has been calculated in the U(3)L×U(3)R chiral field theory of mesons. It has been revealed that the on-Abelian gauge structure of the massive Yang-Mills Lagrangian obeyed by K* plus VMD (vector meson dominance) causes the EM-mass of neutral one larger than charged one. Experiment supports this anomaly effect. |
