Electromagnetic self-energies of vector mesons and electromagnetic mass anomaly of the massive Yang-Mills particles

A systematic method developed by the authors to evaluate the one-loop electromagnetic self-energies of the low-lying mesons is extended to the calculation of the vector sector including $rho$, $omega$, and $phi$-mesons. The theoretical result of $rho^0-rho^pm$ electromagnetic mass difference is in agreement with the measurements. An interesting effect called as electromagnetic mass anomaly of the massive Yang-Mills particles is further discussed. There is no new parameter in this study.
