摘要: We study the reaction e+e? ? ??0 in vicinity of mass region. The isospin-violating excitation is accounted for by two major mechanisms. One electromagnetic transition and other strong isospin violations. For latter, we consider contributions from intermediate hadronic meson loops mixing as mechanisms via t- s-channel transitions, respectively. By fitting recent KLOE data, succeed constraining model parameters extracting branching ratio. It shows that ratio sensitive to line shape background contributions. Some crucial insights into correlation between violation Okubo?Zweig?Iizuka rule evading transitions are also learned.
