Radiative transition processes of light vector resonances in a chiral framework

Yun-Hua Chen, Zhi-Hui Guo, Han-Qing Zheng

Within the framework of chiral effective field theory, we study various electromagnetic processes with light vector resonances: $K^{\ast }(892)\to K\gamma$, $e^{+}e^{-}\to K^{\ast}(892)K…
