$B$ meson decays to vector charmonium(like) states and a $K$ meson: the role of final-state interactions

Qi-Wei Yuan, Qi Wu, Ming-Zhu Liu

A series of vector charmonium(like) states, accompanied by a $K$ meson, have been observed in the decays of $B$ meson. These processes are color-suppressed at the quark level, as i…
