$S$-wave contributions to the $B_{(s)}\to {\chi }_{c1}(\pi \pi ,K\pi ,KK)$ decays

Meng-Kun Jia, Chao-Qi Zhang, Jia-Ming Li +1

We make a detailed study of the three-body decays $B_{(s)}\to {\chi }_{c1}h{h}^{\prime }$, where $h^{{(}^{\prime })}$ is either a pion or kaon, by taking into account the $S$-wave states in the $h{h}^{\prime }$…
