Study of $\hat{I}\yen (nS)$ $\to$ $B_{c}P$ decays with perturbative QCD approach

Abstract

With the potential prospects of the $\hat{I}\yen (nS)$ at high-luminosity dedicated heavy-flavor factories, the color-favored $\hat{I}\yen (nS)$ $\to$ $B_c\ddot{I}€$, $B_{c}K$ weak decays are studied with the pQCD approach. It is found that branching ratios for the $\hat{I}\yen (nS)$ $\to$ $B_c\ddot{I}€$ decay are as large as the order of $\mathcal{O}(10^{-11})$, which might be measured promisingly by the future experiments.
