Study on the $\hat{I}\yen (1S)$ $\to$ $B_{c}M$ weak decays

Abstract

Motivated by the prospects of the potential $\hat{I}\yen (1S)$ particle at high-luminosity heavy-flavor experiments, we studied the $\hat{I}\yen (1S)$ $\to$ $B_{c}M$ weak decays, where $M$ $=$ $\ddot{I}€$, $\ddot{I}$, $K^{(\ast )}$. The nonfactorizable contributions to hadronic matrix elements are taken into consideration with the QCDF approach. It is found that the CKM-favored $\hat{I}\yen (1S)$ $\to$ $B_c\ddot{I}$ decay has branching ratio of $\mathcal{O}(10^{-10})$, which might be measured promisingly by the future experiments.
