Abstract

The branching ratio and direct $C P$ asymmetry of the $I^¥ (1 S)$ $\to$ $B_{c} D_{s}$ weak decay are estimated with the perturbative QCD approach. It is found that (1) The direct $C P$ -violating asymmetry is close to zero. (2) the branching ratio $B r (I^¥ (1 S) \to B_{c} D_{s})$ $≳$ $1 0^{- 10}$ might be measurable at the future experiments.
