Abstract

The branching ratio and direct CPCP asymmetry of the Υ(1S){\Upsilon}(1S) {\to} BcDsB_{c}D_{s} weak decay are estimated with the perturbative QCD approach. It is found that (1) The direct CPCP-violating asymmetry is close to zero. (2) the branching ratio Br(Υ(1S)BcDs){\cal B}r({\Upsilon}(1S){\to}B_{c}D_{s}) {\gtrsim} 101010^{-10} might be measurable at the future experiments.
