Abstract

The Υ(nS){\Upsilon}(nS) {\to} BcDB_{c}^{\ast}D weak decays (nn == 11, 22, 33) are investigated with perturbative QCD approach. It is found that the CKM-favored Υ(nS){\Upsilon}(nS) {\to} BcDsB_{c}^{\ast}D_{s} decays have branching ratio of O(1010){\cal O}(10^{-10}), which might be potentially accessible to the future LHC and SuperKEKB experiments.
