• Upsilon
• weak decay
• perturbative QCD approach

The Upsilon (nS) -> B-c* D weak decays (n = 1, 2, 3) are investigated with perturbative QCD approach. It is found that the CKM-favored Upsilon (nS) -> B-c* D-s decays have branching ratio of O (10(-10)), which might be potentially accessible to the future LHC and SuperKEKB experiments.
