The ϒ(nS)→BcDs, BcDd decays with perturbative QCD approach

The ϒ(nS)→BcDsϒ(nS)→BcDs, BcDdBcDd weak decays are studied with the pQCD approach firstly. It is found that branching ratios Br(ϒ(nS)→BcDs)∼O(10−10)Br(ϒ(nS)→BcDs)∼O(10−10) and Br(ϒ(nS)→BcDd)∼O(10−11)Br(ϒ(nS)→BcDd)∼O(10−11), which might be measurable in the future experiments.
