Study of ϒ(nS)→BcP decays with perturbative QCD approach

With the potential prospects of the ϒ(nS)ϒ(nS) at high-luminosity dedicated heavy-flavor factories, the color-favored ϒ(nS)→Bcπϒ(nS)→Bcπ, BcKBcK weak decays are studied with the pQCD approach. It is found that branching ratios for the ϒ(nS)→Bcπϒ(nS)→Bcπ decay are as large as the order of O(10−11)O(10−11), which might be measured promisingly by the future experiments.
