ϒ(nS)→Bcρ, BcK⁎ decays with perturbative QCD approach

Inspired by the potential prospects of ϒ(nS) data samples (n=1,2,3) at LHC and SuperKEKB, ϒ(nS)→Bcρ, BcK⁎ decays are studied phenomenologically with pQCD approach. Branching ratios for ϒ(nS)→Bcρ and BcK⁎ decays are estimated to reach up to O(10−11) and O(10−12), respectively. Given the identification and detection efficiency of final states, searching for these weak decay modes should be fairly challenging experimentally in the future.
