With the potential prospects of the ϒ(1S) data samples at the running LHC and upcoming SuperKEKB, the ϒ(1S)→Bcρ weak decay is studied with the pQCD approach. It is found that (1) the lion's share of branching ratio comes from the longitudinal polarization helicity amplitudes; (2) branching ratio for the ϒ(1S)→Bcρ decay can reach up to O(10−9), which might be hopefully measurable.
