Study on the Υ(1S)→BcM Weak Decays

Abstract

Motivated by the prospects of the potential Υ(1S) particle at high-luminosity heavy-flavor experiments, we studied the Υ(1S)→BcM weak decays, where M = π, ρ, K(∗). The nonfactorizable contributions to hadronic matrix elements are taken into consideration with the QCDF approach. It is found that the CKM-favored Υ(1S)→Bcρ decay has branching ratio of O(10-10), which might be measured promisingly by the future experiments.
