The two-body hadronic decays of B c meson in the perturbative QCD approach: a short review

Abstract

Along with the running of Large Hadron Collider (LHC) located at CERN in November 2009, a large number of data samples of $$B_c$$ meson have been collected and some hadronic $$B_c$$ decay modes have been measured by the LHC experiments. In view of the special and important roles of $$B_c$$ meson decays playing in the heavy flavor sector, we here give a short review on the status of two body hadronic decays $$B_c \rightarrow M_1 M_2$$ at both experimental and theoretical aspects. For the theoretical progresses, specifically, we will show lots of theoretical studies on two body hadronic $$B_c$$ decays involving pseudoscalar, vector, scalar, axial-vector, even tensor meson(s) in the final states by employing the perturbative QCD (pQCD) factorization approach. We will present a general analysis about the two-body hadronic decays of the heavy $$B_c$$ meson and also provide some expectations for the future developments.
