ABSTRACT We argue that the Bc exclusive nonleptonic decays are perturbatively calculable. Working in a perturbative QCD model of Brodsky et al., we pay attention to the estimate of the partial widths of the modes , , etc., which serve to identify Bc mesons and determine the Bc mass and life time. Our estimations are found to be lower than the other predictions. We note that the spectator ansatz might be misleading in dealing with Bc weak decays. So the results will be potentially important at LHC to measure the Bc meson and to test various models of weak decays of heavy mesons.

ABSTRACT: We study the exclusive nonleptonic B_{c}→VV decays, within the factorization approximation, in the framework of the relativistic independent quark model, based on a confining potential in the scalarvector harmonic form. The weak form factors are extracted from the overlap integral of meson wave functions derived in the relativistic independent quark model. The predicted branching ratios for different B_{c}meson decays are obtained in a wide range, from a tiny value of O(10^{6}) for B_{c}→D^{*}D_{(s)}^{*} to a large value of 24.32% for B_{c}→B_{s}^{*}ρ^{}, in general agreement with other dynamicalquarkmodel predictions. The decay modes B_{c}→B_{s}^{*}ρ^{} and B_{c}→B^{*}ρ^{} with high branching ratios of 24.32% and 1.73%, respectively, obtained in this model should be detectable at the LHC and Tevatron in the near future. The b→c, u induced decays are predicted predominantly in the longitudinal mode, whereas the c[over ¯]→s[over ¯], d[over ¯] induced decays are obtained in a slightly higher transverse mode. The CPodd fractions (R_{⊥}) for different decay modes are predicted and those for colorfavored B_{c}→D^{*}D^{*}, D^{*}D_{s}^{*} decays indicate significant CP violation in this sector.Physical Review D 11/2013; 88(9).

ABSTRACT: Using the leadingorder lowenergy effective Hamiltonian, we calculate [iopmath latex="$B_c\rightarrow PP$"] BcPP [/iopmath] (where P stands for pseudoscalar meson) decays induced by pure Wemission mechanisms. In order to estimate the hadronic matrix elements, we apply the perturbative quantum chromodynamics (PQCD) method proposed by Szczepaniak et al. [Phys. Lett. B 243 (1990) 287] and developed by Simma et al. [Phys. Lett. B 272 (1991) 395]. Compared with the predictions of other models, we find that the PQCD method is suitable for these decays and therefore the spectator ansatz seems questionable.Chinese Physics Letters 01/2001; 18(4).

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, axialvector, even tensor meson(s) in the final states by employing the perturbative QCD (pQCD) factorization approach. We will present a general analysis about the twobody hadronic decays of the heavy \(B_c\) meson and also provide some expectations for the future developments.Chinese Science Bulletin 10/2014; 59(2930).
