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.
