| dc.description | The $ΔS = 2$ transition $b \to s s \bar d$ is extremely small in the standard model, proceeding only via box diagrams. Such decays are thus an appropriate ground for searching new physics. We present a study of several two-body and three-body decays of the B_c meson belonging to this class. Our calculation covers the minimal supersymmetric model with and without R-parity and a two-Higgs-doublet model. The current limits on the parameters of these models allow for rather large branching ratios for several two and three-body hadronic decay modes of B_c, up to the 10^{-4} range in the minimal supersymmetric model with R-parity violation. | |
