The \ensuremathΔS=2 transition b\ensuremath→ssd 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 Bc 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 Bc, up to the 10^\ensuremath-4 range in the minimal supersymmetric model with R-parity violation.
