Updating bounds on R-parity violating supersymmetry from meson oscillation data
Abstract
We update the bounds on R-parity violating supersymmetry originating from meson oscillations in the B d/ s 0 and K 0 systems. To this end, we explicitly calculate all corresponding contributions from R-parity violating operators at the one-loop level, thereby completing and correcting existing calculations. We apply our results to the derivation of bounds on R-parity violating couplings, based on up-to-date experimental measurements. In addition, we consider the possibility of cancellations among flavor-changing contributions of various origins, e.g. from multiple R-parity violating couplings or R-parity conserving soft terms. Destructive interferences among new-physics contributions could then open phenomenologically allowed regions, for values of the parameters that are naively excluded when the parameters are varied individually.
