  • Description: <jats:title>A<jats:sc>bstract</jats:sc> </jats:title> <jats:p>We update the bounds on <jats:italic>R</jats:italic>-parity violating supersymmetry originating from meson oscillations in the <jats:italic>B</jats:italic> <jats:sub> <jats:italic>d</jats:italic>/<jats:italic>s</jats:italic> </jats:sub> <jats:sup>0</jats:sup> and <jats:italic>K</jats:italic> <jats:sup>0</jats:sup> systems. To this end, we explicitly calculate all corresponding contributions from <jats:italic>R</jats:italic>-parity violating operators at the one-loop level, thereby completing and correcting existing calculations. We apply our results to the derivation of bounds on <jats:italic>R</jats:italic>-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, <jats:italic>e.g.</jats:italic> from multiple <jats:italic>R</jats:italic>-parity violating couplings or <jats:italic>R</jats:italic>-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.</jats:p>
