Abstract

We investigate the implications of $R$-parity violation (RPV) for quark flavor violation both by constraining the sneutrino masses to be positive and by studying the processes $b\ensuremath{\rightarrow}s\ensuremath{\gamma}$ and ${K}^{0}$-${\overline{K}}^{0}$ mixing. In the latter there are two major contributions: one from ``direct'' one loop diagrams involving RPV couplings, and one from the ``indirect'' contributions generated by the renormalization group. We compare the effects and discuss the implications of our results.
