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→s\ensuremathγ and K⁰-K⁰ 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.
