R-parity violation and quark flavor violation

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-->s gamma and K-0-(K) over bar(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.
