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{r_arrow}s{gamma} and K{sup 0}-{bar K}{sup 0} mixing. In the latter there are two major contributions: one from {open_quotes}direct{close_quotes} one loop diagrams involving RPV couplings, and one from the {open_quotes}indirect{close_quotes} contributions generated by the renormalization group. We compare the effects and discuss the implications of our results. {copyright} {ital 1997} {ital The American Physical Society}
