{ital R}-parity violation in flavor-changing neutral current processes and top quark decays

We show that supersymmetric {ital R}-parity-breaking ({ital R/}{sub {ital p}}) interactions always result in flavor changing neutral current processes. Within a single coupling scheme, these processes can be avoided in either the charge +2/3 or the charge {minus}1/3 quark sector, but not both. These processes are used to place constraints on {ital R/}{sub {ital p}} couplings. The constraints on the first and the second generations are better than those existing in the literature. The {ital R/}{sub {ital p}} interactions may result in new top quark decays. Some of these violate electron-muon universality or produce a surplus of {ital b} quark events in {ital t{bar t}} decays. Results from the CDF experiment are used to bound these {ital R/}{sub {ital p}} couplings. {copyright} {ital 1996 The American Physical Society.}
