New Limits on R-Parity Breakings in Supersymmetric Standard Models

Abstract

New limits on couplings ${\lambda }_{jk}^i{}^{\prime \prime }$, which break both the baryon number and the $R$--parity, are derived by using a new mechanism that contributes to the neutron-anti-neutron oscillation. The constraints due to proton decay and its potential phenomenology are also reexamined.
