Radiative $W$ and $Z$ Decays and Spontaneous R-Parity Violation
Abstract
Description
We point out that in a class of supersymmetric models where R-parity violation is induced by the spontaneous breaking of local $B-L$ symmetry, the R-parity violating $W$ decay $W\rightarrow\slepγ$ and $Z$ decay $Z\rightarrow\snuγ$, forbidden in the minimal supersymmetric standard model (MSSM), occur at an enhanced rate compared to other models with R-parity breaking. We find that the branching fractions for these modes can be of order $10^{-5}$ .
