Constraints on $R$-parity violating interactions from $\mu \to e\gamma$

Abstract

The lepton number violating process $\mu \to e\gamma$ is used to study the lepton number violating couplings in MSSM extended by terms violating $R$-parity explicitly. Bounds are obtained for the products of $\lambda$- or ${\lambda }^{\prime }$-type couplings. It is found that many of these limits are more stringent than the ones obtained previously.
