Constraints on $R$-parity violating interactions from $\hat{I}¼\to e{\hat{I}}^3$

Abstract

The lepton number violating process $\hat{I}¼\to e{\hat{I}}^3$ 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 $\hat{I}»$- or $\hat{I}{»}^{\prime }$-type couplings. It is found that many of these limits are more stringent than the ones obtained previously.
