Neutrino Mass Constraints on R violation and HERA anomaly

Abstract

R parity violating trilinear couplings ${\lambda }_{1jk}^{\prime }$ of the minimal supersymmetric standard model (MSSM) are constrained from the limit on the electron neutrino mass. Strong limits on these couplings follow from the earlier neglected contribution due to sneutrino vacuum expectation values. The limits on most of the ${\lambda }_{1jk}^{\prime }$ couplings derived here are stronger than the existing ones for a wide range in parameters of MSSM. These limits strongly constrain the interpretation of recent HERA results in $e^{+}p$ scattering in terms of production of squarks through $R$ violating couplings. In particular, the interpretation in terms of ${\tilde{t}}_L$ production off strange quark as suggested recently is not viable for wide ranges in MSSM parameters.
