Parameter scan with neutrino mass in the Singlet-Triplet extension of the Minimal Supersymmetric Standard Model

Abstract

The Minimal Supersymmetric Standard Model (MSSM) provides a possible origin of the smallness of the neutrino mass through different mechanisms such as by introducing right-handed sneutrinos or through some cancellation mechanism. One cancellation mechanism in particular has been studied in the past for extensions to the MSSM such as the Singlet-extended and Triplet-extended MSSM with R-parity violation (RpV). We consider the combined singlet and triplet-extended MSSM with RpV and perform a numerical scan of the parameter space model motivated by the neutrino mass calculation. Applying experimental and theoretical constraints, we show that the dependence of the heaviest neutrino mass eigenstate to the free parameters of the model are consistent with tree-level calculations.
