Realizing the supersymmetric inverse seesaw model in the framework of R-parity violation

TL;DR

This paper proposes a supersymmetric inverse seesaw model within R-parity violation that naturally explains neutrino masses and allows the Higgs to reach 125 GeV without heavy stops.

Contribution

It introduces a minimal R-parity violating framework realizing the inverse seesaw with scalar VEVs and shows the Higgs mass can be achieved at 125 GeV at tree level.

Findings

The model successfully generates neutrino masses via the inverse seesaw.

The Higgs mass receives a new tree-level contribution.

The scenario avoids the need for heavy stop particles.

Abstract

If, on one hand, the inverse seesaw is the paradigm of TeV scale seesaw mechanism, on the other it is a challenge to find scenarios capable of realizing it. In this work we propose a scenario, based on the framework of R-parity violation, that realizes minimally the supersymmetric inverse seesaw mechanism. In it the energy scale parameters involved in the mechanism are recognized as the vacuum expectation values of the scalars that compose the singlet superfields $\hat N^C$ and $\hat S$. We develop also the scalar sector of the model and show that the Higgs mass receives a new tree-level contribution that, when combined with the standard contribution plus loop correction, is capable of attaining $125$GeV without resort to heavy stops.
