Anatomy of Higgs mass in Supersymmetric Inverse Seesaw Models

TL;DR

This paper analyzes one-loop corrections to the Higgs mass in supersymmetric inverse seesaw models, revealing conditions under which neutrino sector corrections significantly impact the Higgs mass, and demonstrating compatibility with a 125 GeV Higgs.

Contribution

It provides a detailed calculation of radiative corrections to the Higgs mass in inverse seesaw models, highlighting scenarios with substantial neutrino sector effects and their implications for Higgs mass predictions.

Findings

Neutrino sector corrections can significantly enhance the Higgs mass.

Large left-handed sneutrino soft masses amplify the Higgs mass correction.

The model can naturally accommodate a 125 GeV Higgs with TeV-scale stops.

Abstract

We compute the one loop corrections to the CP even Higgs mass matrix in the supersymmetric inverse seesaw model to single out the different cases where the radiative corrections from the neutrino sector could become important. It is found that there could be a significant enhancement in the Higgs mass even for Dirac neutrino masses of $\mathcal{O}$(30) GeV if the left-handed sneutrino soft mass is comparable or larger than the right-handed neutrino mass. In the case where right-handed neutrino masses are significantly larger than the supersymmety breaking scale, the corrections can utmost account to an upward shift of 3 GeV. For very heavy multi TeV sneutrinos, the corrections replicate the stop corrections at 1-loop. We further show that general gauge mediation with inverse seesaw model naturally accommodates a 125 GeV Higgs with TeV scale stops.
