$\theta_{13}$ and the Higgs mass from high scale supersymmetry

TL;DR

This paper explores a high-scale supersymmetry framework that naturally predicts a sizable neutrino mixing angle $ heta_{13}$, minimal CP violation, and a modified Higgs mass through the introduction of SU(2)$_L$ triplet fields.

Contribution

It introduces a novel model that reduces the Higgs mass prediction by incorporating SU(2)$_L$ triplet fields, linking neutrino physics with Higgs mass predictions in high-scale supersymmetry.

Findings

Predicts a large $ heta_{13}$ in neutrino oscillations.

Forecasts a Higgs mass around 141 GeV, reduced by triplet fields.

Suggests negligible CP violation in neutrino oscillations.

Abstract

In the framework in which supersymmetry is used for understanding fermion masses rather than stabilizing the electroweak scale, we elaborate the phenomenological analysis for the neutrino physics. A relatively large $\sin{\theta_{13}}$ is the natural result. The model further predicts vanishingly small CP violation in neutrino oscillations. And $\theta_{23}$ is not necessarily maximal. While the high scale supersymmetry generically results in a Higgs mass of about 141 GeV, our model reduces this mass via introducing SU(2)$_L$ triplet fields which also contribute to neutrino masses.
