Neutrino mixing in the $\mu\nu$SSM

TL;DR

This paper investigates neutrino masses and mixing angles within the $mbda$ from $ u$ Supersymmetric Standard Model, analyzing how the model explains recent experimental measurements of neutrino oscillations using a top-down approach.

Contribution

It provides a detailed analysis of neutrino masses and mixing in the $mbda$ from $ u$SSM considering both normal and inverted mass orderings, based on a top-down methodology.

Findings

Neutrino masses are generated at tree level via TeV scale seesaw.

The model accommodates recent measurements of the neutrino mixing angle ${ heta_{13}}$.

Analysis covers both normal and inverted mass orderings.

Abstract

Recently, several reactor oscillation experiments have successively measured a nonzero value for the neutrino mixing angle ${\theta_{13}}$, which is greater than 5 standard deviations. Within framework of the $\mu$ from $\nu$ Supersymmetric Standard Model ($\mu\nu$SSM), three tiny neutrino masses are generated at the tree level through TeV scale seesaw mechanism. In this work, we analyze the neutrino masses and mixing in the $\mu\nu$SSM with a "top down" method, assuming neutrino mass spectrum with normal ordering (NO) or inverted ordering (IO).
