Neutrino masses and mixings in the baryon triality constrained minimal supersymmetric standard model

TL;DR

This paper demonstrates how the baryon triality constrained supersymmetric Standard Model can accommodate experimental neutrino oscillation data, including hierarchical, inverted, and degenerate mass scenarios, with implications for LHC phenomenology.

Contribution

It introduces a new version of SOFTSUSY with full one-loop neutrino mass calculations within the baryon triality cSSM framework, aligning with recent cosmological observations.

Findings

Viable neutrino mass and mixing solutions compatible with WMAP data.

Implementation of full one-loop neutrino masses in SOFTSUSY.

Discussion of potential LHC phenomenological signatures.

Abstract

We discuss how the experimental neutrino oscillation data can be realized in the framework of the baryon triality ($B_3$) constrained supersymmetric Standard Model (cSSM). We show how to obtain phenomenologically viable solutions, which are compatible with the recent WMAP observations. We present results for the hierarchical, inverted and degenerate cases which illustrate the possible size and structure of the lepton number violating couplings. We work with a new, as yet unpublished version of SOFTSUSY, where we implemented full one--loop neutrino masses. Finally, we shortly discuss some phenomenological implications at the LHC.
