Axion, Neutrinos Masses and $\mu$-Problem in Minimal Supersymmetric Standard Model (MSSM)

TL;DR

This paper reviews a mechanism within the MSSM that generates neutrino masses without breaking R-parity, simultaneously providing a viable axion dark matter candidate and addressing the mu-problem akin to the NMSSM.

Contribution

It introduces a novel approach to generate neutrino masses in MSSM without R-parity violation, linking axion dark matter and the mu-problem solution.

Findings

Neutrino masses are generated without R-parity breaking.

A viable axion dark matter candidate is identified.

The mu-problem is addressed similarly to NMSSM.

Abstract

We review very nice mechanism to generate masses to all the neutrinos in the Minimal Supersymmetric Standard Model (MSSM) without break $R$-parity. In consequence we get viable axion as Dark Matter candidate and at the same time solve the $\mu$-problem in a similar way as done in the Next to Minimal Supersymmetric Model (NMSSM).
