Phenomenology of a New Supersymmetric Standard Model: The $\mu\nu$SSM

TL;DR

The paper reviews the phenomenology of the $mbda u$SSM, a supersymmetric model addressing the $mbda$ problem and neutrino masses by incorporating right-handed neutrinos, leading to R-parity breaking.

Contribution

It provides a concise review of the $mbda u$SSM's properties and phenomenology, highlighting its novel approach to solving key issues in supersymmetry.

Findings

Addresses the $mbda$ problem in MSSM

Explains neutrino masses via right-handed neutrinos

Breaks R-parity in the model

Abstract

The $\mu\nu$SSM solves the $\mu$ problem of the MSSM and explains the origin of neutrino masses by simply using right-handed neutrino superfields. The solution implies the breaking of R-parity. The properties and phenomenology of the model are briefly reviewed.
