# Models of Supersymmetry for Dark Matter

## TL;DR

This paper reviews supersymmetric models and their dark matter candidates, highlighting how extensions beyond the MSSM introduce new possibilities like right-handed sneutrinos and gravitinos, with implications for detection.

## Contribution

It summarizes various supersymmetric models and their dark matter candidates, emphasizing the role of model extensions in solving the $0$ problem and providing new detection prospects.

## Key findings

- Neutralino as WIMP in MSSM with R-parity conservation
- Right-handed sneutrino as dark matter in NMSSM extension
- Gravitino as dark matter in R-parity violating models

## Abstract

A brief review of supersymmetric models and their candidates for dark matter is carried out. The neutralino is a WIMP candidate in the MSSM where $R$-parity is conserved, but this model has the $\mu$ problem. There are natural solutions to this problem that necessarily introduce new structure beyond the MSSM, including new candidates for dark matter. In particular, in an extension of the NMSSM, the right-handed sneutrino can be used for this job. In $R$-parity violating models such as the $\mu\nu$SSM, the gravitino can be the dark matter, and could be detected by its decay products in gamma-ray experiments.
