# Supersymmetric Dark Matter in Light of WMAP

## TL;DR

This paper refines the parameter space of the CMSSM considering WMAP data, significantly constraining the LSP mass and enhancing prospects for supersymmetry detection at colliders.

## Contribution

It provides updated bounds on the supersymmetric particle masses based on cosmological data, improving the testability of supersymmetry at current and future colliders.

## Key findings

- LSP mass limit is below 500 GeV for certain parameters.
- Reduced parameter space enhances LHC detection prospects.
- Increased likelihood of measuring supersymmetric particles at a 1-TeV linear collider.

## Abstract

We re-examine the parameter space of the constrained minimal supersymmetric extension of the Standard Model (CMSSM), taking account of the restricted range of \Omega_{CDM} h^2 consistent with the WMAP data. This provides a significantly reduced upper limit on the mass of the lightest supersymmetric particle LSP: m_\chi < 500 GeV for \tan \beta < 45 and \mu > 0, or \tan \beta < 30 and \mu < 0, thereby improving the prospects for measuring supersymmetry at the LHC, and increasing the likelihood that a 1-TeV linear e^+ e^- collider would be able to measure the properties of some supersymmetric particles.
