Combining Supersymmetric Dark Matter with Recent Accelerator Data

TL;DR

This paper examines how recent experimental data from the Brookhaven muon g-2 experiment and LEP Higgs bounds constrain supersymmetric dark matter models within the CMSSM framework, affecting cosmology and direct detection prospects.

Contribution

It provides an analysis of the combined impact of recent accelerator results on the parameter space of supersymmetric dark matter models, integrating collider and cosmological constraints.

Findings

Certain parameter regions are excluded by the new g-2 and Higgs bounds.

Remaining viable regions suggest specific dark matter detection prospects.

The results refine the understanding of supersymmetric dark matter compatibility with current data.

Abstract

In the framework of the Constrained Minimal Supersymmetric Standard Model we discuss the impact of the recent experimental information, especially from the E821 Brookhaven experiment on $g_{\mu}-2$ along with the light Higgs boson mass bound from LEP, in delineating regions of the parameters which are consistent with cosmological data. The effect of these to the Dark Matter direct searches is also discussed.
