SUSY Dark Matter In Light Of CDMS/XENON Limits

TL;DR

This paper reviews how current CDMS/XENON dark matter detection limits constrain supersymmetric models like MSSM, NMSSM, and nMSSM, and discusses implications for Higgs searches at the LHC.

Contribution

It provides a comprehensive analysis of dark matter constraints on multiple supersymmetric models and their impact on Higgs boson discovery prospects at the LHC.

Findings

CDMS/XENON limits exclude large parts of parameter space in these models.

Future experiments like SuperCDMS and XENON100 will cover most allowed parameter regions.

Charged Higgs bosons are unlikely to be discovered at the LHC under current constraints.

Abstract

In this talk we briefly review the current CDMS/XENON constraints on the neutralino dark matter in three popular supersymmetric models: the minimal (MSSM), the next-to-minimal (NMSSM) and the nearly minimal (nMSSM). The constraints from the dark matter relic density and various collider experiments are also taken into account. The conclusion is that for each model the current CDMS/XENON limits can readily exclude a large part of the parameter space allowed by other constraints and the future SuperCDMS or XENON100 can cover most of the allowed parameter space. The implication for the Higgs search at the LHC is also discussed. It is found that in the currently allowed parameter space the MSSM charged Higgs boson is quite unlikely to be discovered at the LHC while the neutral Higgs bosons $H$ and $A$ may be accessible at the LHC in the parameter space with a large $\mu$ parameter.
