Neutralino Dark Matter in Gauge Mediation in Light of CDMS-II

TL;DR

This paper proposes a gauge-mediated supersymmetry breaking model where the lightest neutralino acts as dark matter, potentially explaining recent CDMS-II signals indicating dark matter around 100 GeV.

Contribution

It introduces a novel gauge mediation framework that naturally yields a neutralino dark matter candidate consistent with experimental observations.

Findings

Neutralino mass around 100 GeV compatible with CDMS-II signals

Model predicts specific supersymmetric particle spectra

Provides a viable dark matter candidate in gauge mediation context

Abstract

A recent observation of the two candidate events of the dark matter recoiling at CDMS-II is suggestive of dark matter with a mass not far above 100GeV. We propose a model of gauge mediated supersymmetry breaking where the lightest neutralino is identified as dark matter which may provide the observed signals.
