Relic neutralinos and the two dark matter candidate events of the CDMS II experiment

TL;DR

This paper proposes that relic neutralinos, previously consistent with DAMA/LIBRA data, could explain the two dark matter candidate events observed by the CDMS II experiment, suggesting a potential dark matter signal.

Contribution

It demonstrates that relic neutralinos can account for CDMS II candidate events, linking results from different dark matter detection experiments.

Findings

Relic neutralinos fit DAMA/LIBRA annual modulation data.

Neutralinos can explain CDMS II candidate events.

Supports the dark matter origin hypothesis for the events.

Abstract

The CDMS Collaboration has presented its results for the final exposure of the CDMS II experiment and reports that two candidate events for dark matter would survive after application of the various discrimination and subtraction procedures inherent in their analysis. We show that a population of relic neutralinos, which was already proved to fit the DAMA/LIBRA data on the annual modulation effect, could naturally explain the two candidate CDMS II events, if these are actually due to a dark matter signal.
