A CoGeNT confirmation of the DAMA signal

TL;DR

This paper demonstrates that mirror dark matter can simultaneously explain the DAMA annual modulation and CoGeNT's rising low energy spectrum, providing a model-dependent confirmation of DAMA's signal.

Contribution

It shows that mirror dark matter models can account for both DAMA and CoGeNT observations, strengthening the case for this dark matter paradigm.

Findings

Mirror dark matter explains both signals consistently.

Supports the mirror dark matter paradigm.

Provides a model-dependent confirmation of DAMA.

Abstract

The CoGeNT collaboration has recently reported a rising low energy spectrum in their ultra low noise germanium detector. This is particularly interesting as the energy range probed by CoGeNT overlaps with the energy region in which DAMA has observed their annual modulation signal. We show that the mirror dark matter candidate can simultaneously explain both the DAMA annual modulation signal and the rising low energy spectrum observed by CoGeNT. This constitutes a model dependent confirmation of the DAMA signal and adds weight to the mirror dark matter paradigm.
