A CoGeNT confirmation of the DAMA signal

Understand

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.
