Singlet Fermionic Dark Matter explains DAMA signal

TL;DR

This paper proposes that Singlet Fermionic Dark Matter can explain the DAMA annual modulation signal while matching the observed relic density, offering a viable candidate within current experimental constraints.

Contribution

It introduces Singlet Fermionic Dark Matter as a new candidate capable of explaining DAMA results and achieving correct relic density.

Findings

Singlet Fermionic Dark Matter can reconcile DAMA signal with null experiments.

The candidate achieves the correct thermal relic density consistent with WMAP.

It is compatible with elastic scattering explanations involving channeling effects.

Abstract

It has been suggested that, considering channeling effect, the order of a few GeV dark matters which are elastically scattered from detector nuclei might be plausible candidates reconciling the DAMA annual modulation signal with the results of other null experiments. We show that Singlet Fermionic Dark Matter can be such a dark matter candidate, simultaneously providing the correct thermal relic density which is consistent with the WMAP data.
