Two components of dark matter in the DAMA data

TL;DR

The paper suggests that DAMA data reveal two distinct dark matter components, one orbiting the galactic center and another emitted from it, with their ratio inferred from annual variation patterns.

Contribution

It introduces a novel interpretation of DAMA data indicating two separate dark matter components and provides a method to determine their ratio based on yearly variation.

Findings

Evidence for two dark matter components in DAMA data

Quantitative ratio of the two components derived from annual variation

Implication of different origins for the dark matter components

Abstract

It is shown that the DAMA data indicate two dark matter components, one that circulates around the galactic center (GC) and another that is emitted from the GC. From the location of the maximum yearly variation, one can compute the ratio of the two components.
