A systematic halo-independent analysis of direct detection data within the framework of Inelastic Dark Matter

TL;DR

This paper conducts a halo-independent analysis of direct detection data for Inelastic Dark Matter, identifying conditions under which experimental results can be compatible without assuming specific WIMP velocity distributions.

Contribution

It introduces a systematic, minimal-assumption approach to reconcile conflicting direct detection signals within the IDM framework.

Findings

Compatibility between experiments can be achieved with specific WIMP and mass splitting values.

The analysis does not rely on detailed halo models, making results more robust.

Certain parameter regions allow for consistent IDM interpretations of experimental excesses.

Abstract

We present a systematic halo-independent analysis of available Weakly Interacting Massive Particles (WIMP) direct detection data within the framework of Inelastic Dark Matter (IDM). We show that, when the smallest number of assumptions is made on the WIMP velocity distribution in the halo of our Galaxy, it is possible to find values of the WIMP mass and the IDM mass splitting for which compatibility between present constraints and any of the three experiments claiming to see a WIMP excess among DAMA, CDMS-Si and CRESST can be achieved.
