# Model Independent analysis of MeV scale dark matter: II. Implications from $e^-e^+$ colliders and Direct Detection

## TL;DR

This paper explores the potential for detecting sub-GeV dark matter particles through direct detection experiments and low-energy colliders, highlighting unexplored parameter space that could lead to discoveries.

## Contribution

It provides a model-independent analysis of MeV-scale dark matter, identifying parameter regions accessible to current and upcoming experiments.

## Key findings

- Large parameter space remains unconstrained by existing astrophysical data.
- Certain regions of parameter space are accessible to CRESST-II and Belle-II.
- Potential for discovery at direct detection and collider experiments is significant.

## Abstract

Dark matter particles with masses in the sub-GeV range have escaped severe constraints from direct detection experiments such as LUX, PANDAX-II and XENON100 as the corresponding recoil energies are, largely, lower than the detector thresholds. In a companion paper, we demonstrated, in a model independent approach, that a significantly large fraction of the parameter space escapes the cosmological and astrophysical constraints. We show here, though, that the remaining parameter space lends itself to the possibility of discovery at both direct detection experiments (such as CRESST-II) as well as in a low-energy collider such as Belle-II.
