WIMP mass from direct, indirect dark matter detection experiments and colliders: A complementary and model-independent approach

TL;DR

This paper explores how direct, indirect, and collider experiments can collectively determine dark matter particle properties, especially WIMP mass, in a model-independent manner, highlighting their complementary strengths.

Contribution

It demonstrates a combined, model-independent approach to identify WIMP mass using direct detection, indirect detection, and collider data, emphasizing their complementary roles.

Findings

Direct detection probes light WIMPs effectively.

GLAST enhances precision for certain cross-sections and profiles.

ILC is crucial for heavier WIMP mass reconstruction.

Abstract

We study the possibility of identifying dark matter properties from direct (XENON100) and indirect (GLAST) detection experiments. In the same way, we examine the perspectives given by the next generation of colliders (ILC). All this analysis is done following a model-independent approach. We have shown that the three detection techniques can act in a highly complementary way. whereas direct detection experiments will probe efficiently light WIMPs, given a positive detection (at the 10% level for $m_{\chi} \sim 50$ GeV), GLAST will be able to confirm and even increase the precision in the case of a NFW profile, for a WIMP-nucleon cross-section $\sigma_{\chi-p}<10^{-8}$ pb. However, for heavier WIMP ($\sim 175$ GeV), the ILC will lead the reconstruction of the mass.
