Determining the WIMP mass using the complementarity between direct and indirect searches and the ILC

TL;DR

This paper explores how combining direct detection, indirect detection via gamma-ray observations, and collider experiments can improve the determination of WIMP dark matter properties, especially mass, across different detection methods.

Contribution

It introduces a comprehensive approach to determine WIMP mass by integrating data from direct detection, gamma-ray observations, and collider experiments, highlighting their complementarity.

Findings

Direct detection is effective for light WIMPs below 50 GeV.

GLAST can enhance WIMP mass measurement, especially with NFW profile.

ILC can produce WIMPs and help constrain their mass.

Abstract

We study the possibility of identifying dark matter properties from XENON-like 100 kg experiments and the GLAST satellite mission. We show that whereas direct detection experiments will probe efficiently light WIMPs, given a positive detection (at the 10% level for $m_{\chi} \lesssim 50$ 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 $\sigma_{\chi-p} \lesssim 10^{-8}$ pb. We also predict the rate of production of a WIMP in the next generation of colliders (ILC), and compare their sensitivity to the WIMP mass with the XENON and GLAST projects.
