F. Mahmoudi, A. Arbey, M. Battaglia
TL;DR
This paper demonstrates that within the MSSM framework, light neutralino dark matter particles can still be viable candidates, consistent with recent experimental signals and constraints from various physics experiments.
Contribution
It provides a comprehensive analysis showing the feasibility of light neutralino dark matter in MSSM under current experimental constraints.
Findings
Light neutralinos can explain signals from DAMA, COGENT, and CRESST.
Viable MSSM scenarios with light neutralinos are consistent with collider and astrophysical data.
The characteristics of these scenarios are analyzed in detail.
Abstract
Three dark matter direct detection experiments, DAMA, COGENT and CRESST, have reported a possible signal of WIMP interaction corresponding to very light particles, close to the edge of the XENON 100 and CDMS sensitivity. Imposing the latest constraints from colliders, flavour physics, electroweak precision tests and direct and indirect dark matter searches, we show that viable MSSM scenarios with a light neutralino, in agreement with all the present data, are feasible. An analysis of the characteristics of the resulting scenarios will be presented.
