Lorenzo Calibbi, Toshihiko Ota, Yasutaka Takanishi
TL;DR
This paper updates the analysis of light neutralino dark matter in the MSSM considering recent LHC results, showing that new constraints challenge the parameter space compatible with some direct detection experiments.
Contribution
It provides an updated assessment of light neutralino dark matter viability in the MSSM incorporating the latest LHC data.
Findings
LHC constraints exclude most parameter regions compatible with DAMA and CoGENT.
Recent LHC results significantly limit light neutralino dark matter scenarios.
The parameter space for light neutralino dark matter is strongly constrained by current collider data.
Abstract
We discuss the scenario of light neutralino dark matter in the minimal supersymmetric standard model, which is motivated by the results of some of the direct detection experiments --- DAMA, CoGENT, and CRESST. We update our previous analysis with the latest results of the LHC. We show that new LHC constraints disfavour the parameter region that can reproduce the results of DAMA and CoGENT.
