Supersymmetry with Light Dark Matter confronting the recent CDMS and LHC Results

TL;DR

This paper examines MSSM models with light neutralino dark matter, demonstrating they can meet current experimental constraints and align with recent CDMS and LHC findings.

Contribution

It shows that light neutralino scenarios with scalar bottom quarks near in mass can satisfy all experimental constraints and explain recent dark matter detection results.

Findings

Light neutralino (~10 GeV) scenarios are viable under current constraints.

Such scenarios can explain recent CDMS dark matter detection results.

Models remain consistent with LHC, LEP, and flavor physics constraints.

Abstract

We revisit MSSM scenarios with light neutralino as a dark matter candidate in view of the latest LHC and dark matter direct and indirect detection experiments. We show that scenarios with a very light neutralino (~ 10 GeV) and a scalar bottom quark close in mass, can satisfy all the available constraints from LEP, Tevatron, LHC, flavour and low energy experiments and provide solutions in agreement with the bulk of dark matter direct detection experiments, and in particular with the recent CDMS results.
