Light neutralino in the MSSM: A playground for dark matter, flavor physics and collider experiments

Abstract:

We investigate the constraints to the light neutralino dark matter scenario in the minimal supersymmetric standard model from available experimental observations such as decays of B and K meson, relic dark matter abundance, and the search for neutralino and Higgs production at colliders. We find that two regions of the MSSM parameter space fulfill all the constraints: a fine-tuned strip with large tan β where the lightest neutralino can be as light as 8GeV, and a low tan β region providing a neutralino mass larger than 16GeV. The large tan β strip, which can be compatible with recently reported signals from direct detection experiments, can be fully tested by means of low-energy observables and, in particular, by Bs → μμ and Higgs bosons searches at the LHC within the upcoming months. © SISSA 2011.
