Neutralino Dark Matter in Light Higgs Boson Scenario

Understand

Phenomenology of neutralino dark matter in the minimal supersymmetric model is discussed for a scenario where the lightest Higgs boson mass is lighter than 114.4 GeV.

• We show that the scenario is consistent not only with many collider experiments but also with the observed relic abundance of dark matter.
• The allowed region may be probed by experiments of Bs to mu^+ mu^- in near future.
• The scenario predicts a large scattering cross section between the dark matter and ordinary matter and thus it may be tested in present direct detection experiments of dark matter.
