Constraining supersymmetry using the relic density and the Higgs boson

Abstract : Recent measurements by Planck, LHC experiments, and Xenon100 have significant impact on supersymmetric models and their model parameters. With a special emphasis on these measurements we study the mSUGRA and TeV-scale MSSM parameter spaces using SFitter. The allowed structures in the parameter spaces are largely defined by different mechanisms of dark matter annihilation in combination with the light Higgs mass prediction. In mSUGRA the pseudoscalar Higgs funnel and stau co-annihilation processes are still avoiding experimental pressure. In the MSSM stau co-annihilation, the light Higgs funnel, a mixed bino--higgsino region including the heavy Higgs funnel, and a large higgsino region predict the correct relic density. Volume effects and changes in the model parameters impact the extracted mSUGRA and MSSM parameter regions in the Bayesian analysis.
