Item Detecting Dark Matter In The MSSM With Non-Universal Higgs Masses(2009-02) Sandick, P.; Sandick, PearlWe discuss the direct detection prospects for neutralino dark matter via elastic scattering in variations of the MSSM with non-universal supersymmetry-breaking contributions to the Higgs masses Taking as our starting point the CMSSM, in which supersymmetry-breaking contributions to all scalar masses are universal, we examine scenarios in which both Higgs scalar masses are non-universal by the same amount (NUHM1) and scenarios in which the Higgs scalar masses are independently non-universal (NUHM2)Item Neutralino Dark Matter In MSSM Models With Non-Universal Higgs Masses(2010-06) Sandick, P.; Sandick, PearlWe consider the Minimal Supersymmetric Standard Model (MSSM) with varying amounts of non-universality in the soft supersymmetry-breaking contributions to the Higgs scalar masses. In addition to the constrained MSSM (CMSSM) in which these are universal with the soft supersymmetry-breaking contributions to the squark and slepton masses at the input GUT scale, we consider scenarios in which both the Higgs masses are non-universal by the same amount (NUHM1), and scenarios in which they are independently non-universal (NUHM2). As the lightest neutralino is a dark matter candidate, we demand that the relic density of neutralinos not be in conflict with measurements by WMAP and others, and examine the viable regions of parameter space. Prospects for direct detection of neutralino dark matter via elastic scattering in these scenarios are discussed.
