Gravitino Dark Matter in the CMSSM
John Ellis, Keith A. Olive, Yudi Santoso +1
We consider the possibility that the gravitino might be the lightest supersymmetric particle (LSP) in the constrained minimal extension of the Standard Model (CMSSM). In this case,…
Likelihood Analysis of the CMSSM Parameter Space
John Ellis, Keith A. Olive, Yudi Santoso +1
We present a likelihood analysis of the parameter space of the constrained minimal supersymmetric extension of the Standard Model (CMSSM), in which the input scalar masses m_0 and…
High-Energy Constraints on the Direct Detection of MSSM Neutralinos
John Ellis, Keith A. Olive, Yudi Santoso +1
The requirement that the MSSM remain an acceptable effective field theory up to energies beyond the weak scale constrains the sparticle spectrum, and hence the permissible ranges o…
The MSSM with Non-Universal Higgs Masses
Yudi Santoso
I review a generalization of CMSSM/mSUGRA model in which the Higgs masses are let to be free, namely the Non Universal Higgs Masses (NUHM) model. In our study we explore this model…
Phenomenological Constraints on Patterns of Supersymmetry Breaking
J. Ellis, K. A. Olive, Y. Santoso +1
Specific models of supersymmetry breaking predict relations between the trilinear and bilinear soft supersymmetry breaking parameters A_0 and B_0 at the input scale. In such models…
Supersymmetric Dark Matter in Light of WMAP
J. Ellis, K. A. Olive, Y. Santoso +1
We re-examine the parameter space of the constrained minimal supersymmetric extension of the Standard Model (CMSSM), taking account of the restricted range of Ω_{CDM} h^2 consisten…
Direct Detection of Dark Matter in the MSSM with Non-Universal Higgs Masses
J. Ellis, A. Ferstl, K. A. Olive +1
We calculate dark matter scattering rates in the minimal supersymmetric extension of the Standard Model (MSSM), allowing the soft supersymmetry-breaking masses of the Higgs multipl…
