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,…
Electric Dipole Moments in the MSSM at Large tan(beta)
Durmus Demir, Oleg Lebedev, Keith A. Olive +2
Within the minimal supersymmetric standard model (MSSM), the large tan(beta) regime can lead to important modifications in the pattern of CP-violating sources contributing to low e…
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…
Sugra Dark Matter
Keith A. Olive
I review the phenomenological and cosmological constraints on the parameter space associated with the Constrained Minimal Supersymmetric Standard Model (CMSSM). The effect of the r…
Updated Post-WMAP Benchmarks for Supersymmetry
M. Battaglia, A. De Roeck, J. Ellis +3
We update a previously-proposed set of supersymmetric benchmark scenarios, taking into account the precise constraints on the cold dark matter density obtained by combining WMAP an…
