Gravitino Dark Matter and general neutralino NLSP
Laura Covi, Jasper Hasenkamp, Stefan Pokorski +1
We study the scenario of gravitino DM with a general neutralino NLSP in a model independent way. We consider all neutralino decay channels and compare them with the most recent BBN…
Neutralino Dark Matter in the USSM
J. Kalinowski, S. F. King, J. P. Roberts
This paper provides a comprehensive discussion of neutralino dark matter within classes of extended supersymmetric models referred to as the USSM containing one additional SM singl…
The Fine-Tuning Price of Neutralino Dark Matter in Models with Non-Universal Higgs Masses
John Ellis, S. F. King, J. P. Roberts
We study the amounts of fine-tuning of the parameters of the MSSM with non-universal soft supersymmetry-breaking contributions to the Higgs masses (the NUHM) that would be required…
Natural Dark Matter in SUSY GUTs with Non-universal Gaugino Masses
S. F. King, J. P. Roberts, D. P. Roy
We consider neutralino dark matter within the framework of SUSY GUTs with non-universal gaugino masses. In particular we focus on the case of SU(5) with a SUSY breaking F-term in t…
Natural Dark Matter from Type I String Theory
S. F. King, J. P. Roberts
We study neutralino dark matter within a semi-realistic type I string model, where supersymmetry breaking arises from F-terms of moduli fields parameterised in terms of Goldstino a…
Natural Implementation of Neutralino Dark Matter
S. F. King, J. P. Roberts
The prediction of neutralino dark matter is generally regarded as one of the successes of the Minimal Supersymmetric Standard Model (MSSM). However the successful regions of parame…
