Dark matter in supersymmetric models with axino LSP in Randall-Sundrum II brane model
arXiv:0805.0535 · doi:10.1088/1126-6708/2008/05/036
Abstract
The axino dark matter hypothesis in RSII brane model is studied. Within the framework of CMSSM we assume that the lightest neutralino or stau is the NLSP, and that the axino production has a single contribution from the NLSP decay. It is found that the axino can play the role of dark matter in the universe and we determine what the axino mass should be for different values of the five-dimensional Planck mass. An upper bound is obtained for the latter
