Mass Ordering of Third Generation Sleptons in a Trilinear-Augmented Gaugino Mediated Supersymmetry-Breaking Scenario
MetadataVis full innførsel
In this thesis, we are exploring the particle spectrum of trilinear-augmented gaugino mediation. In particular, we calculate the masses of the stau and the tau sneutrino in a section of the parameter space in which one is found to be the NLSP, while being very nearly mass-degenerate to the other. We attempt to understand the mechanisms behind this small mass difference at tree-level, and discuss how the situation changes by going up to 1-loop level.
