Dr. Stefan F¨orsteTag der Promotion: 27.7.2010Erscheinungsjahr: 20102AbstractWestudythecollidersignalsaswellasDarkMattercandidatesinsupersymmetricmodels.We show that the collider signatures from a supersymmetric Grand Unification modelbasedontheSO(10)gaugegroupcanbedistinguishablefromthosefromthe(constrained)minimalsupersymmetricStandardModel,eventhoughtheysharesomecommonfeatures.The N = 2 supersymmetry has the charateristically distinct phenomenology, due to theDirac nature of gauginos, as well as the extra adjoint scalars. We compute the cold DarkMatter relic density including a class of one-loop corrections. Finally, we discuss thedetectability of neutralino Dark Matter candidate of the SO(10) model by the direct andindirect Dark Matter search experiments.3First of all, I appreciate Manuel Drees for his patience during the whole period of myPh. D. He indeed deserves to be called my ’Doktorvater’.
