High Energy Theory Lunchtime Seminar

We study supersymmetric models that include a viable dark
matter candidate and that generate the observed baryon asymmetry of the Universe at the electro-weak phase transition. We focus on the possibility of probing these models with searches for the permanent electric dipole moment (EDM) of the electron, with direct and indirect dark matter searches, with high energy colliders and with Gravitational Wave detection. We point out that the lightest neutralino might play a key role for the generation of both baryonic and dark matter. We show that models
overproducing relic neutralinos put tighter constraints on successful electro-weak baryogenesis. We present new results on two-loop electric dipole moments and investigate in detail the entire parameter space of the minimal supersymmetric extension of the standard model where electro-weak baryogenesis can account for the baryon asymmetry of the universe. We claim that the ensemble of experimental tests we consider makes ours a
testable framework for the origin of both the dark matter and the baryonic matter-antimatter asymmetry in the Universe.
