Low Scale Leptogenesis and the Perspectives to Test it in the Laboratory

Marco Drewes

Right-handed Majorana neutrinos can simultaneously explain the light neutrinos via the seesaw mechanism and generate the baryon asymmetry of the universe through leptogenesis. If their Majorana masses are at or below the electroweak scale they can be searched for in collider and fixed target experiments. We study the viable leptogenesis parameter space in this region to make predictions for the heavy neutrino properties, such as their mass spectrum, flavour mixing pattern and CP-properties. If any heavy neutral leptons are found in the laboratory, combining different observables allows to test whether these particles can indeed be responsible for baryogenesis and the neutrino masses.
