Low-scale leptogenesis in the scotogenic model: spectator processes and benchmark points
J. Racker
We study leptogenesis from the decay of the lightest sterile neutrino in the scotogenic model with a scalar dark matter candidate. Our analysis focuses on the possible exponential…
On low-scale baryogenesis from three-body decays
F. Domínguez, J. Racker
Baryogenesis at the TeV scale from CP-violating decays of a massive particle requires some way to avoid the washouts from processes closely related to the existence of CP violation…
Washout processes in post-sphaleron baryogenesis from way-out-of-equilibrium decays
J. Racker
We study washout processes in post-sphaleron baryogenesis, a mechanism where the matter-antimatter asymmetry is generated in the decay of exotic particles after the electroweak pha…
On different approaches to freeze-in and freeze-out leptogenesis with quasi-degenerate neutrinos
J. Racker
We compare two approaches for determining the generation of lepton asymmetry during production and decay of quasi-degenerate neutrinos, namely the density matrix formalism and a re…
CP violation in mixing and oscillations for leptogenesis II: the highly degenerate case
J. Racker
We extend to the highly degenerate case a recent approach for analyzing the sources of CP violation in baryogenesis models with quasi-degenerate neutrinos. In this approach an expa…
CP violation in mixing and oscillations for leptogenesis with quasi-degenerate neutrinos
J. Racker
We study the sources of CP violation for baryogenesis models with quasi-degenerate neutrinos. Our approach is to use the renormalized propagator in a quantum field theory model of…
