Freeze-in baryogenesis and early matter domination
Ioannis Dalianis, Andreas Goudelis, Dimitrios Karamitros +2
The freeze-in mechanism has been shown to allow the simultaneous generation of cosmic dark matter and a viable matter-antimatter asymmetry in the universe. When the underlying inte…
Tri-Resonant Leptogenesis
P. Candia da Silva, D. Karamitros, T. McKelvey +1
We present a class of leptogenesis models where the light neutrinos acquire their observed mass through a symmetry-motivated construction. We consider an extension of the Standard…
Effective Theory for Electroweak Doublet Dark Matter
Athanasios Dedes, Dimitrios Karamitros, Vassilis C. Spanos
We perform a detailed study of an effective field theory which includes the Standard Model particle content extended by a pair of Weyl fermionic SU(2)-doublets with opposite hyperc…
Doublet-Triplet Fermionic Dark Matter
Athanasios Dedes, Dimitrios Karamitros
We extend the Standard Model (SM) by adding a pair of fermionic SU(2)-doublets with opposite hypercharge and a fermionic SU(2)-triplet with zero hypercharge. We impose a discrete Z…
