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…

Ultraviolet freeze-in baryogenesis

Andreas Goudelis, Dimitrios Karamitros, Pantelis Papachristou +1

We study a mechanism through which the cosmic dark matter density can be explained simultaneously with the observed baryon asymmetry of the Universe. At the core of our proposal li…

Mechanism for baryogenesis via feebly interacting massive particles

Andreas Goudelis, Pantelis Papachristou, Vassilis C. Spanos

We present a simple mechanism which allows the simultaneous generation of the baryon asymmetry of the Universe along with its dark matter content. To this goal, we employ the out-o…

Comparison of approximate to exact next-to-next-to leading order corrections for Higgs and pseudoscalar Higgs boson production

A. P. Contogouris, P. K. Papachristou

Recently obtained NNLO exact corrections for Higgs and Pseudoscalar Higgs boson production in hadron colliders are compared with approximate ones. As shown before, it is found that…

A Model for the Color Glass Condensate Versus Jet Quenching

A. Contogouris, F. K. Diakonos, P. K. Papachristou

A model for the Color Glass Condensate as opposed to jet quenching is proposed for the explanation of the presently available RHIC data. Good fits to these data are presented. A cl…
