Quantum Leptogenesis I
A. Anisimov, W. Buchmuller, M. Drewes +1
Thermal leptogenesis explains the observed matter-antimatter asymmetry of the universe in terms of neutrino masses, consistent with neutrino oscillation experiments. We present a f…
Thermal production of relativistic Majorana neutrinos: Strong enhancement by multiple soft scattering
Alexey Anisimov, Denis Besak, Dietrich Bodeker
The production rate of heavy Majorana neutrinos is relevant for models of thermal leptogenesis in the early Universe. In the high temperature limit the production can proceed via t…
Leptogenesis from Quantum Interference in a Thermal Bath
A. Anisimov, W. Buchmuller, M. Drewes +1
Thermal leptogenesis explains the observed matter-antimatter asymmetry of the universe in terms of neutrino masses, consistent with neutrino oscillation experiments. We present a f…
Nonequilibrium Dynamics of Scalar Fields in a Thermal Bath
A. Anisimov, W. Buchmueller, M. Drewes +1
We study the approach to equilibrium for a scalar field which is coupled to a large thermal bath. Our analysis of the initial value problem is based on Kadanoff-Baym equations whic…
Cold Dark Matter from heavy Right-Handed neutrino mixing
Alexey Anisimov, Pasquale Di Bari
We show that, within the see-saw mechanism, an almost decoupled RH neutrino species N_DM with mass M_DM \gtrsim 100 GeV can play the role of Dark Matter (DM). The N_DM's can be pro…
Inflaton mass in the nuMSM inflation
Alexey Anisimov, Yannick Bartocci, Fedor L. Bezrukov
We analyse the reheating in the modification of \nuMSM (Standard Model with three right handed neutrinos with masses below the electroweak scale) where the sterile neutrino providi…
