Status of rates and rate equations for thermal leptogenesis
Simone Biondini, Dietrich Bodeker, Nora Brambilla +8
In many realizations of leptogenesis, heavy right-handed neutrinos play the main role in the generation of an imbalance between matter and antimatter in the early Universe. Hence,…
Quantum corrections to inflation: the importance of RG-running and choosing the optimal RG-scale
Matti Herranen, Andreas Hohenegger, Asgeir Osland +1
We demonstrate the importance of correctly implementing RG-running and choosing the RG-scale when calculating quantum corrections to inflaton dynamics. We show that such correction…
Leptogenesis in crossing and runaway regimes
A. Hohenegger, A. Kartavtsev
We study the impact of effective thermal masses and widths on resonant leptogenesis. We identify two distinct possibilities which we refer to as crossing and runaway regimes. In th…
Systematic approach to thermal leptogenesis
T. Frossard, M. Garny, A. Hohenegger +2
In this work we study thermal leptogenesis using non-equilibrium quantum field theory. Starting from fundamental equations for correlators of the quantum fields we describe the ste…
Leptogenesis from first principles in the resonant regime
Mathias Garny, Alexander Kartavtsev, Andreas Hohenegger
The lepton asymmetry generated by the out-of-equilibrium decays of heavy Majorana neutrinos with a quasi-degenerate mass spectrum is resonantly enhanced. In this work, we study thi…
Medium corrections to the CP-violating parameter in leptogenesis
M. Garny, A. Hohenegger, A. Kartavtsev
In two recent papers, arXiv:0909.1559 and arXiv:0911.4122, it has been demonstrated that one can obtain quantum corrected Boltzmann kinetic equations for leptogenesis using a top-d…
