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,…
Resonant enhancement in leptogenesis
P. S. Bhupal Dev, Mathias Garny, Juraj Klaric +2
Vanilla leptogenesis within the type I seesaw framework requires the mass scale of the right-handed neutrinos to be above 10^9 GeV. This lower bound can be avoided if at least two…
Flavor effects in leptogenesis
P. S. Bhupal Dev, Pasquale Di Bari, Bjorn Garbrecht +3
Flavor effects can have a significant impact on the final estimate of the lepton (and therefore baryon) asymmetry in scenarios of leptogenesis. It is therefore necessary to account…
Consistent description of field theories with non-Hermitian mass terms
Jean Alexandre, Peter Millington, Dries Seynaeve
We review how to describe a field theory that includes a non-Hermitian mass term in the region of parameter space where the Lagrangian is -symmetric. The discrete symmetries of…
Non-perturbative aspects of galileon duality
Peter Millington, Florian Niedermann, Antonio Padilla
We study quantum aspects of the galileon duality, especially in the case of a particular interacting galileon theory that is said to be dual to a free theory through the action of…
Symmetries and conservation laws in non-Hermitian field theories
Jean Alexandre, Peter Millington, Dries Seynaeve
Anti-Hermitian mass terms are considered, in addition to Hermitian ones, for PT-symmetric complex-scalar and fermionic field theories. In both cases, the Lagrangian can be written…
