Basis invariant measure of CP-violation and renormalization
A. Hohenegger, A. Kartavtsev
We analyze, in the context of a simple toy model, for which renormalization schemes the CP-properties of bare Lagrangian and its finite part coincide. We show that this is the case…

Quantum corrections to leptogenesis from the gradient expansion
M. Garny, A. Hohenegger, A. Kartavtsev
Using the closed-time-path formalism we quantify gradient corrections to the kinetic equations for leptogenesis, that are neglected in the standard Boltzmann approach. In particula…

Deriving Boltzmann Equations from Kadanoff-Baym Equations in Curved Space-Time
A. Hohenegger, A. Kartavtsev, M. Lindner
To calculate the baryon asymmetry in the baryogenesis via leptogenesis scenario one usually uses Boltzmann equations with transition amplitudes computed in vacuum. However, the hot…
