Basis invariant measure of CP-violation and renormalization.
Hohenegger, Andreas; Kartavtsev, Alexander (Journal article; Peer reviewed, 2015-08)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 for the minimal subtraction and on-shell ... -
Leptogenesis in crossing and runaway regimes.
Hohenegger, Andreas; Kartavtsev, Alexander (Journal article; Peer reviewed, 2014-07)We study the impact of effective thermal masses and widths on resonant lepto-genesis. We identify two distinct possibilities which we refer to as ‘crossing’ and ‘runaway’ regimes. In the runaway regime the mass difference ...
