• 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 ...
