Leptogenesis for Pedestrians / Buchmüller, Wilfried (Deutsches Elektronen Synchrotron DESY, Hamburg) ; Di Bari, P (IFAE, Universitat Autonoma de Barcelona, Bellaterra) ; Plümacher, M (CERN)
During the process of thermal leptogenesis temperature decreases by about one order of magnitude while the baryon asymmetry is generated. We present an analytical description of this process so that the dependence on the neutrino mass parameters becomes transparent. [...]

The Neutrino Mass Window for Baryogenesis / Buchmuller, W. (DESY) ; Di Bari, P. (Barcelona, IFAE) ; Plumacher, M. (CERN)
Interactions of heavy Majorana neutrinos in the thermal phase of the early universe may be the origin of the cosmological matter-antimatter asymmetry. This mechanism of baryogenesis implies stringent constraints on light and heavy Majorana neutrino masses. [...]

Testing SO(10)-inspired leptogenesis with low energy neutrino experiments / Di Bari, Pasquale (Southampton U. ; Sussex U.) ; Riotto, Antonio (INFN, Padua ; CERN)
We extend the results of a previous analysis of ours showing that, when both heavy and light flavour effects are taken into account, successful minimal (type I + thermal) leptogenesis with SO(10)-inspired relations is possible. Barring fine tuned choices of the parameters, these relations enforce a hierarchical RH neutrino mass spectrum that results into a final asymmetry dominantly produced by the next-to-lightest RH neutrino decays (N_2 dominated leptogenesis).

Full Boltzmann equations for leptogenesis including scattering / Hahn-Woernle, F (Munich, Max Planck Inst.) ; Plümacher, M (Munich, Max Planck Inst.) ; Wong, Y Y Y (CERN ; RWTH Aachen U.)
We study the evolution of a cosmological baryon asymmetry produced via leptogenesis by means of the full classical Boltzmann equations, without the assumption of kinetic equilibrium and including all quantum statistical factors. Beginning with the full mode equations we derive the usual equations of motion for the right-handed neutrino number density and integrated lepton asymmetry, and show explicitly the impact of each assumption on these quantities.
