Baryogenesis by heavy-neutrino decay and sphaleron reprocessing of both baryon and lepton number is reconsidered, paying special attention to the flavour structure of the general evolution equations and developing an approximate but sufficiently accurate analytic solution to the prototype evolution equation. Two different models of neutrino masses are examined, based on an Abelian U(1) or a non-Abelian U(2) family symmetry. We show that a consistent picture of baryogenesis can emerge in both cases, although with significant differences.

Does thermal leptogenesis in a canonical seesaw rely on initial memory?
Flavor projection effects in density-matrix equations permit misaligned asymmetry components from N2 and N3 to survive N1 washout in hierarchical seesaw leptogenesis, dividing parameter space into four regimes under l...

Feasibility Study of Lepton Number Violation in Rare $B$ and $K$ Meson Decays
Dimension-7 lepton-number-violating operators can make B→Kνν and K→πνν observable only in flavor-hierarchical scenarios (first lepton generation decoupled) or with a cutoff near 100-200 GeV; otherwise baryon washout a...

Right-Handed Neutrino Production by an Axion-like Inflaton: Implications for Leptogenesis
A derivative-coupled axion-like inflaton can produce the heavy right-handed neutrinos whose decays explain the observed baryon asymmetry, with the required CP violation lower in the prompt-decay regime.

Insights on the Scale of Leptogenesis from Neutrino Masses and Neutrinoless Double-Beta Decay
In hierarchical seesaw leptogenesis, the required lightest heavy-neutrino mass sits between about 10^8 and 10^10 GeV for typical fine-tuning and can fall to 10^6 GeV with strong fine-tuning, as a function of the light...
