Leptogenesis via Higgs Condensate Relaxation
  An epoch of Higgs relaxation may occur in the early universe during or
immediately following postinflationary reheating. It has recently been pointed
out that leptogenesis may occur in minimal extensions of the Standard Model
during this epoch. We analyse Higgs relaxation taking into account the effects
of perturbative and non-perturbative decays of the Higgs condensate, and we
present a detailed derivation of the relevant kinetic equations and of the
relevant particle interaction cross sections. We identify the parameter space
in which a sufficiently large asymmetry is generated.
