Leptogenesis withoutCPviolation at low energies

M. N. Rebelo

Open full text 66 citations

Abstract

In this paper we give a class of examples where the decays of the heavy Majorana neutrinos may violate CP even if there is no CP violation at low energies, i.e., where leptogenesis can take place without Majorana- or Dirac-type CP phases at low energies.
