Unitarity and CP violation in leptogenesis at NLO: general considerations and top Yukawa contributions

Abstract With an emphasis on unitarity and CPT requirements, we study the inclusion of CP-violating processes in baryogenesis at next-to-leading order, particularly those involving the top Yukawa interaction in leptogenesis. We show that there are more contributions than previously considered, but a...
