Washout processes in post-sphaleron baryogenesis from way-out-of-equilibrium decays

Autor: J. Racker

Publikováno v: European Physical Journal C: Particles and Fields, Vol 84, Iss 5, Pp 1-8 (2024)

Abstract We study washout processes in post-sphaleron baryogenesis, a mechanism where the matter–antimatter asymmetry is generated in the decay of exotic particles after the electroweak phase transition. In particular we focus, in a quite model ind

CP violation in mixing and oscillations for leptogenesis. Part II. The highly degenerate case

Autor: J. Racker

Publikováno v: Journal of High Energy Physics, Vol 2021, Iss 11, Pp 1-15 (2021)

Abstract We extend to the highly degenerate case a recent approach for analyzing the sources of CP violation in baryogenesis models with quasi-degenerate neutrinos. In this approach an expansion of the resummed propagator around the poles is plugged

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

Autor: J. Racker

Publikováno v: Journal of High Energy Physics, Vol 2019, Iss 2, Pp 1-18 (2019)

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 mo

The focus of this chapter lies on the possible experimental tests of leptogenesis scenarios. We consider both leptogenesis generated from oscillations, as well as leptogenesis from out-of-equilibrium decays. As the Akhmedov-Rubakov-Smirnov (ARS) mech
