Resumen
We review the current status of the leptogenesis scenario originally proposed by Akhmedov, Rubakov and Smirnov (ARS). It takes place in the parametric regime where the right-handed neutrinos are at the electroweak scale or below and the CP-violating effects are induced by the coherent superposition of different right-handed mass eigenstates. Two main theoretical approaches to derive quantum kinetic equations, the Hamiltonian time evolution as well as the Closed-Time-Path technique are presented, and we discuss their relations. For scenarios with two right-handed neutrinos, we chart the viable

Resumen
The focus of this paper 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) mechanism allows for heavy neutrinos in the GeV range, this opens up a plethora of possible experimental tests, e.g. at neutrino oscillation experiments, neutrinoless double beta decay, and direct searches for neutral heavy leptons at future facilities. In contrast, testing leptogenesis from out-of-equilibrium decays is a quite difficult task. We comment

Resumen
Abstract Extensions of the Standard Model (SM) with sterile neutrinos are well motivated from the observed oscillations of the light neutrinos and they have shown to successfully explain the Baryon Asymmetry of the Universe (BAU) through, for instance, the so-called ARS leptogenesis. Sterile neutrinos can be added in minimal ways to the SM, but many theories exist where sterile neutrinos are not the only new fields. Such theories often include scalar bosons, which brings about the possibility of further interactions between the sterile neutrinos and the SM. In this paper we consider an extensi

Resumen
L'asymétrie entre matière et antimatière est un problème non résolu de la cosmologie. Une approche populaire pour l'expliquer est la leptogénèse avec des neutrinos stériles, qui sont des particules motivées expérimentalement pour expliquer les masses des neutrinos actifs du Modèle Standard. Il est possible d'inclure dans les scénarios de leptogénèse une transition de phase cosmologique qui donne leur masse aux neutrinos stériles. Cette idée est intéressante phénoménologiquement, car une transition de phase produit des ondes gravitationnelles pouvant être détectées. À la température de la trans

Resumen
Chapter 4 deals with the stability of the proton, hence of hydrogen, and how to reconcile that stability with the baryon number nonconservation (or baryon conservation) needed to establish a matter–antimatter imbalance in the infant universe. Sakharov’s three conditions for establishing a matter–antimatter imbalance are presented. Grand unified theories and experimental searches for proton decay are described. The concept of spontaneous symmetry breaking is introduced in describing the electroweak phase transition in the infant universe. That transition is treated as the potential site for int

Resumen
In the context of a model that combines the type I and type II seesaw mechanisms, we investigate two different kinds of neutrino mass matrices that enable the production of tiny neutrino masses. The goal of this work is to examine how leptogenesis contributes to the matter-antimatter asymmetry's origin. The first mass matrix is of the tri-bimaximal (TBM) type, which consistently produces a reactor mixing angle that is non-zero, and is based on the type I seesaw mechanism. Next, we study the type II seesaw mass matrix with the goal of introducing perturbations from the TBM mixing pattern and ma
