Abstract:
Vanilla leptogenesis within the type I seesaw framework requires the mass scale of the right-handed neutrinos to be above [Formula: see text] GeV. This lower bound can be avoided if at least two of the sterile states are almost mass degenerate, which leads to an enhancement of the decay asymmetry. Leptogenesis models that can be tested in current and upcoming experiments often rely on this resonant enhancement, and a systematic and consistent description is therefore necessary for phenomenological applications. In this paper, we give an overview of different methods that have been used to study the saturation of the resonant enhancement when the mass difference becomes comparable to the characteristic width of the Majorana neutrinos. In this limit, coherent flavor transitions start to play a decisive role, and off-diagonal correlations in flavor space have to be taken into account. We compare various formalisms that have been used to describe the resonant regime and discuss under which circumstances the resonant enhancement can be captured by simplified expressions for the CP asymmetry. Finally, we briefly review some of the phenomenological aspects of resonant leptogenesis.

Abstract:
In this paper, we study a two-loop induced radiative neutrino model at TeV scale with global [Formula: see text] symmetry, in which we analyze dark matter and resonant leptogenesis. The model includes two kinds of dark matter candidates. We discuss what kind of dark matter can satisfy the observed relic density as well as the current direct detection bound, and be simultaneously compatible with the leptogenesis. We also discuss whether our resonant leptogenesis can be differentiated from the other scenarios at TeV scale or not.

Abstract:
In light of the latest neutrino data, we revisit a minimal seesaw model with the Frampton–Glashow–Yanagida ansatz. Renormalization-group running effects on neutrino masses and flavor mixing parameters are discussed and found to essentially have no impact on testing such a minimal scenario in low-energy neutrino experiments. However, since renormalization-group running can modify neutrino mixing parameters at high energies, it does affect the leptogenesis mechanism, which is responsible for the observed matter–antimatter asymmetry in our Universe. Furthermore, to ease the conflict between the naturalness argument and the successful leptogenesis, a special regime for resonant leptogenesis is also emphasized.

Abstract:
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 transition de phase T, les neutrinos stériles obtiennent une masse M. Deux mécanismes sont considérés. Pour des neutrinos stériles non-relativistes M>T déviant de l'équilibre lors de la transition de phase, l'asymétrie leptonique est créée lors de leurs désintégrations. La rapidité de la transition permet d'avoir une population de neutrinos stériles initiale plus importante que dans le cas standard et améliore la création d'asymétrie. L'analyse numérique permet de décrire l'espace des paramètres où la leptogénèse est réussie. Pour des neutrinos stériles relativistes M
The baryon asymmetry in our Universe is an unsolved problem in cosmology. A popular approach for explaining it is leptogenesis with sterile neutrinos, which are particles motivated in order to explain the masses of active neutrinos in the Standard Model. It is possible to include in these scenarios a cosmological phase transition which gives rise to the sterile neutrino masses. This idea is phenomenologically interesting, as such a phase transition could produce detectable gravitational waves. At the temperature T of the phase transition, sterile neutrinos acquire a mass M. Two mechanisms are considered. For non-relativistic sterile neutrinos M>T, deviating from equilibrium due to the phase transition, they will quickly decay and produce a lepton asymmetry. The rapidity of the phase transition allows a larger sterile neutrino population than in usual scenarios and enhances the created asymmetry. Numerical analyses describe the successful regions in parameter space for leptogenesis. For relativistic sterile neutrinos M
