Flavoured resonant leptogenesis at sub-TeV scales
نویسندگان
چکیده
We consider sub-TeV scale flavoured resonant leptogenesis within the minimal type-I seesaw scenario with two right-handed singlet neutrinos $N_{1,2}$ forming a pseudo-Dirac pair, concentrating on case of masses pair having values $M_{1,2} \lesssim 100$ GeV. The when CP violating asymmetries in individual lepton charges $L_l$, $l=e,\mu,\tau$, and total charge $L$ Universe are generated $1 \leftrightarrow 2$ decay processes is investigated. show that successful possible for $M_{1,2}$ lying interval = (0.3 - 100)$ Our results also, particular, vanishing initial abundance, flavour effects can play an important role generation baryon asymmetry, leading to enhancement asymmetry by factor up $\sim 300$ respect "unflavoured" scenario.

TeV scale resonant leptogenesis from supersymmetry breaking
We propose a model of TeV-scale resonant leptogenesis based upon recent models of the generation of light neutrino masses from supersymmetry-breaking effects with TeV-scale right-handed (rhd) neutrinos, Ni. The model leads to large cosmological lepton asymmetries via the resonant behaviour of the one-loop self-energy contribution to Ni decay. Our model addresses the primary problems of previous...
متن کاملFlavoured Soft Leptogenesis
We study the impact of flavour in “soft leptogenesis” (leptogenesis induced by soft supersymmetry breaking terms). We address the question of how flavour effects can affect the region of parameters in which successful soft leptogenesis induced by CP violation in the right-handed sneutrino mixing is possible. We find that for decays which occur in the intermediate to strong washout regimes for a...
متن کاملLeptogenesis at the TeV scale
We present a general description of the problems encountered when attempting to build a simple model of leptogenesis and hence of baryogenesis at an energy scale as low as 1-10 TeV. We consider three possible lepton asymmetry enhancement mechanisms in the out-of-equilibrium decay scenario, emphasizing the three body decay mechanism as most natural. A new model based on the three body decays of ...
متن کاملPurely Flavored Leptogenesis at the Tev Scale
I study variations of the standard leptogenesis scenario that can arise if an additional mass scale related to the breaking of some new symmetry is present below the mass MN1 of the lightest right-handed Majorana neutrino. I present a particular realization of this scheme that allows for leptogenesis at the TeV scale. In this realization the baryon asymmetry is exclusively due to flavor effects.
متن کاملOn Resonant Leptogenesis
It has been recently shown that the quantum Boltzmann equations may be relevant for the leptogenesis scenario. In particular, they lead to a timedependent CP asymmetry which depends upon the previous dynamics of the system. This memory effect in the CP asymmetry is particularly important in resonant leptogenesis where the asymmetry is generated by the decays of nearly mass-degenerate right-hand...
