Leptogenesis via preheating ∗
Leptogenesis constitues a very simple scenario to achieve the baryon asymmetry that we observe today. It requires only the presence of right handed neutrinos (which arise very naturally in many extensions of the Standard Model) and depends crucially on the mechanism responsible for their production. In particular, when their mass exceeds the inflaton mass (10 GeV in chaotic inflation) only non ...
متن کاملProduction of massive fermions at preheating and leptogenesis
We present a complete computation of the inflaton decay into very massive fermions during preheating, including back-reaction effects. We show that heavy fermions are produced very efficiently up to masses of order 10–10 GeV; the accessible mass range is thus even broader than the one for heavy bosons. We apply our findings to the leptogenesis scenario, proposing a new version of it, in which t...
متن کاملBaryogenesis via leptogenesis
We discuss how leptogenesis can explain the observed baryon asymmetry and summarize attempts of testing leptogenesis. We first perform estimates and discuss the main physics, and later outline the techniques that allow to perform precise computations.
متن کاملLeptogenesis via Axion Oscillations after Inflation.
Once a light axionlike scalar field couples to the electroweak gauge bosons, its classical motion during reheating induces an effective chemical potential for the fermion number. In the presence of rapid lepton number (L)-violating processes in the plasma, such a chemical potential provides a favorable opportunity for baryogenesis via leptogenesis. We are able to demonstrate that L violation du...
متن کاملCMB constraints on seesaw parameters via leptogenesis
The possibility to explain the CMB measurement of the baryon asymmetry with leptogenesis results in stringent model independent constraints on some of the see-saw parameters. These include the quadratic mean of the light neutrino masses that has to be lower than ∼ 0.17 eV. Furthermore, for maximal CP asymmetry, the observed value of the baryon asymmetry determines a stringent relation for the t...
