Leptogenesis and Low-energy Observables
نویسنده
چکیده
We relate leptogenesis in a class of theories to low-energy experimental observables: quark and lepton masses and mixings. With reasonable assumptions motivated by grand unification, one can show that the CP-asymmetry parameter takes a universal form. Furthermore the dilution mass is related to the light neutrino masses. Overall, these models offer a natural explanation for a lepton asymmetry in the early universe. Typeset using REVTEX Electronic address: [email protected] Electronic address: [email protected]

Tests of Leptogenesis at Low Energy
The problem of testing leptogenesis from low energy experiments is discussed following three different perspectives. Firstly, we review the prospects that from low energy experiments we could reconstruct the neutrino Yukawa coupling matrix and hence constrain the leptogenesis mechanism. We emphasize the fact that the experimental determination of the phases and mixings in the light neutrino mas...
متن کاملLepton Flavor Violation and Leptogenesis
A supersymmetric see-saw model obeying the flavor symmetry Lμ−Lτ , which naturally predicts quasi-degenerate neutrinos, is investigated. Breaking of the symmetry is introduced in the Dirac mass matrix because it is the most economic choice in the sense that all interesting low and high energy phenomenology is made possible: we analyze the predictions for the low energy neutrino observables, for...
متن کاملWeak-scale Implications of Thermal Leptogenesis in Susy
Thermal leptogenesis is an attractive mechanism for generating the baryon asymmetry of the Universe. However, in supersymmetric models, the parameter space is severely restricted by the gravitino bound on the reheat temperature TRH . Using a parametrisation of the seesaw in terms of left-handed inputs, which are related to weak-scale observables in mSUGRA, the low-energy footprints of thermal l...
متن کاملLeptogenesis with Single Right-Handed Neutrino Dominance
We make an analytic and numerical study of leptogenesis in the framework of the (Supersymmetric) Standard Model plus the see-saw mechanism with a U(1) family symmetry and single right-handed neutrino dominance. We show that that there is a decoupling between the low energy neutrino observables and the leptogenesis predictions, but that nevertheless leptogenesis is capable of resolving ambiguiti...
متن کاملLeptogenesis and the Violation of Lepton Number and CP at Low Energies
In the context of the minimal supersymmetric seesaw model, we study the implications of the current neutrino data for thermal leptogenesis, ββ0ν decay, and leptonic flavourand CP-violating low-energy observables. We express the heavy singlet-neutrino Dirac Yukawa couplings (Yν)ij and Majorana masses MNi in terms of the light-neutrino observables and an auxiliary hermitian matrix H , which enabl...
