CP Violation and Leptogenesis
The origin of the baryon asymmetry of the Universe is one of the key open questions to be addressed in particle physics and cosmology. Assuming a negligible initial baryon asymmetry, its dynamical production can happen in presence of non-conservation of the baryon and/or lepton number, violation of the C and CP symmetries and out-of-equilibrium conditions. Leptogenesis is a mechanism, proposed ...
متن کاملCP violation and leptogenesis.
Recently a model of chaotic inflation was proposed, where the right handed sneutrinos drive the baryogenesis. We study some of the details of the model, particularly the aspect of CP violation, and determine the number of right handed sneutrinos required for the viability of such models.
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 کاملLeptonic CP Violation and Leptogenesis
We review some recent results on the connection between CP violation at low energies and Leptogenesis in the framework of specific flavour structures for the fundamental leptonic mass matrices with zero textures.

We first study how sterile neutrinos can fit the 5σ ν̄μ → ν̄e LSND anomaly: 2+2 solutions are strongly disfavoured by solar and atmospheric data, while 3+1 solutions can still give a poor fit (for a specific range of oscillation parameters, to be tested by MiniBooNE). If MiniBooNE will see no νμ → νe transitions, we will have a hint for CPT violation. Already now, unlike sterile neutrinos, CPT-vi...
