After the discovery of neutrino oscillations, leptogenesis stands as one of the most appealing explanations for the observed baryon asymmetry of the Universe. This framework is usually analyzed in terms of high-energy parameters, not accessible by experiments, and hence it is difficult to extract model-independent conclusions. We present a model-independent formulation of leptogenesis in terms of low energy inputs, and study the interplay between the CP asymmetry of the Universe and the neutrino parameters. We concentrate in particular on the phase delta, that would be measured in neutrino factories, and we discuss the possible implications for leptogenesis of the measurement of this phase."
