The recent measurement of the theta_13 angle of the PMNS mixing matrix has opened a new phase in the study of neutrino oscillations.Indeed, as all the three mixing angles are different from zero, the possibility to observe CP violating effects in the leptonic sector becomes the next exciting milestone. This observation would be a very important experimental indication related to the leptogenesis model, our best explanation of the matter-antimatter asymmetry in the universe. This challenging physics goal requires a combination of new accelerator facilities and new large-scale experiments: it can be addressed uniquely by a long-baseline neutrino beam coupled to a large underground neutrino observatory.
