Abstract

In recent years the experimental study of neutrino oscillations has much contributed to our knowledge of particle physics by establishing non vanishing neutrino masses and by measuring or constraining the corresponding mixing angles. Within the domain of neutrino oscillations, the main goal of the next generation of facilities is the measurement of the mixing angle theta13 and the observation of leptonic CP violation, for which we have no hints at the moment. We discuss more in detail how various models of neutrino-nucleus cross section affect the forecasted precision measurement of theta13 and the CP violating phase delta.
