Sumario: | One of the most important achievements in the field of particle physics was the discovery of neutrino oscillations. Neutrino oscillation experiments still have a lot to offer, primarily the discovery of CP violation in the lepton sector is anticipated. In addition to solving the remaining puzzles in the standard three-neutrino framework, neutrino experiments are also sensitive to new physics effects that could appear in the process of neutrino production, propagation and/or detection. We discuss a novel class of new physics realizations, testable already at present-day acceleration based experiments such as NOvA and T2K. The idea is based on the fact that neutrino mixing parameters at the scale of neutrino production and neutrino detection do not necessarily need to coincide given that they are subject to renormalization group effects. This mismatch between the leptonic mixing matrix at different scales changes the neutrino oscillation phenomenology by inducing a number of new signatures, some of which are discussed here. |
