Description
Testing new interactions in the neutrino sector, both in current and upcoming experiments, is essential for uncovering the nature of neutrinos. In many extensions of the Standard Model, active neutrinos may engage in self-interactions via the exchange of new light mediators, often motivated by the need to explain empirical puzzles such as the origin of neutrino mass. Cosmological data also point toward an effective Fermi constant significantly larger than what the Standard Model offers. In this talk, I will show how neutrinophilic mediators can leave indirect yet measurable signatures through radiative corrections to neutrino-matter scattering. I will also discuss the resulting new contributions to the Z-boson decay width and to non-standard neutrino interactions relevant for neutrino oscillation experiments.
