Description
Long-baseline neutrino experiments are currently measuring the oscillation parameters with unprecedented precision. Recent standard oscillation results from NOvA and T2K, however, show a moderate tension in the preferred value of the CP-violating phase $\delta_{\text{CP}}$, motivating the exploration of physics beyond the standard oscillation framework. Non-Standard Interactions (NSI) in neutrino propagation through matter provide a well-motivated extension of the effective matter potential, altering the neutrino oscillation probabilities. NSI introduce new sources of CP violation and have been proposed as a candidate to alleviate the tension in $\delta_{\text{CP}}$ between NOvA and T2K. Furthermore, the study and constraint of sub-leading new physics effects are necessary to precisely extract the neutrino oscillation parameters. This talk presents recent NSI results from NOvA and their impact on the determination of $\delta_{\text{CP}}$ and the neutrino mass ordering. Prospects for further NSI searches with long-baseline oscillation experiments, including a joint NOvA-T2K NSI fit, as well as with the future flagship DUNE experiment, are also discussed.
