### Description

The standard three-neutrino oscillation framework seems to be rather established; however, the percentage level of the precision on the mixing parameters still leaves room for effects not described by the standard physics. Future long baseline (LBL) accelerator experiments will play an important role in the search for new physics effects in neutrino oscillations. Indeed, such experiments will be capable of looking at different oscillation channels and will be able to observe deviation from the standard 3$\nu$ framework at near and far detectors. In our work we explore the performances of the DUNE and T2HKK in constraining different BSM models.

In particular, we study the effects of the possible Non-Unitarity of the PMNS at the detectors of both experiments. We show, for example, how the precision of the $\delta_{CP}$ measurement could be deteriorated if there is any deviation from the unitarity in the mixing matrix.

Furthermore, we explore the performances of DUNE in measuring scalar and vector Non Standard Interactions (NSI) parameters. We investigate different plausible benchmark scenarios in order to determine at what sensitivity level DUNE could differentiate them.
