Abstract: We will discuss how to systematically study physics beyond the standard model (BSM) in neutrino experiments within the Standard Model Effective Field Theory (SMEFT) framework. In this way, the analysis of the data can capture large classes of models, where the new degrees of freedom have masses well above the relevant energy of the experiments. Moreover, it allows us to compare several experiments in a unified framework and in a systematic way. Our proposed approach could be applied to short- and long baseline neutrino experiments. We will show the results of this approach at the FASERv experiment at LHC, the medium baseline reactor experiments Daya Bay and RENO, as well as the projections at the DUNE experiment. For some coupling structures, we find that neutrino experiments will be able to constrain interactions that are almost three orders of magnitude weaker than the Standard Model weak interactions, implying that they will be indirectly probing new physics at the tens of TeV scale.
