Neutrino experiments, in the next years, aim to determine with precision all
the six parameters of the three-neutrino standard paradigm. The complete success of the
experimental program is, nevertheless, attached to the non-existence (or at least smallness) of
Non-Standard Interactions (NSI). In this work, anticipating the data taken from long-baseline
neutrino experiments, we map all the weakly coupled theories that could induce sizable NSI,
with the potential to be determined in these experiments, in particular DUNE. Once present
constraints from other experiments are taken into account, in particular charged-lepton flavor
violation, we find that only models containing leptoquarks (scalar or vector) and/or neutral
isosinglet vector bosons are viable. We provide the explicit matching formulas connecting
weakly coupled models and NSI, both in propagation and production. Departing from the
weakly coupled completion with masses at TeV scale, we also provide a global fit on all NSI for
DUNE, finding that NSI smaller than 10−2 cannot be probed even in the best-case scenario.
