  Neutrino interactions beyond the Standard Model (BSM) are theoretically well
motivated and have an important impact on the future precision measurement of
neutrino oscillation. In this work, we study the sensitivity of a
multi-ton-scale liquid Xenon dark matter detector equipped with an intense
radiative neutrino source to various BSM neutrino-electron interactions. We
consider the conventional Non-Standard Interactions (NSIs), other more
generalized four-fermion interactions including scalar and tensor forms, and
light-boson mediated interactions. The work shows that with realistic
experimental setups, one can achieve unprecedented sensitivity to these BSM
neutrino-electron interactions.
