Description
We consider the effect of general neutrino interactions (scalar, vector,
pseudoscalar, axial vector and tensor) in neutrino-electron scattering
at the DUNE near detector. Those interactions lead to characteristic
deformations of the electron recoil spectrum and can be associated with
heavy new physics. We show that for some cases energy scales up to 9 TeV
are accessible after a 5 year run and that current bounds on interaction
parameters can be improved by up to an order of magnitude. The full set
of general interactions includes the usually considered
neutrino-electron non-standard matter interactions, and the near
detector will give limits comparable but complementary to the ones from
the analysis of neutrino oscillations in the far detector.
