Description
As neutrino experiments become more precise and explore a wide range of en-
ergies, studying how neutrinos interact with matter has become an important
way to test the Standard Model and search for new physics. In this talk, I will
present our work on neutrino interactions at both low (MeV) and high (GeV)
energy scales. At low energies, we consider coherent elastic neutrino–nucleus
scattering (CE$\nu$NS) at current and upcoming neutrino facilities. CE$\nu$NS allows
to extract key Standard Model parameters like the weak mixing angle and to
explore possible new physics effects such as non-standard neutrino interactions
(NSI), neutrino magnetic moment, and charge radius. At energies relevant for
DUNE, neutrinos interacting with nuclei or electrons can have enhanced cou-
plings to photons if light scalar mediators are present, resulting in a potentially
measurable neutrino polarizability. We identify two possible experimental sig-
natures of such coupling—one or two separated electromagnetic showers with no
associated hadronic activity—and show the projected sensitivity for the DUNE
Near Detector.
