Using DUNE to Shed Light on the Electromagnetic Properties of Neutrinos

Understand

We study future DUNE sensitivity to various electromagnetic couplings of neutrinos, including magnetic moments, milli-charges, and charge radii.

• The DUNE PRISM capabilities play a crucial role in constraining the electron flavored couplings.
• We find that DUNE will be able to place the strongest terrestrial constraint on the muon-neutrino magnetic moment by improving on LSND's bounds by roughly a factor of two, although Borexino's solar constraint will still be stronger.
• For the muon neutrino milli-charge DUNE can place the leading experimental bound, with two orders of magnitude improvement compared to the existing COHERENT constraint.
