Probing neutrino magnetic moments at Spallation Neutron Source facilities

Understand

Majorana neutrino electromagnetic properties are studied through neutral current coherent neutrino-nucleus scattering.

• We focus on the potential of the recently planned COHERENT experiment at the Spallation Neutron Source to probe muon-neutrino magnetic moments.
• The resulting sensitivities are determined on the basis of a chi^2 analysis employing realistic nuclear structure calculations in the context of the quasi-particle random phase approximation.
• We find that they can improve existing limits by half an order of magnitude.
