Sensitivity of direct detection experiments to neutrino magnetic dipole moments

Understand

With large active volume sizes dark matter direct detection experiments are sensitive to solar neutrino fluxes.

• Nuclear recoil signals are induced by $^8$B neutrinos, while electron recoils are mainly generated by the pp flux.
• Measurements of both processes offer an opportunity to test neutrino properties at low thresholds with fairly low backgrounds.
• In this paper we study the sensitivity of these experiments to neutrino magnetic dipole moments assuming 1, 10 and 40 tonne active volumes (representative of XENON1T, XENONnT and DARWIN), 0.3 keV and 1 keV thresholds.
