Projected sensitivities on sterile neutrino dipole portal with coherent elastic solar neutrino-nucleus scattering

Abstract

Sterile neutrinos can be produced by neutrino beams electromagnetically upscattering on nuclei in the
 presence of a transition magnetic moment between active and sterile neutrinos. We investigate the active
sterile neutrino transition magnetic moment through this upscattering in the coherent elastic neutrino
nucleus scattering (CEνNS) process induced by solar neutrinos. We consider future projection scenarios
 taking into account expected experimental developments at direct detection facilities. We derive projected
 limits on the transition magnetic moment-sterile neutrino mass plane from these scenarios. We compare
 our results with available limits derived from other experiments.
