Description
In the presence of transition magnetic moments between active and sterile neutrinos, the search for a Primakoff upscattering process at Coherent Elastic Neutrino Nucleus Scattering (CEvNS) experiments provide stringent constraints on the neutrino magnetic moment. We show that a radiative upscattering process with a photon emitted in the final state can provide a novel experimental mode to probe neutrino transition magnetic moments beyond existing limits. Furthermore, the differential distributions for such a radiative mode can also potentially be sensitive to the Dirac vs. Majorana nature of the sterile state mediating the process. This can provide valuable insights into the nature and mass generation mechanism of the light active neutrinos.
