Description

In the presence of transition magnetic moments between active and sterile neutrinos, Coherent Elastic Neutrino Nucleus Scattering (CE$\nu$NS) experiments can provide stringent constraints on the neutrino magnetic moment by searching for Primakoff upscattering. I will introduce a new smoking gun signal, a radiative upscattering process with a photon emitted in the final state, which will be able to probe neutrino transition magnetic moments beyond existing limits. Most importantly, I will highlight that such a new experimental mode has the potential to distinguish between the Majorana and Dirac nature of light active neutrinos.
