Neutrino charge radii from COHERENT elastic neutrino-nucleus scattering

Abstract

Coherent elastic neutrino-nucleus scattering is a powerful probe of neutrino properties, in particular of the neutrino charge radii. We present the bounds on the neutrino charge radii obtained from the analysis of the data of the COHERENT experiment. We show that the time information of the COHERENT data allows us to restrict the allowed ranges of the neutrino charge radii, especially that of νμ. We also obtained for the first time bounds on the neutrino transition charge radii, which are quantities beyond the standard model.
