Description

In this talk, I discuss the possibility to set limits on neutrino electromagnetic properties using the data of the COHERENT experiment and the Dresden-II reactor. I discuss neutrino magnetic moments, charge radii and millicharges. In order to obtain the bounds, the contribution of elastic neutrino-electron scattering, which can become strongly effected for some of the parameters that are considered, must be included, too. I show the dependence of the limits on different hypotheses for the germanium quenching factor and the reactor antineutrino flux. Interestingly, we were able to set a new best upper limit on the electron neutrino charge radius and significantly improve the other CEνNS-related limits on the neutrino electric charge and magnetic moment.
