要旨:
Observation of electrically charged neutrinos is crucial for charge
dequantizaton and for revealing the nature of the neutrino. We analyze new data
of the COHERENT experiment for the coherent neutrino-nucleus scattering to
investigate the electric charges of neutrinos. With almost double the
statistics and precision now, the statistical significance of the observed
process has been enhanced to 11.6$\sigma$. We show how the sensitivity or
limits of the neutrino electric charges depend differently on the interference
effect, inverse power of recoil energy and on the mass of the target particle
than the other electromagnetic properties. We derive constraints all
electromagnetic properties of neutrinos using the new COHERENT data.
