Parity violating observables in radiative neutrino pair emission from metastable atoms

High Energy Physics - Phenomenology 2014-11-20 v2

Abstract

We report on a possibility of measuring parity violating effects in radiative neutrino pair emission from metastable atoms; asymmetric angular distribution of emitted photons from oriented atoms and emergent circular polarization. Their observation, along with the continuous photon energy spectrum which has 6 thresholds, may be interpreted as events being a combined weak and QED process, emission of γνiνj\gamma \nu_i \nu_j in the final state. The method may greatly help to perform neutrino mass spectroscopy using atoms, a systematic determination of the neutrino mass matrix.
