亚稳原子辐射中微子对辐射的宇称破坏观测量

Parity violating observables in radiative neutrino pair emission from metastable atoms

M. Yoshimura, A. Fukumi, N. Sasao, T. Yamaguchi

摘要:

我们报告的可能性测量宇称违反效应的辐射中微子对发射从亚稳原子,从定向原子和出射圆偏振的光子的不对称角分布。它们的观测结果以及具有6个阈值的连续光子能谱可以解释为弱过程和QED过程的结合,即终态发射$γν_i ν_j$。该方法可以极大地帮助使用原子执行中微子质谱,系统地确定中微子质量矩阵。

英文摘要:

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 $γν_i ν_j$ in the final state. The method may greatly help to perform neutrino mass spectroscopy using atoms, a systematic determination of the neutrino mass matrix.
