未来中微子质量实验包括无中微子双β衰变的统计分析

Statistical Analysis of future Neutrino Mass Experiments including Neutrino-less Double Beta Decay

Werner Maneschg, Alexander Merle, Werner Rodejohann

摘要:

我们对未来的无中微子双β衰变实验、直接寻找中微子质量(KATRIN)和宇宙学观测的预期结果进行了统计分析。采用了实际误差,并考虑了无中微子双β衰变的核矩阵元不确定性。三个基准方案介绍,对应于准简并,逆层次中微子,和一个中间的情况。我们调查到什么程度,这些场景可以重建。此外,我们检查的兼容性的情况下,声称的证据中微子少双β衰变。

英文摘要:

We perform a statistical analysis with the prospective results of future experiments on neutrino-less double beta decay, direct searches for neutrino mass (KATRIN) and cosmological observations. Realistic errors are used and the nuclear matrix element uncertainty for neutrino-less double beta decay is also taken into account. Three benchmark scenarios are introduced, corresponding to quasi-degenerate, inverse hierarchical neutrinos, and an intermediate case. We investigate to what extend these scenarios can be reconstructed. Furthermore, we check the compatibility of the scenarios with the claimed evidence of neutrino-less double beta decay.
