论文摘要
The Majorana nature of neutrinos will be the confirmed by the observation of the rare process called as neutrinoless double beta decay process, i.e. the simultaneous decay of two neutrons in the nucleus of an isotope (A, Z) into two protons and two electrons without the emission of any neutrinos i.e, $(A, Z) \to (A, Z + 2) + 2 e^-$.到目前为止，这种衰变的不观察被解释为对正在研究的同位素的半寿命的下限，这对电子领域中LNV产生的任何新物理产生了严重的限制。另一方面，具有正常排序和倒下的标准机制无法饱和当前的实验限制，而准替代光中微子则因宇宙学数据集中光中微子质量的总和而强烈不利。在这项工作中，我们表明，太阳中微子参数空间的阴暗面以及来自右手电流的新物理贡献的效果如何饱和Kamland-Zen和Gerda提供的实验极限。
The Majorana nature of neutrinos will be the confirmed by the observation of the rare process called as neutrinoless double beta decay process, i.e. the simultaneous decay of two neutrons in the nucleus of an isotope (A, Z) into two protons and two electrons without the emission of any neutrinos i.e, $(A, Z) \to (A, Z + 2) + 2 e^-$. The non-observation of such a decay so far has been interpreted as a lower limit on the half life of the isotope under investigation, which puts severe constraints on any new physics giving rise to LNV in the electron sector. On the other hand, the standard mechanism with normal ordering and inverted ordering can not saturate the present experimental limit while quasi-degenerate light neutrinos are strongly disfavored by the upper limits on the sum of light neutrino masses from cosmological data sets. In this work, we show that how dark side of the solar neutrino parameter space and effect of new physics contributions from right-handed currents can saturate the experimental limit provided by KamLAND-Zen and GERDA.
