S. Dell'Oro, S. Marcocci, M. Viel, F. Vissani

摘要:

通过观测振荡发现中微子质量,提升了无中微子双β衰变($0νββ$)的重要性。在本文中,我们回顾了这一过程的主要特点,强调其关键作用,从实验和理论的角度来看。特别是,我们将$0νββ$置于轻子数违反过程的全景中,还评估了一些可能的粒子物理机制介导的过程。由于$0νββ$的存在与中微子质量有关,我们还回顾了中微子质量的理论认识的最新进展。在最后一部分中,当前的$0νββ$实验的现状,并为未来寻找$0νββ$的前景进行了讨论。此外,来自宇宙学调查的实验数据被认为是他们对$0νββ$的期望的影响进行检查。

英文摘要:

The discovery of neutrino masses through the observation of oscillations boosted the importance of neutrinoless double beta decay ($0νββ$). In this paper, we review the main features of this process, underlining its key role both from the experimental and theoretical point of view. In particular, we contextualize the $0νββ$ in the panorama of lepton-number violating processes, also assessing some possible particle physics mechanisms mediating the process. Since the $0νββ$ existence is correlated with neutrino masses, we also review the state-of-art of the theoretical understanding of neutrino masses. In the final part, the status of current $0νββ$ experiments is presented and the prospects for the future hunt for $0νββ$ are discussed. Also, experimental data coming from cosmological surveys are considered and their impact on $0νββ$ expectations is examined.
