标题： Neutrinoless Double Beta Decay Overview

摘要： 无中微子双β衰变是一种假设的核过程，在该过程中两个中子同时衰变为质子且不发射中微子。 这一衰变的珍贵观测将指向一种违反粒子物理标准模型基本对称性的过程，并有助于确定中微子的本质。 目前，这一过程的半衰期下限超过10$^{25}$-10$^{26}$年。 我将回顾双β衰变搜索的现状以及未来几年提高实验灵敏度的前景。 显示英文摘要

摘要： Neutrinoless Double Beta Decay is a hypothesised nuclear process in which two neutrons simultaneously decay into protons with no neutrino emission. The prized observation of this decay would point to the existence of a process that violates a fundamental symmetry of the Standard Model of Particle Physics, and would allow to establish the nature of neutrinos. Today, the lower limits on the half-life of this process exceed 10$^{25}$-10$^{26}$ yr. I will review the current status of the searches for Double Beta Decay and the perspectives to enhance the experimental sensitivity in the next years.
