如果实验要充分发挥其潜力，必须精确计算控制中微子双β衰变速率的核矩阵元素。理论学家研究这个问题已经有很长一段时间了，但最近他们加大了努力，因为吨级实验已经开始看起来可行。在这里，我们回顾了过去和最近在各种核模型中关于矩阵元素的工作，并讨论了将在不久的将来完成的工作。从头算核结构理论正在迅速发展，它为更精确的矩阵元素和可量化的误差条提供了希望。
The nuclear matrix elements that govern the rate of neutrinoless double beta decay must be accurately calculated if experiments are to reach their full potential. Theorists have been working on the problem for a long time but have recently stepped up their efforts as ton-scale experiments have begun to look feasible. Here we review past and recent work on the matrix elements in a wide variety of nuclear models and discuss work that will be done in the near future. Ab initio nuclear-structure theory, which is developing rapidly, holds out hope of more accurate matrix elements with quantifiable error bars.
