对无中微子双β衰变(0νββ)的探索是一种很有前途的实验方法,可以在弱相互作用中寻找轻子数违规,这是通过轻子发生模型产生物质-反物质不对称性的关键因素。基于 136Xe 的 0νββ 实验 KamLAND-Zen 和 EXO-200 目前使用两种截然不同的技术对此过程设定了最严格的限制。每个人都在准备下一代实验,该实验将在与中微子质量倒置层次对应的参数空间中搜索 0νββ。这两种技术都可以很好地扩展到更大的体积,同时融入有趣的新技术。我们介绍了这些合作的当前和下一代实验的状态,并提出了两项​​有可能识别 ββ 衰变事件的进展。
The quest for neutrinoless double-beta decay (0νββ) is a promising experimental approach to search for lepton number violation in weak interactions, a key ingredient in generating the matter-antimatter asymmetry through models of Leptogenesis. The 136Xe-based 0νββ experiments KamLAND-Zen and EXO-200 currently set the most stringent limits on this process using two very different techniques. Each are preparing the next generation experiment, which will search for 0νββ in the parameter space corresponding to the inverted hierarchy for neutrino mass. Both of these techniques scale well to larger volumes while incorporating interesting new techniques. We present the status of current and next generation experiments of these collaborations and present two developments with the potential to identify ββ decay events.
