摘要:

无中微子双β衰变(0 nubb)是标准模型之外最灵敏的物理探测器之一,提供了关于中微子性质的独特信息。本文综述了测辐射热0 nubb衰变研究的现状和展望。我们总结了最新的进展,背景抑制证明使用测辐射热计同时读出的热和光信号。我们模拟了几种配置的未来CUORE样测辐射热计阵列,将利用这些改进,并提出了一个假设的下一代测辐射热0 nubb实验的灵敏度。我们证明了同位素质量约为1吨的测辐射热实验能够达到10-20 meV量级的Majorana中微子有效质量(|mee|)的灵敏度,从而完全探索了所谓的倒置中微子质量等级区域。我们强调了主要挑战,并确定了解决这些挑战的研发计划的优先事项。

英文摘要:

Neutrinoless double beta decay (0nubb) is one of the most sensitive probes for physics beyond the Standard Model, providing unique information on the nature of neutrinos. In this paper we review the status and outlook for bolometric 0nubb decay searches. We summarize recent advances in background suppression demonstrated using bolometers with simultaneous readout of heat and light signals. We simulate several configurations of a future CUORE-like bolometer array which would utilize these improvements and present the sensitivity reach of a hypothetical next-generation bolometric 0nubb experiment. We demonstrate that a bolometric experiment with the isotope mass of about 1 ton is capable of reaching the sensitivity to the effective Majorana neutrino mass (|mee|) of order 10-20 meV, thus completely exploring the so-called inverted neutrino mass hierarchy region. We highlight the main challenges and identify priorities for an R&D program addressing them.
