摘要:

无中微子双β($0νββ$)衰变是一种假设的轻子数破坏过程,它提供了唯一已知的方法来断言中微子质量可能的马约拉纳性质。罕见事件低温地下观测站(CUORE)是一个即将进行的实验,旨在使用988 TeO $_2$晶体测辐射热计阵列在10 mK下运行,搜索$^{130}$ Te的$0νββ$衰变。探测器将包含206 kg $^{130}$ Te,平均能量分辨率为5 keV;在$1σ$下,5年寿命后预计的$0νββ$衰变半衰期灵敏度为$1.6\times 10^{26}$ y($9.5\times10^{25}$ y,置信水平为90%),这对应于有效Majorana质量的上限,范围为40- 100 meV(50- 130 meV)。本文综述了CUORE中所使用的实验技术,以及它的现状和预期的物理范围。

英文摘要:

Neutrinoless double-beta ($0νββ$) decay is a hypothesized lepton-number-violating process that offers the only known means of asserting the possible Majorana nature of neutrino mass. The Cryogenic Underground Observatory for Rare Events (CUORE) is an upcoming experiment designed to search for $0νββ$ decay of $^{130}$Te using an array of 988 TeO$_2$ crystal bolometers operated at 10 mK. The detector will contain 206 kg of $^{130}$Te and have an average energy resolution of 5 keV; the projected $0νββ$ decay half-life sensitivity after five years of live time is $1.6\times 10^{26}$ y at $1σ$ ($9.5\times10^{25}$ y at the 90% confidence level), which corresponds to an upper limit on the effective Majorana mass in the range 40--100 meV (50--130 meV). In this paper we review the experimental techniques used in CUORE as well as its current status and anticipated physics reach.
