Update on the recent progress of the CUORE experiment
摘要：
CUORE是由988 TeO $_2$测辐射热晶体组成的741 kg阵列，旨在寻找$^{130}$ Te的无中微子双β衰变和其他稀有过程。CUORE自2017年夏季以来一直在收集数据，截至2018年夏季，共收集了86.3 kg $\cdot$/年的TeO $_2$暴露量。基于该暴露，我们能够将$^{130}$ Te的$0νββ$半衰期限值设定为90% C. L时的$T^{0ν}_{1/2}>1.5\times10^{25}$年。在这次会议上，我们展示了CUORE背景的分解，并能够提取出$T_{1/2}^{2ν}=[7.9\pm0.1 \mathrm{(stat.)}\pm0.2 \mathrm{(syst.)}]\times10^{20}$年的$^{130}$ Te $2νββ$半衰期。这是该半衰期的最精确测量值，与先前的测量值一致。
英文摘要：
CUORE is a 741 kg array of 988 TeO$_2$ bolometeric crystals designed to search for the neutrinoless double beta decay of $^{130}$Te and other rare processes. CUORE has been taking data since summer 2017, and as of summer 2018 collected a total of 86.3 kg$\cdot$yr of TeO$_2$ exposure. Based on this exposure, we were able to set a limit on the $0νββ$ half-life of $^{130}$Te of $T^{0ν}_{1/2}>1.5\times10^{25}$ yr at 90% C.L. At this conference, we showed the decomposition of the CUORE background and were able to extract a $^{130}$Te $2νββ$ half-life of $T_{1/2}^{2ν}=[7.9\pm0.1 \mathrm{(stat.)}\pm0.2 \mathrm{(syst.)}]\times10^{20}$ yr. This is the most precise measurement of this half-life and is consistent with previous measurements.
