论文摘要

在过去的几十年中，已经出现了许多实验来揭示暗物质的性质，这是现代粒子物理学中讨论最多的开放问题之一。其中，位于实验室Nazionali del Gran Sasso的CRESST实验将闪烁的晶体作为低温声子检测器运行。在这项工作中，我们提出了两个检测器模块的操作，这些模块的运行均具有10.46 g lialo $ _2 $目标。晶体中的锂含量为$^6 $ li，质子和中子有奇数，$^7 $ li，带有奇数的质子。通过考虑锂的同位素和$^{27} $ al，我们将目前最强的横截面上限设置为暗物质与质子和中子的旋转相关性相互作用，以介于0.25至1.5 Gev/c $^2 $之间。

In the past decades, numerous experiments have emerged to unveil the nature of dark matter, one of the most discussed open questions in modern particle physics. Among them, the CRESST experiment, located at the Laboratori Nazionali del Gran Sasso, operates scintillating crystals as cryogenic phonon detectors. In this work, we present first results from the operation of two detector modules which both have 10.46 g LiAlO$_2$ targets in CRESST-III. The lithium contents in the crystal are $^6$Li, with an odd number of protons and neutrons, and $^7$Li, with an odd number of protons. By considering both isotopes of lithium and $^{27}$Al, we set the currently strongest cross section upper limits on spin-dependent interaction of dark matter with protons and neutrons for the mass region between 0.25 and 1.5 GeV/c$^2$.
