Abstract

The DarkSide experiment aims to perform a background-free direct search for dark matter with a dual-phase argon TPC. The current phase of the experiment, DarkSide-50, is acquiring data at Laboratori Nazionali del Gran Sasso and produced the most sensitive limit on the WIMP-nucleon cross section ever obtained with a liquid argon target (2.0 × 10−44 cm2 for a WIMP mass of 100 GeV/c2 ). The future phase of the experiment will be a 20 t fiducial mass detector, designed to reach a sensitivity of ∼ 1 × 10−47 cm2 (at 1 TeV/c2 WIMP mass) with a backgroundfree exposure of 100 ty. This work contains a discussion of the current status of the DarkSide-50 WIMP search and of the results which are more relevant for the construction of the future detector.

lng暗面实验现状与展望

DarkSide实验旨在用双相氩TPC对暗物质进行无背景直接搜索。实验的当前阶段，DarkSide-50，正在格兰萨索国家实验室获取数据，并产生了迄今为止用液态氩气靶获得的WIMP-核子截面最敏感的极限(对于100 GeV/c2的WIMP质量，为2.0 × 10−44 cm2)。实验的未来阶段将是一个20 t基准质量探测器，设计灵敏度为1 × 10−47 cm2(在1 TeV/c2 WIMP质量下)，无背景曝光为100 ty。这项工作包括对darkday -50 WIMP搜索的当前状态的讨论，以及对未来探测器建设更相关的结果。
