DARWIN:用稀有液体进行暗物质WIMP研究

DARWIN: dark matter WIMP search with noble liquids

Laura Baudis

摘要:

DARWIN(用惰性液体进行暗物质弱相互作用探测)是欧洲下一代多吨级暗物质探测器的设计研究。液态氩和/或液态氙是直接探测大质量弱相互作用粒子(WIMP)形式的暗物质候选者的目标介质。通过时间投影室技术观察由活性检测器体积中的粒子相互作用产生的光和电荷信号。DARWIN将探测1 e-48 cm 2以下与自旋无关的WIMP-核子截面,并测量具有高统计数据的WIMP诱导核反冲谱,如果它们被现有或不久的将来的实验发现的话。在一个简短的介绍之后,我将描述项目,选择的研发主题,预期的背景和物理范围。

英文摘要:

DARWIN (dark matter wimp search with noble liquids) is a design study for a next-generation, multi-ton dark matter detector in Europe. Liquid argon and/or liquid xenon are the target media for the direct detection of dark matter candidates in the form of weakly interacting massive particles (WIMPs). Light and charge signals created by particle interactions in the active detector volume are observed via the time projection chamber technique. DARWIN is to probe the spin-independent, WIMP-nucleon cross section down 1e-48 cm2 and to measure WIMP-induced nuclear recoil spectra with high-statistics, should they be discovered by an existing or near-future experiment. After a brief introduction, I will describe the project, selected R&D topics, expected backgrounds and the physics reach.
