这篇讲什么
LUX-ZEPLIN探测器在220天的数据中只留下一个与暗物质相符的粒子相互作用事件,统计显著性仅2.6西格玛,远低于宣称探测所需的5西格玛。研究人员在日本天童举行的TeV粒子天体物理会议上报告了这一结果,认为它可能与高能反冲的弱相互作用大质量粒子或超对称理论预言的希格斯微子有关。LZ已收集到至少三倍于现有分析量的新数据,若真是暗物质,更多事件或许正在等待被发现。
原文开头
One day in June 2023, the numerous, unblinking electronic eyes of the LUX-ZEPLIN detector may have glimpsed something remarkable — possibly the first direct detection of dark matter that pervades the cosmos. Or it may have been just another Friday. A new analysis of data from LUX-ZEPLIN, or LZ, found a single particle interaction that is consistent with dark matter, researchers report at the TeV Particle Astrophysics meeting in Tendo, Japan, and in a paper posted on LZ’s website. But one event is not conclusive. Without more data, scientists can’t be sure what it is. The lone unexpected event has physicists buzzing. …
