希格斯粒子在描述微观世界的“标准模型”中有着举足轻重的地位，基本粒子与希格斯场发生相互作用而获得质量。历时近半个世纪，该粒子于2012年由欧洲核子中心大型强子对撞机上的ATLAS与CMS实验发现，并直接促成2013年的诺贝尔物理学奖。后发现时代的研究重心是继续深入开展希格斯粒子性质测量以期揭示希格斯粒子更深层次的自然本性。ATLAS合作组于希格斯粒子发现十周年纪念日（2022.7.4）将该粒子的最...

在1960年代，物理学家Gell-Mann和Zweig独立提出了被称为夸克的亚原子粒子的存在。他们的模型成功地将拥有强相互作用的粒子 — 强子 — 描述为由两个或三个夸克组成。同时，理论家还预言了存在超过三个夸克的奇异强子，其性质与描述常规强子的夸克模型不同。
