Today, at the Moriond conference, the ATLAS and CMS collaborations have both presented the observation of a very rare process: the simultaneous production of four top quarks. They were observed using ...
2022年7月9日，在第41届国际高能物理大会（ICHEP2022）上，大型强子对撞机（LHC）实验上的CMS合作组报告了一个可能由四个粲夸克组成的奇特粒子家族的发现。由于这些粒子内部由同一重味夸克组成，物理图像相对简单而利于理解，为我们提供了一个新的窗口研究强相互作用。清华大学和南京师范大学的研究人员联合组成的“清华-南师”CMS组在这项研究中发挥了原创和主导作用。这是中国实验团队首次在LHC上...
