CMS合作组首次发现三J/psi粒子同时产生事件（图）
CMS合作组 三J/psi粒子 奇特强子 “全粲”四夸克态家族
2022/4/22
2021年底，在位于欧洲核子中心（CERN）的大型强子对撞机（LHC）上，物理学家在CMS（Compact Muon Solenoid）实验上首次发现三J/y粒子同时产生事件。2022年4月13日，清华-南师CMS研究组成员、本科生顾晋京代表CMS合作组在美国物理协会四月会议（APSPhysics April Meeting 2022）上报告了这一结果[1]。
The Higgs boson lives for an extremely short time before it transforms, or “decays”, into other particles. It is through the detection of some of these decay products that the unique particle has firs...

The Higgs boson doesn’t stick around for long. Once it is created in particle collisions, the famed particle lives for a mere less than a trillionth of a billionth of a second or, more precisely, 1.6 ...
A triple treat from CMS（图）
CMS 三重款待粒子物理学

It’s a triple treat. By sifting through data from particle collisions at the Large Hadron Collider (LHC), the CMS collaboration has seen not one, not two but three J/ψ particles emerging from a single...
