2023年4月16日上午，国家重点研发计划“大科学装置前沿研究”重点专项“大型强子对撞机上CMS和ALICE实验探测器升级”项目启动会在中国科学院高能物理研究所召开。
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31日至8月6日，第23届国际中微子工厂研讨会（NuFact2022）在美国盐湖城及线上举行，北京大学物理学院高能物理CMS组博士生钱思天（导师为李强研究员）的学术报告“Tests of neutrino mass models at CMS”(在CMS实验中检验中微子质量模型)获得最佳报告奖(Best Presentation Award)。
At CERN’s Large Hadron Collider (LHC), studies of rare processes allow scientists to infer the presence of heavy particles, including undiscovered particles, that cannot be directly produced. Such par...

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...
CMS homes in on Higgs boson’s lifetime（图）
CMS 希格斯玻色子 寿命
2023/5/26
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
2023/5/29
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...
