MoEDAL gets a new detector（图）
MoEDAL实验 大型强子对撞机 探测器 MAPP
2023/5/26
The MoEDAL collaboration at the Large Hadron Collider (LHC) is adding a new detector to its experiment, in time for the start of the next run of the collider this coming summer. Named as the MoEDAL Ap...
The top quark is very special. It’s the heaviest known elementary particle and therefore strongly interacts with the Higgs boson. The top quark’s interactions with other particles provide promising le...
High-energy collisions at the Large Hadron Collider (LHC) allow researchers to clearly study heavy Standard Model particles, like the Higgs boson, that decay almost immediately at the LHC collision po...
CP asymmetry is the only non-trivial difference between matter and antimatter found so far. Its discovery in neutral kaon decays in 1964 came as a big surprise to the physics community, but today it i...
0.8电子伏特！中微子质量上限又有新纪录
德国卡尔斯鲁厄理工学 中微子 粒子物理学 宇宙
2022/2/18
可以说，中微子是宇宙中最神秘的基本粒子。在宇宙学中，它们在大尺度结构的形成中扮演着重要角色；而在粒子物理学中，它们微小但非零的静止质量令它们与众不同，表现出了超出我们当前理论的新的物理现象。如果没有中微子质量尺度的测量，我们对宇宙的理解将会变得不完整。
粒子物理学有了新的基础数学理论
粒子物理学 表示论 基础数学 豪瑟
2022/2/18
近日，来自奥地利和英国的科学家共同发表了一个粒子物理学的基础数学新理论。他们定义和研究了黎曼曲面上存在的非常稳定的希格斯丛，其蕴涵了全局幂零锥稳定分量的多重性的精确表达，以及其与镜像对称性的关系。这个关于希格斯丛的复杂理论有望揭示物理学家长期以来一直试图解决的难题。
The atomic nucleus is a tough nut to crack. The strong interaction between the protons and neutrons that make it up depends on many quantities, and these particles, collectively known as nucleons, are...
Physicists detect a hybrid particle held together by uniquely intense “glue”（图）
混合粒子 电子设备 基本粒子
2023/6/9
In the particle world, sometimes two is better than one. Take, for instance, electron pairs. When two electrons are bound together, they can glide through a material without friction, giving the mater...
In a paper published today in the journal Nature, the BASE collaboration at CERN reports the most precise comparison yet between protons and antiprotons, the antimatter counterparts of protons.
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 ...
ALICE takes the next step in understanding the interaction between hadrons（图）
ALICE 强子 相互作用
2023/5/29
In an article recently published in Physical Review Letters, the ALICE collaboration has used a method known as femtoscopy to study the residual interaction between two-quark and three-quark particles...
Flexible and accessible, the HiRadMat facility celebrates its tenth anniversary（图）
HiRadMat设施 光束冲击 测试材料
2023/5/30
HiRadMat (High-Radiation to Materials) has been a key European facility for material testing for ten years now. It is designed to provide high-intensity, high-momentum pulsed beams to an irradiation a...
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...
Update: The first pilot beams circulated in the LHC on 19 October 2021. On 26 October, there were low-intensity test collisions at an injection energy of 450 GeV per beam and stable collisions of prot...
