The discovery of the Higgs boson at CERN’s Large Hadron Collider (LHC) in 2012 marked a significant milestone in particle physics. Since then, the ATLAS and CMS collaborations have been diligently inv...
Where did all the antimatter go? After the Big Bang, matter and antimatter should have been created in equal amounts. Why we live in a Universe of matter, with very little antimatter, remains a myster...
The discovery of the Higgs boson at the Large Hadron Collider (LHC) in 2012 was a triumph of theoretical and experimental physics, yet its implications are only just beginning to be understood. Precis...
Since discovering the Higgs boson 10 years ago, the ATLAS and CMS collaborations have been carrying out numerous measurements of its properties and its interactions with other particles, which have be...
If you asked the average Pennsylvanian why they were celebrating the 4th of July this year, they would probably tell you that it was to mark Independence Day.

Today, exactly ten years after announcing the discovery of the Higgs boson, the international ATLAS and CMS collaborations at the Large Hadron Collider (LHC) report the results of their most comprehen...
Symmetries make the world go round, but so do asymmetries. A case in point is an asymmetry known as charge–parity (CP) asymmetry, which is required to explain why matter vastly outnumbers antimatter i...
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 ...
Zoom into an online particle physics conference, and the chances are you’ll hear the term muon anomaly. This is a longstanding tension with the Standard Model of particle physics, seen in the magnetis...
在7月9日在韩国首尔举行的国际高能物理大会（ICHEP）上，运行在欧洲核子研究中心CERN的大型强子对撞机LHC上ATLAS实验宣布发现Higgs粒子衰变到底夸克对过程。观测到的信号显著性为5.4倍标准偏差，即统计学上该信号是由本底噪声导致的概率小于千万分之一。这是世界上首次观测到的Higgs粒子衰变到底夸克对过程，是2012年发现Higgs粒子以来，LHC实验最重要的物理成果之一。南京大学ATL...
2017年11月30日下午2：00，应物理科学与技术学院（理论物理研究所）武雷教授邀请，上海交通大学何小刚教授来我院讲学。何教授做了题为“Flavor Physics With Higgs and Leptons”的精彩的学术报告。报告由物科院物理学省重点学科带头人肖振军教授主持，理论物理、粒子物理与核物理等相关学科教师及研究生同学约40人参加。何教授从粒子物理的标准模型出发，介绍了这一粒子物理学...
在今年7月5-12日于意大利威尼斯举行的欧洲物理学会高能物理分会（EPS-HEP）上，欧洲核子研究中心大型强子对撞机（LHC）上的ATLAS实验宣布观测到Higgs粒子衰变到底夸克对（Hbb）的过程。结合 2011至2016年共两期质子质子对撞数据， 观测到的信号显著性为 3.6倍标准偏差，即统计学上该信号是本底噪声的概率几乎只是万分之一。这是2012年发现Higgs粒子以来，LHC实验最重要的物...
