Our best understanding of how these particles and three of the forces are related to each other is encapsulated in the Standard Model of particle physics. Developed in the early 1970s, it has …

2016年7月6日 · The Standard Model of particle physics is a theory concerning the electromagnetic, weak, and strong nuclear interactions, which mediate the dynamics of the …

2024年9月17日 · At a seminar held at CERN today, the CMS collaboration reported how it has analysed proton–proton collision data from the second run of the Large Hadron Collider, the …

2024年10月11日 · The discovery of the Higgs boson at CERN’s Large Hadron Collider (LHC) in 2012 confirmed the final predicted piece of the Standard Model of particle physics – a powerful …

2024年4月3日 · The Standard Model of Particle Physics is the most precise description to date of particles and their interactions. Precise measurements of its parameters, combined with …

The model describes how everything that they observe in the universe is made from a few basic blocks called fundamental particles, governed by four forces. Physicists at CERN use the …

2023年3月23日 · In its new study, ATLAS reanalysed its 2011 sample of W bosons, improving the precision of its previous measurement. The new W boson mass, 80360 MeV with an …

The Higgs boson can't be “discovered” by finding it somewhere but has to be created in a particle collision. Once created, it transforms – or “decays” – into other particles that can be detected …

Ten years ago, on July 4 2012, the ATLAS and CMS collaborations at the Large Hadron Collider (LHC) announced the discovery of a new particle with features consistent with those of the …

Measuring the properties of the Higgs boson in detail is crucial to exploring many outstanding mysteries in particle physics and cosmology, from the wild variation of masses of elementary …
