The July 4th 2012 announcement was widely covered by press. For a small selection of some of the main stories see: Archive of full articles (PDF files in CDS) Archive of screenshots and photos of articles in newspapers, magazines, etc. Below…

I have been a physicist working for CMS for about ten years now, and a guitarist for about twice as long. From time to time I have tried to somehow marry these two worlds, and when I became interested in guitar building I realised that I need to…

Every year CERN opens its doors to hundreds of high-school students who wish to get an in-depth look at what it is like to be a scientist or engineer at one of the world’s most prestigious research laboratories. Sharing their week-long experience…

The Quark Matter 2012 conference, held in Washington DC from 13-18 August 2012, brings together experimental and theoretical experts in the area of heavy-ion physics. This week, the CMS collaboration is presenting many exciting new results using…

CMS has just passed another major milestone, recording more than 10 inverse femtobarns of data at 8 TeV. Despite higher pile-up creating more complicated events, CMS improved its running efficiency and now regularly achieves efficiencies in excess…

31 July 2012, CERN Today CMS submitted for publication, in the Physics Letters B journal, a paper entitled "Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC". The abstract for the paper [get PDF here] reads:…

Version française ci-dessous / French version below The Prime Minister of France Jean-Marc Ayrault visited CERN on the 30th of July, accompanied by the Minister of Higher Education and Research Mme Geneviève Fioraso. The Prime Minister said that he…

Jets are the experimental signatures of quarks and gluons produced in high-energy processes such as head-on proton-proton collisions. As quarks and gluons have a net colour charge and cannot exist freely due to colour-confinement, they are not…

Our understanding of physical reality — of everything and nothing — has changed forever. We don't yet know where we are heading, but nothing will ever be the same. As a scientist, I don't know what more I could ask for. On July 4, two independent…

Signaling a likely end to one of the longest, most expensive searches in the history of science, physicists said Wednesday that they had discovered a new subatomic particle that looks for all the world like the Higgs boson, a key to understanding…

Cern scientists reporting from the Large Hadron Collider (LHC) have claimed the discovery of a new particle consistent with the Higgs boson.

The Higgs boson is a particle associated with the electroweak-symmetry breaking mechanism that was proposed in the 1960s and is a vital component of the Standard Model of particle physics. It is believed that all fundamental particles in the known…
