Watch the very first TV episode of "What's new @ CERN" featuring CMS physicist Yves Sirois, John Ellis and other physicists talking about the Higgs Boson, the Standard Model, Supersymmetry and neutrinos. "What's new @ CERN" is a new monthly outreach…

The LHC has now delivered over 4 inverse femtobarns (fb−1) of data in 2011, of which CMS has collected 3.7 fb−1.

The international physics masterclasses allow high-school students to spend a day at a research institute and analyse real data from high-energy physics experiments. Conducted under the aegis of the International Particle Physics Outreach Group (…

Next short Technical Stop will take place from Monday the 7th to Friday the 11th of November 2011

On the evening of 23rd September CMS welcomed, for the second successive year, young local students to point 5 for an experience they will never forget - and this time we joined forces with TOTEM. As part of the European Researchers' Night, around…

Read the paper: EXO-11-005 In this Letter, CMS describes a search for a kind of fourth-generation T quark with charge 2/3. The search for T-antiT pairs was performed in events that had a pair of oppositely charged leptons (l+l−) as well as an…

Once upon a time, the only thing that traveled faster than the speed of light was gossip. Thanks to the Internet, the whole physics world was watching on Friday when Dario Autiero, of the Institut de Physique Nucléaire de Lyon in France, in front of…

Have a look at the new FAQ concerning helmet (hard hat):

Over the course of 16.5 hours ending Wednesday, Sept. 14, the CMS experiment recorded 113.4 inverse picobarns of data, more than three times the 36 inverse picobarns it recorded in all of 2010. The detector's data-taking efficiency was impressively…

CERN was a special guest this year at the famous Ars Electronica festival in Linz, Austria. The theme of this year’s festival 'Origin — how it all begins' relates to the diverse research carried out at CERN. Arts@CERN will collaborate with the…

A reminder on CERN Safety rules

The Top quark is the heaviest of the six quarks of the Standard Model and was discovered only 16 years ago by the Tevatron experiments at Fermilab. In addition to the usual production of Top-AntiTop pairs in accordance with quantum chromodynamics (…
