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 (…

Read the paper: SUS-11-003 The analysis shows no excess of events over the Standard Model expectations. As a result, exclusion limits were placed on searches for squarks and gluinos in the Constrained Minimal Supersymmetric extension of the Standard…

It is well known that CERN is an open laboratory, welcoming visitors from around the world on a daily basis. Often these visits are organised by schools or colleges, or are simply part of a family vacation to the Geneva area. Many VIPs also visit,…

The hunt for the Higgs particle is well ahead of schedule, say researchers at the Large Hadron Collider (LHC). Earlier this year they said they would either discover the Higgs or confirm it does not exist by the end of 2012. Now, because the machine…

The latest results from the Large Hadron Collider serve as a reality check for expectations that radical scientific discoveries are just around the corner. A month ago, folks were buzzing about prospects that the elusive Higgs boson might soon be…
