Results are presented from a search for heavy bottom-like quarks, produced in pairs in pp collisions at √s = 7 TeV, undertaken with the CMS experiment at the LHC. The b′ quarks are assumed to decay exclusively to a top quark and a W boson (tW). The…

A study of dijet production in proton-proton collisions was performed at √s = 7 TeV for jets with pT > 35 GeV and |y| < 4.7[1] using data collected with the CMS detector at the LHC in 2010. Events with at least one pair of jets are denoted as…

Results are presented from a search for new physics in which the final state contains a photon (γ) and missing transverse energy (MET). The data correspond to an integrated luminosity of 5.0 fb−1 (inverse femtobarns) collected in pp collisions at √s…

From the BBC: 'Jim [Al-Khalili] talks [to] CERN physicist, Tejinder Virdee about the search for the elusive Higgs boson, also known as the "God particle". Last December, scientists working at the Large Hadron Collider caught a tantalising glimpse…

The LHC provides CMS with millions of collisions each second, and a wealth of physics data is obtained from the proton-proton interactions. In order to record all these data for analyses, all CMS sub-detectors have to be performing optimally. If you…

On Monday, 12th March 2012, 16 high-school students from Annecy, France awoke with excitement; they knew it was not going to be an ordinary day! Although they live only 40 km away from CERN, the students had never visited the laboratory, and on this…

As a young student, I was taught that mathematics is the language of physics. While largely true, one also cannot communicate in CMS at the CERN LHC without learning a plethora of acronyms. When we wrote the CMS Trigger and Data Acquistion System (…

CMS has presented a rich variety of results at the Electroweak Interactions and Unified Theories sessions of the Rencontres de Moriond conference in La Thuile, Italy. Links to the Physics Analysis Summaries (PAS) from CMS made public in the last…

Please tell us how we can improve the new CMS internal website by clicking on this 1-minute web survey at: https://cern.ch/cms Please don't delay. We'll close the survey at the end of CMS Week and then start implementing missing features. If you…

At a CERN seminar today, CMS presented results for the search for new physics in the decay of Bs and B0 mesons to two muons, taking into account all of the 4.9 fb−1 of data collected in 2011. The results — upper limits of 7.7 x 10−9 (Bs) and 1.8 x…

Google+, the social network by Google, allows users to participate in Hangouts — multi-user video calls. These Hangouts can even be streamed live via a feature called Hangouts On Air. Barack Obama recently used such a Hangout to talk directly to the…
