The CMS Gas Electron Multiplier (GEM) subsystem will form an extra layer of detectors, along with the Cathode Strip Chambers (CSC) layers, closest to the beam. The GEM's ability to cope with a very high particle rate will greatly improve muon…

On Saturday at 8.25am the shift crew in the CERN Control Centre extracted the beams from the Large Hadron Collider (LHC), bringing the machine’s first three-year running period to a successful conclusion. The following message marked the event on…

The Year-End Technical Stop or YETS, when the LHC takes its annual break, seemed like a quiet time to those outside CERN. After all, there were no collisions taking place and the CMS detector was not operating 24-hours-a-day, seven-days-a-week.…

A new year with new energy and new luminosities: 2012 holds the promise to close the question on the existence (or absence) of a Standard Model Higgs boson. Besides the obvious challenges posed by the LHC restart at a higher energy and a much…

The Large Hadron Collider has woken from its winter slumber with a bang. Just after midnight local time on 5 April, the world's most powerful particle accelerator, based near Geneva, Switzerland, shattered its own world record by smashing protons…

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…

Today, operators of the world’s most powerful particle accelerator announced their plan for the 2012 run. The new schedule calls for the Large Hadron Collider (LHC), located near Geneva, Switzerland, to run at a collision energy of 8 tera-electron…

At about half-past five in the evening on Sunday, 30th October, an e-mail from Run Coordination to the CMS collaboration said: At 17:00 today the LHC dumped the last proton beams for the year to start the machine development period and to prepare…

A few years ago, celebrated British physicist Stephen Hawking was widely reported in the press to have placed a provocative public bet that the LHC (along with all particle accelerators that preceded it) would never find the Higgs boson, the so-…
