CERN announces the Collide@CERN artists' residency programme

Geneva, 2 September 2011. A new kind of collision will soon be taking place at CERN1’s Geneva laboratory. The Collide@CERN artists’ residency programme means that, as well as colliding particles, CERN will be bringing scientific and artistic creativity into contact. The programme was announced today at the Ars Electronica festival in Linz, Austria.

CERN's LHCb experiment takes precision physics to a new level

Geneva, 26 August 2011. Results to be presented by CERN1’s LHCb experiment at the biennial Lepton-Photon conference in Mumbai, India on Saturday 27 August are becoming the most precise yet on particles called B mesons, which provide a way to investigate matter-antimatter asymmetry. The LHCb experiment studies this phenomenon by observing the way B mesons decay into other particles.

CERN’s CLOUD experiment provides unprecedented insight into cloud formation

Geneva, 25 August 2011. In a paper published in the journal Nature today, the CLOUD1 experiment at CERN2 has reported its first results. The CLOUD experiment has been designed to study the effect of cosmic rays on the formation of atmospheric aerosols - tiny liquid or solid particles suspended in the atmosphere - under controlled laboratory conditions. Atmospheric aerosols are thought to be responsible for a large fraction of the seeds that form cloud droplets. Understanding the process of aerosol formation is therefore important for understanding the climate.

LHC experiments present latest results at Mumbai conference

Geneva, 22 August 2011. Results from the ATLAS and CMS collaborations, presented at the biennial Lepton-Photon conference in Mumbai, India today, show that the elusive Higgs particle, if it exists, is running out of places to hide. Proving or disproving the existence the Higgs boson, which was postulated in the 1960s as part of a mechanism that would confer mass on fundamental particles, is among the main goals of the LHC scientific programme. ATLAS and CMS have excluded the existence of a Higgs over most of the mass region 145 to 466 GeV with 95 percent certainty.
