LHC proton run for 2011 reaches successful conclusion

Geneva, 31 October 2011. After some 180 days of running and four hundred trillion (4x1014) proton proton collisions, the LHC’s 2011 proton run came to an end at 5.15pm yesterday evening. For the second year running, the LHC team has largely surpassed its operational objectives, steadily increasing the rate at which the LHC has delivered data to the experiments.

CERN, ESS, and ERF organize the first international workshop on better energy management for Big Science

Lund, 13 October 2011. For the first time, international experts on energy and representatives from large-scale laboratories are getting together to explore new ideas on energy management, identify best practices and implement ways of effective collaboration. This community meets today in Lund, Sweden, at the European Spallation Source (ESS) for a 2-day workshop co-organized by CERN1, ESS and the European Association of National Research Facilities (ERF).

CERN sets course for extra-low-energy antiprotons

Geneva, 28 September 2011. The kick-off meeting for ELENA, the Extra Low Energy Antiproton Ring, starts today at CERN1. Approved by CERN Council in June this year, ELENA is scheduled to deliver its first antiprotons in 2016. This week’s kick-off meeting brings together scientists from Canada, Denmark, France, Germany, Japan, Sweden, the UK and the USA. The project is led by CERN.

Israel to become Associate Member State of CERN

Geneva 16 September 2011. CERN1 Director General Rolf Heuer and Israeli Ambassador and Permanent Representative of Israel to the United Nations Office and other International Organizations in Geneva, H.E. Mr. Aharon Leshno-Yaar today signed a document admitting Israel to CERN Associate Membership, subject to ratification by the Knesset. Following ratification, Israel will become an Associate Member of CERN for a minimum period of 24 months.

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.
