Arts@CERN announces three winning artists and launches an open call

Geneva, 30 April 2015. Arts @ CERN, CERN1's official engagement with the arts, is today announcing three winning art projects from the different strands, Accelerate @ CERN and Collide @ CERN, as well as launching the international open call for Collide @ CERN in digital arts. Now in its fifth year, Arts @ CERN has welcomed more than 70 artists to the Laboratory.

Physics community to discuss latest results of the AMS experiment

Geneva, 15 April 2015. The Alpha Magnetic Spectrometer (AMS1) collaboration will present today the latest results in its quest to understand the origin of cosmic rays and dark matter. These intriguing results will be shared and discussed during the “AMS days” starting today at CERN2, with many of the world’s leading theoretical physicists and principal investigators of some of the major experiments exploring the field of cosmic-ray physics.

Proton beams are back in the LHC

Geneva, 5 April 2015. After two years of intense maintenance and consolidation, and several months of preparation for restart, the Large Hadron Collider, the most powerful particle accelerator in the world, is back in operation. Today at 10.41am, a proton beam was back in the 27-kilometer ring, followed at 12.27pm by a second beam rotating in the opposite direction. These beams circulated at their injection energy of 450 GeV. Over the coming days, operators will check all systems before increasing energy of the beams.

LHC experiments join forces to zoom in on the Higgs boson

Geneva, 17 March 2015. Today during the 50th session of “Rencontres de Moriond” in La Thuile Italy, ATLAS and CMS presented for the first time a combination of their results on the mass of the Higgs boson. The combined mass of the Higgs boson is mH = 125.09 ± 0.24 (0.21 stat. ± 0.11 syst.) GeV, which corresponds to a measurement precision of better than 0.2%. The Higgs boson is an essential ingredient of the Standard Model of particle physics, the theory that describes elementary particles and their interactions.
