Geneva, 18 September 2015. CERN1 Council today announced the election of Professor Sijbrand de Jong as its 22nd President for a period of one year renewable twice, with a mandate starting on 1 January 2016. He will take over from Professor Agnieszka Zalewska who concludes her three-year term at the end of December.
Geneva, 9 September 2015. On Friday, 9 October, CERN1 will be hosting a TEDx conference for the third year running, this time on the theme of “Breaking the Rules”. Providing a platform for visionaries in fields such as science, novel technologies and education, the event, sponsored by Rolex, will take place on the CMS site in Cessy, France.
Geneva/Saint Petersburg, 1st September 2015. Three years after the announcement of the discovery of a new particle, the so-called Higgs boson, the ATLAS and CMS Collaborations present for the first time combined measurements of many of its properties, at the third annual Large Hadron Collider Physics Conference (LHCP 2015). By combining their analyses of the data collected in 2011 and 2012, ATLAS and CMS draw the sharpest picture yet of this novel boson. The new results provide in particular the best precision on its production and decay and on how it interacts with other particles.
Geneva 17 August 2015. The ALICE experiment at the Large Hadron Collider (LHC) at CERN1 has made a precise measurement of the difference between ratios of the mass and electric charge of light nuclei and antinuclei. The result, published today in Nature Physics, conﬁrms a fundamental symmetry of nature to an unprecedented precision for light nuclei. The measurements are based on the ALICE experiment’s abilities to track and identify particles produced in high-energy heavy-ion collisions at the LHC.
Geneva, 12 August 2015. In a paper published today in Nature, the Baryon Antibaryon Symmetry Experiment (BASE1) at CERN2's Antiproton Decelerator (AD), reports the most precise comparison of the charge-to-mass ratio of the proton to that of its antimatter equivalent, the antiproton. The charge-to-mass ratio — an important property of particles — can be measured by observing the oscillation of a particle in a magnetic field. The new result shows no difference between the proton and the antiproton, with a four-fold improvement in the energy resolution compared with previous measurements.
