Geneva, 18 December 2015. The 178th session of the CERN Council today saw the handover ceremony from Rolf Heuer, CERN1’s Director-General for the past seven years, to Fabiola Gianotti, who will take up her functions at the head of the Organization on 1 January 2016. On the same day, Sijbrand de Jong will become the new CERN Council President, taking over from Agnieszka Zalewska at the end of her three-year term.
In this section you will find CERN's latest updates and press releases.
CERN and the European Southern Observatory (ESO) have signed a cooperation agreement, providing a framework for future close cooperation and the exchange of information. The agreement addresses many areas, including scientific research, technology, and education and public outreach activities.
The ATLAS and CMS experiments at CERN are taking a very cautionary position concerning a measurement that deviates slightly from what would be expected from known physics. Studying events containing two photons and assuming that these photons originate from the decay of a massive particle, both experiments see a small excess in the mass region of 750-760 GeV. The same analyses were also carried out on the data from the first LHC run and, within the statistics available, did not yield a sizable excess over the expectations from standard physics processes.
Geneva, 25 November 2015. After the successful restart of the Large Hadron Collider and its first months of data taking with proton collisions at a new energy frontier, the LHC is moving to a new phase, with the first lead-ion collisions of season 2 at an energy about twice as high as that of any previous collider experiment. Following a period of intense activity to re-configure the LHC and its chain of accelerators for heavy ion beams, CERN1’s accelerator specialists put the beams into collision for the first time in the early morning of 17 November 2015 and ‘stable beams’ were declared at 10.59am today, marking the start of a one-month run with positively charged lead ions: lead atoms stripped of electrons. The four large LHC experiments will all take data over this campaign, including LHCb, which will record this kind of collision for the first time. Colliding lead ions allows the LHC experiments to study a state of matter that existed shortly after the big bang, reaching a temperature of several trillion degrees.
Geneva, 29 October 2015. This week more than 230 scientists and engineers from around the world met at CERN1 to discuss the High-Luminosity LHC – a major upgrade to the Large Hadron Collider (LHC) that will increase the accelerator’s discovery potential from 2025.
