The fourth phase of the CERN openlab partnership to tackle exascale IT challenges for science Geneva, 9 May 2012. The fourth phase of CERN openlab was officially launched during a meeting of its board of sponsors taking place at CERN on 8 and 9 May. CERN openlab is a unique public-private partnership between CERN and leading information technology companies HP, Intel, Oracle, Siemens with contribution from Huawei. Its mission is to accelerate the development of cutting-edge solutions to be used by the worldwide community working on LHC data. The Large Hadron Collider (LHC), the world's largest particle accelerator, generates hundreds of millions of particle collision each second. The record, storage and analysis of these vast amounts of collisions present a massive data challenge: the LHC produces roughly 20 million Gigabytes of data each year. CERN openlab was created more than 10 years ago, to develop innovative, advanced IT systems required to cope with the unprecedented computing challenge of the LHC. It brings together the efforts of science and industry, working at the cutting edge of research to ever expand technological boundaries. The third phase of CERN openlab was officially closed during the meeting of partners. The assembly reviewed key achievements of the projects carried out, and agreed on their very positive impact on the development of the Grid and computing services which underpin the LHC.

CERN experiment makes spectroscopic measurement of antihydrogen Geneva, 7 March 2012. In a paper published online today by the journal Nature, the ALPHA collaboration at CERN* reports an important milestone on the way to measuring the properties of antimatter atoms. This follows news reported in June last year that the collaboration had routinely trapped antihydrogen atoms for long periods of time. ALPHA's latest advance is the next important milestone on the way to being able to make precision comparisons between atoms of ordinary matter and atoms of antimatter, thereby helping to unravel one of the deepest mysteries in particle physics and perhaps understanding why a Universe of matter exists at all. "We've demonstrated that we can probe the internal structure of the antihydrogen atom," said ALPHA collaboration spokesman, Jeffrey Hangst, "and we're very excited about that. We now know that it's possible to design experiments to make detailed measurements of antiatoms." Today, we live in a Universe that appears to be made entirely of matter, yet at the Big Bang, matter and antimatter would have existed in equal amounts. The mystery is that all the antimatter seams to have gone, leading to the conclusion that nature must have a slight preference for matter over antimatter. If antihydrogen atoms can be studied in detail, as ALPHA's latest result suggests, they may provide a powerful tool for investigating this preference. Hydrogen atoms consist of an electron orbiting a nucleus. By firing light at them the atoms can be excited, with the electrons jumping to higher orbits, and eventually relaxing back to their so-called ground state by emitting light. The frequency distribution of the light emitted forms a very precisely measured spectrum that, in the matter world, is unique to hydrogen. Basic principles of physics say that antihydrogen should have an identical spectrum to hydrogen, and measuring this spectrum is the ultimate goal of the ALPHA collaboration. "Hydrogen is the most abundant element in the universe and we understand its structure extremely well," said Hangst. "Now we can finally begin to coax the truth out of antihydrogen. Are they different? We can confidently say that time will tell." In the paper published today, ALPHA reports the first, albeit modest, measurement of the antihydrogen spectrum. In the ALPHA apparatus, antihydrogen atoms are trapped by a sophisticated arrangement of magnetic fields acting on the magnetic orientation of the antihydrogen atoms. By shining microwaves with a precisely tuned frequency on the antihydrogen atoms, the collaboration flips the antiatoms' magnetic orientation, thereby liberating antihydrogen from the trap. When this happens, the antihydrogen meets ordinary matter and annihilates, leaving a characteristic pattern in particle detectors surrounding the trap. This measurement shows that it is possible to set up experiments in which the internal properties of antihydrogen atoms can be changed by shining microwaves on them. In the near future, ALPHA will work at improving the precision of the microwave measurements, and undertake complementary measurements of the antihydrogen spectrum using lasers.

The LHC will run with a beam energy of 4 TeV this year, 0.5 TeV higher than in 2010 and 2011. This decision was taken by CERN management following the annual performance workshop held in Chamonix last week and a report delivered today by the external CERN Machine Advisory Committee (CMAC). It is accompanied by a strategy to optimise LHC running to deliver the maximum possible amount of data in 2012 before the LHC goes into a long shutdown to prepare for higher energy running. The data target for 2012 is 15 inverse femtobarns for ATLAS and CMS, three times higher than in 2011. Bunch spacing in the LHC will remain at 50 nanoseconds.

Higgs search status. In a seminar held at CERN today, the ATLAS and CMS experiments presented the status of their searches for the Standard Model Higgs boson. Their results are based on the analysis of considerably more data than those presented at the summer conferences, sufficient to make significant progress in the search for the Higgs boson, but not enough to make any conclusive statement on the existence or non-existence of the elusive Higgs. The main conclusion is that the Standard Model Higgs boson, if it exists, is most likely to have a mass constrained to the range 116-130 GeV by the ATLAS experiment, and 115-127 GeV by CMS. Tantalising hints have been seen by both experiments in this mass region, but these are not yet strong enough to claim a discovery.

Hundreds of millions of collisions per second -- Detectors collecting data to analyse 24/7 : the LHC and its experiements generate millions of gigabytes of data. The Computing Grid, a huge, worldwide network of computers was invented to manage, process and store these phenomenal volumes of data. How does it work ? Who uses it ? What is its performance since the LHC started up nearly two years ago? What are its other applications outside particle physics ? We're going to review all this with Oliver Keeble, Computing engineer at CERN who works on the computing Grid

Interview of OPERA's spokesperson Antonio Ereditato of the University of Bern and Interview of Dario Autiero CNRS researcher in OPERA experiment Results of the experiment OPERA. The OPERA experiment, which observes a neutrino beam from CERN 730 km away at Italy's INFN Gran Sasso Laboratory, will present new results in a seminar at CERN today. The OPERA result is based on the observation of over 15000 neutrino events measured at Gran Sasso, and appears to indicate that the neutrinos travel at a velocity 20 parts per million above the speed of light, nature's cosmic speed limit. Given the potential far-reaching consequences of such a result, independent measurements are needed before the effect can either be refuted or firmly established. This is why the OPERA collaboration has decided to open the result to broader scrutiny.
