26.03.2012: Third CinéGlobe international film festival at CERN to showcase films inspired by science


CERN will be hosting the CinéGlobe international film festival from 27 March to 1 April. This 3rd edition will see 55 short films "inspired by science" in competition, including fictional pieces as well as documentaries. Selected from a long list of 1,400 short films from 107 countries, all the entrants have one thing in common: telling stories inspired by science and technology. The theme of this year's festival is "Infinitely interconnected", casting the spotlight on how interconnected the modern world has become.

The Italian physicist Edoardo Amaldi was CERN's first Secretary General and a driving force for the creation of the laboratory. He was also one of the founding fathers of the European Space Agency (ESA).

On Friday 23 March ESA's third Automated Transfer Vehicle (ATV), named in honour of Amaldi, began its journey to the International Space Station on board an Ariane rocket.

19.03.2012: LHC reaches new threshold of 4 TeV per beam


Physicists in the ATLAS experiment's control room

The Large Hadron Collider reached a new energy threshold of 4 teraelectronvolts (TeV) per beam over the weekend in tests. Increasing the energy at which particles in the LHC collide allows physicists to probe new areas of physics. Collisions at this new energy level are planned for early April.

The LHC is scheduled to run at 4 TeV per beam until late 2012 before going into a long shutdown to prepare for higher energy running. Prior to this the maximum beam energy in the LHC was 3.5 TeV.

At Geneva International Airport today SRB Energy delivered the first of the solar panels that will form one of the largest solar energy systems of Switzerland. Ultimately, some 300 high-temperature solar thermal panels will cover a surface of 1200 square metres on the roof of the airport’s main terminal building. The panels, which will be used to keep the buildings warm during the winter and cool in the summer, are derived from vacuum technology developed at CERN for particle accelerators.

07.03.2012: CERN experiment makes spectroscopic measurement of antihydrogen

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.

05.03.2012: LHCb experiment squeezes the space for expected new physics

Results presented by the LHCb collaboration this evening at the annual ‘Rencontres de Moriond’ conference, held this year in La Thuile, Italy, have put one of the most stringent limits to date on the current theory of particle physics, the Standard Model. LHCb tests the Standard Model by measuring extremely rare processes, in this case a decay pattern predicted to happen just three times out of every billion decays of a particle known as the Bs (B-sub-s) meson. Anything other than that would be evidence for new physics. Measuring the rate of this Bs decay has been a major goal of particle physics experiments in the past decade, with the limit on its decay rate being gradually improved by the CDF and D0 experiments at Fermilab, LHCb, and most recently CMS at CERN.

21.02.2012: The non-LHC experiments in 2012

There is more to CERN than the Large Hadron Collider (LHC). A thousand or so physicists on site research topics from antimatter to astronomy in the non-LHC experiments.

This year the ALPHA, ASACUSA, and ATRAP experiments will compare the properties of antiatoms with their matter counterparts, and AEgIS will try to measure the gravitational constant g using antihydrogen. The CLOUD experiment seeks to understand the influence of cosmic rays on cloud formation, while ACE is researching the use of antiproton beams in cancer therapy.

ISOLDE continues to produce radioisotopes for over 50 experiments, and the nTOF facility provides neutron beams for research fields from astronomy to radioactivity. The CAST and OSQAR experiments are hot on the tail of "axions" and "chameleons", some of the many hypothetical and exotic particles proposed by theorists to explain the nature of dark matter.

These are just a few of the many non-LHC experiments looking forward to a productive 2012 at CERN.

15.02.2012: LHC to run at 4 TeV per beam in 2012

© 2012 CERN

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.

02.02.2012: What to expect from the LHC in 2012

The Large Hadron Collider (LHC), the world's largest particle accelerator, is currently shut down for annual maintenance. In February CERN will decide whether to run the LHC at a total energy of 8 TeV this year, instead of 7 TeV as in 2011. Higher energy should increase the chances of finding heavy particles. By early March, all the magnets around the 27-kilometre accelerator will have been cooled down to their operating temperatures of -271.3°C, ready to guide beams of particles through the LHC.

The LHC will resume colliding protons in late March. The goal is to deliver about 1500 trillion proton-proton collisions (15 inverse femtobarns of data) to the experiments, compared to the 500 trillion collisions delivered in 2011. More collisions will help the LHC experiments to improve the precision of their measurements and push searches for new physics further.

The CMS and ATLAS experiments will continue to look for new particles this year, of which the Higgs boson is the most publicized. Data taken in 2012 will allow them either to confirm a Higgs discovery or to rule out its existence conclusively.

The LHCb experiment will carry on with its precise measurements of quarks, in the search for weak points in the current Standard Model of particle physics. Meanwhile, ALICE is analyzing lead-ion collision data taken in November 2011 in the quest to understand how quark-gluon plasma formed after the Big Bang. More heavy-ion collisions are scheduled for November this year.

Stay tuned for more from CERN in 2012!

The LHC has been in the limelight recently with the first tantalizing hints concerning the Higgs boson. But there's more to physics at the LHC. Two of the LHC experiments have recently made discoveries in other areas of particle physics.

In November the LHCb experiment reported a new effect in the decays of particles containing a charm quark (or antiquark). The result could be the first evidence for CP violation  - a tiny difference in the behaviour of matter and antimatter - in charmed particles. The effect is very small, but more data should reveal whether it points to physics beyond the Standard Model.

In December the ATLAS experiment announced the discovery of a new "quarkonium state", containing a beauty quark bound with its antiquark. Predicted by theory, it is known as the χb(3P). The new state will help in understanding the force that binds quarks (and antiquarks) together.

Watch out for more discoveries in 2012!

12.01.2012: Google launches 2012 science fair


In partnership with CERN, the Google science fair 2012 launches today. Now in its second year, the fair is the world's largest global online science competition for young scientists.

Young people in three age categories (13-14, 15-16, and 17-18) are encouraged to post science projects online for the chance to present them before a panel of acclaimed scientists at Google headquarters, and to win prizes including generous scholarships.

Last year's winning projects included investigations into drug-resistance in cancer cells, carcinogenic compounds in grilled chicken, and effects of environmental pollution on asthma.
