British physicist Peter Higgs, (r.), congratulates Fabiola Gianotti, ATLAS experiment spokesperson, after her results presentation during a scientific seminar to deliver the latest update in the search for the Higgs boson at the European Organization for Nuclear Research (CERN) in Meyrin near Geneva, Switzerland, July 4, 2012. The head of the world's biggest atom smasher is claiming discovery of a new particle that he says is consistent with the long-sought Higgs boson known colloquially as the 'God particle' which is believed to give all matter in the universe size and shape.

This image made available by CERN shows a typical candidate event including two high-energy photons whose energy (depicted by red towers) is measured in the CMS electromagnetic calorimeter. The yellow lines are the measured tracks of other particles produced in the collision. The pale blue volume shows the CMS crystal calorimeter barrel. CERN/AP
British physicist Peter Higgs speaks during a press conference on the sideline of his visit to the European Organization for Nuclear Research (CERN) in Geneva, on April 7, 2008. Higgs predicted the existence of an all-pervading force giving mass to the universe and making life possible over 40 years ago.
