Scientists whose capture of the 'God particle' hit the headlines three years ago have obtained a new and much sharper picture of their trophy. Data from the Large Hadron Collider (LHC), the world's biggest atom smasher, have greatly increased what physicists know about the Higgs boson, which is responsible for giving other elementary particles mass. The results show with a new level of precision the way the particle is generated and decays, and how it interacts with other particles. CERN's Large Hadron Collider, located in a 27-kilometer (16.8-mile) tunnel beneath the Swiss-French border, was instrumental in the discovery of the Higgs boson. The subatomic particle had long been theorized but wasn't confirmed until 2013.Results show how particle is generated and decaysAlso reveals how it interacts with other particles
