SWITZERLAND-FRANCE-SCIENCE-PHYSICS-PARTICLE-HIGGS

TO GO WITH AFP STORY BY JONATHAN FOWLER A worker stands below the Compact Muon Solenoid (CMS), a general-purpose detector at the European Organisation for Nuclear Research (CERN) Large Hadron Collider (LHC), during maintenance works on July 19, 2013 in Meyrin, near Geneva. Deep below the border between Switzerland and France, the tunnel stretches out of sight, decked with silver installations fit for a starship. A year ago, the world's largest particle collider made one of the greatest discoveries in the history of science, identifying what is believed to be the Higgs Boson -- the long-sought maker of mass. Today, its computer screens are dark, but behind the scenes, work is pushing ahead to give the vast machine a mighty upgrade, enabling it to advance the frontiers of knowledge even farther.
