The LHC can accelerate a beam of protons to 7 trillion electron volts (7 TeV). In 2012, CERN scientists announced their probable discovery of the Higgs boson — the final piece in physicists’ standard model that describes all ordinary matter and the forces acting on it — among the debris created when they collided two such powerful beams.|
