recent excitement hint of the higgs
Recent Excitement: Hint of the Higgs

These red lines show how the LHC's Atlas experiment registered the arrival of four particles called muons. They could have been the byproducts of a short-lived Higgs boson--or they could have been more humdrum events. CERN's LHC particle accelerator will continue smashing protons into each other to spot the statistical significance that means the Higgs really has been found. (Credit: CERN)
