Fermilab Physicists Don't See Higgs, Argue They Should Keep Looking

摘要

This year's International Conference on High Energy Physics was a case study in irony. The meeting was billed as the coming-out party for the Large Hadron Collider (LHC), the gigantic European atom smasher that started taking data in March, but the buzz surrounded results from the older Tevatron collider at Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois. Quelling rumors, Fermilab physicists said they had not yet spotted a long-sought particle called the Higgs boson. Nevertheless, their improved nonobservation has them pushing to run the Tevatron three extra years, throughrn2014-a plan that officials at Fermilab itself do not necessarily favor.
