"We have enough to get me excited that I'd be willing to bet your house it's real but not enough to bet my house, " said particle physicist Rob Roser of Fermilab, which oversees the Tevatron collider.

WSJ: Physicists Find Signs of Higgs Boson, or 'God Particle'

The U.S.-based scientists outlined their final analysis based on more than 10 years of research and 500 trillion particle collisions using the U.S. Department of Energy's Fermilab Tevatron collider near Batavia, Illinois, whose budgetary woes shut it down last year.

It may be about to happen in particle physics - if neither the Tevatron nor Large Hadron Collider spots a Higgs boson soon, the standard model that scientists have worked with for years may have to be abandoned, or at least seriously reformed, and another built in its place.

For a quarter of a century before CERN's Large Hadron Collider (LHC) began working in earnest in 2009 the Tevatron, at the Fermi National Accelerator Laboratory (Fermilab) in Batavia, near Chicago, dominated high-energy physics.
