Scientists say ‘God particle’ exists

GENEVA

Physicists say they have all but proven that the “God particle” exists. They have a footprint and a shadow, and the only thing left is to see for themselves the elusive subatomic particle believed to give all matter in the universe size and shape.

Scientists at the world’s biggest atom smasher plan to announce Wednesday that they have nearly confirmed the primary plank of a theory that could restructure the understanding of why matter has mass, which combines with gravity to give an object weight.

The idea is much like gravity and Isaac Newton’s discovery: It was there all the time before Newton explained it. But now scientists know what it is and can put that knowledge to further use.

The focus of the excitement is the Higgs boson, a subatomic particle long sought by physicists.

Researchers at the European Organization for Nuclear Research, or CERN, say that they have compiled vast amounts of data that show the footprint and shadow of the particle, even though it has never actually been glimpsed.

But two independent teams of physicists are cautious after decades of work and billions of dollars spent. They don’t plan to use the word “discovery.” They say they will come as close as possible to a “eureka” announcement without overstating their findings.

“I agree that any reasonable outside observer would say, ‘It looks like a discovery,’” said British theoretical physicist John Ellis, a professor at King’s College London who has worked at CERN since the 1970s. “We’ve discovered something which is consistent with being a Higgs.”

CERN’s atom smasher, the $10 billion Large Hadron Collider on the Swiss-French border, has been creating high-energy collisions of protons to investigate dark matter, anti- matter and the creation of the universe, which many theorize occurred in a massive explosion known as the Big Bang.

The phrase “God particle,” coined by Nobel Prize-winning physicist Leon Lederman, is used by laymen, not physicists, more as an explanation for how the subatomic universe works than how it all started.

Fermilab, whose competing atom smasher reported its final results Monday after shutting down last year, said its data doesn’t settle the question of the Higgs boson, but it came tantalizingly close.
