Higgs boson, God particle: CERN scientists say they have proof that long-sought 
particle exists

GENEVA (AP) — Scientists working at the world's biggest atom smasher plan to 
announce Wednesday that they have gathered enough evidence to show that the 
long-sought "God particle" answering fundamental questions about the universe 
almost certainly does exist.

But after decades of work and billions of dollars spent, researchers at the 
European Organization for Nuclear Research, or CERN, say they aren't quite 
ready to say they've "discovered" the particle.

Instead, experts familiar with the research at CERN's vast complex on the 
Swiss-French border say that the massive data they have obtained will 
essentially show the footprint of the key particle known as the Higgs boson — 
all but proving it exists — but doesn't allow them to say it has actually been 
glimpsed.

It appears to be a fine distinction. Senior CERN scientists say that the two 
independent teams of physicists who plan to present their work at CERN's vast 
complex on the Swiss-French border on July 4 are about as close as you can get 
to a discovery without actually calling it one.

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

CERN's atom smasher, the $10 billion Large Hadron Collider, has been creating 
high-energy collisions of protons to help them understand suspected phenomena 
such as dark matter, antimatter and ultimately the creation of the universe 
billions of years ago, which many theorize occurred as a massive explosion 
known as the Big Bang.

For particle physicists, finding the Higgs boson is a key to confirming the 
standard model of physics that explains what gives mass to matter and, by 
extension, how the universe was formed.

Rob Roser, who leads the search for the Higgs boson at the Fermilab in Chicago, 
says "particle physicists have a very high standard for what it takes to be a 
discovery" and thinks it is a hair's breadth away.

Rosen compared the results scientists are preparing to announce Wednesday to 
finding the fossilized imprint of a dinosaur: "You see the footprints and the 
shadow of the object, but you don't actually see it."

Hadron Collider works.
