Fermilab scientist Don Lincoln describes the concept of how the search for the Higgs boson is accomplished. The latest data is revealed! Several large experimental groups are hot on the trail of this elusive subatomic particle which is thought to explain the origins of particle mass.

What is all this fuss about the Higgs boson? The physics community is abuzz that a fundamental particle expected by the largely successful Standard Model of particle physics may soon be found by the huge Large Hadron Collider (LHC) at CERN in Europe. The term boson refers to a type of fundamental particle with similarities to the photon, while Higgs refers to Peter Higgs, a physicist who among others published research predicting the mechanism through which such a particle might act. The above animated cartoon explains in humorous but impressive detail why the Higgs boson is expected, and one method that the Large Hadron Collider is using to find it. Although some rumors hint that preliminary traces of the Higgs boson are already being found, even not finding this unusual particle would open the door to a new fundamental understanding of how our universe works.
Professor John Womersley of the Science and Technology Facilities Council takes on the unenviable task of explaining the significance of the findings at Cern.

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, antimatter 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.
Rob Roser, who leads the search for the Higgs boson at the Fermilab in Chicago, said: "Particle physicists have a very high standard for what it takes to be a discovery," and he thinks it is a hair's breadth away. Roser compared the results that scientists will 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."
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.
"It's a real cliffhanger," said Gregorio Bernardi, a physicist at the University of Paris who helped lead one of the main experiments at Fermilab. He cited "strong indications of the production and decay of Higgs bosons" in some of their observations.
