Remodeling The Standard Model - Science News
The Large Hadron Collider, the world’s most powerful atom smasher, may be only months away from finding a new elementary particle — a sign of a new force in nature — recent studies suggest.
The studies focus on the top quark, the heaviest of the six quarks, which are the fundamental building blocks of nature. Top quarks appear to behave badly when they are produced during proton-antiproton collisions at a lower-energy particle accelerator, the Fermilab’s Tevatron in Batavia, Ill. Compared with what the standard model of particle physics predicts, these quarks fly off too often in the direction of the proton beam and not enough in the antiproton direction.
