Tevatron Teams Clash Over New Physics

By Eugenie Samuel Reich of Nature magazine Research groups at the Tevatron, the proton-antiproton collider at Fermilab in Batavia, Illinois, have reached starkly different conclusions about a possible sighting of new particles beyond what is expected under the standard model of particle physics. In April, researchers on the Collider Detector at Fermilab (CDF) experiment reported tentative evidence that particles not predicted by the standard model had surfaced in collisions that produced a W boson–a particle of the weak nuclear force–and jets of other particles.
