HIGH-ENERGY PHYSICS:
CERN Stakes Claim on New State of Matter
Charles Seife
On Thursday, scientists at CERN, the particle physics laboratory near Geneva, were expected to announce "compelling evidence" of a new state of matter that might be a blazing hot jumble of particles known as a quark-gluon plasma. But many physicists are skeptical. Decisive evidence of such a plasma might appear after a new accelerator known as the Relativistic Heavy Ion Collider, up to five times as powerful as the CERN synchrotron, comes online at Brookhaven National Laboratory in May.
