Not since the universe was 10 microseconds old have the primary constituents of ordinary matter, quarks and gluons, existed outside the more complex particles, such as protons and neutrons, in which they are irrevocably bundled today. But physicists at CERN, the European particle physics laboratory outside Geneva, recently reported evidence suggesting that they might indeed have created this long-lost state of matter in high-energy collisions of lead nuclei. The possibility has set the physics community abuzz over the past few months, although the hints of quark-gluon plasma are far from definitive.
