Researchers at CERN (European Center for Nuclear Research) have reason to believe that they have finally observed the elusive superheavy Z0 nuclear particle. The observation is important because it represents the unifying link between the physics of weak-field phenomena and electromagnetic forces. The Z0 particle was predicted by the Salam-Weinberg model, which is an attempt to pull together all physical forces into a single field theory. The as yet uncalibrated experiments at CERN project the new particle's mass at 95±5 GeV, or about the equivalent to the combined masses of 95 protons. What remains in the search for such nuclear particles are “heavier Z0” particles (200 GeV), “top quarks,” and “Higgs particles,” all of which are parts of the Salam-Weinberg model.
