As 1996 began, particle physics had been energized by a handful of results that standard theories of particles and forces couldn't readily explain, including a bizarre blip in a detector at the Fermi National Accelerator Laboratory in Illinois and inexplicable decay rates for the fundamental particles called Z bosons at CERN, the European laboratory for particle physics in Geneva. But with new data and analysis, both anomalies have faded. That comes as a disappointment to theorists who had hoped that the mysterious events were the first glimpse of a more encompassing theory of particles and forces known as supersymmetry.
