Search for Rare Particle Decay Comes Up Short

Based on work performed at a large particle detector known as the BaBaR experiment, scientists announced recently that they do not see evidence to support theoretical predictions that an extremely rare particle decay — the decay of the neutral “B” particle into a negative “tau” particle and its antiparticle, the positive tau — occurs often enough to be measured.
