tau-minus particle
lepton lepton n. (Physics) an elementary particle that participates in weak interactions but does not participate in the strong interaction; it has a baryon number of 0. Some known leptons are the {electron}, the {negative muon}, the {tau-minus particle}, and the neutrinos associated with each of these particles. [WordNet 1.5 +PJC]
