Precise Measurement of τ-Decay Charged-Particle Multiplicity Distribution
Abstract
The charged-particle multiplicity distribution in decays is determined from data collected at the e+e- storage ring PEP. The one-, three-, and five-charged-particle inclusive branching fractions are (86 ± 2)%, (14 ± 2)%, and < 0.5%, respectively. © 1982 The American Physical Society.
