Abstract

The branching fractions for tau --> e nu nu(tau), mu nu nu(tau), and h nu(tau) are measured using data collected with the CLEO detector at the CESR e(+)e(-) collider: beta(mu)=0.1776 +/- 0.0006 +/- 0.0017, beta(mu)=0.1737 +/- 0.0008 +/- 0.0018, and beta(h)=0.1152 +/- 0.0005 +/- 0.0012, where the first error is statistical, the second systematic, and h refers to either a charged pi or K. Also measured is the tau mass, m(tau)=(1778.2 +/- 1.4) MeV. Lepton universality is affirmed by the relative branching fractions (beta(mu)/beta(e)=0.9777 +/- 0.0063 +/- 0.0087, beta(h)/beta(e)=0.6484 +/- 0.0041 +/- 0.0060) and the charged-current gauge coupling-constant ratios (g(mu)/g(e)=1.0026 +/- 0.0055, g(tau)/g(mu)=0.9990 +/- 0.0098). The tau mass result may be recast as atau neutrino mass limit, m(nu tau) < 60 MeV at 95% C.L.
