Abstract
From electron-positron collision data collected with the CLEO detector operating at Cornell Electron Storage Ring near roots=10.6 GeV, improved measurements of the branching fractions for tau decays into three explicitly identified hadrons and a neutrino are presented as B(tau(-)-->pi(-)pi(+)pi(-)nu(tau))=(9.13+/-0.05+/-0.46)%, B(tau(-)-->K(-)pi(+)pi(-)nu(tau))=(3.84+/-0.14+/-0.38)x10(-3), B(tau(-)-->K(-)K(+)pi(-)nu(tau))=(1.55+/-0.06+/-0.09)x10(-3), and B(tau(-)-->K(-)K(+)K(-)nu(tau))<3.7x10(-5) at 90% C.L., where the uncertainties are statistical and systematic, respectively.
