Abstract

Using a sample of 4.7 fb integrated luminosity accumulated with the CLEO-II detector at the Cornell Electron Storage Ring (CESR), we have measured the ratios of the branching fractions B(τ →K h π ν )/B(τ →h h h ν )=(5.16±0.20±0.50) × 10 , B(τ →K h π π ν )/B(τ →h h h π ν )=(2.54±0.44±0.39) × 10 , B(τ →K K π ν )/B(τ →h h h ν )=(1.52±0.14 ±0.29) × 10 , and the upper limit B(τ →K K π π ν )/B(τ →h h h π ν )<0.0154 at 95% C.L. Coupled with additional experimental information, we use our results to extract information on the structure of three-prong tau decays to charged kaons. ©1999 The American Physical Society. -1 - - + - - - + - -2 - - + - 0 - - + - 0 -2 - - + - - - + - -2 - - + - 0 - - + - 0 τ τ τ τ τ τ τ τ
