摘要
We have measured the branching fractions for the hadronic tau decays, tau --> pi/K n pi(degrees) upsilon (0 less than or equal to n less than or equal to 3), with the L3 detector at LEP. Multiphoton final states are analyzed using the fine-grained, high-resolution electromagnetic calorimeter. The decay channels are identified using a neural network method. The results are: BR(tau --> pi/K upsilon) = (11.82 +/- 0.26 +/- 0.43)%, BR(tau --> pi/K pi(degrees) upsilon) = (25.05 +/- 0.35 +/- 0.50)%, BR(tau --> pi/K2 pi(degrees) upsilon) = (8.88 +/- 0.37 +/- 0.42)%, BR(tau --> pi/K3 pi(degrees) upsilon) = (1.70 +/- 0.24 +/- 0.38)%, where the first error quoted is statistical, the second systematic.
