· Phys. Rev. D; (United States)
A sample of events from the process e/sup +/e/sup -/..-->..tau/sup +/tau/sup -/ observed with the MAC detector operating at the SLAC storage ring PEP is used for a precise measurement of B/sub ..pi../, the branching fraction for the decay tau..--> nu../sub tau/..pi... The result B/sub ..pi../ = 0.107 +- 0.005 +- 0.008 is obtained from a sample of events with 798 identified pions.
