Measurement of the Inclusive Branching Fraction τ-→ντπ-π0+Neutral Meson (s)
Abstract
We measure an inclusive branching fraction of (13.9 ± 2.0-2.2+1.9)% for the decay τ-→ντπ-π0+nh0(n>~1), where h0 is a π0 or an η. The data sample, obtained with the time-projection-chamber detector facility at the SLAC e+e- storage ring PEP, corresponds to an integrated luminosity of 72 pb-1 at 29 GeV center-of-mass energy. The measured branching fraction is somewhat greater than the theoretical prediction and, with errors taken into account, …
