Tau decays with one charged particle plus multiple pi(0)'s

Abstract

With the CLEO-II detector at the Cornell Electron Storage Ring, we have measured branching fractions for tau lepton decay into one-prong final states with multiple pi0's, B(hnpi)0, normalized to the branching fraction for tau decay into one charged particle and a single pi0. We find B(h2pi)0/B(hpi)0 = 0.345 +/- 0.006 +/- 0.016, B(h3pi)0/B(hpi)0 = 0.041 +/- 0.003 +/- 0.005, and B(h4pi)0/B(hpi)0 = 0.006 +/- 0.002 +/- 0.002.
