Measurements of the decays tau(-) -> h(-)h(+)h(-)nu(tau) and tau(-) -> h(-)h(+)h(-)pi(0)nu(tau)

We use a data sample of 2.8 × 10 6 produced τ-pair events, obtained with the CLEO II detector, to measure B(τ - Ⅵh - h + h - (π 0 )ν τ ), where h refers to either a charged π or K. These branching fractions are measured with samples of lepton-tagged and 3 vs 3 events. We find B(τ - Ⅵh - h + h - ν τ )=0.0951±0.0007±0.0020 and B(τ - Ⅵh - h + h - π 0 ν τ )=0.0423±0.0006±0.0022. We also measure B(τ - Ⅵωh - ν τ )=0.0195±0.0007±0.0011.

Isospin analysis of D0 decay to three pions

The final state of the decay D 0 → π + π ― π 0 is analyzed in terms of isospin eigenstates. It is shown that the final state is dominated by the isospin-0 component. This suggests that isospin considerations may provide insight into this and perhaps other D 0 -meson decays. We also discuss the isospin nature of the nonresonant contribution in the decay, which can be further understood by studying the decay D 0 → π 0 π 0 π 0 .
