Abstract:

We have observed new channels for τ decays with an η in the final state. We study 3-prong tau decays, using the η → γγ and η → 3π0 decay modes and 1-prong decays with two π0’s using the η → γγ channel. The measured branching fractions are B(τ → π−π−π+ηντ = (3.4+0.6-0.5 ± 0.6) × 10-4 and B(τ− → π−2π0ηντ = (1.4 ± 0.6 ± 0.3) × 10-4. We observe clear evidence for f1 → ηππ substructure and measure B(τ− → f1π−ντ) = (5.8+1.4-1.3 ± 1.8) × 10-4. We have also searched for η′(958) production and obtain 90% C.L. upper limits B(τ → π−η′ντ) < 7.4 × 10-5 and B(τ → π−π0η′ντ) < 8.0 × 10-5. © 1997 American Physical Society.
