Description
We report an analysis of τ- decaying into ωπ-ντ with ω→π+π-π0 using data containing nearly 320 million tau pairs collected with the BABAR detector at the PEP-II asymmetric energy B-Factory. We find no evidence for second-class currents and set an upper limit at 0.68% at a 90% confidence level for the ratio of second- to first-class currents in this decay mode. The results reported here are preliminary.
