Abstract
We have observed new channels for decays with an in the final state. We study 3-prong tau decays, using the and decay modes and 1-prong decays with two 's using the channel. The measured branching fractions are and . We observe clear evidence for substructure and measure . We have also searched for production and obtain 90% C.L. upper limits and .
