Abstract

This contribution reviews several new or updated results on substructure in semi-hadronic tau decays, recently published by the CLEO Collaboration. These results are all based on data collected with the CLEO detector at Cornell's CESR collider, in the reaction $e^+e^-\to \tau^+\tau^-$ at $\sqrt{s} \simeq 10.6$ GeV. Most of these results are based on $\approx 4.3\times 10^6$ $\tau^+\tau^-$ pairs collected with the CLEO II detector between 1990 --- 1995. Some (where noted) also use $\approx 8.0\times 10^6$ $\tau^+\tau^-$ pairs collected with the CLEO II.V detector (which includes a silicon vertex detector and better drift chamber tracking) between 1995 --- 1999.
