Universality and Lepton Flavor Violation in ϒ Decays at CLEO

I present two analyses done with the CLEOIII detector at CESR. The first is a search for the LFV decay ϒ→μτ with preliminary results, and the second constrains Lepton Universality in ϒ→ττ relative to ϒ→μμ. This second analysis, whose results are final, has dramatically improved uncertainties relative to other such measurements, and is also the first observation of the decay ϒ(3S)→ττ. A limit is also set on the involvement of a CP odd Higgs in the decay of the ϒ(1S) to τ pairs.
