We present recent results on charm physics from CLEO-III, emphasizing QCD and hadronic structure. These include the decay Ξ 0 c → pK − K − π + and the form factor for D 0 → π − e + νe. We also discuss upcoming measurements with CLEO-c, including dramatic improvements in the D 0 → π − e + νe form factor, and glueball spectroscopy in J/ψ → γX. The CLEO collaboration has been in existence for over 25 years 1. For the bulk of its history, CLEO has taken data on or near the Υ(4S) resonance, studying B mesons. Charm, produced mainly in the continuum, has also been a strong focus of the CLEO program. This talk outlines two of the most recent results from this ongoing study of charm physics. With the impressive onset of physics results from the B factories Belle and BaBar, CLEO has turned its attention to specifically studying charm in the particularly clean environment encountered at lower energies. This new thrust, including upgrades to the accelerator, is called CLEO-c 2. This talk also discusses how one of our recent charm results will be improved in CLEO-c, as well as a new avenue of investigation into strong (i.e. non-perturbative) QCD, namely production of glueballs in radiative J/ψ decay.
