Title: Charm semi leptonic form factors and Decay Constants fD+ & fDs+

Presenter: Peter Zweber (CLEO), University of Minnesota

Abstract:

Results for the pseudoscalar decay constants fD+ and fDs+, from measurements of D -> mu nu 
and Ds -> mu/tau nu decays, respectively, will be presented.  Semileptonic form factor 
results from D -> (pseudoscalar) l nu and D -> (vector) l nu decays will also presented.  
While the majority of the presented results are from the CLEO Collaboration, results from 
the BES, FOCUS, Belle, and BaBar Collaborations will also be discussed.
