ABSTRACT:
Many precision tests of the Standard Model require input from Lattice QCD (LQCD). Of particular importance are the semileptonic form factors used to extract Vub in semileptonic B decays. Similarities between the D and B sector make charm semileptonic decays an excellent testing ground for the increasingly precise predictions of LQCD. CLEO-c has recently used its entire data sample to produce a set of measurements involving the decays D0 → pi e nu, D0 → K e nu, D+ → pi0 e nu and D+ → K0 e nu. These results, which include the worlds most precise branching fraction and D -> pi form factor measurements, will be discussed.
