"Studies of D -> pi e nu and D -> K e nu at CLEO-c"Laura Fields , Cornell University [Host: Craig Dukes]
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 ââ â pi e nu, D0 ââ â K e nu, D+ ââ â pi0 e nu and D+ ââ â K0 e nu. These results, which include the worlds most precise branching fraction and D -> pi form factor measurements, will be discussed.
