Abstract: I investigate how the next-to-leading order inclusive one jet cross section changes when the factorization scheme is changed parametrically among a representative sample of schemes.

Abstract: I present a study of the exclusive semi-leptonic B-meson decay anti-B0 -> D*+ l- nu carried out by the CLEO collaboration. I fully reconstruct the D* and charged lepton and determine the angle between the decaying B-meson and the D* - l combination. I present a prelimnary measurement of the branching ratio BR(anti-B0 -> D*+ l- nu) obtained through a fit to the distribution of this angle. This fit separates our signal decay mode from other B decays involving higher D resonance states or additional hadrons in the final state. I discuss the important systematic errors in this analysis, in particular the slow pion tracking efficiency. Finally, I present the technique which will be used to extract the CKM matrix element V_cb with similar methods, and I give the status of that work. This analysis uses a data sample of 3.3 million B-bar B events collected with the CLEO II detector at the Cornell Electron Storage Ring.
