| dc.description | We report on studies of three types of B-meson decay that can contribute to an understanding of fundamental intergenerational quark mixing, charge-conjugation--parity violation, and long-distance quantum chromodynamics. Specifically, we discuss a selection of analyses related to the Cabibbo-Kobayashi-Maskawa (CKM) parameters Vcb, Vub, alpha, and gamma, and the nonperturbative heavy quark effective theory quantities lambda_1 and lambda_bar. We first describe an examination of the first and second moments of the hadronic-recoil mass and charged-lepton energy spectra in inclusive b -> c l nu decays. We also report on the reconstruction, using similar experimental techniques, of the CKM-suppressed decay B -> rho l nu and the extraction of its branching fraction, Br(B0 -> rho- l+ nu) = (2.57 +- 0.29 +0.33/-0.46 +- 0.41) x 10E-4, as well as the value |Vub| = (3.25 +- 0.14 +0.21/-0.29 +- 0.55) x 10E-3, where the uncertainties are statistical, systematic, and due to model dependence, respectively. Finally, we present results on rare two-body charmless hadronic B -> K pi, pi pi, and K K decays and comment briefly on their implications to the geometry of the CKM unitarity triangle, including a bound on gamma. | |
