Available in PDF, EPUB and Kindle. Book excerpt: The branching fraction for B -> rho e nu decays and the CKM matrix element |Vub| is measured with semileptonic exclusive B-meson decays using approximately 55 million Upsilon(4S) -> BBbar decays collected during the years 2000 and 2001 with the BABAR detector. The result is Br(B0 -> rho- e+ nu) = (3.39 +- 0.44 +- 0.52 +- 0.60) x 10^-4, and |Vub| = (3.69 +- 0.23 +- 0.27 +0.40-0.59) x 10^-3. The quoted errors are statistical, systematic, and theoretical respectively. These are combined results obtained using five different form-factor models. Individual results are also quoted.

Available in PDF, EPUB and Kindle. Book excerpt: A preliminary BABAR measurement of the inclusive partial branching fraction b [yields] ue[nu] is presented. The authors find [Delta][Beta](b [yields] ue[nu], 2.3 ... 2.6 GeV) = (0.152 [+-] 0.014[sub stat.] [+-] 0.014[sub syst.]) x 10[sup -3]. In addition, a preliminary measurement of the branching fraction B [yields] [rho]e[nu] is presented and the CKM matrix element V[sub ub] is determined from this measurement. The authors find [Beta](B[sup 0] [yields] [rho][sup -] e[sup +] [nu]) = (3.39 [+-] 0.44[sub stat.] [+-] 0.52[sub syst.] [+-] 0.60 [sub theo].) x 10[sup -4], and V[sub ub] = (3.69 [+-] 0.23[sub stat.] [+-] 0.27[sub syst.] [sub -0.59 theo.][sup +0.40]) x 10[sup -3].

Book excerpt: We present a measurement of the branching fraction for the rare decays B →?e? and extract a value for the magnitude of V{sub ub}, one of the smallest elements of the Cabibbo-Kobayashi-Maskawa quark-mixing matrix. The results are given for five different calculations of form factors used to parametrize the hadronic current in semileptonic decays. Using a sample of 55 million B{bar B} meson pairs recorded with the BABAR detector at the PEP-II ee− storage ring, we obtain?(B° →?−1 e+?) = (3.29 ± 0.42 ± 0.47 ± 0.60) x 10−4 and.

Book excerpt: We report studies of semileptonic decays, B → X{sub c}l[nu], based on a sample of 88 million B{bar B} events recorded with the BABAR detector. We have measured four moments of the electron energy distribution and four moments of the hadronic mass distribution, each as a function of the minimum electron energy. From these moments we determine the inclusive branching fraction, the CKM matrix element.
