Measurement of the Relative Branching Fractions for B- -> D/D*/D**(D(*)pi) l- anti-nu with a Large Sample of Tagged B Mesons

The BABAR Collaboration, B. Aubert

We present a study of B semileptonic decays into charm final states based on 211.7 fb^{-1} of data collected at the Υ(4S) resonance with the babar detector at the pep2 e^+e^- stora…

B Meson Decays to eta(')K*, eta(')rho,eta(')pi0, omegapi0, and phipi0

The BABAR Collaboration, B. Aubert

We present measurements of the branching fractions and charge asymmetries (where appropriate) of two-body B decays to eta(')K*, eta(')rho, eta(')pi0, omegapi0, and phipi0. The data…

Determination of the Branching Fraction for B --> Xc l nu Decays and of |Vcb| from Hadronic-Mass and Lepton-Energy Moments

BABAR Collaboration, B. Aubert, R. Barate +1

We determine the inclusive B --> Xc l nu branching fraction, the CKM matrix element |Vcb|, and other heavy-quark parameters from a simultaneous fit to moments of the hadronic-mass…

Observation of the Decay $B^{\pm} \to π^{\pm} π^{0}$ , Study of $B^{\pm} \to K^{\pm} π^{0}$ , and Search for $B^{0} \to π^{0} π^{0}$

The BABAR Collaboration, B. Aubert

We present results for the branching fractions and charge asymmetries in $B^{\pm} \to h^{\pm} π^{0}$ (where $h^{\pm} = π^{\pm}, K^{\pm}$ ) and a search for the decay $B^{0} \to π^{0…
