We present a measurement of the time-dependent CP-violating (CPV) asymmetries in B0-->K(0)(S)pi(0) decays based on 124x10(6) Upsilon(4S)-->BB decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. In a sample containing 122+/-16 signal decays, we obtain the magnitudes of the direct CPV asymmetry(More)
We present measurements of the branching fraction and CP-violating asymmetries for neutral B decays to D(*+/-)D-/+. The measurement uses a data sample of approximately 88x10(6) Upsilon(4S)-->BBmacr; decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy e(+)-e(-) collider. By fully reconstructing the D(*+/-)D-/+ decay products, we(More)
We present preliminary results from a lepton-tagged fully-inclusive measurement of B → X s γ decays , where X s is any strange hadronic state. Results are based on a BABAR data set of 88.5 million BB pairs at the Υ (4S) resonance. We present a reconstructed photon energy spectrum in the Υ (4S) frame, and partial branching fractions above minimum(More)
A search for the nonconservation of lepton flavor in the decay tau+/--->e+/-gamma has been performed with 2.07x10(8) e+e--->tau+tau- events collected by the BABAR detector at the SLAC PEP II storage ring at a center-of-mass energy near 10.58 GeV. We find no evidence for a signal and set an upper limit on the branching ratio of(More)
We present updated measurements of the CP-violating parameters Spipi and Cpipi in B0-->pi+pi- decays. Using a sample of 227x10(6) Upsilon(4S)-->BB decays collected with the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) collider at SLAC, we observe 467+/-33 signal decays and measure Spipi=-0.30+/-0.17(stat)+/-0.03(syst) and(More)
We present a measurement of time-dependent CP-violating asymmetries in decays of neutral B mesons to the final states D(*-/+)pi(+/-), using approximately 82x10(6) BBmacr; events recorded by the BABAR experiment at the PEP-II e(+)e(-) storage ring. Events containing these decays are selected with a partial reconstruction technique, in which only the(More)
We present a measurement of the total width Γ ηc tot and mass Mη c of the ηc meson with the BABAR detector at the PEP-II B-factory at SLAC. The results based on a data sample of 88 f b −1 are Γ ηc tot = (33.3±2.5(stat.)±0.8(sys.)) MeV/c 2 and Mη c = (2983.3±1.2±1.8) MeV/c 2. An enhancement observed around 3.63 GeV/c 2 can be interpreted as an evidence for(More)
We present measurements of branching fractions and CP-violating asymmetries for two-body neutral B meson decays to charged pions and kaons based on a sample of about 88x10(6) Upsilon(4S)-->BB decays. From a time-independent fit we measure the charge-averaged branching fractions B(B0-->pi+pi-)=(4.7+/-0.6+/-0.2)x10(-6),(More)
A search for the exclusive radiative decays B → ρ(770)γ and B 0 → ω(782)γ is performed on a sample of 84 million BB events collected by the BABAR detector at the P EP − II asymmetric e + e − collider. No significant signal is seen in any of the channels. We set preliminary upper limits of B[B 0 → ρ 0 γ] < 1.4 × 10 −6 , B[B + → ρ + γ] < 2.3 × 10 −6 and B[B 0(More)
