Abstract: We report a Dalitz-plot analysis of the charmless hadronic decays of neutral B mesons to K±ππ0. With a sample of (231.8±2.6) ×106Υ(4S)→BB̄ decays collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC, we measure the magnitudes and phases of the intermediate resonant and nonresonant amplitudes for B0 and B̄0 decays and determine the corresponding CP-averaged branching fractions and charge asymmetries. The inclusive branching fraction and CP-violating charge asymmetry are measured to be B(B0→K+π-π0)=(35.7-1.5+2.6±2.2) ×10-6 and ACP=-0.030-0.051+0.045±0.055 where the first errors are statistical and the second systematic. We observe the decay B0→K* 0(892)π0 with the branching fraction B(B0→K*0(892)π0)=(3.6-0. 8+0.7±0.4)×10-6. This measurement differs from zero by 5.6 standard deviations (including the systematic uncertainties). The selected sample also contains B0→D̄0π0 decays where D̄0→K+π-, and we measure B(B0→D̄0π0)=(2.93±0.17±0.18)×10-4. © 2008 The American Physical Society.

Abstract: Using 383 x 10(6) BBover pairs from the BABAR data sample, we report results for branching fractions of six charged B-meson decay modes, where a charged kaon recoils against a charmless resonance decaying to KKover* or etapipi final states with mass in the range (1.2-1.8) GeV/c2. We observe a significant enhancement at the low KKover* invariant mass which is interpreted as B+-->eta(1475)K+, find evidence for the decay B+-->eta(1295)K+, and place upper limits on the decays B+-->eta(1405)K+, B+-->f1(1285)K+, B+-->f1(1420)K+, and B+-->phi(1680)K+.

Abstract: The τ-→ηπ-π+π-ντ decay with the η→γγ mode is studied using 384fb-1 of data collected by the BABAR detector. The branching fraction is measured to be (1.60±0. 05±0.11)×10-4. It is found that τ-→f1(1285)π- ντ→ηπ-π+π-ντ is the dominant decay mode with a branching fraction of (1.11±0.06±0.05)×10-4. The first error on the branching fractions is statistical and the second systematic. Note that no particle identification algorithm is applied to the charged tracks to distinguish pions from kaons. In addition, a 90% confidence level upper limit on the branching fraction of the τ-→η′(958)π-ντ decay is measured to be 7.2×10-6. This last decay proceeds through a second-class current and is expected to be forbidden in the limit of isospin symmetry. © 2008 The American Physical Society.

Abstract: This paper reports measurements of processes: e+e- →γKS0K±π, e+e-→γK+K-π0, e+e-→γ η, and e+e-→γ π0. The initial-state radiated photon allows to cover the hadronic final state in the energy range from thresholds up to ≈4.6GeV. The overall size of the data sample analyzed is 232fb-1, collected by the BABAR detector running at the PEP-II e+e- storage ring. From the Dalitz plot analysis of the KS0K±π final state, moduli, and relative phase of the isoscalar and the isovector components of the e+e-→KK*(892) cross section are determined. Parameters of and ρ recurrences are also measured, using a global fitting procedure which exploits the interconnection among amplitudes, moduli, and phases of the e+e-→KS0K±π, K+K-π0, η final states. The cross section for the OZI-forbidden process e+e-→ π0, and the J/ψ branching fractions to KK*(892) and K+K-η are also measured. © 2008 The American Physical Society.

Abstract: We report on our search for decays proceeding via a tree-level b-->c quark transition in which a gluon radiates into an ss[over ] pair. We present observations of the decays B;{-}-->D_{s};{+}K;{-}pi;{-} and B[over ];{0}-->D_{s};{+}K_{S};{0}pi;{-} and evidence for B;{-}-->D_{s};{+}K;{-}K;{-} and set upper limits on the branching fractions for B[over ];{0}-->D_{s};{+}K_{S};{0}pi;{-} and B;{-}-->D_{s};{+}K;{-}K;{-} using 383x10;{6} Upsilon(4S)-->BB[over ] events collected by the BABAR detector at SLAC. We present evidence that the invariant mass distributions of D_{s};{+}K;{-} pairs from B;{-}-->D_{s};{+}K;{-}pi;{-} decays are inconsistent with the phase-space model, suggesting the presence of charm resonances lying below the D_{s};{+}K;{-} threshold.

Abstract: We present partial branching fractions for inclusive charmless semileptonic B decays B[over ]-->X_{u}lnu[over ], and the determination of the Cabibbo-Kobayashi-Maskawa matrix element |V_{ub}|. The analysis is based on a sample of 383 x 10;{6} Upsilon(4S) decays into BB[over ] pairs collected with the BABAR detector at the SLAC PEP-II e;{+}e;{-} storage rings. We select events using the invariant mass M_{X} of the hadronic system, the invariant mass squared, q;{2}, of the lepton and neutrino pair, the kinematic variable P+, or one of their combinations. We then determine partial branching fractions in limited regions of phase space: DeltaB=(1.18+/-0.09_{stat}+/-0.07_{syst}+/-0.01_{theor})x10;{-3} (M_{X}8 GeV;{2}/c;{4}). Corresponding values of |V_{ub}| are extracted using several theoretical calculations.

Abstract: We present for the first time a measurement of the weak phase 2β+γ obtained from a time-dependent Dalitz plot analysis of B0→D K0π± decays. Using a sample of approximately 347×106 BB̄ pairs collected by the BABAR detector at the PEP-II asymmetric-energy storage rings and assuming the ratio r of the b→u and b→c decay amplitudes to be 0.3, we obtain 2β+γ=(83±53±20)° and the equivalent solution at +180°. The magnitudes and phases for the resonances associated with the b→c transitions are also extracted from the fit. © 2008 The American Physical Society.

Abstract: We report results of a search for CPT and Lorentz violation in B(0)-B[over ](0) oscillations using inclusive dilepton events from 232 x 10(6) Upsilon(4S)-->BB[over ] decays recorded by the BABAR detector at the PEP-II B Factory at SLAC. We find 2.8sigma significance, compatible with no signal, for variations in the complex CPT violation parameter z at the Earth's sidereal frequency and extract values for the quantities Deltaa(micro) in the general Lorentz-violating standard-model extension. The spectral powers for variations in z over the frequency range 0.26 yr(-1) to 2.1 solar day(-1) are also compatible with no signal.

Abstract: We present a measurement of the branching fraction and photon-energy spectrum for the decay B→Xsγ using data from the BABAR experiment. The data sample corresponds to an integrated luminosity of 210fb-1, from which approximately 680000 BB̄ events are tagged by a fully reconstructed hadronic decay of one of the B mesons. In the decay of the second B meson, an isolated high-energy photon is identified. We measure B(B→Xsγ)=(3. 66±0.85stat±0.60syst)×10-4 for photon energies Eγ above 1.9GeV in the B rest frame. From the measured spectrum we calculate the first and second moments for different minimum photon energies, which are used to extract the heavy-quark parameters mb and μπ2. In addition, measurements of the direct CP asymmetry and isospin asymmetry are presented. © 2008 The American Physical Society.

The results, based on a selected sample of about 52800 B0→D*- +ν decays, recorded by the BABAR detector, are ρ2=1.157±0.094±0.027, R1(1)=1. 327±0.131±0.043, R2(1)=0.859±0.077±0.021, and F(1)|Vcb|=(34.7±0.4±1.0)×10-3. The first error is the statistical and the second is the systematic uncertainty. Combining these measurements with the previous BABAR measurement of the form factors, which employs a different fit technique on a partial sample of the data, we improve the statistical precision of the result, ρ2=1.191±0.048±0.028, R1(1)=1.429±0.061±0.044, R2(1)=0.827±0.038±0.022, and F(1)|Vcb|=(34.4±0.3±1.1)×10-3. Using lattice calculations for the axial form factor F(1), we extract |Vcb|=(37.4±0. 3±1.2±1.41.2)×10-3, where the third error is due to the uncertainty in F(1). We also present a measurement of the exclusive branching fraction, B=(4.69±0.04±0.34)%. © 2008 The American Physical Society.

Abstract: We measure time-integrated CP-violating asymmetries of neutral charmed mesons in the modes D0 --> K(-) K(+) and D0 --> pi(-) pi(+) with the highest precision to date by using D0 --> K(-) pi(+) decays to correct detector asymmetries. An analysis of 385.8 fb(-1) of data collected with the BABAR detector yields values of a(CP)(KK)=(0.00+/-0.34(stat)+/-0.13(syst))% and a(CP)(pipi)=(-0.24+/-0.52(stat)+/-0.22(syst))%, which agree with standard model predictions.

Abstract: We measure the absolute branching fraction for D(0)-->K(-)pi(+) using partial reconstruction of B(0)-->D(*+)Xl(-)nu(l) decays, in which only the charged lepton and the pion from the decay D(*+)-->D(0)pi(+) are used. Based on a data sample of 230 x 10(6) BB pairs collected at the Upsilon(4S) resonance with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC, we obtain B(D(0)-->K(-)pi(+)) = (4.007+/-0.037+/-0.072)%, where the first uncertainty is statistical and the second is systematic.

Abstract: We report measurements of B-meson decays into two- and three-body final states containing two charmed baryons using a sample of 230×106 Υ(4S)→BB̄ decays. We find significant signals in two modes, measuring branching fractions B(B-→Λc+Λ̄c-K-)=(1. 14±0.15±0.17±0.60)×10-3 and B(B- →Ξc0Λ̄c-)×B(Ξc0→Ξ-π+)=(2.08±0. 65±0.29±0.54)×10-5, where the uncertainties are statistical, systematic, and from the branching fraction B(Λc+→pK-π+), respectively. We also set upper limits at the 90% confidence level on two other modes: B(B̄0→Ξc+Λ̄c-)×B(Ξc+→Ξ- π+π+)

Abstract: We present a search for the decay B+→τ+ν using 383×106 BB̄ pairs collected at the Υ(4S) resonance with the BABAR detector at the SLAC PEP-II B Factory. We select a sample of events with one completely reconstructed tag B in a hadronic decay mode (B-→D(*)0X-), and examine the rest of the event to search for a B+→τ+ν decay. We identify the τ lepton in the following modes: τ+→e+νν̄, τ+→μ+νν̄, τ+→π+ν̄, and τ+→π+π0ν̄. We find a 2.2σ excess in data and measure a branching fraction of B(B+→τ+ν)=(1.8-0.8+0.9(stat.) ±0.4(bkg.syst.)±0.2(othersyst.))×10-4.

Abstract: We present a study of excited charm-strange baryon states produced in e+e- annihilations at or near a center-of-mass energy of 10.58 GeV, in a data sample with an integrated luminosity of 384fb-1 recorded with the BABAR detector at the PEP-II e+e- storage rings at the Stanford Linear Accelerator Center. We study strong decays of charm-strange baryons to Λc+KS0, Λc+K-, Λc+K-π+, Λc+KS0π-, Λc+KS0π-π+, and Λc+K-π+π-. This study confirms the existence of the states Ξc(2980)+, Ξc(3077)+, and Ξc(3077)0, with a more accurate determination of the Ξc(2980)+ mass and width. We also present evidence for two new states, Ξc(3055)+ and Ξc(3123)+, decaying through the intermediate- resonant modes Σc(2455)++K- and Σc(2520)++K-, respectively. For each of these baryons, we measure the yield in each final state, determine the statistical significance, and calculate the product of the production cross section and branching fractions. We also measure the masses and widths of these excited charm-strange baryons. © 2008 The American Physical Society.

Abstract: We present measurements of the semileptonic decays B--->D0tau-nutau, B--->D*0tau-nutau, B0-->D+tau-nutau, and B0-->D*+tau-nutau, which are potentially sensitive to non-standard model amplitudes. The data sample comprises 232x10(6) Upsilon(4S)-->BB decays collected with the BABAR detector. From a combined fit to B- and B0 channels, we obtain the branching fractions B(B-->Dtau-nutau)=(0.86+/-0.24+/-0.11+/-0.06)% and B(B-->D*tau-nutau)=(1.62+/-0.31+/-0.10+/-0.05)% (normalized for the B0), where the uncertainties are statistical, systematic, and normalization-mode-related.

Abstract: Using a data sample corresponding to an integrated luminosity of 342 fb(-1) collected with the BABAR detector at the SLAC PEP-II electron-positron storage ring operating at a center-of-mass energy near 10.58 GeV, we measure B(tau(-)--> pi(-)pi(-)pi+nu(tau)(ex.K(S0))=(8.83+/-0.01+/-0.13)%, B(tau(-) -->K(-)pi(-)pi+nu tau(ex.K(S0))=(0.273+/-0.002+/-0.009)%, B(tau(-) -->K(-)pi(-)K+nu tau)=(0.1346+/-0.0010+/-0.0036)%, and B(tau(-) -->K(-)K(-)K+nu tau)=(1.58+/-0.13+/-0.12)x10;{-5}, where the uncertainties are statistical and systematic, respectively. These include significant improvements over previous measurements and a first measurement of B(tau(-) -->K(-)K(-)K+nu tau) in which no resonance structure is assumed. We also report a first measurement of B(tau(-) -->var phi(-)nu tau)=(3.42+/-0.55+/-0.25)x10(-5), a new measurement of B(tau(-) -->var phi K(-)nu tau)=(3.39+/-0.20+/-0.28)x10(-5) and a first upper limit on B(tau(-) -->K(-)K(-)K+nu tau(ex.var phi)).

Abstract: We present a study of resonances in exclusive decays of B mesons to D̄(*)D(*)K. We report the observation of the decays B→D̄(*)Ds1+(2536) where the Ds1+(2536) is reconstructed in the D*0K+ and D*+KS0 decay channels. We report also the observation of the decays B→ψ(3770)K where the ψ(3770) decays to D̄0D0 and D-D+. In addition, we present the observation of an enhancement for the D̄*0D0 invariant mass in the decays B→D̄*0D0K, at a mass of (3875.1-0.5+0.7±0.5)MeV/c2 with a width of (3.0-1.4+1.9±0. 9)MeV (the first errors are statistical and the second are systematic). Branching fractions and spin studies are shown for the three resonances. The results are based on 347fb-1 of data collected with the BABAR detector at the PEP-II B factory. © 2008 The American Physical Society.

Abstract: A search for charmonium and other new states is performed in a study of exclusive initial-state-radiation production of DD̄ events from electron-positron annihilations at a center-of-mass energy of 10.58 GeV. The data sample corresponds to an integrated luminosity of 384fb-1 and was recorded by the BABAR experiment at the PEP-II storage ring. The DD̄ mass spectrum shows clear evidence of the ψ(3770) plus other structures near 3.9, 4.1, and 4.4GeV/c2. No evidence for Y(4260)→DD̄ is observed, leading to an upper limit of B(Y(4260)→DD̄)/B(Y(4260)→J/ψπ+π-)

Abstract: We present an updated measurement of the CP-odd fraction and the time-dependent CP asymmetries in the decay B0→D*+D*- using (383±4)×106BB̄ pairs collected with the BABAR detector. We determine the CP-odd fraction to be 0.143±0.034(stat)±0.008(syst). The time-dependent CP asymmetry parameters are determined to be C+=-0.05±0.14(stat)±0.02(syst) and S+=-0.72±0.19(stat) ±0.05(syst). The nonzero value of the measured S+ indicates the evidence of CP violation at the 3.7σ confidence level. © 2007 The American Physical Society.

Abstract: We report the results of a CP violation analysis of the decay B{+/-}-->D{pi{+}pi{-}pi;{0}}K{+/-}, where D{pi{+}pi{-}pi{0}} indicates a neutral D meson detected in the final state pi{+}pi{-}pi{0}, excluding K{S}{0}pi{0}. The analysis makes use of 324 x 10{6}e{+}e{-}-->BB[over ] events recorded by the BABAR experiment at the PEP-II e;{+}e;{-} storage ring. Analyzing the pi;{+}pi;{-}pi;{0} Dalitz plot distribution and the B{+/-}-->D{pi{+}pi{-}pi{0}}K{+/-} branching fraction and decay rate asymmetry, we find the following one-standard-deviation constraints on the amplitude ratio and on the weak and strong phases: 0.06pi{+}pi{-}pi{0} decay amplitude.

Abstract: We search for decays of a B meson into a neutral D meson and a charged kaon, with the D meson decaying into a charged kaon, a charged pion, and a neutral pion. This final state can be reached through the b→c transition B-→D0K- followed by the doubly Cabibbo-suppressed D0→K+π-π0, or the b→u transition B-→D̄0K- followed by the Cabibbo-favored D̄0→K+π-π0. The interference of these two amplitudes is sensitive to the angle γ of the unitarity triangle. We present results based on 226×106 e+e-→Υ(4S)→BB̄ events collected with the BABAR detector at SLAC. We find no significant evidence for these decays and we set a limit RADS≡Γ([K+π-π0]DK-)+Γ([K-π+π0]DK+) Γ([K+π-π0]DK+)+Γ([K-π+π0]DK-)

Abstract: A search for the neutrinoless, lepton-flavor violating decay of the tau lepton into three charged leptons has been performed using 376 fb{-1} of data collected at an e{+}e{-} center-of-mass energy around 10.58 GeV with the BABAR detector at the SLAC PEP-II storage rings. In all six decay modes considered, the numbers of events found in data are compatible with the background expectations. Upper limits on the branching fractions are set in the range (4-8)x10{-8} at 90% confidence level.

Abstract: We report the results of a CP violation analysis of the decay B{+/-}-->D{pi{+}pi{-}pi;{0}}K{+/-}, where D{pi{+}pi{-}pi{0}} indicates a neutral D meson detected in the final state pi{+}pi{-}pi{0}, excluding K{S}{0}pi{0}. The analysis makes use of 324 x 10{6}e{+}e{-}-->BB[over ] events recorded by the BABAR experiment at the PEP-II e;{+}e;{-} storage ring. Analyzing the pi;{+}pi;{-}pi;{0} Dalitz plot distribution and the B{+/-}-->D{pi{+}pi{-}pi{0}}K{+/-} branching fraction and decay rate asymmetry, we find the following one-standard-deviation constraints on the amplitude ratio and on the weak and strong phases: 0.06pi{+}pi{-}pi{0} decay amplitude.

Abstract: We present the results of searches for decays of B mesons to final states with a b1 meson and a charged pion or kaon. The data, collected with the BABAR detector at the Stanford Linear Accelerator Center, represent 382x10(6) BB[over ] pairs produced in e+e- annihilation. The results for the branching fractions are, in units of 10(-6), B(B+-->b1(0)pi+)=6.7+/-1.7+/-1.0, B(B+-->b1(0)K+)=9.1+/-1.7+/-1.0, B(B0-->b1(-/+)pi(+/-))=10.9+/-1.2+/-0.9, and B(B0-->b1(-)K+)=7.4+/-1.0+/-1.0, with the assumption that B(b1-->omega pi)=1. We also measure charge and flavor asymmetries A(ch)(B+-->b1(0)pi+)=0.05+/-0.16+/-0.02, Ach(B+-->b1(0)K+)=-0.46+/-0.20+/-0.02, A(ch)(B0-->b1(-/+)pi(+/-))=-0.05+/-0.10+/-0.02, C(B0-->b1(-/+)pi(+/-))=-0.22+/-0.23+/-0.05, DeltaC(B0-->b1(-/+)pi(+/-))=-1.04+/-0.23+/-0.08, and A(ch)(B0-->b1(-)K+)=-0.07+/-0.12+/-0.02. The first error quoted is statistical, and the second systematic.

We determine cos2beta=0.42+/-0.49+/-0.09+/-0.13, sin2beta=0.29+/-0.34+/-0.03+/-0.05, and |lambda|=1.01+/-0.08+/-0.02, where the first error is statistical, the second is the experimental systematic uncertainty, and the third, where given, is the Dalitz model uncertainty. Assuming the world average value for sin2beta and |lambda|=1, cos2beta>0 is preferred over cos2beta

Abstract: We present a preliminary study of B- → D 0 (CP)π- and B- → D 0 (CP)K- decays, with the D 0 (CP)reconstructed in the CP-odd eigenstates Ksπ0, Ks, in the CP-even eigenstates K+K-, π+π-, and in the (non-CP) flavor eigenstate K ± π ± . Using a sample of about 382 million γ(4S) decays into BB pairs, collected with the BABAR detector operating at the PEP-II asymmetric-energy B Factory at SLAC, we measure the ratios of the branching fractions B(B- → D 0 CP±K-) + B(B+ → D 0 CP±K+) [B(B- → D 0 K-) + B(B+ → D 0 K+)]/2 and the direct CP asymmetry ACP± Ξ B(B-→D 0 CP±K-) - B(B+→D 0 CP±K+) B(B-→D 0 CP±K-) + B(B+→D 0 CP±K+) . The results are: RCP- = 0.81 ± 0.10(stat) ± 0.05(syst) RCP+ = 1.07 ± 0.10(stat) ± 0.04(syst) ACP- = -0.19 ± 0.12(stat) ± 0.02(syst) ACP+ = 0.35 ± 0.09(stat) ± 0.05(syst).

Abstract: We present preliminary results of a search for B → Xdγ decays with a hadronic mass 1.0 GeV/c2 < M(Xd) < 1.8 GeV/c2. We consider seven final states with up to four charged pions and one neutral pion or η, which correspond to about 50% of the total Xd fragmentation in this mass range. Based on a sample of 383 million B ̄B events collected by the BaBar experiment at PEPII, we measure a partial branching fraction P7 Xd=1 B(B → Xdγ)|(1.0GeV/c2 < M(Xd) < 1.8GeV/c2) = (3.1±0.9+0.6 -0.5 ±0.5) · 10-6, where the uncertainties are statistical, systematic and model-dependent respectively.

Abstract: We perform a time-dependent Dalitz plot analysis of B0 → K0 S π+π- in order to extract the CP violation parameters of f0(980)K0 S and ρ0(770)K0 S and direct CP-asymmetries of Kz.ast;+(892)π-. The results are obtained from a data sample of (383 ± 3) × 106 BB decays, collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. The measured values of 2βeff in B0 decays to f0(980)K0S and ρ0(770)K0 S are (89+22-20 ± 5 ±8) and (37+19 -17 ± 5 ±6), respectively, where the first quoted uncertainty is statistical, the second is systematic and the third is Dalitz plot signal model uncertainty. We measure the significance of 2βeff (f0(980)K0S) 6= 0 to be 4.3 σ. In decays to Kz.ast;(892)π we find ACP = -0.18 ± 0.10 ± 0.03 ± 0.03. The measured phase difference between the decay amplitudes of B0 → Kz.ast;+(892)π- and B0 → Kz.ast;-(892)π+ is (-164 ± 24 ± 12 ± 15). All results are preliminary.

Abstract: We study the decay B 0 → ρ 0 ρ 0 in a sample of about 427 million γ(4S) → BB decays collected with the BABAR detector at the PEP-II asymmetric-energy e + e - collider at SLAC. We find the branching fraction B = (0.84 ± 0.29 ± 0.17) × 10-6 and longitudinal polarization fraction of fL = 0.70 ± 0.14 ± 0.05, where the first uncertainty is statistical, and the second is systematic. The evidence for the B 0 → ρ 0 ρ 0 signal has 3.6σ significance. We investigate the proper-time dependence of the longitudinal component in the decay and measure the CP-violating coefficients S00 L = (0.5± 0.9 ± 0.2) and C00 L = (0.4 ± 0.9 ± 0.2), corresponding to the sine and cosine terms in the time evolution of asymmetry. We study the implication of these results for penguin contributions in B → ρρ decays and for the CKM unitarity angle α.
