Abstract: We present measurements of time-dependent CP-violating asymmetries in neutral B decays to several CP eigenstates. The measurement uses a data sample of 23x10(6) Upsilon(4S)-->BbarB decays collected by the BABAR detector at the PEP-II asymmetric B Factory at SLAC. In this sample, we find events in which one neutral B meson is fully reconstructed in a CP eigenstate containing charmonium and the flavor of the other neutral B meson is determined from its decay products. The amplitude of the CP-violating asymmetry, which in the standard model is proportional to sin2beta, is derived from the decay time distributions in such events. The result is sin2beta = 0.34+/-0.20 (stat)+/-0.05 (syst).

Abstract: We present final measurements of the Z boson-lepton coupling asymmetry parameters Ae, Amu, and Atau with the complete sample of polarized Z bosons collected by the SLD detector at the SLAC Linear Collider. From the left-right production and decay polar angle asymmetries in leptonic Z decays we measure Ae = 0.1544 +- 0.0060, Amu = 0.142 +- 0.015, and Atau = 0.136 +- 0.015. Combined with our left-right asymmetry measured from hadronic decays, we find Ae = 0.1516 +- 0.0021. Assuming lepton universality, we obtain a combined effective weak mixing angle of sin**2 theta^{eff}_W = 0.23098 +- 0.00026., 13 pages latex, including 1 figure. Submitted to Phys. Rev. Lett

Abstract: We have made the first direct symmetry tests in the decays of polarized Z0 bosons into fully identified bbg states, collected in the SLD experiment at SLAC. We searched for evidence of parity violation at the bbg vertex by studying the asymmetries in the b-quark polar- and azimuthal-angle distributions, and for evidence of T-odd, CP-even or CP-odd, final-state interactions by measuring angular correlations between the three-jet plane and the Z0 polarization. We found results consistent with standard model expectations and set 95% C. limits on anomalous contributions.

Abstract: The authors have made the first direct measurement of the parity-violating coupling of the Z{sup 0} boson to the strange quark, A{sub s}, using {approximately}550,000 e{sup +}e{sup {minus}} --> Z{sup 0} --> hadrons event produced with a polarized electron beam and recorded by the SLD experiment. Z{sup 0} s anti-s events were tagged by the absence of B or D hadrons and the presence in each hemisphere of a high-momentum K{sup {+-}} or K{sub s}{sup 0}. From the polar angle distributions of the strangeness-signed thrust axis, the authors obtained A{sub s} = 0.895{+-}0.066(stat.){+-}0.062(syst.). The analyzing power and u anti-u + d anti-d background were constrained using the data.

Abstract: The authors have developed a new technique for inclusive reconstruction of the energy of B hadrons. The excellent efficiency and resolution of this technique allow them to make the most precise determination of the b-quark fragmentation function, using e{sup +}e{sup {minus}} {r{underscore}arrow} Z{sup 0} decays recorded in the SLD experiment at SLAC. The authors compared their measurement with the predictions of a number of fragmentation models. The authors excluded several of these models and measured the average scaled energy of weakly-decaying B hadrons to be (x{sub B}) = 0.714{+-}0.005(stat){+-}0.007(syst){+-}0.002 (model-dependence).

Abstract: The parity violation parameters Ab and Ac of the Zb anti-b and Zc anti-c couplings have been measured directly, using the polar angle dependence of the Z0-pole polarized cross sections. Bottom and charmed hadrons were tagged via semileptonic decays. Both the muon and electron identification algorithms take advantage of new multivariate techniques, incorporating for the first time information from the SLD Cerenkov Ring Imaging Detector. Based on the 1993-95 SLD sample of 150,000 Z0 decays produced with highly polarized electron beams, we measure: Ab = 0.910 ± 0.068(stat) ± 0.037(syst) Ac = 0.642 ± 0.110(stat) ± 0.063(syst).

Abstract: We present a direct measurement of the parity-violating asymmetry A{sub b} in the Z{sup 0} to b anti-b coupling using a new technique to distinguish the b and anti-b quarks using charged kaons from B decays. The Z{sup 0} bosons are produced in e{sup +}e{sup -} collisions at the SLC with longitudinally polarized electrons. b anti-b events are selected using a secondary vertex mass tag and A{sub b} is determined from the left-right forward-backward asymmetry. From the 1994-1995 data sample, selected from 100,000 hadronic Z{sup 0} decays, we obtain A{sub b} = 0.855 {+-} 0. 088{sub stat} {+-} 0.102{sub sys}.

Abstract: We present a direct measurement of the parity-violation parameter ${A}_{b}$ using a self-calibrating track-charge technique. In the SLAC Linear Collider Large Detector (SLD) experiment we observe hadronic decays of ${Z}^{0}$ bosons produced in collisions between longitudinally polarized electrons and unpolarized positrons at the SLAC Linear Collider. A sample of $b\overline{b}$ events is selected using the topologically reconstructed mass of $B$ hadrons. From our 1993--1995 sample of approximately 150 000 hadronic ${Z}^{0}$ decays, we obtain ${A}_{b}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.911\ifmmode\pm\else\textpm\fi{}0.045(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.045(\mathrm{syst})$.

Abstract: During 1996 the SLD collaboration completed the construction of, and began the operation of, a new vertex detector (VXD3). This detector, based on 96 CCD’s each of 13 cm 2 area, is an upgrade of the original vertex detector of SLD (VXD2), and is made possible by advances in the technology of CCD detectors. New front-end electronics and a new data acquisition system were developed for this upgrade. Its improved characteristics will enhance many SLD measurements, and open the possibility to observe B s 0 -mixing. More than 50 000 Z events obtained with the new vertex detector have been analyzed. Results on the new detector performance (including resolution evaluation) from this first data are presented.

Abstract: We report a new measurement of Rb = Gamma(Z0->b-bbar) / Gamma(Z0->hadrons) using a double tag technique, where the b hemisphere selection is based on the reconstructed mass of the B hadron decay vertex. The measurement was performed using a sample of 130k hadronic Z0 events, collected with the SLD at the SLC. The method utilizes the 3-D vertexing abilities of the CCD pixel vertex detector and the small stable SLC beams to obtain a high b-tagging efficiency and purity. We obtain Rb=0.2142+/-0.0034(stat.)+/-0.0015(syst.)+/-0.0002(R_c)., 11 pages including 3 eps files

Abstract: This paper describes the design, construction, and initial operation of SLD's upgraded vertex detector which comprises 96 two-dimensional charge-coupled devices (CCDs) with a total of 307 Mpixel. Each pixel functions as an independent particle detecting element, providing space point measurements of charged particle tracks with a typical precision of 4 μm in each co-ordinate. The CCDs are arranged in three concentric cylinders just outside the beam-pipe which surrounds the e+e− collision point of the SLAC Linear Collider (SLC). The detector is a powerful tool for distinguishing displaced vertex tracks, produced by decay in flight of heavy flavour hadrons or tau leptons, from tracks produced at the primary event vertex. The requirements for this detector include a very low mass structure (to minimize multiple scattering) both for mechanical support and to provide signal paths for the CCDs; operation at low temperature with a high degree of mechanical stability; and high speed CCD readout, signal processing, and data sparsification. The lessons learned in achieving these goals should be useful for the construction of large arrays of CCDs or active pixel devices in the future in a number of areas of science and technology.

Abstract: We have measured the $B$ hadron energy distribution in ${Z}^{0}$ decays using a sample of semileptonic $B$ decays recorded in the SLD experiment at SLAC. The energy of each tagged $B$ hadron was reconstructed using information from the lepton and a partially reconstructed charm-decay vertex. We compared the scaled energy distribution with several models of heavy quark fragmentation. The average scaled energy of primary $B$ hadrons was found to be $〈{x}_{{E}_{B}}〉=0.716\ifmmode\pm\else\textpm\fi{}0.011(\mathrm{stat}{)}_{\ensuremath{-}0.022}^{+0.021}(\mathrm{syst})$.

Abstract: We present a new measurement of the tau neutrino helicity, hnu and the tau Michel parameters rho, eta, xi and the product delta xi. The analysis exploits the highly polarized SLC electron beam to extract these quantities directly from a measurement of the tau decay spectra, using the 1993-1995 SLD data sample of 4328 e+e- --> Z0 --> tau+tau- events. From the decays tau --> pi nu(tau) and tau --> rho nu(tau) we obtain a combined value hnu=-0.93+/-0.10+/-0.04. The leptonic decay channels yield combined values of rho=0.72+/-0.09+/-0.03, xi=1.05+/-0.35+/-0.04 and delta xi=0.88+/-0.27+/-0.04.

Abstract: We present evidence for leading particle production in hadronic decays of the Z{sup 0} boson to light-flavor jets. A polarized electron beam was used to tag quark and antiquark jets, and a vertex detector was employed to reject heavy-flavor events. Charged hadrons were identified with a Cherenkov ring imaging detector. In the quark jets, more high-momentum p, L, K{sup -}, and {bar K}{sup *0} were observed than their antiparticles, and vice versa for antiquark jets, providing direct evidence that the higher-momentum particles in jets are more likely to carry the primary quark or antiquark from the Z{sup 0} decay, and that s{bar s} production is suppressed in fragmentation. {copyright} {ital 1997} {ital The American Physical Society}

Abstract: We present a new measurement of the left-right cross section asymmetry (ALR) for Z boson production by e+e- collisions. The measurement was performed at a center-of-mass energy of 91.28 GeV with the SLD detector at the SLAC Linear Collider (SLC). The luminosity-weighted average polarization of the SLC electron beam was (77.23+-0.52)%. Using a sample of 93,644 Z decays, we measure the pole-value of the asymmetry, ALR0, to be 0.1512+-0.0042(stat.)+-0.0011(syst.) which is equivalent to an effective weak mixing angle of sin**2(theta_eff)=0.23100+-0.00054(stat.)+-0.00014(syst.).

Abstract: We have measured the distributions of the jet energies in {ital e{sup +}e{sup {minus}}{r_arrow}q{bar q}g} events, and of the three orientation angles of the event plane, using hadronic {ital Z{sup 0}} decays collected in the SLD experiment at SLAC. We find that the data are well described by perturbative QCD incorporating vector gluons. We have also studied models of scalar and tensor gluon production and find them to be incompatible with our data. {copyright} {ital 1997} {ital The American Physical Society}

Abstract: The SLD collaboration completed construction of a new CCD vertex detector (VXD3) in January 1996 and started data taking in April 1996 with the new system. VXD3 is an upgrade of the original CCD vertex detector, VXD2, which had successfully operated in SLD for three years. VXD3 consists of 96 large area CCDs, each having 3.2 million 20 μm × 20 μm pixels. By reducing the detector material and lengthening the lever arm, VXD3 is expected to improve secondary vertex resolution by about a factor of two compared with VXD2. The new three-layered structure enables stand-alone tracking without any ambiguity and its extended size along the beam direction improves the polar-angle coverage to |cos θ| < 0.85. An overview of this detector system and its initial performance are described.

Abstract: We present the first measurement of the left-right charge asymmetry ${A}_{Q}^{\mathrm{obs}}$ in hadronic $Z$ boson decays. This was performed at ${E}_{\mathrm{c}.\mathrm{m}.}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}91.27\mathrm{GeV}$ with the SLD at the SLAC Linear Collider with a polarized electron beam. Using 89 838 events we obtain ${A}_{Q}^{\mathrm{obs}}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.225\ifmmode\pm\else\textpm\fi{}0.056\ifmmode\pm\else\textpm\fi{}0.019$, which leads to a measurement of the electron left-right asymmetry parameter, ${A}_{e}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.162\ifmmode\pm\else\textpm\fi{}0.041\ifmmode\pm\else\textpm\fi{}0.014$, and ${sin}^{2}{\ensuremath{\theta}}_{W}^{\mathrm{eff}}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.2297\ifmmode\pm\else\textpm\fi{}0.0052\ifmmode\pm\else\textpm\fi{}0.0018$. Also, the ${A}_{Q}^{\mathrm{obs}}$ measurement combined with the left-right cross section asymmetry determines ${A}_{e}$ independent of the value of the electron-beam polarization.

Abstract: We present the first measurement of the correlation between the {ital Z}{sup 0} spin and the event-plane orientation in polarized {ital Z}{sup 0} decays into three jets in the SLAC Linear Collider Large Detector experiment at SLAC utilizing a longitudinally polarized electron beam. The {ital CP}-even and {ital T}-odd triple product {ital {rvec S}}{sub {ital Z}}{center_dot}({ital {rvec k}}{sub 1}{times}{ital {rvec k}}{sub 2}), formed from the two fastest jet momenta {ital {rvec k}}{sub 1} and {ital {rvec k}}{sub 2} and the {ital Z}{sup 0} polarization vector {ital {rvec S}}{sub {ital Z}}, is sensitive to physics beyond the standard model. We measure the expectation value of this quantity to be consistent with zero and set 95% C.L. limits of {minus}0.022{lt}{beta}{lt}0.039 on the correlation. {copyright} {ital 1995} {ital The} {ital American} {ital Physical} {ital Society}.

Abstract: We have compared a new QCD calculation by Clay and Ellis of energy-energy correlations (EEC`s) and their asymmetry (AEEC`s) in {ital e}{sup +}{ital e}{sup {minus}} annihilation into hadrons with data collected by the SLD experiment at SLAC. From fits of the new calculation, complete at {ital O}({alpha}{sub {ital s}}{sup 2}), we obtained {alpha}{sub {ital s}}({ital M}{sub {ital Z}}{sup 2})=0.1184{plus_minus}0.0031(expt){plus_minus}0.0129(theory) (EEC) and {alpha}{sub {ital s}}({ital M}{sub {ital Z}}{sup 2})=0.1120{plus_minus}0.0034(expt){plus_minus}0.0036(theory) (AEEC). The EEC result is significantly lower than that obtained from comparable fits using the {ital O}({alpha}{sub {ital s}}{sup 2}) calculation of Kunszt and Nason.

Abstract: Using an impact parameter tag to select an enriched sample of {ital Z}{sup 0}{r_arrow}{ital bb}{ovr bar} events, and the net momentum-weighted track charge to identify the sign of the charge of the underlying {ital b} quark, we have measured the left-right forward-backward asymmetry for {ital b} quark production as a function of polar angle. Based on 1.8pb{sup {minus}1} of {ital Z}{sup 0} decay data produced with a mean electron beam polarization of {ital P}{sub {ital e}}=63%, this yields a direct measurement of the extent of parity violation in the {ital Zbb} coupling of {ital A}{sub {ital b}}=0.87{plus_minus}0.11(stat){plus_minus}0.09(syst).

Abstract: The parity-violating parameters ${A}_{b}$ and ${A}_{c}$ are directly measured by the SLD experiment at the SLAC Linear Collider in ${e}^{+}{e}^{\ensuremath{-}}$ collisions with polarized electrons at the ${Z}^{0}$ resonance. Leptons with distinctive total and transverse momenta are used to select and analyze ${Z}^{0}\ensuremath{\rightarrow}b\overline{b}$ and ${Z}^{0}\ensuremath{\rightarrow}c\overline{c}$ events. ${A}_{b}$ and ${A}_{c}$ are extracted by forming the left-right forward-backward asymmetry in electron beam polarization and quark polar angle. From our 1993 sample of 1.8 p${\mathrm{b}}^{--1}$ of ${Z}^{0}$ decay data with an average electron beam polarization of 63% we find ${A}_{b}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.91\ifmmode\pm\else\textpm\fi{}0.14$ (stat) $\ifmmode\pm\else\textpm\fi{}0.07$ (syst) and ${A}_{c}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.37\ifmmode\pm\else\textpm\fi{}0.23$ (stat) $\ifmmode\pm\else\textpm\fi{}0.21$ (syst).

Abstract: We have searched for signatures of polarization in hadronic jets from [ital Z][sup 0][r arrow][ital q[bar q]] decays using the jet handedness'' method. The polar angle asymmetry induced by the high SLAC Linear Collider electron-beam polarization was used to separate quark jets from antiquark jets, expected to be left and right polarized, respectively. We find no evidence for jet handedness in our global sample or in a sample of light quark jets, and we set upper limits at the 95% C.L. of 0.063 and 0.099, respectively, on the magnitude of the analyzing power of the method proposed by Efremov [ital et] [ital al].

Abstract: We present a precise measurement of the left-right cross section asymmetry ([ital A][sub [ital L][ital R]]) for [ital Z] boson production by [ital e][sup +][ital e][sup [minus]] collisions. The measurement was performed at a center-of-mass energy of 91.26 GeV with the SLD detector at the SLAC Linear Collider (SLC). The luminosity-weighted average polarization of the SLC electron beam was (63.0[plus minus]1.1)%. Using a sample of 49 392 [ital Z] decays, we measure [ital A][sub [ital L][ital R]] to be 0.1628[plus minus]0.0071(stat)[plus minus]0.0028(syst) which determines the effective weak mixing angle to be sin[sup 2][theta][sub [ital W]][sup eff]=0.2292[plus minus]0.0009(stat) [plus minus]0.0004(syst).

Abstract: We present a measurement of the branching fraction for the rare decays B-->rhoenu and extract a value for the magnitude of V(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 para-metrize the hadronic current in semileptonic decays. Using a sample of 55 x 10(6) BB meson pairs recorded with the BABAR detector at the PEP-II e(+)e(-) storage ring, we obtain B(B0-->rho(-)e(+)nu)=(3.29+/-0.42+/-0.47+/-0.55) x 10(-4) and |V(ub)|=(3.64+/-0.22+/-0.25(+0.39)(-0.56)) x 10(-3), where the uncertainties are statistical, systematic, and theoretical, respectively.

Abstract: We report a study of the B meson decays, B+ --J/psiphiK+, B0 --J/psiphiK(0)(S), B0 --J/psiphi, B0 --J/psieta, and B0 --J/psieta' using 56 x 10(6) B(-)B events collected at the Upsilon(4S) resonance with the BABAR detector at the PEP-II e(+)e(-) asymmetric-energy storage ring. We measure the branching fractions B(B+ --J/psiphiK+)=(4.4+/-1.4(stat)+/-0.5(syst))x 10(-5) and B(B0 --J/psiphiK(0)(S))=(5.1+/-1.9(stat)+/-0.5(syst))x 10(-5), and set upper limits at 90% confidence level for the branching fractions B(B0 --J/psiphi)9.2 x 10(-6), B(B0 --J/psieta)2.7 x 10(-5), and B(B0 --J/psieta')6.3 x 10(-5).

Abstract: A search for B{sub s}{sup 0}-{bar B}{sub s}{sup 0} oscillations is performed using a sample of 400,000 hadronic Z{sup 0} decays collected by the SLD experiment. The B{sub s}{sup 0} candidates are reconstructed in the B{sub s}{sup 0} {yields} D{sub s}{sup -} X channel with D{sub s}{sup -} {yields} {phi}{pi}{sup -}, K*{sup 0} K{sup -}. The B{sub s}{sup 0} production flavor is determined using the large forward-backward asymmetry of polarized Z{sup 0} {yields} b{bar b} decays and charge information in the hemisphere opposite that of the B{sub s}{sup 0} candidate. The decay flavor is tagged by the charge of the D{sub s}{sup {+-}}. From a sample of 361 candidates with an average B{sub s}{sup 0} purity of 40%, we exclude the following values of the oscillation frequency: {Delta}m{sub s} < 1.4 ps{sup -1} and 2.4 < {Delta}m{sub s} < 5.3 ps{sup -1} at the 95% confidence level.

Abstract: We present a measurement of the branching fraction for the rare decays B--rhoenu and extract a value for the magnitude of V(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 para-metrize the hadronic current in semileptonic decays. Using a sample of 55 x 10(6) BB meson pairs recorded with the BABAR detector at the PEP-II e(+)e(-) storage ring, we obtain B(B0--rho(-)e(+)nu)=(3.29+/-0.42+/-0.47+/-0.55) x 10(-4) and |V(ub)|=(3.64+/-0.22+/-0.25(+0.39)(-0.56)) x 10(-3), where the uncertainties are statistical, systematic, and theoretical, respectively.

Abstract: The structure of three-jet e{sup +}e{sup -} {yields} b{bar b}g events has been studied using hadronic Z{sup 0} decays recorded in the SLD experiment at SLAC. Three-jet final states were selected and the CCD-based vertex detector was used to identify two of the jets as b or {bar b}; the remaining jet in each event was tagged as the gluon jet. Distributions of the gluon energy and polar angle with respect to the electron beam were measured over the full kinematic range, and used to test the predictions of perturbative QCD. We find that beyond-leading-order QCD calculations are needed to reproduce the features seen in the data. The energy distribution is sensitive to an anomalous b chromomagnetic moment {kappa} at the b{bar b}g vertex. We measured {kappa} to be consistent with zero and set 95% C.L. limits on its value, -0.06 < {kappa} < 0.04.

Abstract: We present a measurement of the branching fraction for the decay of the neutral B meson into the final state J/psipi(+)pi(-). The data set contains approximately 56 x 10(6) BB pairs produced at the Upsilon(4S) resonance and recorded with the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) storage ring. The result of this analysis is B(B0--J/psipi(+)pi(-))=(4.6+/-0.7+/-0.6) x 10(-5), where the first error is statistical and the second is systematic. In addition, we measure B(B0--J/psirho(0))=(1.6+/-0.6+/-0.4) x 10(-5).

Abstract: The B(0) lifetime was measured with a sample of 23 million BB pairs collected by the BABAR detector at the PEP-II e(+)e(-) storage ring during 1999 and 2000. Events from the semileptonic decay B(0)-->D(*-)l(+)nu(l) have been selected with a partial reconstruction method in which only the charged lepton and the slow pi from the D*--->D(0)pi(-) decay are reconstructed. The result is tau(B(0)) = 1.529+/-0.012(stat)+/-0.029(syst) ps.

Abstract: We present a measurement of the time-dependent CP-violating asymmetries in neutral B decays to the {pi}{sup +}{pi}{sup -} CP eigenstate, and an updated measurement of the charge asymmetry in B{sup 0} {yields} K{sup +} {pi}{sup -} decays. In a sample of 33 million {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the SLAC PEP-II asymmetric B Factory, we find 65{sub -11}{sup +12} {pi}{sup +} {pi}{sup -} and 217 {+-} 18 K{sup +}{pi}{sup -} candidates and measure the asymmetry parameters S{sub {pi}{pi}} = 0.03{sub -0.56}{sup +0.53} {+-} 0.11, C{sub {pi}{pi}} = -0.25{sub -0.47}{sup +0.45} {+-} 0.14, and {Alpha}{sub K{pi}} = -0.07 {+-} 0.08 {+-} 0.02, where the first error is statistical and the second is systematic.

Abstract: We search for direct CP violation in charmless hadronic B decays observed in a sample of about 22.7 million $B\bar{B}$ pairs collected with the BABAR detector at the PEP-II asymmetric-energy $e^+e^-$ collider. We measure the following charge asymmetries: ${\cal A}_{CP} (B^{\pm}\to\eta^\prime K^{\pm}) = -0.11\pm 0.11\pm 0.02$, ${\cal A}_{CP} (B^{\pm}\to\omega \pi^{\pm}) = -0.01^{+0.29}_{-0.31}\pm 0.03$, ${\cal A}_{CP} (B^{\pm}\to\phi K^{\pm}) = -0.05\pm 0.20\pm 0.03$, ${\cal A}_{CP} (B^{\pm}\to\phi K^{*\pm}) = -0.43^{+0.36}_{-0.30}\pm 0.06$, and ${\cal A}_{CP} (B^{0}\to\phi K^{*0}) = 0.00\pm 0.27\pm 0.03$., Comment: 8 pages, 2 postscript figues, submitted to Phys.

Abstract: We measure the branching fractions of the psi(2S) meson to the leptonic final states e+e- and mu+mu- relative to that for psi(2S)-->J/psi pi+pi-. The method uses psi(2S) mesons produced in the decay of B mesons at the Upsilon(4S) resonance in a data sample collected with the BABAR detector at the Stanford Linear Accelerator Center. Using previous measurements for the psi(2S)-->J/psi pi+pi- branching fraction, we determine the e+e- and mu+mu- branching fractions to be 0.0078+/-0.0009+/-0.0008 and 0.0067+/-0.0008+/-0.0007 respectively.

Abstract: We present a limit on the branching fraction for the decay B0-->gammagamma using data collected at the Upsilon(4S) resonance with the BABAR detector at the PEP-II asymmetric energy e+e- collider. Based on the observation of one event in the signal region, out of a sample of 21.3x10(6) e+e--->Upsilon(4S)-->BB decays, we establish an upper limit on the branching fraction of B(B0-->gammagamma)

Abstract: We present a measurement of the decay amplitudes in B-->J/psi K^*(892) channels using 20.7 fb-1 of data collected at the Upsilon(4S) resonance with the BABAR detector at PEP-II. We measure a P-wave fraction R_perp = (16.0+/-3.2+/-1.4)% and a longitudinal polarization fraction (59.7+/-2.8+/-2.4)%. The measurement of a relative phase that is neither 0 nor pi, phi_ll = 2.50+/-0.20+/-0.08 radians, favors a departure from the factorization hypothesis. Although the decay B-->J/psi Kpi proceeds mainly via K^*(892), there is also evidence for K^*_2(1430) and Kpi S-wave contributions.

Abstract: The parity violation parameters A(b) and A(c) of the Zb(b) and Zc(c) couplings have been measured directly, using the polar angle dependence of the polarized cross sections at the Z(0) pole. Bottom and charmed hadrons were tagged via their semileptonic decays. Both the electron and muon analyses take advantage of new multivariate techniques to increase the analyzing power. Based on the 1993-1998 SLD sample of 550,000 Z(0) decays produced with highly polarized electron beams, we measure A(b) = 0.919+/-0.030(stat)+/-0.024(syst), and A(c) = 0.583+/-0.055(stat)+/-0.055(syst).

Abstract: We present the results of searches for B decays to charmless two-body final states containing $\eta^\prime$ or $\omega$ mesons, based on 20.7 fb$^{-1}$ of data collected with the BABAR detector. We find the branching fractions ${\cal B}(B^+\to\eta^\prime K^+) = (70\pm 8\pm 5)\times 10^{-6}$, ${\cal B}(B^0\to\eta^\prime K^0) = (42^{+13}_{-11}\pm 4)\times 10^{-6}$, and ${\cal B}(B^+\to\omega\pi^+)=6.6^{+2.1}_{-1.8}\pm 0.7)\times 10^{-6}$ where the first error quoted is statistical and the second systematic. We give measurements of four additional modes for which the 90% confidence level upper limits are ${\cal B}(B^0\to\omega K^0) < 13\times 10^{-6}$, ${\cal B}(B^+\to\eta^\prime \pi^+) < 12\times 10^{-6}$, ${\cal B}(B^+\to \omega K^+) < 4\times 10^{-6}$, and ${\cal B}(B^0\to\omega\pi^0) < 3\times 10^{-6}$.

Abstract: The B0 and B+ meson lifetimes have been measured in e+e- annihilation data collected in 1999 and 2000 with the BABAR detector at center-of-mass energies near the Upsilon(4S) resonance. Events are selected in which one B meson is fully reconstructed in a hadronic final state while the second B meson is reconstructed inclusively. A combined fit to the B0 and the B+ decay time difference distributions yields tau_{B0} = 1.546 +/- 0.032 (stat) +/- 0.022(syst) ps, tau_{B+} = 1.673 +/- 0.032 (stat) +/- 0.023 (syst) ps and tau_{B+} / tau_{B0} = 1.082 +/- 0.026 (stat) +/- 0.012 (syst)

Abstract: The production of $J/\psi$ mesons in continuum $e^+e^-$ annihilations has been studied with the BABAR detector at energies near the $\Upsilon(4S)$ resonance, approximately 10.6 GeV. The mesons are distinguished from $J/\psi$ production in B decays through their center-of-mass momentum and energy. We measure the cross section $e^+e^-\to J/\psi X$ to be $2.52\pm 0.21\pm 0.21$ pb; for momentum above 2 GeV/c, it is $1.87\pm 0.10\pm 0.15$ pb. We set a 90% confidence level upper limit on the branching fraction for direct $\Upsilon(4S)$\to J/\psi X$ decays at $4.3\times 10^{-4}$.

Abstract: We have observed the decays B--> phiK and phiK(*) in a sample of over 45 million B mesons collected with the BABAR detector at the PEP-II collider. The measured branching fractions are B(B+--> phiK+) = (7.7(+1.6)(-1.4)+/-0.8)x10(-6), B(B0--> phiK0) = (8.1(+3.1)(-2.5)+/-0.8)x10(-6), B(B+--> phiK(*+)) = (9.7(+4.2)(-3.4)+/-1.7)x10(-6), and B(B0--> phiK(*0)) = (8.7(+2.5)(-2.1)+/-1.1)x10(-6). We also report the upper limit B(B+--> phipi(+))

Abstract: We present an updated measurement of time-dependent CP-violating asymmetries in neutral B decays with the BABAR detector at the PEP-II asymmetric B Factory at SLAC. This result uses an additional sample of Upsilon(4S) decays collected in 2001, bringing the data available to 32 x 10(6) BB macro pairs. We select events in which one neutral B meson is fully reconstructed in a final state containing charmonium and the flavor of the other neutral B meson is determined from its decay products. The amplitude of the CP-violating asymmetry, which in the standard model is proportional to sin2 beta, is derived from the decay time distributions in such events. The result sin2 beta = 0.59+/-0.14(stat)+/-0.05(syst) establishes CP violation in the B(0) meson system. We also determine absolute value of lambda = 0.93+/-0.09(stat)+/-0.03(syst), consistent with no direct CP violation.

Abstract: We present a limit on the branching fraction for the decay B0--gammagamma using data collected at the Upsilon(4S) resonance with the BABAR detector at the PEP-II asymmetric energy e+e- collider. Based on the observation of one event in the signal region, out of a sample of 21.3x10(6) e+e---Upsilon(4S)--BB decays, we establish an upper limit on the branching fraction of B(B0--gammagamma)1.7x10(-6) at the 90% confidence level. This result substantially improves upon existing limits.

Abstract: We present a measurement of the decay amplitudes in B--J/psiK*(892) channels using 20.7 fb(-1) of data collected at the Upsilon(4S) resonance with the BABAR detector at PEP-II. We measure a P-wave fraction R(perpendicular) = (16.0 +/- 3.2 +/- 1.4)% and a longitudinal polarization fraction (59.7 +/- 2.8 +/- 2.4)%. The measurement of a relative phase that is neither 0 nor pi, phi = 2.50 +/- 0.20 +/-0.08 radians, favors a departure from the factorization hypothesis. Although the decay B--/psiK(pi) proceeds mainly via K*(892), there is also evidence for K2*(1430) and K(pi) S-wave contributions.
