Abstract: The Heavy Photon Search experiment took its first data in a 2015 engineering run using a 1.056 GeV, 50 nA electron beam provided by CEBAF at the Thomas Jefferson National Accelerator Facility, searching for a prompt, electroproduced dark photon with a mass between 19 and 81 MeV/c2. A search for a resonance in the e+e- invariant mass distribution, using 1.7 days (1170 nb-1) of data, showed no evidence of dark photon decays above the large QED background, confirming earlier searches and demonstrating the full functionality of the experiment. Upper limits on the square of the coupling of the dark photon to the standard model photon are set at the level of 6×10-6. Future runs with higher luminosity will explore new territory.

Abstract: The authors present a measurement of the left-right cross-section asymmetry (ALR) for Z boson production by e{sup +}e{sup {minus}} collisions. The measurement includes the final data taken with the SLD detector at the SLAC Linear Collider (SLC) during the period 1996--1998. Using a sample of 383,487 Z decays collected during the 1996-1998 runs they measure the pole-value of the asymmetry, A{sub LR}{sup 0}, to be 0.15056 {+-} 0.00239 which is equivalent to an effective weak mixing angle of sin{sup 2}Sigma{sub W}{sup eff} = 0.23107 {+-} 0.00030. The result for the complete 1992--1998 dataset comprising 537 thousand Z decays is sin{sup 2}Sigma{sub W}{sup eff} = 0.23097 {+-} 0.00027.

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: 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: 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 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 measurements of Rb using the SLD at the SLC. The analyses use 2D and 3D impact parameter tags and a displaced 3D vertex tag which all exploit the small size and stability of the e+e- interaction point and the precision 3D CCD pixel vertex detector to achieve high bb¯-tagging efficiencies and purities. The combined measurement yields Rb=0.229±0.011 and is consistent with standard model predictions.

Abstract: We report a measurement of the average {ital B} hadron lifetime using data collected with the SLD detector at the SLAC Linear Collider in 1993. An inclusive analysis selected three-dimensional vertices with {ital B} hadron lifetime information in a sample of 50{times}10{sup 3} {ital Z}{sup 0} decays. A lifetime of 1.564{plus_minus}0.030(stat){plus_minus}0.036(syst) ps was extracted from the decay length distribution of these vertices using a binned maximum likelihood method. {copyright} {ital 1995} {ital The} {ital American} {ital Physical} {ital Society}.

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: 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: 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 determine the strong coupling ${\mathrm{\ensuremath{\alpha}}}_{\mathit{s}}$ from a comprehensive study of energy-energy correlations (EEC's) and their asymmetry (AEEC's) in hadronic decays of ${\mathit{Z}}^{0}$ bosons collected by the SLD experiment at SLAC. The data are compared with all four available predictions of QCD calculated up to O(${\mathrm{\ensuremath{\alpha}}}_{\mathit{s}}^{2}$) in perturbation theory, and also with a resummed calculation matched to all four of these calculations. We find large discrepancies between ${\mathrm{\ensuremath{\alpha}}}_{\mathit{s}}$ values extracted from the different O(${\mathrm{\ensuremath{\alpha}}}_{\mathit{s}}^{2}$) calculations. We also find a large renormalization scale ambiguity in ${\mathrm{\ensuremath{\alpha}}}_{\mathit{s}}$ determined from the EEC's using the O(${\mathrm{\ensuremath{\alpha}}}_{\mathit{s}}^{2}$) calculations; this ambiguity is reduced in the case of the AEEC's and is very small when the matched calculations are used. Averaging over all calculations, and over the EEC and AEEC results, we obtain ${\mathrm{\ensuremath{\alpha}}}_{\mathit{s}}$(${\mathit{M}}_{\mathit{Z}}^{2}$)=0.${124}_{\mathrm{\ensuremath{-}}0.004}^{+0.003}$ (expt.) \ifmmode\pm\else\textpm\fi{}0.009 (theory).

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: Using an impact parameter tag to select an enriched sample of [ital Z][sup 0][r arrow][ital b[bar b]] events, we have measured the difference between the average charged multiplicity of [ital Z][sup 0][r arrow][ital b[bar b]] and [ital Z][sup 0][r arrow] hadrons to be [ital [bar n]][sub [ital b]][minus][ital [bar n]][sub had]=2.24[plus minus]0.30 ( stat )[plus minus]0.33 ( syst ) tracks per event. From this, we have derived [ital [bar n]][sub [ital b]][minus][ital [bar n]][sub [ital u][ital d][ital s]]=3.31[plus minus]0.41[plus minus]0.79. Comparing this measurement with those at lower center-of-mass energies, we find no evidence that [ital [bar n]][sub [ital b]][minus][ital [bar n]][sub [ital u][ital d][ital s]] depends on energy. This result is in agreement with a precise prediction of perturbative QCD, and supports the notion that QCD remains asymptotically free down to the scale [ital M][sub [ital b]][sup 2].

Abstract: We present a search at the Jefferson Laboratory for new forces mediated by sub-GeV vector bosons with weak coupling α' to electrons. Such a particle A' can be produced in electron-nucleus fixed-target scattering and then decay to an e + e- pair, producing a narrow resonance in the QED trident spectrum. Using APEX test run data, we searched in the mass range 175-250 MeV, found no evidence for an A'→ e+ e- reaction, and set an upper limit of α'/α ~/= 10(-6). Our findings demonstrate that fixed-target searches can explore a new, wide, and important range of masses and couplings for sub-GeV forces.

Abstract: We present the first measurement of the left-right cross section asymmetry (${\mathit{A}}_{\mathit{L}\mathit{R}}$) for Z boson production by ${\mathit{e}}^{+}$${\mathit{e}}^{\mathrm{\ensuremath{-}}}$ collisions. The measurement was performed at a center-of-mass energy of 91.55 GeV with the SLD detector at the SLAC Linear Collider which utilized a longitudinally polarized electron beam. The average beam polarization was (22.4\ifmmode\pm\else\textpm\fi{}0.6)%. Using a sample of 10 224 Z decays, we measure ${\mathit{A}}_{\mathit{L}\mathit{R}}$ to be 0.100\ifmmode\pm\else\textpm\fi{}0.044(stat)\ifmmode\pm\else\textpm\fi{}0.004(syst), which determines the effective weak mixing angle to be ${\mathrm{sin}}^{2}$${\mathrm{\ensuremath{\theta}}}_{\mathit{W}}^{\mathit{e}\mathit{f}\mathit{f}}$=0.2378 \ifmmode\pm\else\textpm\fi{}0.0056(stat)\ifmmode\pm\else\textpm\fi{}0.0005(syst).

Abstract: Any future high energy e+e- linear collider aims at precision measurements of Standard Model quantities as well as of new, not yet discovered phenomena. In order to pursue this physics programme, excellent detectors at the interaction region have to be complemented by beam diagnostics of unprecedented precision. This article gives an overview of current plans and issues for polarimeters and energy spectrometers at the International Linear Collider, which have been designed to fulfill the precision goals at a large range of beam energies from 45.6 GeV at the Z pole up to 250 GeV or, as an upgrade, up to 500 GeV., Reference paper for the "Letter of Intent" documents of all ILC detector concepts; 15 pages, 9 figures; as accepted by JINST. Improved figure quality and some changes to the text, but basic content unchanged

The most prominent enhancement in the 3{pi} spectrum occurs at a mass and with a width consistent with the parameters of the {ital a}{sub 2}(1320). This identification is confirmed by the various angular distributions. The {ital a}{sub 2} production cross section, corrected for efficiencies and alternate {ital a}{sub 2} decay modes, is 0.45{plus minus}0.05 {mu}b.

Abstract: Data taken by the Mark II detector at the PEP storage ring was used to measure the rate of dilepton production in multihadronic events produced by e + e − annihilation at √ s =29 GeV. We determine the probability that a hadron initially containing a b (b) quark decays to a positive (negative) lepton to be 0.17 −0.08 +0.15 , with 90% confidence level limits of 0.06 and 0.38.

Abstract: One of the two ILC Interaction Regions will have a large horizontal crossing angle which would allow to extract the spent beams in a separate beam line. In this paper, the extraction line design for 20 mrad crossing angle is presented. This beam line transports the primary e+/e- and beam-strahlung photon beams from the IP to a common dump, and includes diagnostic section for energy and polarization measurements. The optics is designed for a large energy acceptance to minimize losses in the low energy tail of the disrupted beam. The extraction optics, diagnostic instrumentation and particle tracking simulations are described. © 2005 IEEE.

Abstract: We measure the hadronic branching ratios of the Z0 boson into heavy quarks: Rb=Gamma(Z0->bb)/Gamma(Z0->hadrons) and Rc=Gamma(Z0->cc/Gamma(Z0->hadrons) using a multi-tag technique. The measurement was performed using about 400,000 hadronic Z0 events recorded in the SLD experiment at SLAC between 1996 and 1998. The small and stable SLC beam spot and the CCD-based vertex detector were used to reconstruct bottom and charm hadron decay vertices with high efficiency and purity, which enables us to measure most efficiencies from data. We obtain, Rb=0.21604 +- 0.00098(stat.) +- 0.00073(syst.) -+ 0.00012(Rc) and, Rc= 0.1744 +- 0.0031(stat.) +- 0.0020(syst.) -+ 0.0006(Rb), 37 pages, 8 figures, to be submitted to Phys. Rev. D version 2: changed title to ratios, used common D production fractions for Rb and Rc and corrected Zgamma interference. Identical to PRD submission

Abstract: Exploiting the manipulation of the SLAC Linear Collider electron-beam polarization, we present precise direct measurements of the parity-violation parameters A(c) and A(b) in the Z-boson-c-quark and Z-boson-b-quark coupling. Quark-antiquark discrimination is accomplished via a unique algorithm that takes advantage of the precise SLAC Large Detector charge coupled device vertex detector, employing the net charge of displaced vertices as well as the charge of kaons that emanate from those vertices. From the 1996-1998 sample of 400 000 Z decays, produced with an average beam polarization of 73.4%, we find A(c)=0.673+/-0.029(stat)+/-0.023(syst) and A(b)=0.919+/-0.018(stat)+/-0.017(syst).

Abstract: We present improved measurements of the differential production rates of stable charged particles in hadronic Z{sup 0} decays, and of charged pions, kaons and protons identified over a wide momentum range using the SLD Cherenkov Ring Imaging Detector. In addition to flavor-inclusive Z{sup 0} decays, measurements are made for Z{sup 0} decays into light (u, d, s), c and b primary flavors, selected using the upgraded Vertex Detector. Large differences between the flavors are observed that are qualitatively consistent with expectations based upon previously measured production and decay properties of heavy hadrons. These results are used to test the predictions of QCD in the Modified Leading Logarithm Approximation, with the ansatz of Local Parton-Hadron Duality, and the predictions of three models of the hadronization process. The light-flavor results provide improved tests of these predictions, as they do not include the contribution of heavy-hadron production and decay; the heavy-flavor results provide complementary model tests. In addition we have compared hadron and antihadron production in light quark (as opposed to antiquark) jets. Differences are observed at high momentum for all three charged hadron species, providing direct probes of leading particle effects, and stringent constraints on models.

Abstract: We present a measurement of the b-quark inclusive fragmentation function in ${Z}^{0}$ decays using a novel kinematic B-hadron energy reconstruction technique. The measurement was performed using 350 000 hadronic ${Z}^{0}$ events recorded in the SLD experiment at SLAC between 1997 and 1998. The small and stable SLC beam spot and the charge-coupled-device--based vertex detector were used to reconstruct B-decay vertices with high efficiency and purity, and to provide precise measurements of the kinematic quantities used in this technique. We measured the B energy with good efficiency and resolution over the full kinematic range. We compared the scaled B-hadron energy distribution with models of b-quark fragmentation and with several ad hoc functional forms. A number of models and functions are excluded by the data. The average scaled energy of weakly decaying B hadrons was measured to be $〈{x}_{b}〉=0.709\ifmmode\pm\else\textpm\fi{}0.003(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.003(\mathrm{syst})\ifmmode\pm\else\textpm\fi{}0.002(\mathrm{model}).$

Abstract: New measurements of Ds+ and Ds*+ meson production rates from B decays and from qqbar continuum events near the Y(4S) resonance are presented. Using 20.8 fb-1 of data on the Y(4S) resonance and 2.6 fb-1 off resonance, we find the inclusive branching fractions BR(B --> Ds+ X) = (10.93+/-0.19+/-0.58+/-2.73)% and BR(B --> Ds*+ X) = (7.9+/-0.8+/-0.7+/-2.0)%, where the first error is statistical, the second is systematic, and the third is due to the Ds+ --> phi pi+ branching fraction uncertainty. The branching fractions SumBR(B --> Ds(*)+ Dbar(*)) = (5.07+/-0.14+/-0.30+/-1.27)% and SumBR(B --> Ds*+ Dbar(*)) = (4.1+/-0.2+/-0.4+/-1.0)% are determined from the Ds(*)+ momentum spectra.

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: The branching fractions of the exclusive decays $B^0\to K^{*0}\gamma$ and $B^+ \to K^{*+}\gamma$ are measured from a sample of $(22.74\pm 0.36)\times 10^6$ $B\bar B$ decays collected with the BABAR detector at the PEP II asymmetric $e^{+}e^{-}$ collider. We find ${\cal B}(B^0\to K^{*0}\gamma) = (4.23\pm 0.40({\rm stat.})\pm 0.22({\rm sys.}))\times 10^{-5}$, ${\cal B}(B^+\to K^{*+}\gamma) = (3.83\pm 0.62({\rm stat.})\pm 0.22({\rm sys.}))\times 10^{-5}$ and constrain the CP-violating charge asymmetry to be $-0.170 < A_{CP}(B \to K^*\gamma) < 0.082$ at 90% C.L.

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 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: 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 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 present measurements of the branching fractions and a search for CP-violating charge asymmetries in charmless hadronic decays of B mesons into two-body final states of kaons and pions. The results are based on a data sample of approximately 23 million BB(bar) pairs collected by the BABAR detector at the PEP-II asymmetric B Factory at SLAC. We find the following branching fractions: BF(B0-->pi+pi-)= (4.1+/-1.0+/-0.7) x 10^{-6}, BF(B0-->K+pi-)=(16.7+/-1.6+/-1.3) x 10^{-6}, BF(B+-->K+pi0)=(10.8^{+2.1}_{-1.9}+/-1.0) x 10^{-6}, BF(B+-->K0pi+)=(18.2^{+3.3}_{-3.0}+/-2.0) x 10^{-6}, BF(B0-->K0pi0)=(8.2^{+3.1}_{-2.7}+/-1.2) x 10^{-6}. We also report the 90% confidence level upper limits BF(B0-->K+K-) pi+pi0) anti-K0K+) < 2.4 x 10^{-6}. In addition, charge asymmetries have been measured and found to be consistent with zero, where the statistical precision is in the range of +/-0.10 to +/-0.18, depending on the decay mode.

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 have measured gluon splitting into bottom quarks, g -> b bbar, in hadronic Z0 decays collected by SLD between 1996 and 1998. The analysis was performed by looking for secondary bottom production in 4-jet events of any primary flavor. 4-jet events were identified, and in each event a topological vertex-mass technique was applied to the two jets closest in angle in order to identify them as b or bbar jets. The upgraded CCD vertex detector gives very high B-tagging efficiency, especially for B hadrons with the low energies typical of this process. We measured the rate of g -> b bbar production per hadronic event, g_bb, to be (2.44+-0.59 (stat) +-0.34 (syst)) X10**-3., 21 pages, 11 figures; submitted to Physics Letters B

Abstract: We present a direct measurement of the parity-violation parameter A{sub c} in the coupling of the Z{sup 0} to c-quarks with the SLD detector. The measurement is based on a sample of 530k hadronic Z{sup 0} decays, produced with a mean electron-beam polarization of |P{sub e}| = 73%. The tagging of c-quark events is performed using two methods: the exclusive reconstruction of D*{sup +}, D{sup +}, and D{sup 0} mesons, and the soft-pions ({pi}{sub s}) produced in the decay of D*{sup +} {yields} D{sup 0}{pi}{sub s}{sup +}. The large background from D mesons produced in B hadron decays is separated efficiently from the signal using precision vertex information. The combination of these two methods yields A{sub c} = 0:688 {+-} 0:041.

Abstract: We present the first measurement of the left-right cross-section asymmetry (ALR) in Z-boson production observed at the SLAC Linear Collider. In 1992 the SLD detector recorded 10 224 Z events produced by the collision of longitudinally polarized electrons with an unpolarized positron beam at a center-of-mass energy of 91.55 GeV. The average electron beam polarization during the run was (22.4 ± 0.6)%. We measure ALR to be 0.100 ± 0.0440 (stat.) ±0.004 (syst.), which determines the effective weak mixing angle to be $\sin^2\theta_W^{\rm {eff}} = 0.2378\pm 0.0056\, ({\rm stat.})\pm 0.0005\, ({\rm syst.})$.

Abstract: We perform an isospin and partial-wave analysis of the low-mass Nπ system in πN → π(Nπ) using new data at 14 GeV/c in the interval 0.02 < tππ < 0.5 GeV2. We study the diffractive background by means of its interference with the Δ and find that a considerable fraction of this background has spin-parity 12− and does not obey the Gribov-Morrison rule. Using a model for Δ production the helicity amplitudes for diffractive production and their phases can be estimated.

Abstract: We have studied the reaction γp → pπ+π− + neutrals in the LBL-SLAC 82″ hydrogen bubble chamber exposed to a linearly polarized photon beam at 2.8., 4.7 and 9.3. GeV. We observe an enhancement at 1.24 GeV in the mesonic mass recoiling against the proton. The enhancement is produced peripherally with slopes of 5−7 GeV−2 and cross sections of 1−3 μb. We show that ωπo is likely to be the major decay mode and give upper limits for other decay modes. The enhancement can be either the JP = 1+ B meson, a yet unestablished JP = 1− meson decaying via ωπo, or a diffractively produced Deck-type background. The observed decay correlations are compatible with an s-channel helicity conserving production process. Our data at higher masses are consistent with a ϱϵ decay of the ϱ′(1600) and we obtain an upper limit of 4±1 μb for ϱ′(1600) production in the final state pπ+π− + neutrals at 9.3 GeV.

Abstract: We have measured in a single experimental setup, the differential cross sections and decay angular distributions of the Y∗ (1385) produced in the two line-reversed reactions: π + p → K + Y ∗+ (1385) (279 events/ω b ) and K − p → π − Y ∗+ (1385) (190 events/ωb) at 11.5 GeV/c. The data have been derived from a triggered bubble-chamber experiment using the SLAC Hybrid Facility. We find the differential cross sections and Y∗ polarizations for the two reactions to be in agreement with exchange-degeneracy predictions, if kinematic differences are taken into account. The Stodolsky-Sakurai and additive quark model predictions are in agreement with the main features of the decay angular distributions of the Y∗ (1385), except for small violations at low momentum transfer, which can be associated with a finite helicity non-flip contribution in the forward direction.
