Available in PDF, EPUB and Kindle. Book excerpt: We present a preliminary measurement of the inclusive production rates of K[sub s], A and X hadrons produced in e[sup +]e[sup [minus]] annihilation at the Z[sup 0] pole. The analysis is based upon approximately 50K Z[sup 0] decays collected in the SLD experiment at SLAC in 1993. The observed rates of (K[sub s]) = 1.02 [plus-minus] 0.02 [plus-minus] 0.09 and ([Lambda]) + ([bar [Lambda]]) = 0.38 [plus-minus] 0.01 [plus-minus] 0.04 are consistent with previous measurements. Our differential cross section peak-position results are shown to be consistent with QCD predictions based on the modified leading logarithm approximation and local parton-hadron duality.

Download or read book Preliminary Measurements of Production Of?{sup {plus_minus}}, K{sup {plus_minus}}, P, K° And?° in Hadronic Z° Decays written by and published by . This book was released on 1996 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have measured production of?{sup {+-}},?{sup {+-}}, {ital p}/{ital {bar p}},?° and?°/{bar?}° as a function of momentum in inclusive hadronic {ital Z}° decay events and separately in events containing primary light-({ital uds}) and {ital b}-quarks. The SLD Cherenkov Ring Imaging Detector was used to identify charged pions, kaons, and protons over most of the available momentum range 0.8>{ital p}>33 GeV/c. The neutral?°{sub s} and {Lambda}° were reconstructed using the??− and {ital p}?− decay modes, respectively. We present the first comparisons of momentum of charged tracks measured in the SLD Vertex Detector. Substantial differences are observed, consistent with the kinematics of {ital B}-hadron production in Z° decays and the properties of {ital B}-hadron decays as measured at lower energies.

Download or read book Preliminary Measurement of Leading Particle Effects in Hadronic Z[sup 0] Decays written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present preliminary evidence for leading particle production in hadronic decays of the Z[sup 0] to light quark pairs using 150,000 events recorded in the SLD experiment at SLAC. The highly polarized electron beam produced by the SLC is used to tag quark and antiquark jets, and a signed impact parameter technique is employed to reject heavy flavor events. Charged hadrons are identified in the SLD Cherenkov Ring Imaging Detector (CRID) and[Lambda]/[bar[Lambda]] are reconstructed using their charged decay modes. In a high purity sample of quark jets, the baryon momentum spectrum is harder that that of the antibaryon, and conversely for a sample of antiquark jets, supporting the hypothesis that the faster particles in jets are more likely to carry the primary quark or antiquark from the Z[sup 0] decay. Similarly, more high momentum K[sup -] that K[sup+] are observed in quark jets and conversely for antiquark jets, consistent with the hypothesis that leading K[sup[+-]] are produced predominantly in s[bar s] events rather than[ital u][bar[ital u]] events.

Available in PDF, EPUB and Kindle. Book excerpt: We present a preliminary measurement of the inclusive production rates of K{sub s}, A and X hadrons produced in ee− annihilation at the Z° pole. The analysis is based upon approximately 50K Z° decays collected in the SLD experiment at SLAC in 1993. The observed rates of (K{sub s}) = 1.02 ± 0.02 ± 0.09 and ([Lambda]) + ({bar {Lambda}}) = 0.38 ± 0.01 ± 0.04 are consistent with previous measurements. Our differential cross section peak-position results are shown to be consistent with QCD predictions based on the modified leading logarithm approximation and local parton-hadron duality.

Download or read book Production Of?{sup {plus_minus}}, K{sup {plus_minus}}, P, K°{sub S},?°, K{sup *0} And? in Hadronic Z° Decays written by and published by . This book was released on 1996 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Production rates and momentum distributions have been measured for?{sup {+-}}, K{sup {+-}}, p, K°{sub s},?°, K{sup *0} and? in 150,000 hadronic Z° decays recorded by the SLD detector at the SLD collider at SLAC. The analysis uses the SLD Cerenkov Ring Imaging Detector (CRID) for clean and efficient identification of charged tracks and significant background reduction. In addition, K{sup *0} production has been studied in quark and anti-quark jet samples, which were identified by their electroweak forward backward asymmetries using the SLD high electron beam polarization. A difference between the two samples is observed in the K{sup *0} rate at high momentum, consistent with leading particle and strangeness suppression hypotheses.

Book Synopsis Measurement of the Q2 Dependence of the Hadronic Form Factor in D0 to K- E+ Nu_e Decays by : B. Aubert

This book was released on 2006 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: A preliminary measurement of the q{sup 2} dependence of the D{sup 0} {yields} K{sup -}e{sup +}{nu}{sub e} decay rate is presented. This rate is proportional to the hadronic form factor squared, specified by a single parameter. This is either the mass in the simple pole ansatz m{sub pole} = (1.854 {+-} 0.016 {+-} 0.020) GeV/c{sup 2} or the scale in the modified pole ansatz {alpha}{sub pole} = 0.43 {+-} 0.03 {+-} 0.04. The first error refers to the statistical, the second to the systematic uncertainty.

Download or read book Measurements of Hadronic Decays of Z[sup 0] Bosons written by and published by . This book was released on 1992 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Z[degrees] bosons have been produced by collisions of longitudinally polarized electrons with unpolarized positrons at the SLAC Linear Collider and their decays have been recorded by the SLD experiment. We present preliminary measurements of the properties of the resulting Z[degrees] decays into multi-hadronic final states. We find good agreement with the predictions of perturbative QCD and fragmentation models.
Book Synopsis The Production of [pi]{sup {+-}}, K{sup {+-}}, P, K° and [Lambda]° in Hadronic Z° Decays by :
Download or read book The Production of [pi]{sup {+-}}, K{sup {+-}}, P, K° and [Lambda]° in Hadronic Z° Decays written by and published by . This book was released on 1995 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors have measured production fractions and spectra for [pi]{sup {+-}}, K{sup {+-}} and p, and production spectra for K° and [Lambda]° in both hadronic Z° decays and a Z° → light quark (uds) subset at SLD. The SLD Cherenkov Ring Imaging Detector was used to identify charged hadrons. The CCD vertex detector was used to select the enriched uds sample. For the global sample, the results are consistent with previous experiments. The authors observe a clear flavor dependence in production spectra, but only a small effect in hadron fractions and [xi] = ln(1/x{sub p}) peak positions.

Download or read book Measurement of the B--]J/psi K*(892) Decay Amplitudes written by and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present a measurement of the decay amplitudes in B[yields] J/[psi] K*(892) channels using 20.7 fb[sup -1] of data collected at the[Upsilon](4S) resonance with the BABAR detector at PEP-II. They 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], [psi][parallel]= 2.50[+-] 0.20[+-] 0.08 radians, favors a departure from the factorization hypothesis. Although the decay B[yields] J/[psi] K[pi] proceeds mainly via K*(892), there is also evidence for K*[sub 2](1430) and K[pi] S-wave contributions.
