3. Observation of high momentum eta(l) production in B decays

Author

Browder, T, Li, Y, Rodriguez, J, Bergfeld, T, Eisenstein, B, Ernst, J, Gladding, G, Gollin, G, Hans, R, Johnson, E, Karliner, I, Marsh, M, Palmer, M, Selen, M, Thaler, J, Edwards, K, Bellerive, A, Janicek, R, MacFarlane, D, Patel, P, Sadoff, A, Ammar, R, Baringer, P, Bean, A, and Besson, D

Abstract

We report the first observation of B → η′X transitions with high momentum η′ mesons. We observe 39.0 ± 11.6 B decay events with 2.0 < pη′ < 2.7 GeV/c, the high momentum region where background from b → c processes is suppressed. We discuss the physical interpretation of the signal, including the possibility that it is due to b → sg* transitions. Given that interpretation, we find B(B → η′Xs) = [6.2 ± 1.6(stat) ±1.3(syst)1.50.0(bkg)] × 10-4 for 2.0 < pη′ < 2.7 GeV/c.

4. Measurement of the B̄ → Dlv̄ Partial width and form factor parameters

Author

Athanas, M, Avery, P, Jones, C, Lohner, M, Prescott, C, Yelton, J, Zheng, J, Brandenburg, G, Briere, R, Ershov, A, Gao, Y, Kim, D, Wilson, R, Yamamoto, H, Browder, T, Li, F, Li, Y, Rodriguez, J, Bergfeld, T, Eisenstein, B, Ernst, J, Gladding, G, Gollin, G, Hans, R, and Johnson, E

Abstract

We have studied the decay B̄ → Dlv̄, where l = e or μ. From a fit to the differential decay rate dΓ/dw we measure the rate normalization FD(1)|Vcb| and form factor slope ρ̂D2, and, using measured values of τB, find Γ(B̄ → Dlv̄) = (12.0 ± 0.9 ± 2.1) ns-1. The resulting branching fractions are B(B̄0 → D+l-v̄) = (1.87 ± 0.15 ± 0.32)% and B(B- → D0l v̄) = (1.94 ± 0.15 ± 0.34)%. The form factor parameters are in agreement with those measured in B̄ → D*lv̄ decays, as predicted by heavy quark effective theory.

5. Search for CP violation in τ → ππ0ντ decay

Author

Abstract

We search for CP nonconservation in the decays of τ leptons produced via e+e- annihilation at √s ∼ 10.6 GeV. The method uses correlated decays of pairs of τ leptons, each decaying to the ππ0ντ final state. The search is done within the framework of a model with a scalar boson exchange. In an analysis of a data sample corresponding to 12.2×106 produced τ pairs collected with the CLEO detector, we find no evidence of violation of CP symmetry. We obtain a limit on the imaginary part of the coupling constant parametrizing the relative contribution of diagrams that would lead to CP violation to be -0.046

Abstract

We have searched for two-body charmless decays of B mesons to purely hadronic exclusive final states including ω or φ mesons using data collected with the CLEO II detector. With this sample of 6.6 × 106 B mesons we observe a signal for the ωK+ final state, and measure a branching fraction of B(B+ = 1.5-0.610.7± 0.2) × 10-5. We also observe some evidence for the φK* final state, and upper limits are given for 22 other decay modes. These results provide the opportunity for studies of theoretical models and physical parameters.

8. Study of exclusive two-body B-omicron meson decays to charmonium

Abstract

We present a study of three B0 decay modes useful for time-dependent CP asymmetry measurements. From a sample of 9.7×106 BB̄ meson pairs collected with the CLEO detector, we have reconstructed B0 →J/ψKS0, B0→χclKS0, and B0→J/ψπ0 decays. The latter two decay modes have been observed for the first time. We describe a KS0→π0π0 detection technique and its application to the reconstruction of the decay B0 →J/ψKS0. Combining the results obtained using KS0→π+π- and KS0→π0π0 decays, we determine B(B0 →J/ψK0)=(9.5±0.8±0.6)×10-4, where the first uncertainty is statistical and the second one is systematic. We also obtain B(B0→χclK0)=(3.9-1.3+1.9±0.4)×10-4 and B(B0→J/ψπ0)=(2.5-0.9+1.1±0.2)×10-5. ©2000 The American Physical Society.

No signal is found, and the following upper limits on the branching fractions are established: B(B0→e+e-)27 TeV is established at 90% confidence level. © 2000 The American Physical Society.

Abstract

We have used the CLEO II detector to study the multiplicity of charged particles in the decays of B mesons produced at the Y(4S) resonance. Using a sample of 1.5×106 B meson pairs, we find the mean inclusive charged particle multiplicity to be 10.71±0.02-0.15+0.21 for the decay of the pair. This corresponds to a mean multiplicity of 5.36±0.01-0.08+0.11 for a single B meson. Using the same data sample, we have also extracted the mean multiplicities in semileptonic and nonleptonic decays. We measure a mean of 7.82±0.05-0.19+0.21 charged particles per BB̄ decay when both mesons decay semileptonically. When neither B meson decays semileptonically, we measure a mean charged particle multiplicity of 11.62±0.04-0.18+0.24 per BB̄ pair. ©2000 The American Physical Society.

Abstract

We present an observation and time-integrated rate measurement of the decay D(0)-->K(+)pi(-)pi(0) produced in 9 fb(-1) of e(+)e(-) collisions near the Upsilon(4S) resonance. The signal is inconsistent with an upward fluctuation of the background by 4.9 standard deviations. We measured the time-integrated rate of D(0)-->K(+)pi(-)pi(0) normalized to the rate of D(0)-->K(+)pi(-)pi(0) to be 0.0043(+0.0011)(-0.0010) (stat)+/-0.0007 (syst). This decay can be produced by doubly Cabibbo-suppressed decays or by the D(0) evolving into a D(0) through mixing, followed by a Cabibbo-favored decay to K(+)pi(-)pi(0). We also found the CP asymmetry A = (9(+25)(-22))% be consistent with zero.

Abstract

We have observed new channels for τ decays with an η in the final state. We study 3-prong tau decays, using the η → γγ and η → 3π0 decay modes and 1-prong decays with two π0's using the η → γγ channel. The measured branching fractions are B(τ- → π- π- π+ ηντ) = (3.4-0.5+0.6 ± 0.6) × 10-4 and B(τ- → π- 2π0ηντ) = (1.4 ± 0.6 ± 0.3) × 10-4. We observe clear evidence for f1 → ηππ substructure and measure B(τ- → f1π- ντ) = (5.8;-1.3+1.4 ± 1.8) × 10-4. We have also searched for η′(958) production and obtain 90% C.L. upper limits B(τ- → π- η′ ντ) < 7.4 × 10-5 and B(τ- → π- π0 η′ντ < 8.0 × 10-5.

Abstract

An analysis of 9.66 × 106 charged B meson decays which results in a conservative upper limit on the branching fraction B(B → τν) < 8.4 × 10-4. The analysis was slightly modified to establish B(B± → K± νν̄) < 2.4 × 10-4. The method used is optimized for conditions available at Y(4S) experiments, and some application of the method to other rare decay modes with large missing energy was aniticipated.

Abstract

Based on a sample of approximately 500,000 hadronic Z0 decays accumulated between 1993 and 1998, the SLD experiment has set limits on 24 fully charged two-body and quasi two-body exclusive charmless hadronic decays of B+, B0, and B0_s mesons. The precise tracking capabilities of the SLD detector provided for the efficient reduction of combinatoric backgrounds, yielding the most precise available limits for ten of these modes., Comment: LaTex, 11 pages, 2 figures, uses RevTeX. This version contains minor changes suggested by Phys Rev D reviewers. Previous version was the original resubmission to Physical Review D, Rapid Communications, after rejection from Physical Review Letters.

Abstract

Using 12.7 fb(-1) of data collected with the CLEO detector at CESR, we observed two-photon production of the cc states chi(c0) and chi(c2) in their decay to pi(+)pi(-)pi(+)pi(-). We measured gamma(gammagamma)(chi(c))xB(chi(c)-->pi(+)pi(-)pi(+)pi(-)) to be 75+/-13(stat)+/-8(syst) eV for the chi(c0) and 6.4+/-1.8(stat)+/-0.8(syst) eV for the chi(c2), implying gamma(gammagamma)(chi(c0)) = 3.76+/-0.65(stat)+/-0.41(syst)+/-1.69(br) keV and gamma(gammagamma)(chi(c2)) = 0.53+/-0.15(stat)+/-0.06(syst)+/-0.22(br) keV. Also, cancellation of dominant experimental and theoretical uncertainties permits a precise comparison of gamma(gammagamma)(chi(c0))/gamma(gammagamma)(chi(c2)), evaluated to be 7.4+/-2.4(stat)+/-0.5(syst)+/-0.9(br), with QCD-based predictions.

Abstract

The parity violation parameters Ab and Ac of the Zbb ̄ and Zcc ̄ 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 Čerenkov Ring Imaging Detector. Based on the 1993–1995 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 Ab in the Z0 to bb̄ coupling using a new technique to distinguish the b and b̄ quarks using charged kaons from B decays. The Z0 bosons are produced in e+ē collisions at the SLC with longitudinally polarized electrons. bb̄ events are selected using a secondary vertex mass tag and Ab is determined from the left-right forward-backward asymmetry. From the 1994–1995 data sample, selected from 100 000 hadronic Z0 decays, we obtain Ab = 0.855 ± 0.088stat ± 0.102syst.

Abstract

We present a direct measurement of the parity-violation parameter Ab using a self-calibrating track-charge technique. In the SLAC Linear Collider Large Detector (SLD) experiment we observe hadronic decays of Z0 bosons produced in collisions between longitudinally polarized electrons and unpolarized positrons at the SLAC Linear Collider. A sample of bb events is selected using the topologically reconstructed mass of B hadrons. From our 1993–1995 sample of approximately 150 000 hadronic Z0 decays we obtain Ab = 0.911 ± 0.045(stat)±0.045(syst).

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 SLAG. 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(EB))=0.716+/-0.011(stat)(-0.022)(+0.021)(syst).

Abstract

We present the first measurement of the left-right charge asymmetry [Formula presented] in hadronic Z boson decays. This was performed at [Formula presented] with the SLD at the SLAC Linear Collider with a polarized electron beam. Using 89838 events, we obtain [Formula presented] which leads to a measurement of the electron left-right asymmetry parameter, [Formula presented], and [Formula presented]. Also, the [Formula presented] measurement combined with the left-right cross section asymmetry determines A_e independently of the value of the electron-beam polarization.

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

Average charged multiplicities have been measured separately in b, c and light quark (u, d, s) events from Z0 decays measured in the SLD experiment. Impact parameters of charged tracks were used to select enriched samples of b and light quark events, and reconstructed charmed mesons were used to select c quark events. We measured the charged multiplicities: nuds = 20.21 ± 0.10 (stat.) ± 0.22 (syst.), nc = 21.28 ± 0.46 (stat.)+0−04136 (syst.) and nb = 23.14 ± 0.10 (stat.)+0−03837 (syst.), from which we derived the differences between the total average charged multiplicities of c or b quark events and light quark events: ∆nc = 1.07 ± 0.47 (stat.)+0−03630 (syst.) and ∆nb = 2.93 ± 0.14 (stat.)+0−03029 (syst.). We compared these measurements with those at lower center-of-mass energies and with perturbative QCD predictions. These combined results are in agreement with the QCD expectations and disfavor the hypothesis of flavor-independent fragmentation.

Abstract

We present the first study of rapidity gaps in e+e- annihilations using Z0 decays collected by the SLD experiment at SLAC. Our measured rapidity gap spectra fall exponentially with increasing gap size over five decades, and we observe no anomalous class of events containing large gaps. This supports the interpretation of the large-gap events measured in pp and ep collisions in terms of exchange of color-singlet objects. The presence of heavy flavors or additional jets does not affect these conclusions.

Abstract

We present a comparison of the strong couplings of light (u, d, and s), c, and b quarks determined from multijet rates in flavor-tagged samples of hadronic Z0 decays recorded with the SLC Large Detector at the SLAC Linear Collider. Flavor separation on the basis of lifetime and decay multiplicity differences among hadrons containing light, c, and b quarks was made using the SLD precision tracking system. We find (formula presented).

Abstract

We present the first experimental study of the ratio of cumulant to factorial moments of the charged-particle multiplicity distribution in high-energy particle interactions, using hadronic Z0 decays collected by the SLD experiment at SLAC. We find that this ratio, as a function of the moment-rank q, decreases sharply to a negative minimum at q - 5, which is followed by quasi-oscillations. These features are insensitive to experimental systematic effects and are in qualitative agreement with expectations from next-to-next-to-leading-order perturbative QCD.

Abstract

The parity-violating parameters Ab and Ac are directly measured by the SLD experiment at the SLAC Linear Collider in e+e- collisions with polarized electrons at the Z0 resonance. Leptons with distinctive total and transverse momenta are used to select and analyze Z0→bb̄ and Z0→cc̄ events. Ab and Ac 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 pb-1 of Z0 decay data with an average electron beam polarization of 63% we find Ab=0.91±0.14 (stat) ± 0.07 (syst) and Ac=0.37±0.23 (stat) ± 0.21 (syst).

Abstract

We present a direct measurement of Ac=2vcac(vc2+ac2) from the left-right forward-backward asymmetry of D*+ and D+ mesons in Z0 events produced with the longitudinally polarized SLAC Linear Collider beam. These Z0→cc̄ events are tagged on the basis of event kinematics and decay topology from a sample of hadronic Z0 decays recorded by the SLAC Large Detector. We measure Ac0=0.73±0.22(stat)±0.10(syst).

Abstract

We present the first measurement of the correlation between the Z0 spin and the event-plane orientation in polarized Z0 decays into three jets in the SLAC Linear Collider Large Detector experiment at SLAC utilizing a longitudinally polarized electron beam. The CP-even and T-odd triple product SZ(k1×k2), formed from the two fastest jet momenta k1 and k2 and the Z0 polarization vector SZ, 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 -0.022<0.039 on the correlation.

Abstract

We report a measurement of the average 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 B hadron lifetime information in a sample of 50 × 103 Z0 decays. A lifetime of 1.564 ± 0.030(stat) ± 0.036(syst) ps was extracted from the decay length distribution of these vertices using a binned maximum likelihood method.

Abstract

Using an impact parameter tag to select an enriched sample of Z0→bb̄ events, and the net momentum-weighted track charge to identify the sign of the charge of the underlying b quark, we have measured the left-right forward-backward asymmetry for b quark production as a function of polar angle. Based on 1.8 pb-1 of Z0 decay data produced with a mean electron beam polarization of Pe=63%, this yields a direct measurement of the extent of parity violation in the Zbb coupling of Ab=0.87±0.11(stat)±0. 09(syst).

Abstract

We have searched for signatures of polarization in hadronic jets from Z0→qq̄ 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 et al.

Abstract

The parity violation parameters Ab and Ac of the Zbb¯ and Zcc¯ 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 Čerenkov Ring Imaging Detector. Based on the 1993–1995 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

Using an impact parameter tag to select an enriched sample of Z0→bb̄ events, we have measured the difference between the average charged multiplicity of Z0→bb̄ and Z0→ hadrons to be n̄b-n̄had=2.24±0.30 (stat) ±0.33 (syst) tracks per event. From this, we have derived n̄b-n̄uds=3.31±0.41±0. 79. Comparing this measurement with those at lower center-of-mass energies, we find no evidence that n̄b-n̄uds 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 Mb2.

Abstract

We present the first measurement of the left-right cross-section asymmetry (A(LR)) 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 A(LR) to be 0.100 +/- 0.044 (stat.) +/- 0.004 (syst.), which determines the effective weak mixing angle to be sin2 theta(W)eff = 0.2378 +/- 0.0056 (stat.) +/- 0.0005 (syst.).

Abstract

We present the first measurement of the left-right charge asymmetry [Formula presented] in hadronic Z boson decays. This was performed at [Formula presented] with the SLD at the SLAC Linear Collider with a polarized electron beam. Using 89838 events, we obtain [Formula presented] which leads to a measurement of the electron left-right asymmetry parameter, [Formula presented], and [Formula presented]. Also, the [Formula presented] measurement combined with the left-right cross section asymmetry determines A_e independently of the value of the electron-beam polarization.

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, A0 LR, to be 0.1512 ± 0.0042(stat) ± 0.0011(syst), which is equivalent to an effective weak mixing angle of sin2θeff W=0.23100 ± 0.00054(stat) ± 0.00014(syst).

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 present the first study of rapidity gaps in e+e- annihilations using Z0 decays collected by the SLD experiment at SLAC. Our measured rapidity gap spectra fall exponentially with increasing gap size over five decades, and we observe no anomalous class of events containing large gaps. This supports the interpretation of the large-gap events measured in pp and ep collisions in terms of exchange of color-singlet objects. The presence of heavy flavors or additional jets does not affect these conclusions.
