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

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 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

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 $\sin^2\theta_W^{\rm {eff}} = 0.2378\pm 0.0056\, ({\rm stat.})\pm 0.0005\, ({\rm syst.})$.
