Abstract: We have observed new channels for $\ensuremath{\tau}$ decays with an $\ensuremath{\eta}$ in the final state. We study 3-prong tau decays, using the $\ensuremath{\eta}\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}$ and $\ensuremath{\eta}\ensuremath{\rightarrow}3{\ensuremath{\pi}}^{0}$ decay modes and 1-prong decays with two ${\ensuremath{\pi}}^{0}$'s using the $\ensuremath{\eta}\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}$ channel. The measured branching fractions are $B({\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}\ensuremath{\eta}{\ensuremath{\nu}}_{\ensuremath{\tau}})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}({3.4}_{\ensuremath{-}0.5}^{+0.6}\ifmmode\pm\else\textpm\fi{}0.6)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$ and $B({\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}2{\ensuremath{\pi}}^{0}\ensuremath{\eta}{\ensuremath{\nu}}_{\ensuremath{\tau}})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}(1.4\ifmmode\pm\else\textpm\fi{}0.6\ifmmode\pm\else\textpm\fi{}0.3)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$. We observe clear evidence for ${f}_{1}\ensuremath{\rightarrow}\ensuremath{\eta}\ensuremath{\pi}\ensuremath{\pi}$ substructure and measure $B({\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{f}_{1}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\nu}}_{\ensuremath{\tau}})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}({5.8}_{\ensuremath{-}1.3}^{+1.4}\ifmmode\pm\else\textpm\fi{}1.8)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$. We have also searched for ${\ensuremath{\eta}}^{\ensuremath{'}}(958)$ production and obtain 90% C.L. upper limits $B({\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\eta}}^{\ensuremath{'}}{\ensuremath{\nu}}_{\ensuremath{\tau}})l7.4\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$ and $B({\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}{\ensuremath{\eta}}^{\ensuremath{'}}{\ensuremath{\nu}}_{\ensuremath{\tau}})l8.0\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$.

Abstract: Using the CLEO detector at the Cornell e{sup +}e{sup {minus}} storage ring CESR we study the two-photon production of {Lambda}{bar {Lambda}}, making the first observation of {gamma}{gamma}{r_arrow}{Lambda}{bar {Lambda}}. We present the cross section for {gamma}{gamma}{r_arrow}{Lambda}{bar {Lambda}} as a function of the {gamma}{gamma} center of mass energy and compare it to that predicted by the quark-diquark model. {copyright} {ital 1997} {ital The American Physical Society}

Abstract: Using e{sup +}e{sup {minus}} annihilation data collected by the CLEOII detector at CESR, we have observed the decay D{sup +}{sub s}{r_arrow}{omega}{pi}{sup +} . This final state may be produced through the annihilation decay of the D{sup +}{sub s} , or through final state interactions. We find a branching ratio of {Gamma}(D{sup +}{sub s}{r_arrow}{omega}{pi}{sup +})/{Gamma}(D{sup +}{sub s}{r_arrow} {eta}{pi}{sup +})=0.16{plus_minus}0.04{plus_minus}0 .03 , where the first error is statistical and the second is systematic. {copyright} {ital 1997} {ital The American Physical Society}

Abstract: We have searched for lepton flavor violating decays of the {tau} lepton using final states with an electron or a muon and one or two {pi}{sup 0} or {eta} mesons but no neutrinos. The data used in the search were collected with the CLEO II detector at the Cornell Electron Storage Ring (CESR) and correspond to an integrated luminosity of 4.68 fb{sup {minus}1} . No evidence for signals was found, resulting in much improved limits on the branching fractions for the one-meson modes and the first upper limits for the two-meson modes. {copyright} {ital 1997} {ital The American Physical Society}

Abstract: Using the CLEO-II data set we have searched for the Cabibbo-suppressed decays B{sup 0} {yields} D*{sup +}D*{sup -}. For the decay B{sup 0} {yields} D*{sup +}D*{sup -}, we observe one candidate signal event, with an expected background of 0.022 {+-} 0.011 events. This yield corresponds to a branching fraction of {Beta}(B{sup 0} {yields} D*{sup +}D*{sup -}) = (5.3{sub -3.7}{sup +7.1}(stat) {+-} 1.0(syst)) x 10{sup -4} and an upper limit of {Beta}(B{sup 0} {yields} D*{sup +}D{sup -}) < 2.2 x 10{sup -3} at the 90% CL. For B{sup 0} {yields} D*{sup {+-}}D{sup {-+}} and B{sup 0} {yields} D{sup +}D{sup -}, no significant excess of signal above the expected background level is seen, and we calculate the 90% CL upper limits on the branching fractions to be {Beta}(B{sup 0} {yields} D*{sup {+-}}D{sup {-+}}) < 1.8 x 10{sup -3} and B(B{sup 0} {yields} D{sup +}D{sup -}) < 1.2 x 10{sup -3}.

Abstract: We have searched for the decays $B\ensuremath{\rightarrow}\ensuremath{\mu}{\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}}\ensuremath{\gamma}$ and $B\ensuremath{\rightarrow}e{\overline{\ensuremath{\nu}}}_{e}\ensuremath{\gamma}$ in a sample of $2.7\ifmmode\times\else\texttimes\fi{}{10}^{6}$ charged $B$ decays collected with the CLEO II detector. In the muon channel, we observe no candidates in the signal region and set an upper limit on the branching fraction of $\mathcal{B}(B\ensuremath{\rightarrow}\ensuremath{\mu}{\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}}\ensuremath{\gamma})l5.2\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$ at the 90% confidence level. In the electron channel, we observe five candidates in the signal region and set an upper limit on the branching fraction of $\mathcal{B}(B\ensuremath{\rightarrow}e{\overline{\ensuremath{\nu}}}_{e}\ensuremath{\gamma})l2.0\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$ at the 90% confidence level.

Abstract: We have measured the spectral shape Michel parameters ρ and η using leptonic decays of the τ, recorded by the CLEO II detector. Assuming e-μ universality in the vectorlike couplings, we find ρeμ = 0.735 ± 0.013 ± 0.008 and ηeμ = -0.015 ± 0.061 ± 0.062, where the first error is statistical and the second systematic. We also present measurements for the parameters for e and μ final states separately.

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: Using data taken with the CLEO II detector at the Cornell Electron Storage Ring, we have determined the ratio of branching fractions: ${R}_{\ensuremath{\gamma}}\ensuremath{\equiv}\ensuremath{\Gamma}(\ensuremath{\Upsilon}(1S)\ensuremath{\rightarrow}\ensuremath{\gamma}\mathrm{gg})/\ensuremath{\Gamma}(\ensuremath{\Upsilon}(1S)\ensuremath{\rightarrow}\mathrm{ggg})=[2.75\ifmmode\pm\else\textpm\fi{}0.04(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.15(\mathrm{syst})]%$. From this ratio, we have determined the QCD scale parameter ${\ensuremath{\Lambda}}_{\overline{\mathrm{MS}}}$ (defined in the modified minimal subtraction scheme) to be ${\ensuremath{\Lambda}}_{\overline{\mathrm{MS}}}=233\ifmmode\pm\else\textpm\fi{}11\ifmmode\pm\else\textpm\fi{}59$ MeV, from which we determine a value for the strong coupling constant ${\ensuremath{\alpha}}_{s}{(M}_{\ensuremath{\Upsilon}(1S)})=0.163\ifmmode\pm\else\textpm\fi{}0.002\ifmmode\pm\else\textpm\fi{}0.014$, or ${\ensuremath{\alpha}}_{s}{(M}_{Z})=0.110\ifmmode\pm\else\textpm\fi{}0.001\ifmmode\pm\else\textpm\fi{}0.007$.

Abstract: Using data recorded by the CLEO-II detector at CESR, we report evidence of a pair of excited charmed baryons, one decaying into {Lambda}{sup +}{sub c}{pi}{sup +} and the other into {Lambda}{sup +}{sub c}{pi}{sup -}. The doubly charged state has a measured mass difference M({Lambda}{sup +}{sub c}{pi}{sup +}) -M({Lambda}{sup +}{sub c}) of 234.5{plus_minus}1.1{plus_minus}0.8 MeV/c{sup 2} and a width of 17.9{sup +3.8}{sub -3.2}{plus_minus}4.0MeV/c{sup 2}, and the neutral state has a measured mass difference M({Lambda}{sup +}{sub c}{pi}{sup -}) -M({Lambda}{sup +}{sub c}) of 232.6{plus_minus}1.0{plus_minus}0.8 MeV/c{sup 2} and a width of 13.0{sup +3.7}{sub -3.0}{plus_minus}4.0MeV/c{sup 2}. We interpret these data as evidence of the {Sigma}{sup *++}{sub c} and {Sigma}{sup *0}{sub c}, the spin (3)/(2){sup +} excitations of the {Sigma}{sub c} baryons. {copyright} {ital 1997} {ital The American Physical Society}

Abstract: Using data collected on the $\ensuremath{\Upsilon}(4S)$ resonance and the nearby continuum by the CLEO-II detector, we have studied combinations of baryons with leptons produced in the process $\ensuremath{\Upsilon}(4S)\ensuremath{\rightarrow}B\overline{B}$, $B\ensuremath{\rightarrow}\mathrm{lepton}+X$, $\overline{B}\ensuremath{\rightarrow}\mathrm{baryon}+X$. Our results do not support models which attribute the bulk of ${\ensuremath{\Lambda}}_{c}$ production in $\overline{B}$ decay to the process $b\ensuremath{\rightarrow}{\mathrm{cW}}^{\ensuremath{-}}{,W}^{\ensuremath{-}}\ensuremath{\rightarrow}\overline{c}s$.

Abstract: CLEO has studied $B$ decays to $\ensuremath{\pi}\ensuremath{\ell}\ensuremath{\nu}$, $\ensuremath{\rho}\ensuremath{\ell}\ensuremath{\nu}$, and $\ensuremath{\omega}\ensuremath{\ell}\ensuremath{\nu}$, where $\ensuremath{\ell}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}eor\ensuremath{\mu}$, by incorporating the missing momentum into full $B$ reconstruction. With the ${B}^{0}$ and ${B}^{+}$ modes combined according to isospin predictions for the relative partial widths, we obtain $B({B}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\ell}}^{+}\ensuremath{\nu})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}(1.8\ifmmode\pm\else\textpm\fi{}0.4\ifmmode\pm\else\textpm\fi{}0.3\ifmmode\pm\else\textpm\fi{}0.2)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$ and $B({B}^{0}\ensuremath{\rightarrow}{\ensuremath{\rho}}^{\ensuremath{-}}{\ensuremath{\ell}}^{+}\ensuremath{\nu})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}(2.5\ifmmode\pm\else\textpm\fi{}{0.4}_{\ensuremath{-}0.7}^{+0.5}\ifmmode\pm\else\textpm\fi{}0.5)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$, where the errors are statistical, systematic, and the estimated model dependence. We also estimate $|{V}_{\mathrm{ub}}|\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}(3.3\ifmmode\pm\else\textpm\fi{}{0.2}_{\ensuremath{-}0.4}^{+0.3}\ifmmode\pm\else\textpm\fi{}0.7)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}3}$.

Abstract: We use data collected by the CLEO II detector at the Cornell Electron Storage Ring (CESR) to search for B{sup +} {yields} h{sup +}h{sup -}h{sup +} (non-resonant) decays, where h{sup {+-}} can be either {pi}{sup {+-}}, K{sup {+-}} or p({bar p}). We see no evidence for signals and set upper limits on the branching fractions in the range (2.8 - 8.9) x 10{sup -5}. If observed, these decays may display CP violating asymmetries.

Abstract: Using the angular correlation between the ${\ensuremath{\pi}}^{+}$ emitted in a ${D}^{*+}\ensuremath{\rightarrow}{D}^{0}{\ensuremath{\pi}}^{+}$ decay and the ${e}^{+}$ emitted in the subsequent ${D}^{0}\ensuremath{\rightarrow}X{e}^{+}\ensuremath{\nu}$ decay, we have measured the branching fraction for the inclusive semielectronic decay of the ${D}^{0}$ meson to be $\mathcal{B}({D}^{0}\ensuremath{\rightarrow}X{e}^{+}\ensuremath{\nu})=[6.64\ifmmode\pm\else\textpm\fi{}0.18(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.29(\mathrm{syst})]%$. The measurement uses 1.7 ${\mathrm{fb}}^{\ensuremath{-}1}$ of ${e}^{+}{e}^{\ensuremath{-}}$ collisions recorded by the CLEO II detector located at the Cornell Electron Storage Ring (CESR). Combining this result with previous CLEO results we find $\frac{\mathcal{B}({D}^{0}\ensuremath{\rightarrow}X{e}^{+}\ensuremath{\nu})}{\mathcal{B}({D}^{0}\ensuremath{\rightarrow}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+})}=1.684\ifmmode\pm\else\textpm\fi{}0.056(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.093(\mathrm{syst})$ and $\frac{\mathcal{B}({D}^{0}\ensuremath{\rightarrow}{K}^{\ensuremath{-}}{e}^{+}\ensuremath{\nu})}{\mathcal{B}({D}^{0}\ensuremath{\rightarrow}X{e}^{+}\ensuremath{\nu})}=0.581\ifmmode\pm\else\textpm\fi{}0.023(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.028(\mathrm{syst})$. The difference between this inclusive rate and the sum of the measured exclusive branching fractions (measured at CLEO and other experiments) is also presented.

Abstract: Using data recorded by the CLEO-II detector at CESR, they report the first observation of an excited charmed baryon decaying into {Xi}{sub c}{sup 0}{pi}{sup +}. The state has mass difference M({Xi}{sub c}{sup 0}{pi}{sup +}) = M({Xi}{sub c}{sup 0}) of 174.3 {+-} 0.5 {+-} 1.0 MeV/c{sup 2}, and a width of < 3.1 MeV/c{sup 2} (90% confidence level limit). They identify the new state as the {Xi}*{sub c}{sup +}, the isospin partner of the recently discovered {Xi}*{sub c}{sup 0}.

Abstract: We present a model-independent measurement of B(D s − → Φπ − ) B(D 0 → K − π + ) by partially reconstructing the decay B 0 → D ∗+ D s ∗− . Using data collected with the CLEO II detector at CESR, we determine B(D s − → Φπ − ) B(D 0 → K − π + ) = 0.92 ± 0.20 (stat.) ± 0.11(syst.) . Our measurement of B ( D 0 → K − π + ) then gives B ( D s − → Φπ − ) = (3.59 ± 0.77 ± 0.48)%.

Abstract: The decay {tau}{sup -} {yields} K{sup -} {eta}{nu}{sub {tau}} has been observed with the CLEO II detector. The {eta} meson is reconstructed using two decay channels, {eta} {yields} {gamma}{gamma} and {pi}{sup +}{pi}{sup -}{pi}{sup 0}. The measured branching fraction is B({tau}{sup -} {yields} K{sup -}{eta}{nu}{sub {tau}}) = (2.6 {+-} 0.5 {+-} 0.5) x 10{sup -4}, somewhat higher than the theoretical estimates. An improved upper limit for the second-class-current decay {tau}{sup -} {yields} {pi}{sup -}{eta}{nu}{sub {tau}} is set, B({tau}{sup -} {yields} {pi}{sup -}{eta}{nu}{sub {tau}}) < 1.4 x 10{sup -4} at 95% CL, consistent with the theoretical expectations.

Abstract: Using a sample of $2.6\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $\ensuremath{\Upsilon}(4\mathrm{S})\ensuremath{\rightarrow}B\overline{B}$ events collected with the CLEO II detector at the Cornell Electron Storage Ring, we have measured the form factors for ${\overline{B}}^{0}\ensuremath{\rightarrow}{D}^{*+}{\ensuremath{\ell}}^{\ensuremath{-}}\overline{\ensuremath{\nu}}$. We perform a three-parameter fit with the joint distribution of four kinematic variables to obtain the form-factor ratios ${R}_{1}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.18\ifmmode\pm\else\textpm\fi{}0.30\ifmmode\pm\else\textpm\fi{}0.12$ and ${R}_{2}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.71\ifmmode\pm\else\textpm\fi{}0.22\ifmmode\pm\else\textpm\fi{}0.07,$ and the form-factor slope ${\ensuremath{\rho}}_{{A}_{1}}^{2}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.91\ifmmode\pm\else\textpm\fi{}0.15\ifmmode\pm\else\textpm\fi{}0.06,$ which is closely related to the slope of the Isgur-Wise function. The form-factor ratios are consistent with predicted corrections to the heavy-quark symmetry limit ${R}_{1}{\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}R}_{2}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1$.

Abstract: This paper describes new measurements from CLEO of the inclusive B\ensuremath{\rightarrow}${\mathit{D}}_{\mathit{s}}^{+}$X branching fraction as well as the ${\mathit{B}}^{+}$\ensuremath{\rightarrow}${\mathit{D}}_{\mathit{s}}^{(\mathrm{*})+}$D${\mathrm{\ifmmode\bar\else\textasciimacron\fi{}}}^{(\mathrm{*})0}$ and ${\mathit{B}}^{0}$\ensuremath{\rightarrow}${\mathit{D}}_{\mathit{s}}^{(\mathrm{*})+}$${\mathit{D}}^{(\mathrm{*})\mathrm{\ensuremath{-}}}$ branching fractions. The inclusive branching fraction is B(B\ensuremath{\rightarrow}${\mathit{D}}_{\mathit{s}}^{+}$X)=(12.11\ifmmode\pm\else\textpm\fi{}0.39\ifmmode\pm\else\textpm\fi{}0.88\ifmmode\pm\else\textpm\fi{}1.38)% where the first error is statistical, the second is the systematic error, and the third is the error due to the uncertainty in the ${\mathit{D}}_{\mathit{s}}^{+}$\ensuremath{\rightarrow}\ensuremath{\varphi}${\mathrm{\ensuremath{\pi}}}^{+}$ branching fraction. The branching fractions for the B\ensuremath{\rightarrow}${\mathit{D}}_{\mathit{s}}^{(\mathrm{*})+}$D${\mathrm{\ifmmode\bar\else\textasciimacron\fi{}}}^{(\mathrm{*})}$ modes are found to be between 0.9% and 2.4% and are significantly more precise than previous measurements. The sum of the B\ensuremath{\rightarrow}${\mathit{D}}_{\mathit{s}}^{(\mathrm{*})+}$D${\mathrm{\ifmmode\bar\else\textasciimacron\fi{}}}^{(\mathrm{*})}$ branching fractions is consistent with the results of fits to the inclusive ${\mathit{D}}_{\mathit{s}}^{+}$ momentum spectrum. Factorization is used to arrive at a value for ${\mathit{f}}_{{\mathit{D}}_{\mathit{s}}}$, the ${\mathit{D}}_{\mathit{s}}^{+}$ decay constant. \textcopyright{} 1996 The American Physical Society.

Abstract: Using the CLEO II detector at the Cornell Electron Storage Ring, we have searched for flavor changing neutral currents and lepton family number violations in D^0 meson decays. The upper limits on the branching fractions for D^0→l^+l^- and D^0→X^0l^+l^- are in the range 10^(-5) to 10^(-4), where X^0 can be a π^0, K_s^0, η, ρ^0, ω, K^(*0), or φ meson, and the l^+l^- pair can be e^+e^-, μ^+μ^-, or e^±μ^∓. Although these limits are above the theoretical predictions, most are new or an order of magnitude lower than previous limits.

Abstract: Using the CLEO II detector operating at the e + e − Cornell Electron Storage Ring (CESR), we present evidence for new decay modes of the Ξ c + into Ξ 0 π + , Ξ 0 π + π 0 , and Ξ 0 π + π − π + . The branching ratios of these decay modes, relative to Ξ c + → Ξ − π + π + , have been measured to be 0.55±0.13±0.09, 2.34±0.57±0.37, and 1.74±0.42±0.27, respectively.

Abstract: We have used the CLEO II detector and 2.06fb^(-1) of ϒ(4S) data to measure the B-meson semileptonic branching fraction. The B→Xeν momentum spectrum was obtained over nearly the full momentum range by using charge and kinematic correlations in events with a high-momentum lepton tag and an additional electron. We find B(B→Xeν) = (10.49±0.17±0.43)%, with overall systematic uncertainties less than those of untagged single-lepton measurements. We use this result to calculate the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element V_(cb) and to set an upper limit on the fraction of ϒ(4S) decays to final states other than BB .

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 have studied the Cabibbo suppressed and color suppressed two-body decays B to ψϱ (ψω or ψa 1 ). Using a data sample of 5.12 million B decays collected with the CLEO II detector we find the 90% confidence level upper limits for branching fractions of B 0 → ψϱ 0 and B 0 → ψω to be 2.5 · 10 −4 and 2.7 · 10 −4 , respectively. We also update the branching fraction B − → ψπ − to be (5.6 ± 2.7) · 10 −5 .

The latter mode, observed for the first time with significant statistics, is of interest as a test of color suppression in charm decays. We have determined the branching ratios for these modes relative to {Lambda}{sub {ital c}}{sup +}{r_arrow}{ital pK{sup {minus}}}{pi}{sup +} and compared our results with theory. {copyright} {ital 1996 The American Physical Society.}

Abstract: Using the CLEO II detector we measure B(D s + Ⅵηe + ν)/B(D s + Ⅵφe + ν)=1.24±0.12±0.15, B(D s + Ⅵη ′ e + ν)/B(D s + Ⅵφe + ν)=0.43±0.11±0.07, and B(D s + Ⅵη ′ e + ν)/B(D s + Ⅵηe + ν)=0.35±0.09±0.07. We find the ratio of vector to pseudoscalar final states, B(D s + Ⅵφe + ν)/B(D s + Ⅵ(η+η ′ )e + ν)=0.60±0.06±0.06, which is similar to the ratio found in nonstrange D decays.

Abstract: We present measurements of spectral moments extracted from the invariant mass distributions of the final states of hadronic τ decay products recorded in the CLEO detector. From a fit of theoretical predictions to the measurements of spectral moments and the total hadronic decay width of the τ, we determine the strong coupling constant and a set of non-perturbative QCD parameters. The strong coupling constant is measured to be α s ( m τ ) = 0.306 ± 0.024, which when extrapolated to the Z mass, yields α s ( M z ) = 0.114 ± 0.003.

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 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 results on energy resolution and linearity, and position resolution, from a test of an array of CsI(T1) crystals in a π/e/μ beam (120 to 400 MeV) at TRIUMF. The crystal array was designed to study the effects of longitudinal and transverse crystal segmentation on energy and position resolution and background rejection. We also studied the feasibility of a wavelength-shifter and multi-photodiode readout system, suitable for use in magnetic detectors at low and medium energy, high-luminosity e+e− storage rings. Energy resolutions of (1.69±0.08)% √E( GeV ) and (1.83±0.05)% √E( GeV ) were obtained for two different crystal tower configurations. Position resolution of 6.5 (9.0) mm was obtained at 300 (120) MeV for a 2 × 2 square array of four 4 × 4 × 7.4 cm3 crystals transverse to the beam.

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).
