3. Pedagogical dialogues with 2 year olds in 'preschool' settings: What do they look like?

Abstract: This article reports on a project midway through a 2-year investigation of the pedagogical interactions that take place for 2 year olds in mixed-age early childhood education (ECE) settings. Teachers slowed down and scrutinised their practice by videoing, analysing, and theorising their dialogue with and about 2 year olds as a central form of teaching and learning. The primary aim of the project was to make explicit the nature of 2 year olds' dialogue in ECE settings traditionally oriented to 3 to 4 year olds. Fine-tuned coding of dialogue and their interpreted meanings by the teachers highlight the impact of different events in the ECE setting on the nature of dialogue that takes place and identified 12 different genre in which 2 year olds were found to engage (or disengage). The insights generated from this project support teachers to re-vision their pedagogy in ways that are inclusive of the specialised genre of this younger age group, and celebrate the many pedagogical provocations for dialogue in preschool settings.

Abstract: We present the first measurement of the Michel parameters η ‾ and ξκ in the radiative leptonic decay of the τ lepton using 703 fb-1 of data collected with the Belle detector at the KEKB e + e − collider. The Michel parameters are measured by an unbinned maximum likelihood fit to the kinematic information of e + e − → τ + τ − → ( π + π 0 ν ‾ ) ( l − ν ν ‾ γ ) ( l = e or μ ) . The preliminary values of the measured Michel parameters are η ‾ = − 2.0 ± 1.5 ± 0.8 and ξ κ = 0.6 ± 0.4 ± 0.2 , where the first error is statistical and the second is systematic.

Abstract: Summary A series of species trials were set up to investigate the establishment and early growth (up to 14 years old) of 44 native and non-native tree species on a variety of different site types in lowland Britain. On good quality lowland afforestation sites, Platanus x hispanica (London plane) established and grew more successfully than the native trees tested, and may be an example of a species that could theoretically be established in anticipation of future climate change. Experiments on a variety of community woodland sites indicated that a range of exotic species, such as X Cupressocyparis leylandii (Leyland cypress), may have the potential for establishing a woodland cover on poorly restored land where few other trees would grow. However, on less challenging, better restored sites, a wide range of native species also grew successfully. Further long-term and larger scale trials on a wider variety of sites are required to confi rm the potential of the species tested for British conditions. The results from these experiments also showed that relative growth rates of different species can vary through time, highlighting the danger in making premature judgements about species suitability based solely on very early tree growth.

8. Induction of LFA-1-Dependent Neutrophil Rolling on ICAM-1 by Engagement of E-Selectin

Abstract: To study rolling of mouse neutrophils on E-selectin and ICAM-1 in an ex vivo flow chamber system.The authors developed a small autoperfused flow chamber (20 x 200-microm cross section) that allows direct visualization of cells with and without fluorescent labeling and does not require recirculation of blood.Neutrophils rolled on E-selectin alone, but were unable to interact with immobilized ICAM-1. When ICAM-1 was co-immobilized with E-selectin, the number of cells that rolled was doubled, but no significant firm adhesion was observed. This phenomenon was specific for E-selectin, and no enhancement of rolling was observed when P-selectin was immobilized with ICAM-1. The increased neutrophil rolling seen on E-selectin and ICAM-1 substrates required beta2 integrins. Treating mice with antibodies to the beta2 integrins LFA-1 and Mac-1 showed that LFA-1 was primarily responsible for mediating rolling on ICAM-1 in this model. Increased rolling on E-selectin and ICAM-1 was significantly reduced following administration of a specific p38 mitogen-activated protein kinase (MAPK) inhibitor.The data show that neutrophil rolling on E-selectin leads to partial activation of LFA-1, enabling LFA-1-dependent rolling on ICAM-1. This mechanism is likely to amplify and accelerate neutrophil recruitment in inflammation.

Abstract: Using a sample of $25.9\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $\ensuremath{\psi}(2S)$ decays acquired with the CLEO-c detector at the CESR ${e}^{+}{e}^{\ensuremath{-}}$ collider, we report branching fractions for the decays ${\ensuremath{\chi}}_{cJ}\ensuremath{\rightarrow}p\overline{p}{\ensuremath{\pi}}^{0}$, $p\overline{p}\ensuremath{\eta}$, and $p\overline{p}\ensuremath{\omega}$, with $J=0$, 1, 2. Our results for $\mathcal{B}({\ensuremath{\chi}}_{cJ}\ensuremath{\rightarrow}p\overline{p}{\ensuremath{\pi}}^{0})$ and $\mathcal{B}({\ensuremath{\chi}}_{cJ}\ensuremath{\rightarrow}p\overline{p}\ensuremath{\eta})$ are consistent with, but more precise than, previous measurements. Furthermore, we include the first measurement of $\mathcal{B}({\ensuremath{\chi}}_{cJ}\ensuremath{\rightarrow}p\overline{p}\ensuremath{\omega})$.

Abstract: Using a large sample ({approx_equal}11800 events) of D{sup +{yields}}K{sup -{pi}+}e{sup +{nu}}{sub e} and D{sup +{yields}}K{sup -{pi}+{mu}+{nu}}{sub {mu}}decays collected by the CLEO-c detector running at the {psi}(3770), we measure the helicity basis form factors free from the assumptions of spectroscopic pole dominance and provide new, accurate measurements of the absolute branching fractions for D{sup +{yields}}K*{sup 0}e{sup +{nu}}{sub e} and D{sup +{yields}}K*{sup 0{mu}+{nu}}{sub {mu}}decays. We find branching fractions which are consistent with previous world averages. Our measured helicity basis form factors are consistent with the spectroscopic pole dominance predictions for the three main helicity basis form factors describing D{sup +{yields}}K*{sup 0}l{sup +{nu}}{sub l} decay. The ability to analyze D{sup +{yields}}K{sup -{pi}+{mu}+{nu}}{sub {mu}}allows us to make the first nonparametric measurements of the mass-suppressed form factor. Our result is inconsistent with existing lattice QCD calculations. Finally, we measure the form factor that controls nonresonant s-wave interference with the D{sup +{yields}}K*{sup 0}l{sup +{nu}}{sub l} amplitude and search for evidence of possible additional nonresonant d- or f-wave interference with the K*{sup 0}.

Abstract: A search for J/{psi} radiative decay to weakly interacting neutral final states was performed using the CLEO-c detector at the Cornell Electron Storage Ring. J/{psi} events were selected by observing the hadronic decay {psi}(2S){yields}{pi}{sup +{pi}-}J/{psi}. A total of 3.7x10{sup 6} J/{psi} events were used to study the decay J/{psi}{yields}{gamma}+X, where X is a narrow state that is invisible to the detector. No significant signal was observed, and upper limits on the branching fraction were set for masses m{sub X} up to 960 MeV/c{sup 2}. The upper limit corresponding to m{sub X}=0 is 4.3x10{sup -6} at the 90% confidence level.

Abstract: We have measured the inclusive semileptonic branching fractions of $D^0$, $D^+$, and $D^+_s$ mesons. For these measurements, we have used the full CLEO-c open-charm data samples, 818 pb$^{-1}$ at $E_\text{CM} = 3.774$ GeV, giving $D^0 \bar{D}^0$ and $D^+ D^-$ events, and 602 pb$^{-1}$ at $E_\text{CM} = 4.170$ GeV, giving $D^{\ast \pm}_s D^\mp_s$ events. We obtain $\mathcal{B}(D^0 \to X e^+ \nu_e) = (6.46 \pm 0.09 \pm 0.11)$%, $\mathcal{B}(D^+ \to X e^+ \nu_e) = (16.13 \pm 0.10 \pm 0.29)$%, and $\mathcal{B}(D^+_s \to X e^+ \nu_e) = (6.52 \pm 0.39 \pm 0.15)$%, where the first uncertainties are statistical and the second are systematic. From these and lifetimes obtained elsewhere, we obtain the ratios of semileptonic decay widths $\Gamma (D^+ \to X e^+ \nu_e) / \Gamma (D^0 \to X e^+ \nu_e) = 0.985 \pm 0.015 \pm 0.024$ and $\Gamma (D^+_s \to X e^+ \nu_e) / \Gamma (D^0 \to X e^+ \nu_e) = 0.828 \pm 0.051 \pm 0.025$. The ratio of $D^+$ and $D^0$ is consistent with the isospin symmetry prediction of unity, and the ratio of $D^+_s$ and $D^0$ differs from unity, as expected., Comment: 16 pages, available through http://www.lns.cornell.edu/public/CLNS/, published in Physical Review D Vol.81, No.5 (2010).

No signals are observed in any of the 11 exclusive ${\ensuremath{\eta}}_{c}(2S)$ decay modes studied, or in their sum. Product branching fraction upper limits are determined as a function of $\ensuremath{\Gamma}[{\ensuremath{\eta}}_{c}(2S)]$ for the 11 individual modes.

17. Ornamental uses of willow in Britain

Subjects: Artificial environment, Horticulture, Willow, biology, Agroforestry, Amenity, Ornamental plant, General Medicine, Business, biology.organism_classification, Natural (archaeology)
Abstract: SynopsisThe ornamental use of Salix in Britain must be measured against any detrimental impact introduced plants may have on the natural or artificial environment. Willows in amenity planting have the capacity to be both rewarding and at the same time damaging. Anyone using them should be aware of the constraints that may be imposed by the plants and by any potential site. Existing published plant lists are long and inaccurate, often failing to give proper advice on ornamental use. Commercial plant supply may be wanting. Forty species and cultivars are recommended here for a range of situations, but some require further taxonomic research and others need wider introduction to the trade.

Abstract: Analyzing 600 pb{sup -1} of e{sup +}e{sup -} collisions at 4170 MeV center-of-mass energy with the CLEO-c detector, we measure the branching fraction B(D{sub s}{sup +}{yields}{tau}{sup +}{nu})=(5.52{+-}0.57{+-}0.21)% using the {tau}{sup +}{yields}{rho}{sup +}{nu} decay mode. Combining with other CLEO measurements of B(D{sub s}{sup +}{yields}{tau}{sup +}{nu}) we determine the pseudoscalar decay constant f{sub D{sub s}}=(259.7{+-}7.8{+-}3.4) MeV consistent with the value obtained from our D{sub s}{sup +}{yields}{mu}{sup +}{nu} measurement of (257.6{+-}10.3{+-}4.3) MeV. Combining these measurements we find a value of f{sub D{sub s}}=(259.0{+-}6.2{+-}3.0) MeV, that differs from the most accurate prediction based on unquenched lattice gauge theory of (241{+-}3) MeV by 2.4 standard deviations. We also present the first measurements of B(D{sub s}{sup +}{yields}K{sup 0}{pi}{sup +}{pi}{sup 0})=(1.00{+-}0.18{+-}0.04)%, and B(D{sub s}{sup +}{yields}{pi}{sup +}{pi}{sup 0}{pi}{sup 0})=(0.65{+-}0.13{+-}0.03)%, and measure a new value for B(D{sub s}{sup +}{yields}{eta}{rho}{sup +})=(8.9{+-}0.6{+-}0.5)%.

Abstract: Using e{sup +}e{sup -} collision data taken with the CLEO-c detector at the Cornell Electron Storage Ring, we have investigated the direct photon spectrum in the decay {psi}(2S){yields}{gamma}gg. We determine the ratio of the inclusive direct photon decay rate to that of the dominant three-gluon decay rate {psi}(2S){yields}ggg (R{sub {gamma}}{identical_to}{gamma}({gamma}gg)/{gamma}(ggg)) to be R{sub {gamma}}(z{sub {gamma}}>0.4)=0.070{+-}0.002{+-}0.019{+-}0.011, with z{sub {gamma}} defined as the scaled photon energy relative to the beam energy. The errors shown are statistical, systematic, and that due to the uncertainty in the input branching fractions used to extract the ratio, respectively.

Abstract: Using the CLEO-c detector at the Cornell Electron Storage Ring, we have measured inclusive and exclusive cross sections for the production of ${D}^{+}$, ${D}^{0}$ and ${D}_{s}^{+}$ mesons in ${e}^{+}{e}^{\ensuremath{-}}$ annihilations at 13 center-of-mass energies between 3.97 and 4.26 GeV. Exclusive cross sections are presented for final states consisting of two charm mesons ($D\overline{D}$, ${D}^{*}\overline{D}$, ${D}^{*}{\overline{D}}^{*}$, ${D}_{s}^{+}{D}_{s}^{\ensuremath{-}}$, ${D}_{s}^{*+}{D}_{s}^{\ensuremath{-}}$, and ${D}_{s}^{*+}{D}_{s}^{*\ensuremath{-}}$) and for processes in which the charm-meson pair is accompanied by a pion. No enhancement in any final state is observed at the energy of the $Y(4260)$.

Abstract: Using ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}_{s}^{\ensuremath{-}}{D}_{s}^{*+}$ and ${D}_{s}^{*\ensuremath{-}}{D}_{s}^{+}$ interactions at 4170 MeV collected with the CLEO-c detector, we investigate the semileptonic decays ${D}_{s}^{+}\ensuremath{\rightarrow}{f}_{0}(980){e}^{+}\ensuremath{\nu}$ and ${D}_{s}^{+}\ensuremath{\rightarrow}\ensuremath{\phi}{e}^{+}\ensuremath{\nu}$. By examining the decay rates as functions of the four-momentum transfer squared ${q}^{2}$, we measure the ratio $[\frac{d\mathcal{B}}{d{q}^{2}}({D}_{s}^{+}\ensuremath{\rightarrow}{f}_{0}(980){e}^{+}\ensuremath{\nu})\mathcal{B}({f}_{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}})]/[\frac{d\mathcal{B}}{d{q}^{2}}({D}_{s}^{+}\ensuremath{\rightarrow}\ensuremath{\phi}{e}^{+}\ensuremath{\nu})\mathcal{B}(\ensuremath{\phi}\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}})]$ at ${q}^{2}$ of zero to be $(42\ifmmode\pm\else\textpm\fi{}11)%$. This ratio has been predicted to equal the rate ratio $[\mathcal{B}({B}_{s}\ensuremath{\rightarrow}J/\ensuremath{\psi}{f}_{0})\mathcal{B}({f}_{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}})]/[\mathcal{B}({B}_{s}\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\phi})\mathcal{B}(\ensuremath{\phi}\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}})]$, thus indicating that the $CP$ eigenstate $J/\ensuremath{\psi}{f}_{0}$ could be useful for measuring $CP$ violation via ${B}_{s}$ mixing. Assuming a simple pole model for the form factor $|{f}_{+}({q}^{2})|$ in the ${f}_{0}{e}^{+}\ensuremath{\nu}$ decay, we find a pole mass of $({1.7}_{\ensuremath{-}0.7}^{+4.5}\ifmmode\pm\else\textpm\fi{}0.2)\text{ }\text{ }\mathrm{GeV}$. We also determine the ${f}_{0}$ mass and width as $({977}_{\ensuremath{-}9}^{+11}\ifmmode\pm\else\textpm\fi{}1)$ and $({91}_{\ensuremath{-}22}^{+30}\ifmmode\pm\else\textpm\fi{}3)\text{ }\text{ }\mathrm{MeV}$, respectively. In addition, we present updated results for $\mathcal{B}({D}_{s}^{+}\ensuremath{\rightarrow}{f}_{0}(980){e}^{+}\ensuremath{\nu})\mathcal{B}({f}_{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}})=(0.20\ifmmode\pm\else\textpm\fi{}0.03\ifmmode\pm\else\textpm\fi{}0.01)%$ and $\mathcal{B}({D}_{s}^{+}\ensuremath{\rightarrow}\ensuremath{\phi}{e}^{+}\ensuremath{\nu})=(2.36\ifmmode\pm\else\textpm\fi{}0.23\ifmmode\pm\else\textpm\fi{}0.13)%$. Assuming that the ${f}_{0}$ wave function is a combination of strange and nonstrange quark-antiquark components, we use our measurement for $\mathcal{B}({D}_{s}^{+}\ensuremath{\rightarrow}{f}_{0}(980){e}^{+}\ensuremath{\nu})$ to extract a value of the mixing angle that we find consistent with $\ensuremath{\mid}\overline{s}s⟩$ dominance, adding to the mystery as to why the ${f}_{0}$ decays predominantly to two pions rather than two kaons.

Abstract: The first measurements of the coherence factors (R-K pi pi 0 and R-K3 pi) and the average strong-phase differences((delta(K pi pi 0)(D) and delta(K3 pi)(D))) for D-0 -> K- pi(+) pi(0) and D-0 -> K- pi(+) pi(+) pi(-) are presented. These parameters can be used to improve the determination of the unitarity triangle angle gamma in B- -> DK- decays, where D is a D-0 or (D) over bar (0) meson decaying to the same final state. The measurements are made using quantum-correlated, fully reconstructed D-0(D) over bar (0) pairs produced in e(+)e(-) collisions at the psi(3770) resonance. The measured values are: R-K pi pi 0 = 0.84 +/- 0.07, delta(K pi pi 0)(D) = (227(-17)(+14))degrees, R-K3 pi = 0.33(-0.23)(+0.20), and delta(K3 pi)(D) = (114(-23)(+26))degrees. These results indicate significant coherence in the decay D-0 -> K- pi(+) pi(0), whereas lower coherence is observed in the decay D-0 -> K- pi(+) pi(+) pi(-). The analysis also results in a small improvement in the knowledge of other D-meson parameters, in particular, the strong-phase difference for D-0 -> K- pi(+), delta(K pi)(D), and the mixing parameter y.

Abstract: Using the entire CLEO-c {psi}(3770){yields}DD event sample, corresponding to an integrated luminosity of 818 pb{sup -1} and approximately 5.4x10{sup 6} DD events, we present a study of the decays D{sup 0}{yields}{pi}{sup -}e{sup +}{nu}{sub e}, D{sup 0}{yields}K{sup -}e{sup +}{nu}{sub e}, D{sup +}{yields}{pi}{sup 0}e{sup +}{nu}{sub e}, and D{sup +}{yields}K{sup 0}e{sup +}{nu}{sub e}. Via a tagged analysis technique, in which one D is fully reconstructed in a hadronic mode, partial rates for semileptonic decays by the other D are measured in several q{sup 2} bins. We fit these rates using several form factor parametrizations and report the results, including form factor shape parameters and the branching fractions B(D{sup 0}{yields}{pi}{sup -}e{sup +}{nu}{sub e})=(0.288{+-}0.008{+-}0.003)%, B(D{sup 0}{yields}K{sup -}e{sup +}{nu}{sub e})=(3.50{+-}0.03{+-}0.04)%, B(D{sup +}{yields}{pi}{sup 0}e{sup +}{nu}{sub e})=(0.405{+-}0.016{+-}0.009)%, and B(D{sup +}{yields}K{sup 0}e{sup +}{nu}{sub e})=(8.83{+-}0.10{+-}0.20)%, where the first uncertainties are statistical and the second are systematic. Taking input from lattice quantum chromodynamics, we also find |V{sub cd}|=0.234{+-}0.007{+-}0.002{+-}0.025 and |V{sub cs}|=0.985{+-}0.009{+-}0.006{+-}0.103, where the third uncertainties are from lattice quantum chromodynamics.

Abstract: We exploit the quantum coherence between pair-produced ${D}^{0}$ and ${\overline{D}}^{0}$ in $\ensuremath{\psi}(3770)$ decays to make a first determination of the relative strong phase differences between ${D}^{0}\ensuremath{\rightarrow}{K}_{S}^{0}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ and ${\overline{D}}^{0}\ensuremath{\rightarrow}{K}_{S}^{0}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$, which are of great importance in determining the Cabibbo-Kobayashi-Maskawa angle $\ensuremath{\gamma}/{\ensuremath{\phi}}_{3}$ in ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}^{0}({\overline{D}}^{0}){K}^{\ensuremath{-}}$ decays. Using $818\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ of ${e}^{+}{e}^{\ensuremath{-}}$ collision data collected with the CLEO-c detector at ${E}_{\mathrm{cm}}=3.77\text{ }\text{ }\mathrm{GeV}$, we employ a binned Dalitz-plot analysis of ${K}_{S}^{0}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ and ${K}_{L}^{0}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ decays recoiling against flavor-tagged, $CP$-tagged, and ${K}_{S}^{0}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$-tagged events to determine these strong phase differences.

Abstract: We perform a Dalitz plot analysis of the decay D{sub s}{sup +}{yields}K{sup +}K{sup -}{pi}{sup +} with the CLEO-c data set of 586 pb{sup -1} of e{sup +}e{sup -} collisions accumulated at {radical}(s)=4.17 GeV. This corresponds to about 0.57x10{sup 6} D{sub s}{sup {+-}}D{sub s}*{sup {+-}} pairs from which we select 14 400 candidates with a background of roughly 15%. In contrast to previous measurements we find good agreement with our data only by including an additional f{sub 0}(1370){pi}{sup +} contribution. We measure the magnitude, phase, and fit fraction of K*(892){sup 0}K{sup +}, {phi}(1020){pi}{sup +}, K{sub 0}{sup *}(1430)K{sup +}, f{sub 0}(980){pi}{sup +}, f{sub 0}(1710){pi}{sup +}, and f{sub 0}(1370){pi}{sup +} contributions and limit the possible contributions of other KK and K{pi} resonances that could appear in this decay.

Abstract: Using a sample of $2.59\ifmmode\times\else\texttimes\fi{}{10}^{7}$ $\ensuremath{\psi}(2S)$ decays collected by the CLEO-c detector, we present results of a study of ${\ensuremath{\chi}}_{c0}$ and ${\ensuremath{\chi}}_{c2}$ decays into two-meson final states. We present the world's most precise measurements of the ${\ensuremath{\chi}}_{cJ,(J=0,2)}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$, ${\ensuremath{\pi}}^{0}{\ensuremath{\pi}}^{0}$, ${K}^{+}{K}^{\ensuremath{-}}$, ${K}_{S}^{0}{K}_{S}^{0}$, $\ensuremath{\eta}\ensuremath{\eta}$, and ${\ensuremath{\eta}}^{\ensuremath{'}}{\ensuremath{\eta}}^{\ensuremath{'}}$ branching fractions, and a search for ${\ensuremath{\chi}}_{c}$ decays into $\ensuremath{\eta}{\ensuremath{\eta}}^{\ensuremath{'}}$. These results shed light on the mechanism of charmonium decays into pseudoscalar mesons.

Abstract: Using {psi}(3770){yields}DD events collected with the CLEO-c detector at the Cornell e{sup +}e{sup -} storage ring, tagged by fully reconstructing one D meson in a hadronic decay mode, we measure absolute branching fractions and differential decay rates for D{sup 0}{yields}{pi}{sup -}e{sup +}{nu}{sub e}, D{sup +}{yields}{pi}{sup 0}e{sup +}{nu}{sub e}, D{sup 0}{yields}K{sup -}e{sup +}{nu}{sub e}, and D{sup +}{yields}K{sup 0}e{sup +}{nu}{sub e}. The measured decay rates are used to study semileptonic form factors governing these transitions and to test unquenched Lattice QCD (LQCD) calculations. We average our results with previously published CLEO-c measurements of the same quantities using a neutrino reconstruction technique. Combining LQCD calculations of form factor absolute normalizations f{sub +}(0) and measurements of f{sub +}{sup {pi}}(0)|V{sub cd}| and f{sub +}{sup K}(0)|V{sub cs}|, we find |V{sub cd}|=0.222(8)(3)(23) and |V{sub cs}|=1.018(10)(8)(106), where the uncertainties are statistical, experimental systematic, and from LQCD, respectively.

Abstract: We examine e{sup +}e{sup -}{yields}D{sub s}{sup -}D{sub s}*{sup +} and D{sub s}*{sup -}D{sub s}{sup +} interactions at 4170 MeV using the CLEO-c detector in order to measure the decay constant f{sub D{sub s}{sup +}} with good precision. Previously our measurements were substantially higher than the most precise lattice based QCD calculation of (241{+-}3) MeV. Here we use the D{sub s}{sup +}{yields}l{sup +}{nu} channel, where the l{sup +} designates either a {mu}{sup +} or a {tau}{sup +}, when the {tau}{sup +}{yields}{pi}{sup +}{nu}. Analyzing both modes independently, we determine B(D{sub s}{sup +}{yields}{mu}{sup +}{nu})=(0.565{+-}0.045{+-}0.017)%, and B(D{sub s}{sup +}{yields}{tau}{sup +}{nu})=(6.42{+-}0.81{+-}0.18)%. We also analyze them simultaneously to find an effective value of B{sup eff}(D{sub s}{sup +}{yields}{mu}{sup +}{nu})=(0.591{+-}0.037{+-}0.018)% and f{sub D{sub s}{sup +}}=(263.3{+-}8.2{+-}3.9) MeV. Combining with the CLEO-c value determined independently using D{sub s}{sup +}{yields}{tau}{sup +}{nu}, {tau}{sup +}{yields}e{sup +}{nu}{nu} decays, we extract f{sub D{sub s}{sup +}}=(259.5{+-}6.6{+-}3.1) MeV. Combining with our previous determination of B(D{sup +}{yields}{mu}{sup +}{nu}), we extract the ratio f{sub D{sub s}{sup +}}/f{sub D{sup +}}=1.26{+-}0.06{+-}0.02. No evidence is found for a CP asymmetry between {gamma}(D{sub s}{sup +}{yields}{mu}{sup +}{nu}) and {gamma}(D{sub s}{sup -}{yields}{mu}{sup -}{nu}); specifically the fractional difference in rates is measured to be (4.8{+-}6.1)%. Finally, we find B(D{sub s}{sup +}{yields}e{sup +}{nu})

We obtain B(D{sub s}{sup +}{yields}{tau}{sup +}{nu}{sub {tau}})=(5.30{+-}0.47{+-}0.22)% and determine the decay constant f{sub D{sub s}}=(252.5{+-}11.1{+-}5.2) MeV, where the first uncertainties are statistical and the second are systematic.

Abstract: Using 24.5 million psi(2S) decays collected with the CLEO-c detector at CESR we present the most precise measurements of magnetic dipole transitions in the charmonium system. We measure B(psi(2S)->gamma eta_c) = (4.32+/-0.16+/-0.60)x10^-3, B(J/psi->gamma eta_c)/B(psi(2S)->gamma eta_c) = 4.59+/-0.23+/-0.64, and B(J/psi->gamma eta_c) = (1.98+/-0.09+/-0.30)%. We observe a distortion in the eta_c line shape due to the photon-energy dependence of the magnetic dipole transition rate. We find that measurements of the eta_c mass are sensitive to the line shape, suggesting an explanation for the discrepancy between measurements of the eta_c mass in radiative transitions and other production mechanisms.

Abstract: Using {upsilon}(2S) and {upsilon}(3S) data collected with the CLEO III detector we have searched for decays of {chi}{sub bJ} to final states with open charm. We fully reconstruct D{sup 0} mesons with p{sub D{sup 0}}>2.5 GeV/c in three decay modes (K{sup -}{pi}{sup +}, K{sup -}{pi}{sup +}{pi}{sup 0}, and K{sup -}{pi}{sup -}{pi}{sup +}{pi}{sup +}) in coincidence with radiative transition photons that tag the production of one of the {chi}{sub bJ}(nP) states. Significant signals are obtained for the two J=1 states. Recent nonrelativistic QCD (NRQCD) calculations of {chi}{sub bJ}(nP){yields}ccX depend on one nonperturbative parameter per {chi}{sub bJ} triplet. The extrapolation from the observed D{sup 0}X rate over a limited momentum range to a full ccX rate also depends on these same parameters. Using our data to fit for these parameters, we extract results which agree well with NRQCD predictions, confirming the expectation that charm production is largest for the J=1 states. In particular, for J=1, our results are consistent with ccg accounting for about one-quarter of all hadronic decays.

We also determine upper limits for the electric dipole (E1) transitions {upsilon}(3S){yields}{gamma}{chi}{sub bJ}(1P)

The {chi}{sub c} states are produced in radiative decays of 3.08x10{sup 6} {psi}(2S) resonance decays and observed in the CLEO detector.

Abstract: In this Letter we describe a search for lepton flavor violation (LFV) in the bottomonium system. We search for leptonic decays of Upsilon(nS)(n=1,2, and 3) into muon and tau using the data collected with the CLEO III detector. We identify the tau lepton using its leptonic decay into electron and utilize multidimensional likelihood fitting with PDF shapes measured from independent data samples. We report our estimates of 95% CL upper limits on LFV branching fractions of Upsilon mesons. We interpret our results in terms of the exclusion plot for the energy scale of a hypothetical new interaction versus its effective LFV coupling in the framework of effective field theory., 10 pages, 3 figures, available through http://www.lns.cornell.edu/public/CLNS/, submitted to PRL

Abstract: A precision measurement of the mass of the h_c(1P1) state of charmonium has been made using a sample of 24.5 million psi(2S) events produced in e+e- annihilation at CESR. The reaction used was psi(2S) -> pi0 h_c, pi0 -> gamma gamma, h_c -> gamma eta_c, and the reaction products were detected in the CLEO-c detector. Data have been analyzed both for the inclusive reaction and for the exclusive reactions in which eta_c decays are reconstructed in fifteen hadronic decay channels. Consistent results are obtained in the two analyses. The averaged results of the present measurements are M(h_c)=3525.28+-0.19 (stat)+-0.12(syst) MeV, and B(psi(2S) -> pi0 h_c)xB(h_c -> gamma eta_c)= (4.19+-0.32+-0.45)x10^-4. Using the 3PJ centroid mass, Delta M_hf(1P)= - M(h_c) = +0.02+-0.19+-0.13 MeV.

Abstract: We search for a non-SM-like CP-odd Higgs boson (a{sub 1}{sup 0}) decaying to {tau}{sup +}{tau}{sup -} or {mu}{sup +}{mu}{sup -} in radiative decays of the {upsilon}(1S). No significant signal is found, and upper limits on the product branching ratios are set. Our {tau}{sup +}{tau}{sup -} results are almost 2 orders of magnitude more stringent than previous upper limits. Our data provide no evidence for a Higgs state with a mass of 214 MeV decaying to {mu}{sup +}{mu}{sup -}, previously proposed as an explanation for 3 {sigma}{sup +}{yields}p{mu}{sup +}{mu}{sup -} events observed by the HyperCP experiment.

Abstract: Using a total of 2.74 x 10^7 decays of the psi(2S) collected with the CLEO-c detector, we present a study of chi_cJ -> gamma V, where V = rho^0, omega, phi. The transitions chi_c1 -> gamma rho^0 and chi_c1 -> gamma omega are observed with B(chi_c1 -> gamma rho^0) = (2.43 +- 0.19 +- 0.22) x 10^-4 and B(chi_c1 -> gamma omega) = (8.3 +- 1.5 +- 1.2) x 10^-5. In the chi_c1 -> gamma rho^0 transition, the final state meson is dominantly longitudinally polarized. Upper limits on the branching fractions of other chi_cJ states to light vector mesons are presented., 10 pages, available through http://www.lns.cornell.edu/public/CLNS/

Abstract: A precision measurement of the mass of the h_{c}(1P1) state of charmonium has been made using a sample of 24.5x10;{6} psi(2S) events produced in e;{+}e;{-} annihilation at the Cornell Electron Storage Ring (CESR). The reaction used was psi(2S)-->pi;{0}h_{c}, pi;{0}-->gammagamma, h_{c}-->gammaeta_{c}, and the reaction products were detected in the CLEO-c detector. Data have been analyzed both for the inclusive reaction and for the exclusive reactions in which eta_{c} decays are reconstructed in 15 hadronic decay channels. Consistent results are obtained in the two analyses. The averaged results of the present measurements are M(h_{c})=3525.28+/-0.19(stat.)+/-0.12(syst.) MeV, and B(psi(2S)-->pi;{0}h_{c})xB(h_{c}-->gammaeta_{c})=(4.19+/-0.32+/-0.45)x10;{-4}. Using the ;{3}P_{J} centroid mass, DeltaM_{hf}(1P) identical withM(chi_{cJ})-M(h_{c})=+0.02+/-0.19+/-0.13 MeV.

Abstract: We measure the mass of the eta;{'} meson using psi(2S)-->pi;{+}pi;{-}J/psi, J/psi-->gammaeta;{'} events acquired with the CLEO-c detector operating at the CESR e;{+}e;{-} collider. Using three decay modes, eta;{'}-->rho;{0}gamma, eta;{'}-->pi;{+}pi;{-}eta with eta-->gammagamma, and eta;{'}-->pi;{+}pi;{-}eta with eta-->pi;{+}pi;{-}pi;{0}, we find M_{eta;{'}}=957.793+/-0.054+/-0.036 MeV, in which the uncertainties are statistical and systematic, respectively. This result is consistent with but substantially more precise than the current world average.

Abstract: We measure the branching ratio of the purely leptonic decay of the D{sup +} meson with unprecedented precision as B(D{sup +}{yields}{mu}{sup +}{nu})=(3.82{+-}0.32{+-}0.09)x10{sup -4}, using 818 pb{sup -1} of data taken on the {psi}(3770) resonance with the CLEO-c detector at the CESR collider. We use this determination to derive a value for the pseudoscalar decay constant f{sub D{sup +}}, combining with measurements of the D{sup +} lifetime and assuming |V{sub cd}|=|V{sub us}|. We find f{sub D{sup +}}=(205.8{+-}8.5{+-}2.5) MeV. The decay rate asymmetry ({gamma}(D{sup +}{yields}{mu}{sup +}{nu})-{gamma}(D{sup -}{yields}{mu}{sup -}{nu})/{gamma}(D{sup +}{yields}{mu}{sup +}{nu})+{gamma}(D{sup -}{yields}{mu}{sup -}{nu}))=0.08{+-}0.08, consistent with no CP violation. We also set 90% confidence level upper limits on B(D{sup +}{yields}{tau}{sup +}{nu})

Abstract: We perform a Dalitz plot analysis of D{sup +}{yields}K{sup -}{pi}{sup +}{pi}{sup +} decay with the CLEO-c data set of 572 pb{sup -1} of e{sup +}e{sup -} collisions accumulated at the {psi}(3770). This corresponds to 1.6x10{sup 6} D{sup +}D{sup -} pairs from which we select 140 793 candidate events with a small background of 1.1%. We compare our results with previous measurements using the isobar model. We modify the isobar model with an improved description of some of the contributing resonances and get better agreement with our data. We also consider a quasi-model-independent approach and measure the magnitude and phase of the contributing K{pi} S wave in the range of invariant masses from the threshold to the maximum in this decay. This gives an improved description of our data over the isobar model. Finally we allow for an isospin-two {pi}{sup +}{pi}{sup +} S wave contribution and find that adding this to both the isobar model and the quasi-model-independent approach gives the best description of our data.
