Abstract: We report on a search for the radiative decay of {upsilon}(1S) to the pseudoscalar mesons {eta} and {eta}{sup '} in (21.2{+-}0.2)x10{sup 6} {upsilon}(1S) decays collected with the CLEO III detector at the Cornell Electron Storage Ring. The {eta} meson was reconstructed in the three modes {eta}{yields}{gamma}{gamma}, {eta}{yields}{pi}{sup +}{pi}{sup -}{pi}{sup 0}, or {eta}{yields}{pi}{sup 0}{pi}{sup 0}{pi}{sup 0}. The {eta}{sup '} meson was reconstructed in the mode {eta}{sup '}{yields}{pi}{sup +}{pi}{sup -}{eta} with {eta} decaying through any of the above three modes, and also {eta}{sup '}{yields}{gamma}{rho}{sup 0}, where {rho}{sup 0}{yields}{pi}{sup +}{pi}{sup -}. Five out of the seven submodes are found to have very low backgrounds. In four of them we find no signal candidates and in one [{upsilon}(1S){yields}{gamma}{eta}{sup '}, {eta}{sup '}{yields}{pi}{sup +}{pi}{sup -}{eta}, {eta}{yields}{pi}{sup +}{pi}{sup -}{pi}{sup 0}] there are two good signal candidates, which is insufficient evidence to claim a signal. The other two submodes ({eta}{yields}{gamma}{gamma} and {eta}{sup '}{yields}{gamma}{rho}) are background limited, and show no excess of events in their signal regions. We combine the results from different channels and obtain upper limits at the 90% C.L. which are B({upsilon}(1S){yields}{gamma}{eta})

Abstract: We examine ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}_{s}^{\ensuremath{-}}{D}_{s}^{*+}$ and ${D}_{s}^{*\ensuremath{-}}{D}_{s}^{+}$ interactions at 4170 MeV using the CLEO-c detector in order to measure the decay constant ${f}_{{D}_{s}^{+}}$. We use the ${D}_{s}^{+}\ensuremath{\rightarrow}{\ensuremath{\ell}}^{+}\ensuremath{\nu}$ channel, where the ${\ensuremath{\ell}}^{+}$ designates either a ${\ensuremath{\mu}}^{+}$ or a ${\ensuremath{\tau}}^{+}$, when the ${\ensuremath{\tau}}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}\overline{\ensuremath{\nu}}$. Analyzing both modes independently, we determine $\mathcal{B}({D}_{s}^{+}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}\ensuremath{\nu})=(0.594\ifmmode\pm\else\textpm\fi{}0.066\ifmmode\pm\else\textpm\fi{}0.031)%$, and $\mathcal{B}({D}_{s}^{+}\ensuremath{\rightarrow}{\ensuremath{\tau}}^{+}\ensuremath{\nu})=(8.0\ifmmode\pm\else\textpm\fi{}1.3\ifmmode\pm\else\textpm\fi{}0.4)%$. We also analyze them simultaneously to find an effective value of ${\mathcal{B}}^{\mathrm{eff}}({D}_{s}^{+}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}\ensuremath{\nu})=(0.638\ifmmode\pm\else\textpm\fi{}0.059\ifmmode\pm\else\textpm\fi{}0.033)%$ and extract ${f}_{{D}_{s}^{+}}=274\ifmmode\pm\else\textpm\fi{}13\ifmmode\pm\else\textpm\fi{}7\text{ }\text{ }\mathrm{MeV}$. Combining with our previous determination of $\mathcal{B}({D}^{+}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}\ensuremath{\nu})$, we also find the ratio ${f}_{{D}_{s}^{+}}/{f}_{{D}^{+}}=1.23\ifmmode\pm\else\textpm\fi{}0.11\ifmmode\pm\else\textpm\fi{}0.04$. We compare to current theoretical estimates. Finally, we find $\mathcal{B}({D}_{s}^{+}\ensuremath{\rightarrow}{e}^{+}\ensuremath{\nu})l1.3\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$ at 90% confidence level.

Abstract: We present measurements of decay matrix elements for hadronic transitions of the form Υ(nS)→Υ(mS)ππ, where (n,m)=(3,1),(2,1),(3,2). We reconstruct charged and neutral pion modes with the final state Upsilon decaying to either μ^+μ^- or e^+e^-. Dalitz plot distributions for the 12 decay modes are fit individually as well as jointly assuming isospin symmetry, thereby measuring the matrix elements of the decay amplitude. We observe and account for the anomaly previously noted in the dipion invariant mass distribution for the Υ(3S)→Υ(1S)ππ transition and obtain good descriptions of the dynamics of the decay using the most general decay amplitude allowed by partial conservation of the axial-vector current considerations. The fits further indicate that the Υ(2S)→Υ(1S)ππ and Υ(3S)→Υ(2S)ππ transitions also show the presence of terms in the decay amplitude that were previously ignored, although at a relatively suppressed level.

Abstract: We measure the mass of the {eta} meson using {psi}(2S){yields}{eta}J/{psi} events acquired with the CLEO-c detector operating at the CESR e{sup +}e{sup -} collider. Using the four decay modes {eta}{yields}{gamma}{gamma}, 3{pi}{sup 0}, {pi}{sup +}{pi}{sup -}{pi}{sup 0}, and {pi}{sup +}{pi}{sup -}{gamma}, we find M{sub {eta}}=547.785{+-}0.017{+-}0.057 MeV, in which the first uncertainty is statistical and the second systematic. This result has an uncertainty comparable to the two most precise previous measurements and is consistent with that of NA48, but is inconsistent at the level of 6.5{sigma} with the much smaller mass obtained by GEM.

Abstract: We measure the decay constant f{sub D{sub s}{sup +}} using 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}. Using both measurements we find f{sub D{sub s}{sup +}}=274{+-}13{+-}7 MeV. Combining with our previous determination of f{sub D{sup +}}, we compute the ratio f{sub D{sub s}{sup +}}/f{sub D{sup +}}=1.23{+-}0.11{+-}0.04. We compare with theoretical estimates.

Abstract: We have studied semileptonic B decay to the exclusive charmless states π, ρ/ω, η and η' using the full 15.5 fb -1 CLEO Υ(4S) sample, with measurements performed in subregions of phase space to minimize dependence on a priori knowledge of the form factors involved. We find total branching fractions B(B 0 → π - l + ν) = (1.37 ± 0.15 stat ± 0.11 sys ) × 10 -4 and B(B 0 → ρ - l + ν) = (2.93 ± 0.37 stat ± 0.37 sys ) X 10 -4 . We find evidence for B + → η'l + ν, with B(B + → η'l + ν) = (2.66 ± ±0.80 stat ± 0.56 sys ) × 10 -4 and 1.20 × 10 -4 < B(B + → η'l + ν) < 4.46 × 10 -4 (90% CL). We also limit B(B + → ηl + ν) < 1.01 × 10 -4 (90% CL). By combining our B → πlν information with unquenched lattice calculations, we find |V ub | = (3.6 ± 0.4 stat ± 0.2 sys +0.6 0.4thy ) × 10 -3 .

Abstract: Using e + e - → hadrons data collected with the CLEO-III detector at the Cornell Electron Storage Ring, we study the inclusive production of baryons/antibaryons (p, A) and mesons (Φ and f 2 (1270)) in gluon-fragmentation and quark-fragmentation processes. We first corroborate previous per-event total particle yields in Υ(1S) → ggg compared with nearby continuum (e + e - → qq) indicating greater (∼ X2) per-event yields of baryons in 3-gluon fragmentation. We find similar results when we extend that comparison to include the Y(2S) and Y(3S) resonances. With higher statistics, we now also probe the momentum dependence of these per-event particle yields. Next, we compare particle production in the photon-tagged process Υ(1S) → ggγ with that in e + e - → qqy events, to allow comparison of two-parton with three-parton particle-specific fragmentation. For each particle, we determine the "enhancement" ratio, defined as the ratio of particle yields per gluon-fragmentation event compared to quark-fragmentation event. Thus defined, an enhancement of 1.0 implies equal per-event production in gluon and quark fragmentation. In the photon-tagged analysis (Y(1S) → ggγ compared to e + e - → qqy), we find almost no enhancement for protons ( ∼ 1.2 ± 0.1), but a significant enhancement ( ∼ 1.9 ± 0.3) for A's. This small measured proton enhancement rate is supported by a study of baryon production in Χ b2 → gg → p + X relative to Χ b1 → qqg → p + X. Overall, per-event baryon production in radiative two-gluon fragmentation is somewhat smaller than that observed in three-gluon decays of the Υ(1S). Our results for baryon production are inconsistent with the predictions of the JETSET (7.3) fragmentation model.

Abstract: We measure the mass of the eta meson using psi(2S) --etaJ/psi events acquired with the CLEO-c detector operating at the CESR e(+)e(-) collider. Using the four decay modes eta --gamma gamma, 3pi(0), pi(+)pi(-)pi(0), and pi(+)pi(-)gamma, we find M(eta) = 547.785 +/- 0.017 +/- 0.057 MeV, in which the first uncertainty is statistical and the second systematic. This result has an uncertainty comparable to the two most precise previous measurements and is consistent with that of NA48, but is inconsistent at the level of 6.5 sigma with the much smaller mass obtained by GEM.

Abstract: The decay psi(2S) --> eta J/psi is used to measure, for the first time, all prominent eta-meson branching fractions with the same experiment in the same dataset, thereby providing a consistent treatment of systematics across branching fractions. We present results for eta decays to gamma gamma, pi+pi-pi0, 3 pi0, pi+ pi- gamma, and e+ e- gamma, accounting for 99.9% of all eta decays. The precisions for several of the branching fractions and their ratios are improved. Two channels, pi+ pi- gamma and e+ e- gamma, show results that differ at the level of three standard deviations from those previously determined., 11 pages postscript,also available through http://www.lns.cornell.edu/public/CLNS/2007/, Submitted to PRL

Abstract: We perform a Dalitz plot analysis of ${D}^{+}\ensuremath{\rightarrow}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{+}$ decay with the CLEO-c data set of $572\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ of ${e}^{+}{e}^{\ensuremath{-}}$ collisions accumulated at the $\ensuremath{\psi}(3770)$. This corresponds to $1.6\ifmmode\times\else\texttimes\fi{}{10}^{6}$ ${D}^{+}{D}^{\ensuremath{-}}$ 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 $K\ensuremath{\pi}$ $S$ 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 ${\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{+}$ $S$ 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.

Abstract: We report on a study of exclusive radiative decays of the {upsilon}(1S) resonance into the final states {gamma}{pi}{sup 0}{pi}{sup 0}, {gamma}{eta}{eta} and {gamma}{pi}{sup 0}{eta}, using 1.13 fb{sup -1} of e{sup +}e{sup -} annihilation data collected at {radical}(s)=9.46 GeV with the CLEO III detector operating at the Cornell Electron Storage Ring. In the channel {gamma}{pi}{sup 0}{pi}{sup 0}, we measure the branching ratio for the decay mode {upsilon}(1S){yields}{gamma}f{sub 2}(1270) to be (10.5{+-}1.6(stat){sub -1.8}{sup +1.9}(syst))x10{sup -5}. We place upper limits on the product branching ratios for the isoscalar resonances f{sub 0}(1500) and f{sub 0}(1710) for the {pi}{sup 0}{pi}{sup 0} and {eta}{eta} decay channels. We also set an upper limit on the {upsilon}(1S) radiative decay into {pi}{sup 0}{eta}.

Abstract: We study semileptonic B decay to the exclusive charmless states pi, rho/omega, eta, and eta;{'} using the 16 fb(-1) CLEO Upsilon(4S) data sample. We find B(B0--pi-l+nu)=(1.37+/-0.15stat+/-0.11sys)x10(-4) and B(B0--rho-l+nu)=(2.93+/-0.37stat+/-0.37sys)x10(-4) and find evidence for B+--eta'l+nu, with B(B+--eta'l+nu)=(2.66+/-0.80stat+/-0.56sys)x10(-4). From our B--pilnu rate for q216 GeV2 and lattice QCD, we find |Vub|=(3.6+/0.4stat+/0.2syst-0.4thy+0.6)x10(-3) [corrected]

Abstract: Using a sample of $3\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $\ensuremath{\psi}(2S)$ decays recorded by the CLEO detector, we study three-body decays of the ${\ensuremath{\chi}}_{c0}$, ${\ensuremath{\chi}}_{c1}$, and ${\ensuremath{\chi}}_{c2}$ produced in radiative decays of the $\ensuremath{\psi}(2S)$. We consider the final states ${\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}\ensuremath{\eta}$, ${K}^{+}{K}^{\ensuremath{-}}\ensuremath{\eta}$, $p\overline{p}\ensuremath{\eta}$, ${\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\eta}}^{\ensuremath{'}}$, ${K}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}$, $p\overline{p}{\ensuremath{\pi}}^{0}$, ${\ensuremath{\pi}}^{+}{K}^{\ensuremath{-}}{K}_{\mathrm{S}}^{0}$, and ${K}^{+}\overline{p}\ensuremath{\Lambda}$, measuring branching fractions or placing upper limits. For ${\ensuremath{\chi}}_{c1}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}\ensuremath{\eta}$, ${K}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}$, and ${\ensuremath{\pi}}^{+}{K}^{\ensuremath{-}}{K}_{\mathrm{S}}^{0}$ our observed samples are large enough to indicate the largest contributions to the substructure.

Abstract: Using CLEO data, we study the production of the antideuteron, d, in {upsilon}(nS) resonance decays and the nearby continuum. The branching ratios obtained are B{sup dir}({upsilon}(1S){yields}dX)=(3.36{+-}0.23{+-}0.25)x10{sup -5}, B({upsilon}(1S){yields}dX)=(2.86{+-}0.19{+-}0.21)x10{sup -5}, and B({upsilon}(2S){yields}dX)=(3.37{+-}0.50{+-}0.25)x10{sup -5}, where the 'dir' superscript indicates that decays produced via reannihilation of the bb pair to a {gamma}* are removed from both the signal and the normalizing number of {upsilon}(1S) decays in order to isolate direct decays of the {upsilon}(1S) to ggg, gg{gamma}. Upper limits at 90% C.L. are given for B({upsilon}(4S){yields}dX)

Abstract: Using 5.63 pb^-1 of data accumulated at the psi(2S) resonance with the CLEO III and CLEO-c detectors corresponding to 3.08 million psi(2S) decays, a search is performed for the decay psi(2S) -> eta_c pi^+pi^-pi^0 to test a theoretical prediction based upon the assumption that the c \bar c pair in the psi(2S) does not annihilate directly into three gluons but rather survives before annihilating. No signal is observed, and a combined upper limit from six eta_c decay modes is determined to be B(psi(2S) -> eta_c pi^+pi^-pi^0) < 1.0 x 10^-3 at 90% C.L. This upper limit is about an order of magnitude below the theoretical expectation.

Abstract: Knowledge of the B{sub s} decay fraction of the {upsilon}(5S) resonance, f{sub S}, is important for B{sub s} meson studies at the {upsilon}(5S) energy. Using a data sample collected by the CLEO III detector at CESR consisting of 0.423 fb{sup -1} on the {upsilon}(5S) resonance, 6.34 fb{sup -1} on the {upsilon}(4S) and 2.32 fb{sup -1} in the continuum below the {upsilon}(4S), we measure B({upsilon}(5S){yields}{phi}X)=(13.8{+-}0.7{sub -1.5}{sup +2.3})% and B({upsilon}(4S){yields}{phi}X)=(7.1{+-}0.1{+-}0.6)%; the ratio of the two rates is (1.9{+-}0.1{sub -0.2}{sup +0.3}). This is the first measurement of the {phi} meson yield from the {upsilon}(5S). Using these rates, and a model dependent estimate of B(B{sub s}{yields}{phi}X), we determine f{sub S}=(24.6{+-}2.9{sub -5.3}{sup +11.0})%. We also update our previous independent measurement of f{sub S} made using the inclusive D{sub s} yields to now be (16.8{+-}2.6{sub -3.4}{sup +6.7})%, due to a better estimate of the number of hadronic events. We also report the total {upsilon}(5S) hadronic cross section above continuum to be {sigma}(e{sup +}e{sup -}{yields}{upsilon}(5S))=(0.301{+-}0.002{+-}0.039) nb. This allows us to extract the fraction of B mesons as (58.9{+-}10.0{+-}9.2)%, equal to 1-f{sub S}. Averaging the three methods gives a model dependent result of f{sub S}=(21{sub -3}{sup +6})%.

Abstract: A precision measurement of the D^0 meson mass has been made using ~281 pb-1 of e+e- annihilation data taken with the CLEO-c detector at the psi(3770) resonance. The exclusive decay D^0 -> (Ks phi) has been used to obtain M(D^0)=1864.847+-0.150(stat)+-0.095(syst) MeV. This corresponds to M(D^0 D^*0)=3871.81+-0.36 MeV, and leads to a well-constrained determination of the binding energy of the proposed (D^0 D^*0) molecule X(3872), E_b=0.6+-0.6 MeV., 8 pages postscript,also available through http://www.lns.cornell.edu/public/CLNS/2006/, Submitted to PRL

Abstract: Using data collected with the CLEO III detector at the CESR e(+)e(-) collider, we report on a first observation of the decay Y(3S) -> tau(+) tau(-), and precisely measure the ratio of branching fractions of Y(nS), n = 1, 2, 3, to tau(+) tau(-) and mu(+) mu(-) final states, finding agreement with expectations from lepton universality. We derive absolute branching fractions for these decays, and also set a limit on the influence of a low mass CP-odd Higgs boson in the decay of the Y(1S).

Abstract: We measure the decay constant f(Ds)(+) using the D-s(+)-> l(+)nu channel, where the l(+) designates either a mu(+) or a tau(+), when the tau(+)->pi(+)(v) over bar. Using both measurements we find f(Ds)(+)= 274 +/- 13 +/- 7 MeV. Combining with our previous determination of f(D)(+), we compute the ratio f(Ds)(+)/f(D)(+)= 1.23 +/- 0.11 +/- 0.04. We compare with theoretical estimates.

Abstract: Using a 281 pb(-1) data sample collected at the psi(3770) with the CLEO-c detector, we present the first absolute branching fraction measurement of the decay D-0 -> K-pi(+)pi(-)e(+)nu(e) at a statistical significance of about 4.0 standard deviations. We find 10 candidates consistent with the decay D-0 -> K-pi(+)pi(-)e(+)nu(e). The probability that a background fluctuation accounts for this signal is less than 4.1x10(-5). We find B(D-0 -> K-pi(+)pi(-)e(+)nu(e))=[2.8(-1.1)(+1.4)(stat)+/- 0.3(syst)]x10(-4). By restricting the invariant mass of the hadronic system to be consistent with K-1(1270), we obtain the product of branching fractions B(D-0 -> K-1(-)(1270)e(+)nu(e))xB(K-1(-)(1270)-> K-pi(+)pi(-))=[2.5(-1.0)(+1.3)(stat)+/- 0.2(syst)]x10(-4). Using B(K-1(-)(1270)-> K-pi(+)pi(-))=(33 +/- 3)%, we obtain B(D-0 -> K-1(-)(1270)e(+)nu(e))=[7.6(-3.0)(+4.1)(stat)+/- 0.6(syst)+/- 0.7]x10(-4). The last error accounts for the uncertainties in the measured K-1(-)(1270)-> K-pi(+)pi(-) branching fractions.

Abstract: We measure the inclusive branching fractions of charm mesons into three mesons with large ss content, namely, the {eta}, {eta}{sup '} and {phi}. Data were accumulated with the CLEO-c detector. For D{sup 0} and D{sup +} rates, we use 281 pb{sup -1} taken on the {psi}(3770) resonance, and for D{sub s}{sup +} rates, we use 195 pb{sup -1} taken at 4170 MeV. We find that the production rates of these particles are larger in D{sub s}{sup +} decays than in D{sup 0} and D{sup +} decays. The {phi} rate, in particular, is 15 times greater. These branching fractions can be used to measure B{sub s} yields either at the {upsilon}(5S) resonance or at hadron colliders.

Abstract: We present measurements of the inclusive branching fractions for the decays ${D}^{+}\ensuremath{\rightarrow}X{e}^{+}{\ensuremath{\nu}}_{e}$ and ${D}^{0}\ensuremath{\rightarrow}X{e}^{+}{\ensuremath{\nu}}_{e}$, using $281\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ of data collected on the $\ensuremath{\psi}(3770)$ resonance with the CLEO-c detector. We find $\mathcal{B}({D}^{0}\ensuremath{\rightarrow}X{e}^{+}{\ensuremath{\nu}}_{e})=(6.46\ifmmode\pm\else\textpm\fi{}0.17\ifmmode\pm\else\textpm\fi{}0.13)%$ and $\mathcal{B}({D}^{+}\ensuremath{\rightarrow}X{e}^{+}{\ensuremath{\nu}}_{e})=(16.13\ifmmode\pm\else\textpm\fi{}0.20\ifmmode\pm\else\textpm\fi{}0.33)%$. Using the known $D$ meson lifetimes, we obtain the ratio ${\ensuremath{\Gamma}}_{{D}^{+}}^{\mathrm{sl}}/{\ensuremath{\Gamma}}_{{D}^{0}}^{\mathrm{sl}}=0.985\ifmmode\pm\else\textpm\fi{}0.028\ifmmode\pm\else\textpm\fi{}0.015$, confirming isospin invariance at the level of 3%. The positron momentum spectra from ${D}^{+}$ and ${D}^{0}$ have consistent shapes.

Abstract: Using $13.3\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of ${e}^{+}{e}^{\ensuremath{-}}$ collision data taken in the $\ensuremath{\Upsilon}(1S\ensuremath{-}4S)$ region with the CLEO III detector at the CESR collider, a search has been made for the new resonance $Y(4260)$ recently reported by the BABAR Collaboration. The production of $Y(4260)$ in initial state radiation (ISR), and its decay into ${\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}J/\ensuremath{\psi}$, are confirmed. A good quality fit to our data is obtained with a single resonance. We determine $M(Y(4260))=({4284}_{\ensuremath{-}16}^{+17}(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}4(\mathrm{syst}))\text{ }\text{ }\mathrm{MeV}/{c}^{2}$, $\ensuremath{\Gamma}(Y(4260))=({73}_{\ensuremath{-}25}^{+39}(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}5(\mathrm{syst}))\text{ }\text{ }\mathrm{MeV}/{c}^{2}$, and ${\ensuremath{\Gamma}}_{ee}(Y(4260))\ifmmode\times\else\texttimes\fi{}\mathcal{B}(Y(4260)\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}J/\ensuremath{\psi})=({8.9}_{\ensuremath{-}3.1}^{+3.9}(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}1.8(\mathrm{syst}))\text{ }\text{ }\mathrm{eV}/{c}^{2}$.

We confirm the existence of a previously observed spin-zero K{sup -}{pi}{sup +} component interfering with the K*{sup 0} amplitude. We see no evidence for additional d- or f-wave contributions.

Abstract: We have studied the Cabibbo-suppressed decay mode ${D}^{0}\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}$ using a Dalitz plot technique and find the strong phase difference ${\ensuremath{\delta}}_{D}\ensuremath{\equiv}{\ensuremath{\delta}}_{{K}^{*\ensuremath{-}}{K}^{+}}\ensuremath{-}{\ensuremath{\delta}}_{{K}^{*+}{K}^{\ensuremath{-}}}=332\ifmmode^\circ\else\textdegree\fi{}\ifmmode\pm\else\textpm\fi{}8\ifmmode^\circ\else\textdegree\fi{}\ifmmode\pm\else\textpm\fi{}11\ifmmode^\circ\else\textdegree\fi{}$ and relative amplitude ${r}_{D}\ensuremath{\equiv}{a}_{{K}^{*\ensuremath{-}}{K}^{+}}/{a}_{{K}^{*+}{K}^{\ensuremath{-}}}=0.52\ifmmode\pm\else\textpm\fi{}0.05\ifmmode\pm\else\textpm\fi{}0.04$. This measurement indicates significant destructive interference between ${D}^{0}\ensuremath{\rightarrow}{K}^{+}({K}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}{)}_{{K}^{*\ensuremath{-}}}$ and ${D}^{0}\ensuremath{\rightarrow}{K}^{\ensuremath{-}}({K}^{+}{\ensuremath{\pi}}^{0}{)}_{{K}^{*+}}$ in the Dalitz plot region where these two modes overlap. This analysis uses $9.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of data collected at $\sqrt{s}\ensuremath{\approx}10.58\text{ }\text{ }\mathrm{GeV}$ with the CLEO III detector.

Abstract: From e{sup +}e{sup -} collision data acquired with the CLEO-c detector at CESR, we search for the non-DD decays {psi}(3770){yields}{gamma}{chi}{sub cJ}, with {chi}{sub cJ} reconstructed in four exclusive decays modes containing charged pions and kaons. We report the first observation of such decays for J=0 with a branching ratio of (0.73{+-}0.07{+-}0.06)%. The rates for different J are consistent with the expectations assuming {psi}(3770) is predominantly a 1{sup 3}D{sub 1} state of charmonium, but only if relativistic corrections are applied.

Abstract: Using the current world's largest data sample of $\ensuremath{\psi}(3770)$ decays, we present results of a search for the non-$D\overline{D}$ decay $\ensuremath{\psi}(3770)\ensuremath{\rightarrow}{K}_{S}^{0}{K}_{L}^{0}$. We find no signal, and obtain an upper limit of $\ensuremath{\sigma}({e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\ensuremath{\psi}(3770)\ensuremath{\rightarrow}{K}_{S}^{0}{K}_{L}^{0})l0.07\text{ }\text{ }\mathrm{pb}$ at 90% confidence level (CL). Our result tests a theoretical prediction for the upper bound on $\mathcal{B}(\ensuremath{\psi}(3770)\ensuremath{\rightarrow}{K}_{S}^{0}{K}_{L}^{0})$ based on a charmonia-mixing model.

Abstract: Using a sample of 3.08 million psi(2S) decays collected at sqrt{s} = 3.686 GeV with the CLEO detector at the Cornell Electron Storage Ring, we have measured the branching fractions for psi(2S) decays to pseudoscalar pairs pi+pi-, K+K-, and KsKl. We obtain B(psi(2S) -> pi+pi-) K+K-) = (6.3 +- 0.6(stat) +- 0.3(syst)) x 10^{-5}, and B(psi(2S) -> KsKl) = (5.8 +- 0.8(stat) +- 0.4(syst)) x 10^{-5}. The branching fractions allow extraction of the relative phase Delta = (95 +- 15) degrees and strength ratio R = (2.5 +- 0.4) of the three-gluon and one-photon amplitudes for these modes.

Abstract: Using data taken with the CLEO III detector at the Cornell Electron Storage Ring, we have investigated the direct photon spectrum in the decays $\ensuremath{\Upsilon}(1\mathrm{S})\ensuremath{\rightarrow}\ensuremath{\gamma}gg$, $\ensuremath{\Upsilon}(2\mathrm{S})\ensuremath{\rightarrow}\ensuremath{\gamma}gg$, $\ensuremath{\Upsilon}(3\mathrm{S})\ensuremath{\rightarrow}\ensuremath{\gamma}gg$. The latter two of these are first measurements. Our analysis procedures differ from previous ones in the following ways: (a) background estimates (primarily from ${\ensuremath{\pi}}^{0}$ decays) are based on isospin symmetry rather than a determination of the ${\ensuremath{\pi}}^{0}$ spectrum, which permits measurement of the $\ensuremath{\Upsilon}(2\mathrm{S})$ and $\ensuremath{\Upsilon}(3\mathrm{S})$ direct photon spectra without explicit corrections for ${\ensuremath{\pi}}^{0}$ backgrounds from, e.g., ${\ensuremath{\chi}}_{bJ}$ states, (b) we estimate the branching fractions with a parametrized functional form (exponential) used for the background, and c) we use the high-statistics sample of $\ensuremath{\Upsilon}(2\mathrm{S})\ensuremath{\rightarrow}\ensuremath{\pi}\ensuremath{\pi}\ensuremath{\Upsilon}(1\mathrm{S})$ to obtain a tagged sample of $\ensuremath{\Upsilon}(1\mathrm{S})\ensuremath{\rightarrow}\ensuremath{\gamma}+X$ events, for which there are no QED backgrounds. We determine values for the ratio of the inclusive direct photon decay rate to that of the dominant three-gluon decay $\ensuremath{\Upsilon}\ensuremath{\rightarrow}ggg\text{ }\text{ }({R}_{\ensuremath{\gamma}}=B(gg\ensuremath{\gamma})/B(ggg))$ to be ${R}_{\ensuremath{\gamma}}(1\mathrm{S})=(2.70\ifmmode\pm\else\textpm\fi{}0.01\ifmmode\pm\else\textpm\fi{}0.13\ifmmode\pm\else\textpm\fi{}0.24)%$, ${R}_{\ensuremath{\gamma}}(2\mathrm{S})=(3.18\ifmmode\pm\else\textpm\fi{}0.04\ifmmode\pm\else\textpm\fi{}0.22\ifmmode\pm\else\textpm\fi{}0.41)%$, and ${R}_{\ensuremath{\gamma}}(3\mathrm{S})=(2.72\ifmmode\pm\else\textpm\fi{}0.06\ifmmode\pm\else\textpm\fi{}0.32\ifmmode\pm\else\textpm\fi{}0.37)%$, where the errors shown are statistical, systematic, and theoretical model dependent, respectively. Given a value of ${Q}^{2}$, one can estimate a value for the strong coupling constant ${\ensuremath{\alpha}}_{s}({Q}^{2})$ from ${R}_{\ensuremath{\gamma}}$.

Abstract: From e(+)e(-) collision data acquired with the CLEO detector at the Cornell Electron Storage Ring, we observe the non-DD(_) decay Psi(3770))-->gammachi(c1) with a statistical significance of 6.6 standard deviations, using the two-photon cascades to J/Psi and J/Psi-->l(+)l(-). We determine sigma(e(=)e(-)-->Psi(3770))xBeta(Psi(3770)-->gammachi(c1))=(18.0 +/- 3.3 +/- 2.5) pb and branching fraction Beta(Psi(3770)-->gammachi(c1)=(2.8 +/- 0.5+/-0.4) x 10(-3). We set 90% C.L. upper limits for the transition to chi(c2) (chi(c0)): sigma x Beta pi(+)pi(-)J/Psi)=1.5 +/- 0.3 +/- 0.3 (>1.0 at 90% C.L.), which bears upon the interpretation of X(3872).

Abstract: Using data collected with the CLEO detector operating at the CESR e+e- collider at sqrt[s]=3.97-4.26 GeV, we investigate 15 charmonium decay modes of the psi(4040), psi(4160), and Y(4260) resonances. We confirm, at 11 sigma significance, the BABAR Y(4260)-->pi+pi- J/psi discovery, make the first observation of Y(4260)--> pi(0)pi(0) J/psi (5.1 sigma), and find the first evidence for Y(4260)-->K+K- J/psi(3.7 sigma). We measure e+e- cross sections at sqrt[s]=4.26 GeV as sigma(pi+pi- J/psi)=58(+12)(-10)+/-4 pb, sigma(pi(0)pi(0) J/psi)=23(+12)(-8)+/-1 pb, and sigma(K+K- J/psi)=9(+9)(-5)+/-1 pb, in which the uncertainties are statistical and systematic, respectively. Upper limits are placed on other decay rates from all three resonances.

Abstract: We present the first experimental limits on high-q^2 contributions to charmless semileptonic B decays of the form expected from the weak annihilation (WA) decay mechanism. Such contributions could bias determinations of |V_(ub)| from inclusive measurements of B→X_ulν. Using a wide range of models based on available theoretical input we set a limit of Γ_(WA)/Γ_(b→u)
