Abstract: Using a sample of (448.1±2.9)×106 ψ(3686) events collected with the BESIII detector, we perform the first partial wave analysis of ψ(3686)→K+K−η. In addition to the well established states, ϕ(1020), ϕ(1680), and K3*(1780), contributions from X(1750), ρ(2150), ρ3(2250), and K2*(1980) are also observed. The X(1750) state is determined to be a 1−− resonance. The simultaneous observation of the ϕ(1680) and X(1750) indicates that the X(1750), with previous observations in photoproduction, is distinct from the ϕ(1680). The masses, widths, branching fractions of ψ(3686)→K+K−η, and the intermediate resonances are also measured.

Abstract: Using a data sample of 448.1×106 ψ(3686) events collected at s=3.686 GeV with the BESIII detector at the Beijing Electron-Positron Collider II, we search for the rare decay J/ψ→ϕe+e− via ψ(3686)→π+π−J/ψ. No signal events are observed and the upper limit on the branching fraction is set to be B(J/ψ→ϕe+e−)<1.2×10−7 at the 90% confidence level, which is still about one order of magnitude higher than the Standard Model prediction.

Abstract: We study the e^{+}e^{-}→γωJ/ψ process using 11.6 fb^{-1} e^{+}e^{-} annihilation data taken at center-of-mass energies from sqrt[s]=4.008 GeV to 4.600 GeV with the BESIII detector at the BEPCII storage ring. The X(3872) resonance is observed for the first time in the ωJ/ψ system with a significance of more than 5σ. The relative decay ratio of X(3872)→ωJ/ψ and π^{+}π^{-}J/ψ is measured to be R=1.6_{-0.3}^{+0.4}±0.2, where the first uncertainty is statistical and the second systematic (the same hereafter). The sqrt[s]-dependent cross section of e^{+}e^{-}→γX(3872) is also measured and investigated, and it can be described by a single Breit-Wigner resonance, referred to as the Y(4200), with a mass of 4200.6_{-13.3}^{+7.9}±3.0 MeV/c^{2} and a width of 115_{-26}^{+38}±12 MeV. In addition, to describe the ωJ/ψ mass distribution above 3.9 GeV/c^{2}, we need at least one additional Breit-Wigner resonance, labeled as X(3915), in the fit. The mass and width of the X(3915) are determined. The resonant parameters of the X(3915) agree with those of the Y(3940) in B→KωJ/ψ and of the X(3915) in γγ→ωJ/ψ observed by the Belle and BABAR experiments within errors.

Abstract: The CLEO detector is undergoing major improvements in conjunction with a high luminosity upgrade of the CESR e+e− collider. A novel element is a state of the art particle identification system, based on a proximity focused Ring Imaging Cherenkov detector. This detector will provide an excellent hadron identification at all the momenta relevant to the study of the decays of B mesons produced at the ϒ(4S) resonance. Some features unique to our design will be discussed together with some results achieved on individual components.

Abstract: Using data recorded by the CLEO-II detector at CESR, we report new measurements of the branching fractions for the decays of the charmed baryon {Lambda}{sub c}{sup +} into pK{sup {minus}}{pi}{sup +}{pi}{sup 0}, p{bar K}{sup 0}, p{bar K}{sup 0}{pi}{sup +}{pi}{sup {minus}}, and p{bar K}{sup 0}{pi}{sup 0}, all measured relative to pK{sup {minus}}{pi}{sup +}. The relative branching fractions are 0.67{plus_minus}0.04{plus_minus}0.11,0.46{plus_minus}0.02{plus_minus}0.04,0.52 {plus_minus}0.04{plus_minus}0.05, and 0.66{plus_minus}0.05{plus_minus}0.07, respectively. {copyright} {ital 1998} {ital The American Physical Society}

Abstract: We report the observation of the Cabibbo-suppressed decays {Lambda}{sub {ital c}}{sup +}{r_arrow}{ital pK{sup {minus}}K{sup +}} and {Lambda}{sub {ital c}}{sup +}{r_arrow}{ital p}{phi} using data collected with the CLEO II detector at CESR. 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: By analyzing 2.93 fb(-1) data collected at the center-of-mass energy root s = 3.773 GeV with the BESIII detector, we measure the absolute branching fraction of the semileptonic decay D+ -> (K) over bar (0)e(+)nu(e) to be B(D (+) -> (K) over bar (0)e(+)nu(e)) = (8.59 +/- 0.14 +/- 0.21)% using (K) over bar (0) -> K-S(0) -> pi(0) pi(0), where the first uncertainty is statistical and the second systematic. Our result is consistent with previous measurements within uncertainties..

Abstract: Using data collected in the region of the [Upsilon](4[ital S]) resonance with the CLEO II detector operating at the Cornell Electron Storage Ring, we report on evidence for the production of [Sigma][sub [ital c]][sup ++] and [Sigma][sub [ital e]][sup 0] baryons in [ital B] decays, with [Sigma][sub [ital c]][r arrow][Lambda][sub [ital c]][sup +][pi]. This observation is based on 77[plus minus]19[Sigma][sub [ital c]][sup ++] and 76[plus minus]21[Sigma][sub [ital c]][sup 0] candidates from [ital B] decays. We find the product branching fractions [ital scrB]([ital [bar B]][r arrow][Sigma][sub [ital c]][ital X])[ital scrB]([Lambda][sub [ital c]][sup +][r arrow][ital pK][sup [minus]][pi][sup +]) for [Sigma][sub [ital c]]=[Sigma][sub [ital c]][sup ++], [Sigma][sub [ital c]][sup 0], and [Sigma][sub [ital c]][sup +] to be (2.1[plus minus]0.8[plus minus]0.7)[times]10[sup [minus]4], (2.3[plus minus]0.8[plus minus]0.7)[times]10[sup [minus]4], and less than 4.8[times]10[sup [minus]4] at 90% confidence level, respectively. A study of the [Sigma][sub [ital c]][sup ++] and [Sigma][sub [ital c]][sup 0] momentum spectra indicates that [ital B] decays to two-body final states with [Sigma][sub [ital c]] are suppressed.

Abstract: We report on a measurement of the forward-backward charge asymmetry in e+e- --> qqBAR at KEK TRISTAN, where. the asymmetry is near maximum. We sum over all flavors and measure the asymmetry by determining the charge of the quark jets. In addition we exploit flavor dependencies in the jet charge determination to enhance the contributions of certain flavors. This provides a check on the asymmetries of individual flavors. The measurement agrees with the standard model expectations.

Abstract: Using the CLEO-II detector at CESR, we have observed the Ds1(2536)+ in the decay modes D s1 + →D ∗0 K + and D ∗+ K S + , and measured its fragmentation and production ratios. Using the helicity angle distribution of the daugter D ∗0 , we obtain new evidence for the assignment of 1+ for the spin and parity of the Ds1+. We also set upper limits on the decays D s1 + →D s ∗+ λ, D 0 K + and D+Ks0.

Abstract: The tau lepton electron branching fraction has been measured with the CLEO II detector at the Cornell Electron Storage Ring as [ital B][sub [ital e]]=0.1749[plus minus]0.0014[plus minus]0.0022, with the first error statistical and the second systematic. The measurement involves counting electron-positron annihilation events in which both taus decay to electrons, and normalizing to the number of tau-pair decays expected from the measured luminosity. Detected photons in these events constitute a definitive observation of tau decay radiation.

Abstract: Using date from [ital e][sup +][ital e[minus]] annihilation into hadrons taken on the [Upsilon](1[ital S]) and continuum, we are able to compare event properties of three-gluon ([ital ggg]) and quark-antiquark ([ital q[bar q]]) decays. By tagging radiative decays of the [Upsilon](3[ital S]) to the [chi][sub [ital b]][sup [prime]] states, we can make comparisons of the [chi][sub [ital b]][sup [prime]] event shapes with continuum and [ital ggg] decays of the [Upsilon](1[ital S]). Contrary to the notion that two-gluon ([ital gg]) events are globally very similar to [ital q[bar q]] jets, we infer from a study of the [chi][sub [ital b]][sup [prime]] ([ital J]=0 or 2) states that [ital gg] event shapes more closely resemble [ital ggg] decays of the [Upsilon](1[ital S]), whereas [ital q[bar q]g] decays of the [chi][sub [ital b]][sup [prime]] ([ital J]=1) state more closely resemble [ital q[bar q]] continuum events in their decay characteristics.

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 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: 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.

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 report new measurements of the branching fractions {ital B}({ital B}{sup {minus}}{r arrow}{ital D}{sup 0}{ital l{minus}}{bar {nu}}), {ital B}({ital {bar B}}{sup 0}{r arrow}{ital D}{sup +}{ital l{minus}}{bar {nu}}), and {ital B}({ital B}{sup {minus}}{r arrow}{ital D}{sup *0}{ital l{minus}}{bar {nu}}). Combining these results with our previous measurement of {ital B}({ital {bar B}}{sup 0}{r arrow}{ital D}{sup *+}{ital l{minus}}{bar {nu}}), we find that the ratio of semileptonic widths for final states with a vector meson and pseudoscalar meson is (2.6{sub {minus}0.6{minus}0.8}{sup +1.1+1.0}) and the ratio of charged- to neutral-{ital B}-meson lifetimes is (0.89{plus minus}0.19{plus minus}0.13)({ital f}{sub 00}/{ital f}{sub +{minus}}) where ({ital f}{sub 00}/{ital f}{sub +{minus}}) is the ratio of neutral- to charged-{ital B}-meson production at the {Upsilon}(4{ital S}). From the {ital {bar B}}{r arrow}{ital Dl}{sup {minus}}{bar {nu}} branching fraction, we calculate {vert bar}{ital V}{sub {ital c}{ital b}}{vert bar}=0.040{plus minus}0.006 {plus minus}0.006, where the first error is statistical and the second is systematic and dominated by the uncertainty in the {ital B}-meson lifetime.

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.

Abstract: Analyzing {upsilon}(nS) decays acquired with the CLEO detector operating at the CESR e{sup +}e{sup -} collider, we measure for the first time the product branching fractions B[{upsilon}(nS){yields}{gamma}{chi}{sub bJ}((n-1)P)]B[{chi}{sub bJ}(n-1)P){yields}X{sub i}] for n=2 and 3, where X{sub i} denotes, for each i, one of the 14 exclusive light-hadron final states for which we observe significant signals in both {chi}{sub bJ}(1P) and {chi}{sub bJ}(2P) decays. We also determine upper limits for the electric dipole (E1) transitions {upsilon}(3S){yields}{gamma}{chi}{sub bJ}(1P)

Abstract: We report the first observation of Y(2S) → ηY(1S), with a branching fraction Β = (2.1 +0.7 -0.6 (stat) ± 0.3(syst)) X 10 -4 and a statistical significance 5.3σ. Data were acquired with the CLEO III detector at the CESR e + e - symmetric collider. This is the first process observed involving a b-quark spin flip. For related transitions, 90% confidence limits in units of 10 -4 are Β(Y(2S) → π 0 Y(1S)) < 1.8, Β(Y(3S) → ηY(1S)) < 1.8, B(Y(3S) →π 0 Y(1S)) < 0.7, and Β(Y(3S) → π 0 Y(2S)) < 5.1.

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: 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: Using a sample of 1.8 million $D\overline{D}$ mesons collected at the $\ensuremath{\psi}(3770)$ with the CLEO-c detector, we study the semileptonic decays ${D}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{e}^{+}{\ensuremath{\nu}}_{e}$, ${D}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}{e}^{+}{\ensuremath{\nu}}_{e}$, ${D}^{0}\ensuremath{\rightarrow}{K}^{\ensuremath{-}}{e}^{+}{\ensuremath{\nu}}_{e}$, and ${D}^{+}\ensuremath{\rightarrow}{\overline{K}}^{0}{e}^{+}{\ensuremath{\nu}}_{e}$. For the total branching fractions we find $\mathcal{B}({D}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{e}^{+}{\ensuremath{\nu}}_{e})=0.299(11)(9)%$, $\mathcal{B}({D}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}{e}^{+}{\ensuremath{\nu}}_{e})=0.373(22)(13)%$, $\mathcal{B}({D}^{0}\ensuremath{\rightarrow}{K}^{\ensuremath{-}}{e}^{+}{\ensuremath{\nu}}_{e})=3.56(3)(9)%$, and $\mathcal{B}({D}^{+}\ensuremath{\rightarrow}{\overline{K}}^{0}{e}^{+}{\ensuremath{\nu}}_{e})=8.53(13)(23)%$, where the first error is statistical and the second systematic. In addition, form factors are studied through fits to the partial branching fractions obtained in five ${q}^{2}$ ranges. By combining our results with recent unquenched lattice calculations, we obtain $|{V}_{cd}|=0.217(9)(4)(23)$ and $|{V}_{cs}|=1.015(10)(11)(106)$, where the final error is theoretical.

Abstract: We exploit the quantum coherence between pair-produced D0 and D[over]0 in psi(3770) decays to study charm mixing, which is characterized by the parameters x and y, and to make a first determination of the relative strong phase delta between D0-->K+pi- and D[over]0-->K+pi-. Using 281 pb(-1) of e+e- collision data collected with the CLEO-c detector at Ecm=3.77 GeV, as well as branching fraction input and time-integrated measurements of RM identical with (x2 + y2)/2 and RWS identical with Gamma(D0-->K+pi-)/Gamma(D[over]0-->K+pi-) from other experiments, we find cosdelta=1.03(-0.17)(+0.31)+/-0.06, where the uncertainties are statistical and systematic, respectively. By further including other mixing parameter measurements, we obtain an alternate measurement of cosdelta=1.10+/-0.35+/-0.07, as well as x sindelta=(4.4(-1.8)(+2.7)+/-2.9)x10(-3) and delta=(22(-12-11)(+11+9)) degrees .

Abstract: Using $281\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ of data collected with the CLEO-c detector, we present new measurements of Cabibbo-suppressed decays of ${D}^{0}$ and ${D}^{+}$ mesons to $\ensuremath{\eta}$ and ${\ensuremath{\eta}}^{\ensuremath{'}}$ final states. We make first observations of ${D}^{0}\ensuremath{\rightarrow}{\ensuremath{\eta}}^{\ensuremath{'}}{\ensuremath{\pi}}^{0}$, $\ensuremath{\eta}\ensuremath{\eta}$, $\ensuremath{\eta}{\ensuremath{\eta}}^{\ensuremath{'}}$, and $\ensuremath{\eta}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$, and find evidence for ${D}^{+}\ensuremath{\rightarrow}\ensuremath{\eta}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{0}$, ${D}^{+}\ensuremath{\rightarrow}{\ensuremath{\eta}}^{\ensuremath{'}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{0}$, and ${D}^{0}\ensuremath{\rightarrow}{\ensuremath{\eta}}^{\ensuremath{'}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$. We also report on improved measurements of ${D}^{0}\ensuremath{\rightarrow}\ensuremath{\eta}{\ensuremath{\pi}}^{0}$, ${D}^{+}\ensuremath{\rightarrow}\ensuremath{\eta}{\ensuremath{\pi}}^{+}$, and ${D}^{+}\ensuremath{\rightarrow}{\ensuremath{\eta}}^{\ensuremath{'}}{\ensuremath{\pi}}^{+}$. Using the measured two-body Cabibbo-suppressed decays, we extract amplitudes for specific flavor topologies and compare them to those from Cabibbo-favored decays.

Abstract: Using 281 pb{sup -1} of data collected with the CLEO-c detector at the {psi}(3770) resonance, we have studied Cabibbo-suppressed decays of D mesons to final states with two kaons. We present results for the absolute branching fractions of the modes D{sup 0}{yields}K{sup +}K{sup -}, D{sup 0}{yields}K{sub S}{sup 0}K{sub S}{sup 0}, and D{sup +}{yields}K{sup +}K{sub S}{sup 0}. We measure B(D{sup 0}{yields}K{sup +}K{sup -})=(4.08{+-}0.08{+-}0.09)x10{sup -3}, B(D{sup 0}{yields}K{sub S}{sup 0}K{sub S}{sup 0})=(1.46{+-}0.32{+-}0.09)x10{sup -4}, and B(D{sup +}{yields}K{sup +}K{sub S}{sup 0})=(3.14{+-}0.09{+-}0.08)x10{sup -3}. We also determine the ratio B(D{sup 0}{yields}K{sup +}K{sup -})/B(D{sup 0}{yields}{pi}{sup +}{pi}{sup -})=2.89{+-}0.05{+-}0.06. For each measurement, the first uncertainty is statistical and the second uncertainty is systematic.

Abstract: Using a sample of tagged D(s)(+) decays collected near the D(s)(*+/-)D(s)(-/+) peak production energy in e(+)e(-) collisions with the CLEO-c detector, we study the leptonic decay D(s)(+)-->tau(+)nu(tau) via the decay channel tau(+)-->e(+)nu(e)nu(tau). We measure B(D(s)(+)-->tau(+)nu(tau))=(6.17+/-0.71+/-0.34)%, where the first error is statistical and the second systematic. Combining this result with our measurements of D(s)(+)-->mu(+)nu(mu) and D(s)(+)-->tau(+)nu(tau) (via tau(+)-->pi(+)nu(tau)), we determine f(D(s))=(274+/-10+/-5) MeV.

Abstract: The branching fractions of D_s meson decays serve to normalize many measurements of processes involving charm quarks. Using 298 /pb of e+ e- collisions recorded at a center of mass energy of 4.17 GeV, we determine absolute branching fractions for eight D_s decays with a double tag technique. In particular we determine the branching fraction B(D_s -> K- K+ pi+) = (5.50 +- 0.23 +- 0.16)%, where the uncertainties are statistical and systematic respectively. We also provide partial branching fractions for kinematic subsets of the K- K+ pi+ decay mode., 6 pages, postscript also available through http://www.lns.cornell.edu/public/CLNS/2007/, revised

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 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: The spin-singlet P-wave state of charmonium, h{sub c}({sup 1}P{sub 1}), has been observed in the decay {psi}(2S){yields}{pi}{sup 0}h{sub c} followed by h{sub c}{yields}{gamma}{eta}{sub c}. Inclusive and exclusive analyses of the M(h{sub c}) spectrum have been performed. Two complementary inclusive analyses select either a range of energies for the photon emitted in h{sub c}{yields}{gamma}{eta}{sub c} or a range of values of M({eta}{sub c}). These analyses, consistent with one another within statistics, yield M(h{sub c})=[3524.9{+-}0.7 (stat){+-}0.4 (sys)] MeV/c{sup 2} and a product of the branching ratios B{sub {psi}}({psi}(2S){yields}{pi}{sup 0}h{sub c})xB{sub h}(h{sub c}{yields}{gamma}{eta}{sub c})=[3.5{+-}1.0 (stat){+-}0.7 (sys)]x10{sup -4}. When the {eta}{sub c} is reconstructed in seven exclusive decay modes, 17.5{+-}4.5 h{sub c} events are seen with an average mass M(h{sub c})=[3523.6{+-}0.9 (stat){+-}0.5 (sys)] MeV/c{sup 2}, and B{sub {psi}}B{sub h}=[5.3{+-}1.5 (stat){+-}1.0 (sys)]x10{sup -4}. If combined, the inclusive and exclusive data samples yield an overall mass M(h{sub c})=[3524.4{+-}0.6 (stat){+-}0.4 (sys)] MeV/c{sup 2} and product of branching ratios B{sub {psi}}B{sub h}=[4.0{+-}0.8 (stat){+-}0.7 (sys)]x10{sup -4}. The h{sub c} mass implies a P-wave hyperfine splitting {delta}M{sub HF}(1P){identical_to} -M(1{sup 1}P{sub 1})=[1.0{+-}0.6 (stat){+-}0.4 (sys)] MeV/c{sup 2}.
