Abstract: We present measurements of decay matrix elements for hadronic transitions of the form Upsilon(nS)->Upsilon(mS)pi pi, where (n,m)=(3,1),(2,1),(3,2). We reconstruct charged and neutral pion modes with the final state Upsilon decaying to either mu(+)mu(-) 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 Upsilon(3S)->Upsilon(1S)pi pi 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 Upsilon(2S)->Upsilon(1S)pi pi and Upsilon(3S)->Upsilon(2S)pi pi transitions also show the presence of terms in the decay amplitude that were previously ignored, although at a relatively suppressed level.

Abstract: We present measurements of the inclusive branching fractions for the decays D+-> Xe+nu(e) and D-0 -> Xe+nu(e), using 281 pb(-1) of data collected on the psi(3770) resonance with the CLEO-c detector. We find B(D-0 -> Xe+nu(e))=(6.46 +/- 0.17 +/- 0.13)% and B(D+-> Xe+nu(e))=(16.13 +/- 0.20 +/- 0.33)%. Using the known D meson lifetimes, we obtain the ratio Gamma(+sl)(D)/Gamma(0sl)(D)=0.985 +/- 0.028 +/- 0.015, confirming isospin invariance at the level of 3%. The positron momentum spectra from D+ and D-0 have consistent shapes.

Abstract: From e(+)e(-) collision data acquired with the CLEO detector at the Cornell Electron Storage Ring, we observe the non-D (D) over bar decay psi(3770)->gamma chi(c1) with a statistical significance of 6.6 standard deviations, using the two-photon cascades to J/psi and J/psi ->center dot(+)center dot(-). We determine sigma(e(+)e(-)->psi(3770))xB(psi(3770)->gamma chi(c1))=(18.0 +/- 3.3 +/- 2.5) pb and branching fraction B(psi(3770)->gamma chi(c1))=(2.8 +/- 0.5 +/- 0.4)x10(-3). We set 90% C.L. upper limits for the transition to chi(c2) (chi(c0)): sigma xB < 5.7 pb (< 282 pb) and B < 0.9x10(-3) (< 44x10(-3)). We also determine Gamma(psi(3770)->gamma chi(c1))/Gamma(psi(3770)->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 281 pb(-1) of data collected with the CLEO-c detector, we report on first observations and measurements of Cabibbo-suppressed decays of D mesons in the following six decay modes: pi(+)pi(-)pi(0)pi(0), pi(+)pi(+)pi(-)pi(-)pi(0), pi(+)pi(0)pi(0), pi(+)pi(+)pi(-)pi(0), eta pi(0), and omega pi(+)pi(-). Improved branching fraction measurements in eight other multipion decay modes are also presented. The measured D ->pi pi rates allow us to extract the ratio of isospin amplitudes A(Delta I=3/2)/A(Delta I=1/2)=0.420 +/- 0.014(stat)+/- 0.016(syst) and the strong phase shift of delta(I)=(86.4 +/- 2.8 +/- 3.3)degrees, which is quite large and now more precisely determined.

Abstract: We describe a search for psi(3770) decay to two-body non-D (D) over bar final states in e(+)e(-) data produced by the CESR collider and analyzed with the CLEO-c detector. Vector-pseudoscalar production rho(0)pi(0), rho(+)pi(-), omega pi(0), phi pi(0), rho eta, omega eta, phi eta, rho eta', omega eta', phi eta', K-*0(K-0) over bar, and K*K-+(-) is studied along with that of b(1)pi (b(1)(0)pi(0) and b(1)(+)pi(-)) and pi(+)pi(-)pi(0). The largest amount of disagreement between the expected rate for e(+)e(-)->gamma*-> X and that for e(+)e(-)-> X at root s = 3.773 GeV is found for X = phi eta, at an excess cross section of (2.4 +/- 0.6) pb [Gamma(phi eta)(psi(3770))=(7.4 +/- 1.6) keV], and a suggestive suppression is seen for pi(+)pi(-)pi(0) and rho pi. We conclude with form factor determinations for omega pi(0), rho eta, and rho eta(').

Abstract: We present an improved measurement of the eta(') meson energy spectrum in Upsilon(1S) decays, using 1.2 fb(-1) of data taken at the Upsilon(1S) center-of-mass energy with the CLEO III detector. We compare our results with models of the eta(') gluonic form factor that have been suggested to explain the unexpectedly large B ->eta X-'(s) rate. Models based on perturbative QCD fail to fit the data for large eta(') energies, and thus an explanation outside the realm of the Standard Model or an improved understanding of nonperturbative QCD effects may be needed to account for this large rate.

Abstract: From e(+)e(-) collision data acquired with the CLEO-c detector at CESR, we search for the non-D (D) over bar decays psi(3770)->gamma chi(cJ), with chi(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(3)D(1) state of charmonium, but only if relativistic corrections are applied.

Abstract: We present model independent measurements of the helicity basis form factors in the decay D+-> K-pi(+)e(+)nu(e) obtained from about 2 800 decays reconstructed from a 281 pb(-1) data sample collected at the psi(3770) center-of-mass energy with the CLEO-c detector. We confirm the existence of a previously observed spin-zero K-pi(+) component interfering with the (K) over bar (*0) amplitude. We see no evidence for additional d- or f-wave contributions.

Abstract: Using the current world's largest data sample of psi(3770) decays, we present results of a search for the non-D (D) over bar decay psi(3770)->(KSKL0)-K-0. We find no signal, and obtain an upper limit of sigma(e(+)e(-)->psi(3770)->(KSKL0)-K-0)< 0.07 pb at 90% confidence level (CL). Our result tests a theoretical prediction for the upper bound on B(psi(3770)->(KSKL0)-K-0) based on a charmonia-mixing model.

Abstract: We test whether or not the tau lepton manifests the same couplings as the mu lepton by investigating the relative decay rates in purely leptonic D+ meson decays. We use 281 pb(-1) of data accumulated at the psi(3770) resonance with the CLEO-c detector, to limit B(D+->tau(+)nu)< 2.1x10(-3) at 90% confidence level (C.L.), thus allowing us to place the first upper limit on the ratio R=Gamma(D+->tau(+)nu)/Gamma(D+->mu(+)nu). The ratio of R to the standard model expectation of 2.65 then is < 1.8 at 90% C.L., consistent with the prediction of lepton universality.

We also determine the ratio Gamma(ee)[psi(2S)]/Gamma(ee)(J/psi)=0.45 +/- 0.01 +/- 0.02.

Abstract: Using the CLEO detector at the Cornell Electron Storage Ring, we have observed the B-s meson in e(+)e(-) annihilation at the Upsilon(5S) resonance. We find 14 candidates consistent with B-s decays into final states with a J/psi or a D-s(()*()-). The probability that we have observed a background fluctuation is less than 8x10(-10). We have established that at the energy of the Upsilon(5S) resonance B-s production proceeds predominantly through the creation of B-s*($) over bar (s)* pairs. We find sigma(e(+)e(-)-> B-s* (B) over bar (s)*)=[0.11(-0.03)(+0.04)(stat)+/- 0.02(syst)] nb, and set the following limits: sigma(e(+)e(-)-> B-s (B) over bar (s))/sigma(e(+)e(-)-> B-s*(B) over bar (s)*)< 0.16 and [sigma(e(+)e(-)-> B-s(B) over bar (s)*)+sigma(e(+)e(-)-> B-s*(B) over bar (s))]/sigma(e(+)e(-)-> B-s*(B) over bar (s)*)< 0.16 (90% C.L.). The mass of the B-s(*) meson is measured to be M-Bs*=[5.414 +/- 0.001(stat)+/- 0.003(syst)] GeV/c(2).

Abstract: We have searched for the di-pion transition chi(b)(2P) -> pi pi chi(b)(1P) in the CLEO III sample of Upsilon(3S) decays in the exclusive decay chain: Upsilon(3S) -> gamma chi(b)(2P), chi(b)(2P) -> pi pi chi(b)(1P), chi(b)(1P) -> gamma Upsilon(1S), Upsilon(1S) -> l(+)l(-). Our studies include both pi(+)pi(-) and pi(0)pi(0), each analyzed both in fully-reconstructed events and in events with one pion undetected. We show that the null hypothesis is not substantiated. Under reasonable assumptions, we find the partial decay width to be Gamma(chi(b)(2P) -> pi pi chi(b)(1P)) = (0.83 +/- 0.22 +/- 0.08 +/- 0.19) keV, with the uncertainties being statistical, internal CLEO systematics, and common systematics from outside sources.

Abstract: Using 420 pb(-1) of data collected on the Upsilon(5S) resonance with the CLEO III detector, we reconstruct B mesons in 25 exclusive decay channels to measure or set upper limits on the decay rate of Upsilon(5S) into B meson final states. We measure the inclusive B cross section to be sigma(Upsilon(5S)-> BB(X))=(0.177 +/- 0.030 +/- 0.016) nb and make the first measurements of the production rates of sigma(Upsilon(5S)-> (BB*)-B-*)=(0.131 +/- 0.025 +/- 0.014) nb and sigma(Upsilon(5S)-> BB*)=(0.043 +/- 0.016 +/- 0.006) nb, respectively. We set 90% confidence level limits of sigma(Upsilon(5S)-> BB)< 0.038 nb, sigma(Upsilon(5S)-> B((*))B((*))pi)< 0.055 nb and sigma(Upsilon(5S)-> BB pi pi)< 0.024 nb. We also extract the most precise value of the B-s(*) mass to date, M(B-s(*))=(5411.7 +/- 1.6 +/- 0.6) MeV/c(2).

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 Upsilon(1S)->gamma gg, Upsilon(2S)->gamma gg, Upsilon(3S)->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 pi(0) decays) are based on isospin symmetry rather than a determination of the pi(0) spectrum, which permits measurement of the Upsilon(2S) and Upsilon(3S) direct photon spectra without explicit corrections for pi(0) backgrounds from, e.g., 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 Upsilon(2S)->pi pi Upsilon(1S) to obtain a tagged sample of Upsilon(1S)->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 Upsilon -> ggg (R-gamma=B(gg gamma)/B(ggg)) to be R-gamma(1S)=(2.70 +/- 0.01 +/- 0.13 +/- 0.24)%, R-gamma(2S)=(3.18 +/- 0.04 +/- 0.22 +/- 0.41)%, and R-gamma(3S)=(2.72 +/- 0.06 +/- 0.32 +/- 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 alpha(s)(Q(2)) from R-gamma.

Abstract: Using 13.3 fb(-1) of e(+)e(-) collision data taken in the Upsilon(1S-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 pi(+)pi(-)J/psi, are confirmed. A good quality fit to our data is obtained with a single resonance. We determine M(Y(4260))=(4284(-16)(+17)(stat)+/- 4(syst)) MeV/c(2), Gamma(Y(4260))=(73(-25)(+39)(stat)+/- 5(syst)) MeV/c(2), and Gamma(ee)(Y(4260))xB(Y(4260)->pi(+)pi(-)J/psi)=(8.9(-3.1)(+3.9)(stat)+/- 1.8(syst)) eV/c(2).

Abstract: We determine the dielectron widths of the Upsilon(1S), Upsilon(2S), and Upsilon(3S) resonances with better than 2% precision by integrating the cross section of e(+)e(-)->Upsilon over the e(+)e(-) center-of-mass energy. Using e(+)e(-) energy scans of the Upsilon resonances at the Cornell Electron Storage Ring and measuring Upsilon production with the CLEO detector, we find dielectron widths of 1.252 +/- 0.004(sigma(stat))+/- 0.019(sigma(syst)) keV, 0.581 +/- 0.004 +/- 0.009 keV, and 0.413 +/- 0.004 +/- 0.006 keV for the Upsilon(1S), Upsilon(2S), and Upsilon(3S), respectively.

Abstract: We observe signals for the decays psi(3770)-> XJ/psi from data acquired with the CLEO detector operating at the CESR e(+)e(-) collider with root s=3773 MeV. We measure the following branching fractions B(psi(3770)-> XJ/psi) and significances: (189 +/- 20 +/- 20)x10(-5) (11.6 sigma) for X=pi(+)pi(-), (80 +/- 25 +/- 16)x10(-5) (3.4 sigma) for X=pi(0)pi(0), and (87 +/- 33 +/- 22)x10(-5) (3.5 sigma) for X=eta, where the errors are statistical and systematic, respectively. The radiative return process e(+)e(-)->gamma psi(2S) populates the same event sample and is used to measure Gamma(ee)[psi(2S)]=(2.54 +/- 0.03 +/- 0.11) keV.

Abstract: We have studied the Cabibbo-suppressed decay mode D-0 -> K+K-pi(0) using a Dalitz plot technique and find the strong phase difference delta(D)equivalent to delta K-*-(K)+-delta K-*+(K)-=332 degrees +/- 8 degrees +/- 11 degrees and relative amplitude r(D)equivalent to a(K)(*-)K(+)/a(K)(*+)K(-)=0.52 +/- 0.05 +/- 0.04. This measurement indicates significant destructive interference between D-0 -> K+(K-pi(0))(K)(*-) and D-0 -> K-(K+pi(0))(K)(*+) in the Dalitz plot region where these two modes overlap. This analysis uses 9.0 fb(-1) of data collected at root s approximate to 10.58 GeV with the CLEO III detector.

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 vertical bar V(ub)vertical bar from inclusive measurements of B -> X(u)l nu. Using a wide range of models based on available theoretical input we set a limit of Gamma(WA)/Gamma(b -> u)< 7.4% (90% confidence level) on the WA fraction, and assess the impact on previous inclusive determinations of vertical bar V(ub)vertical bar.

Abstract: The two-photon width of chi(c2)(P-3(2)) state of charmonium has been measured using 14.4 fb(-1) of e(+)e(-) data taken at root s=9.46-11.30 GeV with the CLEO III detector. The gamma gamma-fusion reaction studied is e(+)e(-)-> e(+)e(-)gamma gamma, gamma gamma ->chi(c2)->gamma J/psi ->gamma e(+)e(-)(mu(+)mu(-)). We measure Gamma(gamma gamma)(chi(c2))B(chi(c2)->gamma J/psi)B(J/psi -> e(+)e(-)+mu(+)mu(-))=13.2 +/- 1.4(stat)+/- 1.1(syst) eV, and obtain Gamma(gamma gamma)(chi(c2))=559 +/- 57(stat)+/- 48(syst)+/- 36(br) eV. This result is in excellent agreement with the result of gamma gamma-fusion measurement by Belle and is consistent with that of the (p) over barp ->chi(c2)->gamma gamma measurement, when they are both reevaluated using the recent CLEO result for the radiative decay chi(c2)->gamma J/psi.

223. Impact of a fictional reading intervention on empathy development in student pharmacists.

Author: Collins, Karin L., Zweber, Ann, and Irwin, Adriane N.
Abstract: Objective Determine the impact of a short longitudinal literary fiction intervention on empathy development in student pharmacists as measured by the Jefferson Scale of Empathy – Health Profession Students (JSE-HPS) version. Methods Twenty-one student pharmacists were randomized to an intervention consisting of reading short excerpts of literary fiction over eight weeks (n=11) or a control group not participating in the intervention (n=10). Both groups completed the JSE-HPS at baseline and completion of the literary intervention. Categorical data were compared using a chi-square or Fisher's exact test, and continuous data were compared using paired or independent t -tests for within and across group comparisons respectively. Results JSE-HPS scores increased in the intervention group (112.1±10.7 to 116.1±7.4; p=0.201) while they decreased in the control group (118.7±12.6 to 113.0±15.9; p=0.188). Changes across groups were not statistically significant (p=0.061). Conclusions Students randomized to an eight-week literature intervention demonstrated a non-statistically significant increase in empathy as measured by the JSE-HPS questionnaire. Similar increases were not observed in students randomized to a control group. As a result, this intervention may represent a novel way to foster empathy in student pharmacists using an intervention requiring few resources. Further research is needed with larger sample sizes, ideally across multiple institutions, in order to validate the effectiveness of this intervention. [ABSTRACT FROM AUTHOR]

Abstract: We use data collected by the CLEO III detector at the Cornell Electron Storage Ring to measure the inclusive yields of D-s mesons as B(Upsilon(5S)-> DsX)=(44.7 +/- 4.2 +/- 9.9)% and B(Upsilon(4S)-> DsX)=(18.1 +/- 0.5 +/- 2.8)%. From these measurements, we make a model dependent estimate of the ratio of B-s((*)) (B) over bar ((*))(s) to the total b (b) over bar quark pair production of (16.0 +/- 2.6 +/- 5.8)% at the Upsilon(5S) energy.

Abstract: The h(c)(P-1(1)) state of charmonium has been observed in the reaction psi(2S)->pi(0)h(c)->(gamma gamma)(gamma eta(c)) using 3.08x10(6) psi(2S) decays recorded in the CLEO detector. Data have been analyzed both for the inclusive reaction, where the decay products of the eta(c) are not identified, and for exclusive reactions, in which eta(c) decays are reconstructed in seven hadronic decay channels. We find M(h(c))=3524.4 +/- 0.6 +/- 0.4 MeV which corresponds to a hyperfine splitting Delta M-hf(1P)equivalent to < M(P-3(J))>-M(P-1(1))=+1.0 +/- 0.6 +/- 0.4 MeV, and B(psi(2S)->pi(0)h(c))xB(h(c)->gamma eta(c))=(4.0 +/- 0.8 +/- 0.7)x10(-4).

Abstract: Using 55.8 pb(-1) of e(+)e(-) collisions recorded at the psi(3770) resonance with the CLEO-c detector at CESR, we determine absolute hadronic branching fractions of charged and neutral D mesons using a double tag technique. Among measurements for three D-0 and six D+ modes, we obtain reference branching fractions B(D-0-> K(-)pi(+))=(3.91 +/- 0.08 +/- 0.09)% and B(D+-> K(-)pi(+)pi(+))=(9.5 +/- 0.2 +/- 0.3)%, where the uncertainties are statistical and systematic, respectively. Final state radiation is included in these branching fractions by allowing for additional, unobserved, photons in the final state. Using a determination of the integrated luminosity, we also extract the cross sections sigma(e(+)e(-)-> D-0(D) over bar (0))=(3.60 +/- 0.07(-0.05)(+0.07)) nb and sigma(e(+)e(-) -> D+D-)=(2.79 +/- 0.07(-0.04)(+0.10)) nb.

Abstract: The spin-singlet P-wave state of charmonium, h(c)(P-1(1)), has been observed in the decay psi(2S)->pi(0)h(c) followed by h(c)->gamma eta(c). Inclusive and exclusive analyses of the M(h(c)) spectrum have been performed. Two complementary inclusive analyses select either a range of energies for the photon emitted in h(c)->gamma eta(c) or a range of values of M(eta(c)). These analyses, consistent with one another within statistics, yield M(h(c))=[3524.9 +/- 0.7 (stat)+/- 0.4 (sys)] MeV/c(2) and a product of the branching ratios B-psi(psi(2S)->pi(0)h(c))xB(h)(h(c)->gamma eta(c))=[3.5 +/- 1.0 (stat)+/- 0.7 (sys)]x10(-4). When the eta(c) is reconstructed in seven exclusive decay modes, 17.5 +/- 4.5 h(c) events are seen with an average mass M(h(c))=[3523.6 +/- 0.9 (stat)+/- 0.5 (sys)] MeV/c(2), and BpsiBh=[5.3 +/- 1.5 (stat)+/- 1.0 (sys)]x10(-4). If combined, the inclusive and exclusive data samples yield an overall mass M(h(c))=[3524.4 +/- 0.6 (stat)+/- 0.4 (sys)] MeV/c(2) and product of branching ratios BpsiBh=[4.0 +/- 0.8 (stat)+/- 0.7 (sys)]x10(-4). The h(c) mass implies a P-wave hyperfine splitting Delta M-HF(1P)equivalent to < M(1(3)P)>-M(1(1)P(1))=[1.0 +/- 0.6 (stat)+/- 0.4 (sys)] MeV/c(2).

Abstract: Using the CLEO detector at the Cornell Electron Storage Ring, we have studied the distribution of kinematic variables in the decay Lambda(c)(+)->Lambda e(+)nu(e). By performing a four-dimensional maximum likelihood fit, we determine the form factor ratio, R=f(2)/f(1)=-0.31 +/- 0.05(stat)+/- 0.04(syst), the pole mass, M-pole=[2.21 +/- 0.08(stat)+/- 0.14(syst)] GeV/c(2), and the decay asymmetry parameter of the Lambda(c)(+), alpha(Lambda c)=-0.86 +/- 0.03(stat)+/- 0.02(syst), for < q(2)>=0.67 (GeV/c(2))(2). We compare the angular distributions of the Lambda(c)(+) and (Lambda) over bar (-)(c) and find no evidence for CP violation: A(Lambda c)=(alpha(Lambda c)+alpha((Lambda) over barc))/(alpha(Lambda c)-alpha((Lambda) over barc))=0.00 +/- 0.03(stat)+/- 0.01(syst)+/- 0.02, where the third error is from the uncertainty in the world average of the CP-violating parameter, A(Lambda), for Lambda -> p pi(-).

Abstract: We analyze 13.8 fb(-1) of the integrated e(+)e(-) luminosity collected at 10.6 GeV center-of-mass energy with the CLEO II and CLEO II.V detectors to study exclusive two-photon production of hadrons with masses below 1.7 GeV/c(2) decaying into the K(S)(0)K(+/-)pi(-/+) final state. We observe two statistically significant enhancements in the eta(1475) mass region. These enhancements have large transverse momentum which rules them out as being due to pseudoscalar resonances but is consistent with the production of axial-vector mesons. We use tagged two-photon events to study the properties of the observed enhancements and associate them with the production of f(1)(1285) and f(1)(1420). Our nonobservation of eta(1475) is inconsistent by more than 2 standard deviations with the first observation of this resonance in two-photon collisions by the L3 experiment. We present our estimates for 90% confidence level upper limits on the products of two-photon partial widths of light pseudoscalar hadrons and their branching fractions into K-S(0)(pi(+)pi(-))K(+/-)pi(-/+).

Abstract: The rare tau lepton decays to four explicitly identified hadrons have been studied with the CLEO detector at the Cornell Electron Storage Ring using (7.56 +/- 0.15) fb(-1) of data collected near root s=10.58 GeV. The first statistically significant measurements of B(tau(-)-> K(-)pi(+)pi(-)pi(0)nu(tau),excludingK(0))=(7.4 +/- 0.8 +/- 1.1)x10(-4) and B(tau(-)-> K(-)K(+)pi(-)pi(0)nu(tau))=(5.5 +/- 1.4 +/- 1.2)x10(-5) are presented, including the first observation of the decay tau(-)-> K(-)omega nu(tau) with branching fraction, (4.1 +/- 0.6 +/- 0.7)x10(-4). We publish the first upper limit for B(tau(-)-> K(-)K(+)K(-)pi(0)nu(tau))< 4.8(6.1)x10(-6) at 90% (95%) confidence level. We measure for the first time the invariant mass distributions, which together with the branching fraction measurements are important ingredients that can be used to extract the standard model parameters, the strange quark mass, and the Cabibbo-Kobayashi-Maskawa element V-us.

Abstract: Using data recorded by the CLEO III detector at the Cornell electron storage ring (CESR), we have made measurements of some properties of the Sigma(c)(*)(++) and Sigma(c)(*)(0) charmed baryons. In particular: Gamma(Sigma(c)(*)(++)) = 14.4-1.5+1.6 +/- 1.4 MeV, M(Sigma(c)(*)(++)) - M(Lambda(c)(+)) = 231.5 +/- 0.4 +/- 0.3 MeV, Gamma(Sigma(c)(*0)) = 16.6-1.7+1.9 +/- 1.4 MeV, M(Sigma(c)(*0)) - M(Lambda(c)(+)) = 231.4 +/- 0.5 +/- 0.3 MeV.

Abstract: Using the CLEO II.V detector observing e(+)e(-) collisions at around 10.6 GeV we search for neutral D mixing in semileptonic D-0 decays tagged in charged D* decays. Combining the results from the Ke nu and K*e nu channels we find that the rate for D mixing is less than 0.0078 at 90% C.L.

Abstract: The resonant substructure in D-0-> K(S)(0)pi(+)pi(-) decays is described by a combination of ten quasi two-body intermediate states which include both CP-even and CP-odd eigenstates and one doubly Cabibbo suppressed channel. We present a formalism that connects the variation in D-0 decay time over the Dalitz plot with the mixing parameters, x and y, that describe off-shell and on-shell D-0-(D) over bar (0) mixing. We analyze the CLEO II.V data sample and find the parameters x and y are consistent with zero. We limit (-4.5 < x < 9.3)% and (-6.4 < y < 3.6)% at the 95% confidence level.
