Abstract: We present a measurement of the atmospheric neutrino oscillation parameters using three years of data from the IceCube Neutrino Observatory. The DeepCore infill array in the center of IceCube enables the detection and reconstruction of neutrinos produced by the interaction of cosmic rays in Earth's atmosphere at energies as low as ∼5 GeV. That energy threshold permits measurements of muon neutrino disappearance, over a range of baselines up to the diameter of the Earth, probing the same range of L/Eν as long-baseline experiments but with substantially higher-energy neutrinos. This analysis uses neutrinos from the full sky with reconstructed energies from 5.6 to 56 GeV. We measure Δm322=2.31-0.13+0.11×10-3 eV2 and sin2θ23=0.51-0.09+0.07, assuming normal neutrino mass ordering. These results are consistent with, and of similar precision to, those from accelerator- and reactor-based experiments., 0, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract: We present a measurement of the atmospheric $\nu_e$ spectrum at energies between 0.1 TeV and 100 TeV using data from the first year of the complete IceCube detector. Atmospheric $\nu_e$ originate mainly from the decays of kaons produced in cosmic-ray air showers. This analysis selects 1078 fully contained events in 332 days of livetime, then identifies those consistent with particle showers. A likelihood analysis with improved event selection extends our previous measurement of the conventional $\nu_e$ fluxes to higher energies. The data constrain the conventional $\nu_e$ flux to be $1.3^{+0.4}_{-0.3}$ times a baseline prediction from a Honda's calculation, including the knee of the cosmic-ray spectrum. A fit to the kaon contribution ($\xi$) to the neutrino flux finds a kaon component that is $\xi =1.3^{+0.5}_{-0.4}$ times the baseline value. The fitted/measured prompt neutrino flux from charmed hadron decays strongly depends on the assumed astrophysical flux and shape. If the astrophysical component follows a power law, the result for the prompt flux is $0.0^{+3.0}_{-0.0}$ times a calculated flux based on the work by Enberg, Reno and Sarcevic., Comment: PRD accepted version

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

Abstract: We have performed a search for muon neutrinos from dark matter annihilation in the center of the Sun with the 79-string configuration of the IceCube neutrino telescope. For the first time, the DeepCore sub-array is included in the analysis, lowering the energy threshold and extending the search to the austral summer. The 317 days of data collected between June 2010 and May 2011 are consistent with the expected background from atmospheric muons and neutrinos. Upper limits are therefore set on the dark matter annihilation rate, with conversions to limits on spin-dependent and spin-independent WIMP-proton cross-sections for WIMP masses in the range 20 - 5000 GeV. These are the most stringent spin-dependent WIMP-proton cross-sections limits to date above 35 GeV., 7 pages, 3 figues

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

Abstract: Using data samples taken at the ϒ(4S) resonance and nearby continuum e + e - annihilation with the CLEO-II detector at CESR, we have measured the inclusive branching fraction B(B→ηX)=(17.6±1.1±1.2)%, and the momentum distribution of the η mesons from B meson decay. The η yield cannot be explained as arising solely from the decay of intermediate charmed mesons.

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

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

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

These branching fractions are measured with samples of lepton-tagged and 3 vs 3 events. We find {ital B}({tau}{sup {minus}}{r_arrow}{ital h}{sup {minus}}{ital h}{sup +}{ital h}{sup {minus}}{nu}{sub {tau}})=0.0951{plus_minus}0.0007 m*0.0020 and {ital B}({tau}{sup {minus}}{r_arrow}{ital h}{sup {minus}}{ital h}{sup +}{ital h}{sup {minus}}{pi}{sup 0}{nu}{sub {tau}})=0.0423{plus_minus} .0006{plus_minus}0.0022.

Abstract: The angular distributions of the decay ${\ensuremath{\Lambda}}_{c}^{+}\ensuremath{\rightarrow}\ensuremath{\Lambda}{e}^{+}{\ensuremath{\nu}}_{e}$ have been studied using the CLEO II detector. By performing a three-dimensional maximum likelihood fit, the form factor ratio ${R\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}f}_{2}{/f}_{1}$ is determined to be $\ensuremath{-}0.25\ifmmode\pm\else\textpm\fi{}0.14\ifmmode\pm\else\textpm\fi{}0.08$. The decay asymmetry parameter of the ${\ensuremath{\Lambda}}_{c}$ averaged over ${q}^{2}$ is calculated to be ${\ensuremath{\alpha}}_{{\ensuremath{\Lambda}}_{c}}{\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}\ensuremath{-}0.82}_{\ensuremath{-}0.06\ensuremath{-}0.03}^{+0.09+0.06}$.

Abstract: We have observed five new decay modes of the charmed baryon {Lambda}{sup +}{sub {ital c}} using data collected with the CLEO II detector. Four decay modes, {Lambda}{sup +}{sub {ital c}}{r_arrow}{ital p{bar K}}{sup 0}{eta}, {Lambda}{eta}{pi}{sup +}, {Sigma}{sup +}{eta}, and {Sigma}{sup *+}{eta}, are first observations of final states with an {eta} meson, while the fifth mode, {Lambda}{sup +}{sub {ital c}}{r_arrow}{Lambda}{ital {bar K}}{sup 0}{ital K}{sup +}, requires the creation of an {ital s{bar s}} quark pair. We measure the branching fractions of these modes relative to {Lambda}{sup +}{sub {ital c}}{r_arrow}{ital pK}{sup -}{pi}{sup +} to be 0.25{plus_minus}0.04{plus_minus}0.04, 0.35{plus_minus}0.05{plus_minus}0.06, 0.11{plus_minus}0.03{plus_minus}0.02, 0.17{plus_minus}0.04{plus_minus}0.03, and 0.12{plus_minus}0.02{plus_minus}0.02, respectively.

Abstract: Using data collected by the CLEO II detector, we have observed two states decaying to {Lambda}{sup +}{sub {ital c}}{pi}{sup +}{pi}{sup {minus}}. Relative to the {Lambda}{sup +}{sub {ital c}}, their mass splittings are measured to be +307.5{plus_minus}0.4{plus_minus}1.0 and +342.2{plus_minus}0.2{plus_minus}0.5MeV/{ital c}{sup 2}, respectively; this represents the first measurement of the less massive state. These two states are consistent with being orbitally excited, isospin zero {Lambda}{sup +}{sub {ital c}} states.

Abstract: We consider the decay of [Upsilon](1[ital S]) particles produced at CESR into a photon which is observed by the CLEO detector plus particles which are not seen. These could be real particles which fall outside of our acceptance, or particles which are noninteracting. We report the results of our search fo the process [Upsilon](1[ital S])[r arrow][gamma]+ unseen'' for photon energies [gt]1 GeV, obtaining limits for the case where unseen'' is either a single particle or a particle-antiparticle pair. Our upper limits represent the highest sensitivity measurements for such decays to date.

Abstract: From this partial width we calculate [ital [bar B]][r arrow][ital D][sup *][ital l][bar [nu]] branching fractions that do not depend on [ital f][sub +[minus]]/[ital f][sub 00] or the individual [ital B] lifetimes, but only on the charged to neutral [ital B] lifetime ratio. The product of the CKM matrix element [vert bar][ital V][sub [ital c][ital b]][vert bar] times the normalization of the decay form factor at the point of no recoil of the [ital D][sup *] meson, [ital scrF]([ital y]=1), is determined from a linear fit to the combined differential decay rate of the exclusive [ital [bar B]][r arrow][ital D][sup *][ital l][bar [nu]] decays: [vert bar][ital V][sub [ital c][ital b]][vert bar][ital scrF](1)=0.0351[plus minus]0.0019 (stat) [plus minus]0.0018 (syst) [plus minus]0.0008 (lifetime). The value for [vert bar][ital V][sub [ital c][ital b]][vert bar] is extracted using theoretical calculations of the form factor normalization.

Abstract: The CLEO II detector is used to search for the production of ${\mathrm{\ensuremath{\chi}}}_{\mathit{c}2}$ states in two-photon interactions.

Using 1.49 ${\mathrm{fb}}^{\mathrm{\ensuremath{-}}1}$ of data taken with beam energies near 5.29 GeV, the two-photon width of the ${\mathrm{\ensuremath{\chi}}}_{\mathit{c}2}$ is determined to be \ensuremath{\Gamma}(${\mathrm{\ensuremath{\chi}}}_{\mathit{c}2}$\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma})=1.08\ifmmode\pm\else\textpm\fi{}0.30(stat)\ifmmode\pm\else\textpm\fi{}0.26(syst) keV, in agreement with predictions from perturbative QCD.

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: A measurement of the cross section for the combined two-photon production of charged pion and kaon pairs is performed using 1.2~$\rm fb^{-1}$ of data collected by the CLEO~II detector at the Cornell Electron Storage Ring. The cross section is measured at invariant masses of the two-photon system between 1.5 and 5.0 GeV/$c^2$, and at scattering angles more than $53^\circ$ away from the $\gamma\gamma$ collision axis in the $\gamma\gamma$ center-of-mass frame. The large background of leptonic events is suppressed by utilizing the CsI calorimeter in conjunction with the muon chamber system. The reported cross section is compared with leading order QCD models as well as previous experiments. In particular, although the functional dependence of the measured cross section disagrees with leading order QCD at small values of the two-photon invariant mass, the data show a transition to perturbative behavior at an invariant mass of approximately 2.5 GeV/$c^2$. hardcopies with figures can be obtained by writing to to: Pam Morehouse preprint secretary Newman Lab Cornell University Ithaca, NY 14853 or by sending mail to: preprints@lns62.lns.cornell.edu, Comment: 15 pages (in REVTEX format)

Abstract: Branching ratios for the dominant Cabibbo-suppressed decays of the $\tau$ lepton have been measured by CLEO~II in $e^+ e^-$ annihilation at CESR ($\sqrt{s} \sim 10.6$~GeV) using kaons with momenta below $0.7\ \rm GeV/c$. The inclusive branching ratio into one charged kaon is $(1.60 \pm 0.12 \pm 0.19)\%$. For the exclusive decays, $B(\tau \to K^-) = (0.66 \pm 0.07 \pm 0.09)\%$, $B(\tau \to K^- \pi^0) = (0.51 \pm 0.10 \pm 0.07)\%$, and, based on three events, $B(\tau \to K^- \pi^0 \pi^0) < 0.3\%$ at the 90\% confidence level. These represent significant improvements over previous results. $B(\tau\to K^- \pi^0)$ is measured for the first time with exclusive $\pi^0$ reconstruction., Comment: 11 pages uuencoded compressed postscript (process with uudecode then gunzip). hardcopies with figures can be obtained by sending mail to: preprints@lns62.lns.cornell.edu

Abstract: The branching fractions for the five-charged-particle decays of the [tau] lepton have been measured in [ital e][sup +][ital e][sup [minus]] annihilations using the CLEO II detector at the Cornell Electron Storage Ring. Assuming all charged particles to be pions, the results are [ital B](3[pi][sup [minus]]2[pi][sup +][ge]0 neutrals [nu][sub [tau]])=(0.097[plus minus]0.005[plus minus]0.011)%, [ital B](3[pi][sup [minus]]2[pi][sup +][nu][sub [tau]])=(0.077[plus minus]0.005 [plus minus]0.009)%, [ital B](3[pi][sup [minus]]2[pi][sup +][pi][sup 0][nu][sub [tau]])=(0.019[plus minus]0.004[plus minus]0.004)%, and [ital B](3[pi][sup [minus]]2[pi][sup +]2[pi][sup 0][nu][sub [tau]])[lt]0.011% at the 90% C.L. [ital B](3[pi][sup [minus]]2[pi][sup [minus]][pi][sup 0][nu][sub [tau]]) is measured for the first time by exclusive [pi][sup 0] reconstruction. The results are compared with the predictions from the partially conserved-axial-current and conserved-vector-current hypotheses assuming isospin invariance.

Abstract: We have measured the vector-pseudoscalar mass splitting M(D s * + )-M(D s + )=144.22±0.47±0.37 MeV significantly more precisely than the previous world average. We minimize the systematic errors by also measuring the vector-pseudoscalar mass difference M(D* 0 )-M(D 0 ) using the radiative decay D* 0 →D 0 γ, obtaining [M(D s * + )-M(D s + )]-[M(D* 0 )-M(D 0 )] =2.09±0.47±0.37 MeV. This is then combined with our previous high-precision measurement of M(D* 0 )-M(D 0 ), which used the decay D* 0 →D 0 π 0 . We also measure the mass difference M(D s + )-M(D + )=99.5±0.6±0.3 MeV, using the φπ + decay modes of the D s + and D + mesons.

Abstract: Using data from the CLEO II detector at the Cornell Electron Storage Ring, we measure [ital scrB]([tau][sup [minus]][r arrow][ital h][sup [minus]][pi][sup 0][nu][sub [tau]]) where [ital h][sup [minus]] refers to either [pi][sup [minus]] or [ital K][sup [minus]]. We use three different methods to measure this branching fraction. The combined result is [ital scrB]([tau][sup [minus]][r arrow][ital h][sup [minus]][pi][sup 0][nu][sub [tau]])=0.2587[plus minus]0.0012[plus minus]0.0042, in good agreement with standard model predictions.

Abstract: We present a measurement of [Gamma]([ital D][sub [ital s]][sup +][r arrow][mu][sup +][nu])/[Gamma]([ital D][sub [ital s]][sup +][r arrow][phi][pi][sup +])= 0.245[plus minus]0.052[plus minus]0.074. Using this ratio and [ital scrB]([ital D][sub [ital s]][sup +][r arrow][phi][pi][sup +])=(3.7[plus minus]0.9)% we extract [ital f][sub [ital D][ital s]]=344[plus minus]37[plus minus]52[plus minus]42 MeV, where the last error is due to the uncertainty in the [ital D][sub [ital s]][sup +][r arrow][phi][pi][sup +] absolute branching ratio. This result is larger than most theoretical predictions.

Abstract: Using the CLEO II data sample, with an integrated luminosity of 1.8 fb[sup [minus]1] at and near the [Upsilon](4[ital S]) resonance, we have observed a signal for [ital D][sup 0][r arrow][ital K][sup +][pi][sup [minus]], which could be due to either [ital D][sup 0][ital [bar D]][sup 0] mixing or doubly Cabibbo suppressed decay, or a combination of the two. We find [ital scrB]([ital D][sup 0][r arrow][ital K][sup +][pi][sup [minus]])/[ital scrB]([ital D][sup 0][r arrow][ital K][sup [minus]][pi][sup +])=0.0077[plus minus]0 .0025(stat) [plus minus]0.0025(syst).

Abstract: Using the CLEO II detector, we have measured the branching fractions for [Upsilon](3[ital S])[r arrow][pi][pi][Upsilon](1[ital S]), [Upsilon](3[ital S])[r arrow][pi][pi][Upsilon](2[ital S]), and the cascade [Upsilon](3[ital S])[r arrow][Upsilon](2[ital S])+[ital X], [Upsilon](2[ital S])[r arrow][pi][sup +][pi][sup [minus]][Upsilon](1[ital S]), analyzing the exclusive mode where the daughter [Upsilon] state decays to a [ital e][sup +][ital e[minus]] or [mu][sup +][mu][sup [minus]] pair, as well as the inclusive [pi][sup +][pi][sup [minus]] transitions where the final [Upsilon] state decays into hadrons. Properties of the [pi][pi] system are analyzed. Searches for the cascade decay [Upsilon](3[ital S])[r arrow][pi][sup +][pi][sup [minus]][ital h][sub [ital b]], [ital h][sub [ital b]][r arrow][gamma][eta][sub [ital b]] and [Upsilon](3[ital S])[r arrow][pi][sup 0][ital h][sub [ital b]] were also performed.

Abstract: We report on the first search for atmospheric and for diffuse astrophysical neutrino-induced showers (cascades) in the IceCube detector using 257 days of data collected in the year 2007-2008 with 22 strings active. A total of 14 events with energies above 16 TeV remained after event selections in the diffuse analysis, with an expected total background contribution of $8.3\pm 3.6$. At 90% confidence we set an upper limit of $E^2\Phi_{90%CL}, Comment: 14 pages, 16 figures

Abstract: Using the CLEO II detector and a sample of 955 000 [Upsilon](4S) decays we have confirmed charmless semileptonic decays of [ital B] mesons. In the momentum interval 2.3--2.6 GeV/[ital c] we observe an excess of 107[plus minus]15[plus minus]11 leptons, which we attribute to [ital b][r arrow][ital ul][nu]. This result yields a model-dependent range of values for [vert bar][ital V][sub [ital u][ital b]]/[ital V][sub [ital c][ital b]][vert bar] that is lower than has been obtained in previous studies. For the inclusive spectator model of Altarelli [ital et] [ital al]. we find [vert bar][ital V][sub [ital u][ital b]]/[ital V][sub [ital c][ital b]][vert bar]=0.076[plus minus]0.008. Models that describe [ital b][r arrow][ital ul][nu] with a limited set of exclusive final states give [vert bar][ital V][sub [ital u][ital b]]/[ital V][sub [ital c][ital b]][vert bar]=0.06[minus]0.10.

Abstract: We observe the [Sigma][sub [ital c]][sup +] baryon decaying to [Lambda][sub [ital c]][sup +][pi][sup 0] and measure the mass difference [ital M]([Sigma][sub [ital c]][sup +])[minus][ital M]([Lambda][sub [ital c]][sup +]) to be 168.5[plus minus]0.2 MeV/[ital c][sup 2]. We also measure the mass differences [ital M]([Sigma][sub [ital c]][sup ++])[minus][ital M]([Lambda][sub [ital c]][sup +]) and [ital M]([Sigma][sub [ital c]][sup 0])[minus][ital M]([Lambda][sub [ital c]][sup +]) with improved precision and determine the isospin mass splittings [ital M]([Sigma][sub [ital c]][sup ++])[minus][ital M]([Sigma][sub [ital c]][sup 0]) and [ital M]([Sigma][sub [ital c]][sup +])[minus][ital M]([Sigma][sub [ital c]][sup 0]) to be 1.1[plus minus]0.4[plus minus]0.1 MeV/[ital c][sup 2] and 1.4[plus minus]0.5[plus minus]0.3 MeV/[ital c][sup 2], respectively. Our results indicate that the light quark mass difference does not dominate the isospin mass splitting in [Sigma][sub [ital c]].

Abstract: We have measured branching ratios for three [Lambda][sub [ital c]] decay modes that have a [Sigma][sup +] in the final state. Two of the observed decay modes, [Lambda][sub [ital c]][r arrow][Sigma][sup +][pi][sup 0] and [Lambda][sub [ital c]][sup +][r arrow][Sigma][sup +][omega], have no external [ital W]-emission amplitudes. Their branching ratios relative to the [ital pK][sup [minus]][pi][sup +] mode are 0.20[plus minus]0.03[plus minus]0.03 and 0.54[plus minus]0.13[plus minus]0.06, respectively. We have also significantly improved the measurement of the branching ratio for the previously observed decay mode [Lambda][sub [ital c]][sup +][r arrow][Sigma][sup +][pi][sup +][pi][sup [minus]]. We find its branching ratio relative to [ital pK][sup [minus]][pi][sup +] to be 0.74[plus minus]0.07[plus minus]0.09.

Abstract: Using the CLEO II detector at CESR we have studied [ital D][sup 0] decays into final states with a [ital [bar K]] [sup 0] or [ital [bar K]] [sup *0], and have measured branching ratios for the decay modes [ital D][sup 0][r arrow]([ital [bar K]] [sup 0]/[ital [bar K]] [sup *0])[pi][sup 0],[eta],[eta][prime]. These results are compared with predictions of various charm decay models, and contributions of final-state interactions are discussed.

Abstract: We report the measurement of new modes of the charmed baryon ${\mathrm{\ensuremath{\Lambda}}}_{\mathit{c}}^{+}$ using data recorded by the CLEO II detector at the Cornell Electron Storage Ring.

Abstract: Using data from CLEO II at the Cornell Electron Storage Ring we provide a new measurement of the branching fraction for [ital D][sup 0][r arrow][pi][sup +][pi][sup [minus]], and we present the first measurements of [ital D][sup 0][r arrow][pi][sup 0][pi][sup 0] and of [ital D][sup +][r arrow][pi][sup +][pi][sup 0], which is due to an isospin changing [Delta][ital I]=3/2 transition. From these data we extract the ratio of isospin amplitudes [vert bar][ital A][sub 2]/[ital A][sub 0][vert bar], and the cosine of the relative phase [delta]=[delta][sub 2][minus][delta][sub 0] between these amplitudes, for [ital D][r arrow][pi][pi] decays. Unlike the situation in kaon decay where [ital A][sub 2] is strongly suppressed, we find [vert bar][ital A][sub 2]/[ital A][sub 0][vert bar]=0.72[plus minus]0.13[plus minus]0.11 and cos[delta]=0.14[plus minus]0.13[plus minus]0.09.

Abstract: The decay [tau][sup [minus]][r arrow][pi][sup [minus]][pi][sup +][pi][sup [minus]]2[pi][sup 0][nu][sub [tau]] has been observed in [ital e][sup +][ital e[minus]] annihilation using the CLEO II detector at the Cornell Electron Storage Ring. In a data sample collected at [radical][ital s] [similar to]10.6 GeV, 668[plus minus]38 decay candidates have been identified by exclusively reconstructing two [pi][sup 0]'s accompanying three charged particles, which are assumed to be pions. Normalizing to the number of [tau] pairs detected with one charged particle recoiling against three charged particles, this yields a branching ratio of [ital B][sub 3[pi]2[pi]][sup 0]=(0.48[plus minus]0.04[plus minus]0.04)%. A signal of 430[plus minus]33 events for the decay [tau][sup [minus]][r arrow][pi][sup [minus]][omega][pi][sup 0][nu][sub [tau]] has also been observed, corresponding to a branching ratio of [ital B][sub [pi][omega][pi]][sup 0]=(0.39[plus minus]0.04[plus minus]0.04)%.

Abstract: We have measured the [ital B][sup 0][ital [bar B]0] mixing probability, [chi][sub [ital d]], using a sample of 965 000 [ital B[bar B]] pairs from [Upsilon](4[ital S]) decays. Counting dilepton events, we find [chi][sub [ital d]]=0.157[plus minus]0.016[plus minus]0.018[sub [minus]0.021][sup +0.028]. Using tagged [ital B][sup 0] events, we find [chi][sub [ital d]]=0.149[plus minus]0.023[plus minus]0.019[plus minus]0.010. The first (second) error is statistical (systematic). The third error reflects a [plus minus]15% uncertainty in the assumption, made in both cases, that charged and neutral [ital B] pairs contribute equally to dilepton events. We also obtain a limit on the [ital CP] impurity in the [ital B][sub [ital d]][sup 0] system, [vert bar]Re([epsilon][sub [ital B]][sup 0])[vert bar][lt]0.045 at 90% C.L.

Abstract: We have observed the decays [ital B][sup 0][r arrow][ital K][sup *](892)[sup 0][gamma] and [ital B][sup [minus]][r arrow][ital K][sup *](892)[sup [minus]][gamma], which are evidence for the quark-level process [ital b][r arrow][ital s][gamma]. The average branching fraction is (4.5[plus minus]1.5[plus minus]0.9)[times]10[sup [minus]5]. This value is consistent with standard model predictions from electromagnetic penguin diagrams.

Abstract: A limit on the tau neutrino mass [ital M][sub [nu][tau]] is obtained from a study of tau decays in the reaction [ital e][sup +][ital e[minus]][r arrow][tau][sup +][tau][sup [minus]] at center-of-mass energies [similar to]10.6 GeV. The result is based on an end-point analysis of the invariant mass spectrum of the decay products in the decay modes [tau][sup [minus]][r arrow]3[ital h][sup [minus]]2[ital h][sup +][nu][sub [tau]] and [tau][sup [minus]][r arrow]2[ital h][sup [minus]][ital h+]2[pi][sup 0][nu][sub [tau]]. The data sample used in this analysis contains 1.77[times]10[sup 6] tau pairs, corresponding to an integrated luminosity of 1.92 fb[sup [minus]1], and is substantially larger than previous data samples used to place a limit on [ital M][sub [nu][tau]]. The limit obtained for both five-hadron modes together is 32.6 MeV at 95% C.L.

We find [ital B][sub [ital h]2[pi]][sup 0]/[ital B][sub [ital h][pi]][sup 0]=0.345[plus minus]0.006[plus minus]0.016, [ital B][sub [ital h]3[pi]][sup 0]/[ital B][sub [ital h][pi]][sup 0]=0.041 [plus minus]0.003[plus minus]0.005, and [ital B][sub [ital h]4[pi]][sup 0]/[ital B][sub [ital h][pi]][sup 0]=0.006[plus minus]0.002[plus minus]0.002.

Abstract: We present a measurement of the lepton decay asymmetry ${\mathit{A}}_{\mathrm{fb}}$ in the reaction B\ifmmode\bar\else\textasciimacron\fi{}\ensuremath{\rightarrow}${\mathit{D}}^{\mathrm{*}}$${\mathit{l}}^{\mathrm{\ensuremath{-}}}$\ensuremath{\nu}${\mathrm{\ifmmode\bar\else\textasciimacron\fi{}}}_{\mathit{l}}$ using data collected with the CLEO II detector at the Cornell Electron Storage Ring (CESR). The value of ${\mathit{A}}_{\mathrm{fb}}$ confirms that the chirality of the weak interaction is predominantly left-handed in b\ensuremath{\rightarrow}c transitions as expected in the standard model, if it is assumed that the lepton current is also left-handed. Using ${\mathit{A}}_{\mathrm{fb}}$ and the previously determined branching ratio, ${\mathit{q}}^{2}$ distribution, and ${\mathit{D}}^{\mathrm{*}}$ polarization, we obtain the first measurement of the form-factor ratios that are used to describe this semileptonic decay.
