Abstract: The decay {tau}{sup {minus}}{r_arrow}2{pi}{sup {minus}}{pi}{sup + }3{pi}{sup 0}{nu}{sub {tau}} has been studied with the CLEOII detector at the Cornell Electron Storage Ring. The branching fraction is measured to be (2.85{plus_minus}0.56{plus_minus}0.51){times}10{sup {minus}4} . The result is in good agreement with the isospin expectation but somewhat below the conserved-vector-current prediction. We have searched for resonance substructure in the decay. Within the statistical precision, the decay is saturated by the channels {tau}{sup {minus}}{r_arrow}{pi}{sup {minus}}2{pi}{sup 0 }{omega}{nu}{sub {tau}} , 2{pi}{sup {minus}}{pi}{sup +}{eta}{nu}{sub {tau}} , and {pi}{sup {minus}}2{pi}{sup 0}{eta}{nu}{sub {tau}} . This is the first observation of this {omega} decay mode and the branching fraction is measured to be (1.89{sup +0.74}{sub {minus}0.67}{plus_minus}0.40) {times}10{sup {minus}4} . {copyright} {ital 1997} {ital The American Physical Society}

Abstract: We use the CLEO detector at the Cornell e{sup +}e{sup {minus}} storage ring, CESR, to search for the two-photon production of the glueball candidate f{sub J}(2220) in its decay to K{sub s}K{sub s} . We present a restrictive upper limit on the product of the two-photon partial width and the K{sub s}K{sub s} branching fraction, ({Gamma}{sub {gamma}{gamma}}B{sub K{sub s}K{sub s}}){sub f{sub J(2220) }} . We use this limit to calculate a lower limit on the stickiness, which is a measure of the two-gluon coupling relative to the two-photon coupling. This limit on stickiness indicates that the f{sub J}(2220) has substantial glueball content. {copyright} {ital 1997} {ital The American Physical Society}

Abstract: Using data collected in the region of the Upsilon(4S) resonance with the CLEO II detector operating at the Cornell Electron Storage Ring CESR, we present the first observation of B mesons decaying into the charmed strange baryons Xi_c0 and Xi_c+. We find 79 +/- 27 Xi_c0 and 125 +/- 28 Xi_c+ candidates from B decays, leading to product branching fractions of BR(Bbar -> Xi_c0 X)BR(Xi_c0 -> Xi- pi+) = (0.144 +/- 0.048 +/- 0.021) x 10^-3 and BR(Bbar -> Xi_c+ X)BR(Xi_c+ -> Xi- pi+ pi+) = (0.453 +/- 0.096 +0.085-0.065) x 10^-3.

Abstract: We have searched for the rare decay of the eta meson $\eta \to e^{+}e^{-}$ using the CLEO II detector. The $\eta$'s were produced in $e^{+}e^{-}$ collisions with 10 GeV center-of-mass energy at the Cornell Electron Storage Ring (CESR). We find with 90% confidence the upper limit on the branching fraction $B(\eta \to e^{+}e^{-}) < 7.7\times 10^{-5}$. The application of conventional elementary particle theory to this decay predicts a branching fraction of about $10^{-9}$.

Abstract: A search for the decay of the tau lepton to seven charged pions and one or zero pizero mesons was performed using the BaBar detector at the PEP-II asymmetric-energy e+e- collider. The analysis uses 232.2 fb-1 of data at center-of-mass energies on or near the Y(4S) resonance. We observe 24 events with an expected background of 21.6+-1.3 events. Without evidence for a signal, we calculate an upper limit of BR(tau- --> 4pi- 3pi+ (pizero) nu_tau) 4pi- 3pi+ nu_tau and tau- --> 4pi- 3pi+ pizero nu_tau.

Abstract: Using data collected in the region of the {Upsilon}(4S) resonance with the CLEO-II detector, they report on the first observation of exclusive decays of the B meson to final states with a charmed baryon. They have measured the branching fractions {Beta}(B{sup -} {yields} {Lambda}{sub c}{sup +}{bar p}{pi}{sup -}) = (0.62{sub -0.20}{sup +0.23} {+-} 0.11 {+-} 0.10) x 10{sup -3} and {Beta}({bar B}{sup 0} {yields} {Lambda}{sub c}{sup +}{bar p}{pi}{sup +}{pi}{sup -}) = (1.33{sub -0.42}{sup +0.46} {+-} 0.31 {+-} 0.21) x 10{sup -3}. In addition, they report upper limits for final states of the form {bar B} {yields} {Lambda}{sub c}{sup +}{bar p}(n{pi}) and {Lambda}{sub c}{sup +}{bar p}(n{pi}){pi}{sup 0} where (n{pi}) denotes up to four charged pions.

Abstract: We report new measurements of the differential and total branching ratios for inclusive B decay to D{sup 0}, D{sup +}, and D{sup *+} and the first measurement of the same quantities for inclusive B decay to D{sup *0}. Here B is the mixture of B{sub d} and B{sub u} from {Upsilon}(4S) decay. Furthermore, since more than one charm particle (or antiparticle) of the same kind can be produced in B decay, here {open_quotes}inclusive B branching ratio{close_quotes} is used to mean the average number of charm particles and their antiparticles of a certain species produced in B decay. We obtain the following results (the first error is statistical, the second systematic of this analysis, the third propagated from other measurements): B(B{r_arrow}D{sup 0}X)=(0.636{plus_minus}0.014{plus_minus}0.019{plus_minus}0.0 8), B(B{r_arrow}D{sup +}X)=(0.235{plus_minus}0.009{plus_minus}0.009{plus_minus}0.024), B(B{r_arrow}D{sup *0}X) =(0.247{plus_minus}0.012{plus_minus}0.018{plus_minus}0.018), B(B{r_arrow}D{sup *+}X)=(0.239{plus_minus}0.011{plus_minus}0.014{plus_minus}0. 09). The following ratio of branching ratios is not affected by most of the systematic errors: B(B{r_arrow}D{sup *0}X)/ B(B{r_arrow}D{sup *+}X)=(1.03{plus_minus}0.07{plus_minus}0.09{plus_minus}0.08). We also report the first measurement of the momentum-dependent D{sup *0} polarization and a new measurement of the D{sup *+} polarization in inclusive B decay. Using these measurements and other CLEO results and making some additional assumptions, we calculate the average number of c and {bar c} quarks produced in Bmore » decay to be {l_angle}n{sub c}{r_angle}=1.10{plus_minus}0.05. {copyright} {ital 1997} {ital The American Physical Society}« less

Abstract: We have observed new channels for $\ensuremath{\tau}$ decays with an $\ensuremath{\eta}$ in the final state. We study 3-prong tau decays, using the $\ensuremath{\eta}\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}$ and $\ensuremath{\eta}\ensuremath{\rightarrow}3{\ensuremath{\pi}}^{0}$ decay modes and 1-prong decays with two ${\ensuremath{\pi}}^{0}$'s using the $\ensuremath{\eta}\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}$ channel. The measured branching fractions are $B({\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}\ensuremath{\eta}{\ensuremath{\nu}}_{\ensuremath{\tau}})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}({3.4}_{\ensuremath{-}0.5}^{+0.6}\ifmmode\pm\else\textpm\fi{}0.6)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$ and $B({\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}2{\ensuremath{\pi}}^{0}\ensuremath{\eta}{\ensuremath{\nu}}_{\ensuremath{\tau}})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}(1.4\ifmmode\pm\else\textpm\fi{}0.6\ifmmode\pm\else\textpm\fi{}0.3)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$. We observe clear evidence for ${f}_{1}\ensuremath{\rightarrow}\ensuremath{\eta}\ensuremath{\pi}\ensuremath{\pi}$ substructure and measure $B({\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{f}_{1}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\nu}}_{\ensuremath{\tau}})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}({5.8}_{\ensuremath{-}1.3}^{+1.4}\ifmmode\pm\else\textpm\fi{}1.8)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$. We have also searched for ${\ensuremath{\eta}}^{\ensuremath{'}}(958)$ production and obtain 90% C.L. upper limits $B({\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\eta}}^{\ensuremath{'}}{\ensuremath{\nu}}_{\ensuremath{\tau}})l7.4\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$ and $B({\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}{\ensuremath{\eta}}^{\ensuremath{'}}{\ensuremath{\nu}}_{\ensuremath{\tau}})l8.0\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$.

Abstract: We have searched for lepton flavor violating decays of the {tau} lepton using final states with an electron or a muon and one or two {pi}{sup 0} or {eta} mesons but no neutrinos. The data used in the search were collected with the CLEO II detector at the Cornell Electron Storage Ring (CESR) and correspond to an integrated luminosity of 4.68 fb{sup {minus}1} . No evidence for signals was found, resulting in much improved limits on the branching fractions for the one-meson modes and the first upper limits for the two-meson modes. {copyright} {ital 1997} {ital The American Physical Society}

Abstract: Using the CLEO-II data set we have searched for the Cabibbo-suppressed decays B{sup 0} {yields} D*{sup +}D*{sup -}. For the decay B{sup 0} {yields} D*{sup +}D*{sup -}, we observe one candidate signal event, with an expected background of 0.022 {+-} 0.011 events. This yield corresponds to a branching fraction of {Beta}(B{sup 0} {yields} D*{sup +}D*{sup -}) = (5.3{sub -3.7}{sup +7.1}(stat) {+-} 1.0(syst)) x 10{sup -4} and an upper limit of {Beta}(B{sup 0} {yields} D*{sup +}D{sup -}) < 2.2 x 10{sup -3} at the 90% CL. For B{sup 0} {yields} D*{sup {+-}}D{sup {-+}} and B{sup 0} {yields} D{sup +}D{sup -}, no significant excess of signal above the expected background level is seen, and we calculate the 90% CL upper limits on the branching fractions to be {Beta}(B{sup 0} {yields} D*{sup {+-}}D{sup {-+}}) < 1.8 x 10{sup -3} and B(B{sup 0} {yields} D{sup +}D{sup -}) < 1.2 x 10{sup -3}.

Abstract: We have measured the spectral shape Michel parameters ρ and η using leptonic decays of the τ, recorded by the CLEO II detector. Assuming e-μ universality in the vectorlike couplings, we find ρeμ = 0.735 ± 0.013 ± 0.008 and ηeμ = -0.015 ± 0.061 ± 0.062, where the first error is statistical and the second systematic. We also present measurements for the parameters for e and μ final states separately.

Abstract: We report a measurement of the magnitude of the {nu}{sub {tau}} helicity from {tau}-pair events taken with the CLEO detector at the CESR electron-positron storage ring. Events in which each {tau} undergoes the decay {tau}{r_arrow}h{nu}, with h a charged pion or kaon, are analyzed for energy correlations between the daughter hadrons, yielding {vert_bar}{xi}{sub h}{vert_bar} = 1.03{plus_minus}0.06{plus_minus}0.04, with the first error statistical and the second systematic. {copyright} {ital 1997} {ital The American Physical Society}

Abstract: Using data taken with the CLEO II detector at the Cornell Electron Storage Ring, we have determined the ratio of branching fractions: ${R}_{\ensuremath{\gamma}}\ensuremath{\equiv}\ensuremath{\Gamma}(\ensuremath{\Upsilon}(1S)\ensuremath{\rightarrow}\ensuremath{\gamma}\mathrm{gg})/\ensuremath{\Gamma}(\ensuremath{\Upsilon}(1S)\ensuremath{\rightarrow}\mathrm{ggg})=[2.75\ifmmode\pm\else\textpm\fi{}0.04(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.15(\mathrm{syst})]%$. From this ratio, we have determined the QCD scale parameter ${\ensuremath{\Lambda}}_{\overline{\mathrm{MS}}}$ (defined in the modified minimal subtraction scheme) to be ${\ensuremath{\Lambda}}_{\overline{\mathrm{MS}}}=233\ifmmode\pm\else\textpm\fi{}11\ifmmode\pm\else\textpm\fi{}59$ MeV, from which we determine a value for the strong coupling constant ${\ensuremath{\alpha}}_{s}{(M}_{\ensuremath{\Upsilon}(1S)})=0.163\ifmmode\pm\else\textpm\fi{}0.002\ifmmode\pm\else\textpm\fi{}0.014$, or ${\ensuremath{\alpha}}_{s}{(M}_{Z})=0.110\ifmmode\pm\else\textpm\fi{}0.001\ifmmode\pm\else\textpm\fi{}0.007$.

Abstract: Using data recorded by the CLEO-II detector at CESR, we report evidence of a pair of excited charmed baryons, one decaying into {Lambda}{sup +}{sub c}{pi}{sup +} and the other into {Lambda}{sup +}{sub c}{pi}{sup -}. The doubly charged state has a measured mass difference M({Lambda}{sup +}{sub c}{pi}{sup +}) -M({Lambda}{sup +}{sub c}) of 234.5{plus_minus}1.1{plus_minus}0.8 MeV/c{sup 2} and a width of 17.9{sup +3.8}{sub -3.2}{plus_minus}4.0MeV/c{sup 2}, and the neutral state has a measured mass difference M({Lambda}{sup +}{sub c}{pi}{sup -}) -M({Lambda}{sup +}{sub c}) of 232.6{plus_minus}1.0{plus_minus}0.8 MeV/c{sup 2} and a width of 13.0{sup +3.7}{sub -3.0}{plus_minus}4.0MeV/c{sup 2}. We interpret these data as evidence of the {Sigma}{sup *++}{sub c} and {Sigma}{sup *0}{sub c}, the spin (3)/(2){sup +} excitations of the {Sigma}{sub c} baryons. {copyright} {ital 1997} {ital The American Physical Society}

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: CLEO has studied $B$ decays to $\ensuremath{\pi}\ensuremath{\ell}\ensuremath{\nu}$, $\ensuremath{\rho}\ensuremath{\ell}\ensuremath{\nu}$, and $\ensuremath{\omega}\ensuremath{\ell}\ensuremath{\nu}$, where $\ensuremath{\ell}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}eor\ensuremath{\mu}$, by incorporating the missing momentum into full $B$ reconstruction. With the ${B}^{0}$ and ${B}^{+}$ modes combined according to isospin predictions for the relative partial widths, we obtain $B({B}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\ell}}^{+}\ensuremath{\nu})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}(1.8\ifmmode\pm\else\textpm\fi{}0.4\ifmmode\pm\else\textpm\fi{}0.3\ifmmode\pm\else\textpm\fi{}0.2)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$ and $B({B}^{0}\ensuremath{\rightarrow}{\ensuremath{\rho}}^{\ensuremath{-}}{\ensuremath{\ell}}^{+}\ensuremath{\nu})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}(2.5\ifmmode\pm\else\textpm\fi{}{0.4}_{\ensuremath{-}0.7}^{+0.5}\ifmmode\pm\else\textpm\fi{}0.5)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$, where the errors are statistical, systematic, and the estimated model dependence. We also estimate $|{V}_{\mathrm{ub}}|\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}(3.3\ifmmode\pm\else\textpm\fi{}{0.2}_{\ensuremath{-}0.4}^{+0.3}\ifmmode\pm\else\textpm\fi{}0.7)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}3}$.

Abstract: We use data collected by the CLEO II detector at the Cornell Electron Storage Ring (CESR) to search for B{sup +} {yields} h{sup +}h{sup -}h{sup +} (non-resonant) decays, where h{sup {+-}} can be either {pi}{sup {+-}}, K{sup {+-}} or p({bar p}). We see no evidence for signals and set upper limits on the branching fractions in the range (2.8 - 8.9) x 10{sup -5}. If observed, these decays may display CP violating asymmetries.

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 recorded by the CLEO-II detector at CESR, they report the first observation of an excited charmed baryon decaying into {Xi}{sub c}{sup 0}{pi}{sup +}. The state has mass difference M({Xi}{sub c}{sup 0}{pi}{sup +}) = M({Xi}{sub c}{sup 0}) of 174.3 {+-} 0.5 {+-} 1.0 MeV/c{sup 2}, and a width of < 3.1 MeV/c{sup 2} (90% confidence level limit). They identify the new state as the {Xi}*{sub c}{sup +}, the isospin partner of the recently discovered {Xi}*{sub c}{sup 0}.

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: We present a model-independent measurement of B(D s − → Φπ − ) B(D 0 → K − π + ) by partially reconstructing the decay B 0 → D ∗+ D s ∗− . Using data collected with the CLEO II detector at CESR, we determine B(D s − → Φπ − ) B(D 0 → K − π + ) = 0.92 ± 0.20 (stat.) ± 0.11(syst.) . Our measurement of B ( D 0 → K − π + ) then gives B ( D s − → Φπ − ) = (3.59 ± 0.77 ± 0.48)%.

Abstract: The decay {tau}{sup -} {yields} K{sup -} {eta}{nu}{sub {tau}} has been observed with the CLEO II detector. The {eta} meson is reconstructed using two decay channels, {eta} {yields} {gamma}{gamma} and {pi}{sup +}{pi}{sup -}{pi}{sup 0}. The measured branching fraction is B({tau}{sup -} {yields} K{sup -}{eta}{nu}{sub {tau}}) = (2.6 {+-} 0.5 {+-} 0.5) x 10{sup -4}, somewhat higher than the theoretical estimates. An improved upper limit for the second-class-current decay {tau}{sup -} {yields} {pi}{sup -}{eta}{nu}{sub {tau}} is set, B({tau}{sup -} {yields} {pi}{sup -}{eta}{nu}{sub {tau}}) < 1.4 x 10{sup -4} at 95% CL, consistent with the theoretical expectations.

Abstract: Using a sample of $2.6\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $\ensuremath{\Upsilon}(4\mathrm{S})\ensuremath{\rightarrow}B\overline{B}$ events collected with the CLEO II detector at the Cornell Electron Storage Ring, we have measured the form factors for ${\overline{B}}^{0}\ensuremath{\rightarrow}{D}^{*+}{\ensuremath{\ell}}^{\ensuremath{-}}\overline{\ensuremath{\nu}}$. We perform a three-parameter fit with the joint distribution of four kinematic variables to obtain the form-factor ratios ${R}_{1}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.18\ifmmode\pm\else\textpm\fi{}0.30\ifmmode\pm\else\textpm\fi{}0.12$ and ${R}_{2}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.71\ifmmode\pm\else\textpm\fi{}0.22\ifmmode\pm\else\textpm\fi{}0.07,$ and the form-factor slope ${\ensuremath{\rho}}_{{A}_{1}}^{2}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.91\ifmmode\pm\else\textpm\fi{}0.15\ifmmode\pm\else\textpm\fi{}0.06,$ which is closely related to the slope of the Isgur-Wise function. The form-factor ratios are consistent with predicted corrections to the heavy-quark symmetry limit ${R}_{1}{\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}R}_{2}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1$.

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.

Abstract: Using the CLEO II detector at the Cornell Electron Storage Ring, we have searched for flavor changing neutral currents and lepton family number violations in D^0 meson decays. The upper limits on the branching fractions for D^0→l^+l^- and D^0→X^0l^+l^- are in the range 10^(-5) to 10^(-4), where X^0 can be a π^0, K_s^0, η, ρ^0, ω, K^(*0), or φ meson, and the l^+l^- pair can be e^+e^-, μ^+μ^-, or e^±μ^∓. Although these limits are above the theoretical predictions, most are new or an order of magnitude lower than previous limits.

Abstract: Using the CLEO II detector operating at the e + e − Cornell Electron Storage Ring (CESR), we present evidence for new decay modes of the Ξ c + into Ξ 0 π + , Ξ 0 π + π 0 , and Ξ 0 π + π − π + . The branching ratios of these decay modes, relative to Ξ c + → Ξ − π + π + , have been measured to be 0.55±0.13±0.09, 2.34±0.57±0.37, and 1.74±0.42±0.27, respectively.

Abstract: We have used the CLEO II detector and 2.06fb^(-1) of ϒ(4S) data to measure the B-meson semileptonic branching fraction. The B→Xeν momentum spectrum was obtained over nearly the full momentum range by using charge and kinematic correlations in events with a high-momentum lepton tag and an additional electron. We find B(B→Xeν) = (10.49±0.17±0.43)%, with overall systematic uncertainties less than those of untagged single-lepton measurements. We use this result to calculate the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element V_(cb) and to set an upper limit on the fraction of ϒ(4S) decays to final states other than BB .

Abstract: We have studied the Cabibbo suppressed and color suppressed two-body decays B to ψϱ (ψω or ψa 1 ). Using a data sample of 5.12 million B decays collected with the CLEO II detector we find the 90% confidence level upper limits for branching fractions of B 0 → ψϱ 0 and B 0 → ψω to be 2.5 · 10 −4 and 2.7 · 10 −4 , respectively. We also update the branching fraction B − → ψπ − to be (5.6 ± 2.7) · 10 −5 .

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: 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.

Abstract: We present measurements of spectral moments extracted from the invariant mass distributions of the final states of hadronic τ decay products recorded in the CLEO detector. From a fit of theoretical predictions to the measurements of spectral moments and the total hadronic decay width of the τ, we determine the strong coupling constant and a set of non-perturbative QCD parameters. The strong coupling constant is measured to be α s ( m τ ) = 0.306 ± 0.024, which when extrapolated to the Z mass, yields α s ( M z ) = 0.114 ± 0.003.

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: Using the CLEO II detector at the Cornell Electron Storage Ring we have observed the decay modes {Xi}{sup +}{sub {ital c}}{r_arrow}{Xi}{sup 0}{ital e}{sup +}{nu}{sub {ital e}} and {Xi}{sup 0}{sub {ital c}}{r_arrow}{Xi}{sup {minus}}{ital e}{sup +}{nu}{sub {ital e}} by the detection of a {Xi}-positron pair of appropriate invariant mass. We find {ital B} ({Xi}{sup +}{sub {ital c}}{r_arrow}{Xi}{sup 0}{ital e}{sup +}{nu}{sub {ital e}}){sigma}({ital e}{sup +}{ital e}{sup {minus}}{r_arrow} {Xi}{sup +}{sub {ital cX}})=1.55{plus_minus}0.33{plus_minus}0.25 pb, {ital B} ({Xi}{sup 0}{sub {ital c}}{r_arrow}{Xi}{sup {minus}}{ital e}{sup +}{nu}{sub {ital e}}){sigma}({ital e}{sup +}{ital e}{sup {minus}}{r_arrow} {Xi}{sup 0}{sub {ital cX}})=0.63{plus_minus}0.12{plus_minus}0.10 pb, {ital B} ({Xi}{sup +}{sub {ital c}}{r_arrow}{Xi}{sup {minus}}{pi}{sup +}{pi}{sup +})/ {ital B} ({Xi}{sup +}{sub {ital c}}{r_arrow}{Xi}{sup 0}{ital e}{sup +}{nu}{sub {ital e}})= 0.44{plus_minus}0.11{sub {minus}0.06}{sup +0.11}, and {ital B} ({Xi}{sup 0}{sub {ital c}}{r_arrow}{Xi}{sup {minus}}{pi}{sup +})/{ital B} ({Xi}{sup 0}{sub {ital c}}{r_arrow}{Xi}{sup {minus}}{ital e}{sup +}{nu}{sub {ital e}})= 0.32{plus_minus}0.10{sub {minus}0.03}{sup +0.05}. Assuming the {Xi}{sup +}{sub {ital c}} and {Xi}{sup 0}{sub {ital c}} are equally produced in {ital e}{sup +}{ital e}{sup {minus}} annihilation events at 10 GeV, the lifetime ratio of {Xi}{sup +}{sub {ital c}}/{Xi}{sup 0}{sub {ital c}} is measured to be 2.46{plus_minus}0.70{sub {minus}0.23}{sup +0.33}.

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.
