Abstract: Using 3.1 fb$^{-1}$ of data accumulated at the $\Upsilon$(4S) by the CLEO-II detector, corresponding to 3.3 million $B\bar{B}$ pairs, we have searched for the color-suppressed $B$ hadronic decay processes: $\bar{B}^0 \to D^0 (D^{*0}) X^0$, where $X^0$ is a light neutral meson $\pi^0$, $\rho^0$, $\eta$, $\eta'$ or $\omega$. No obvious signal is observed. We set 90 % C.L. upper limits on these modes, varying from $1.2 \times 10^{-4}$ for $\bar{B}^0 \to D^0 \pi^0$ to $1.9 \times 10^{-3}$ for $\bar{B}^0 \to D^{*0} \eta'$.

Abstract: We have searched for the decay $\stackrel{\ensuremath{\rightarrow}}{B}{D}_{s1}^{+}(2536)X$ and measured an upper limit for the inclusive branching fraction of $\mathcal{B}(\stackrel{\ensuremath{\rightarrow}}{B}{D}_{s1}^{+}X)l0.96%$ at the 90% confidence level. This limit is small compared with the total expected $\stackrel{\ensuremath{\rightarrow}}{B}{D}^{(*)}{D}^{(*)}\mathrm{KX}$ rate. Assuming factorization, the ${D}_{s1}^{+}$ decay constant is constrained to be ${f}_{{D}_{s1}^{+}}$114 MeV at the 90% confidence level, at least 2.5 times smaller than that of ${D}_{s}^{+}$.

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: 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: Using the CLEO detector at the Cornell e{sup +}e{sup {minus}} storage ring CESR we study the two-photon production of {Lambda}{bar {Lambda}}, making the first observation of {gamma}{gamma}{r_arrow}{Lambda}{bar {Lambda}}. We present the cross section for {gamma}{gamma}{r_arrow}{Lambda}{bar {Lambda}} as a function of the {gamma}{gamma} center of mass energy and compare it to that predicted by the quark-diquark model. {copyright} {ital 1997} {ital The American Physical Society}

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: Color-suppressed decays of $B$ mesons to final states with $\psi(2S)$ mesons have been observed with the CLEO detector. The branching fractions for the decays $B^+ \to \psi(2S) K^+$, $B^+ \to \psi(2S) K^*(892)^+$, $B^0 \to \psi(2S) K^0$, and $B^0 \to \psi(2S) K^*(892)^0$ are measured to be (7.8 +- 0.7 +- 0.9) 10^{-4}$, (9.2 +- 1.9 +- 1.2) 10^{-4}$, (5.0 +- 1.1 +- 0.6) 10^{-4}$, and (7.6 +- 1.1 +- 1.0) 10^{-4}$, respectively, where the first uncertainty is statistical and the second is systematic. The first measurement of the longitudinal polarization fraction is extracted from the angular analysis of the $B \to \psi(2S) K^*(892)$ candidates: $\Gamma_L / \Gamma = 0.45 +- 0.11 +- 0.04 $. Our measurements of the decays $B^0 \to \psi(2S) K^0$ and $B^+ \to \psi(2S) K^*(892)^+$ are first observations.

Abstract: Based on an a high statistics e+e- -> ccbar data sample, we report on the inclusive rate for charmed baryons to decay into / particles using charm-event tagging. We select e+e- -> ccbar events which have a clear anti-charm tag and measure the / content in the hemisphere opposite the tag (charge conjugate modes are implicit). This allows us to determine the product branching fraction: B(/)=B(c->Theta_c)*B(Theta_c->/\X), where Theta_c represents a sum over all charmed baryons produced in e+e- fragmentation at sqrt(s)=10.5 GeV, given our specific tags. We obtain B(/)=(1.87+/-0.03+/-0.33)%

Abstract: We search for the decay of the ${B}^{0}$ meson into a pair of leptons in the suppressed channels ${B}^{0}\ensuremath{\rightarrow}{e}^{+}{e}^{\ensuremath{-}},$ ${B}^{0}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ and in the lepton number violating channel ${B}^{0}\ensuremath{\rightarrow}{e}^{\ifmmode\pm\else\textpm\fi{}}{\ensuremath{\mu}}^{\ensuremath{\mp}}$ in a sample of $9.7\ifmmode\times\else\texttimes\fi{}{10}^{6} B\overline{B}$ pairs recorded by CLEO detector. No signal is found, and the following upper limits on the branching fractions are established: $\mathcal{B}{(B}^{0}\ensuremath{\rightarrow}{e}^{+}{e}^{\ensuremath{-}})l8.3\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}7},$ $\mathcal{B}{(B}^{0}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}})l6.1\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}7},$ $\mathcal{B}{(B}^{0}\ensuremath{\rightarrow}{e}^{\ifmmode\pm\else\textpm\fi{}}{\ensuremath{\mu}}^{\ensuremath{\mp}})l15\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}7}$ at 90% confidence level. A new lower limit on the Pati-Salam leptoquark mass ${M}_{\mathrm{LQ}}g27 \mathrm{TeV}$ is established at 90% confidence level.

19. Resonance structure of τ-→K-π+π-ντ decays

Abstract: Using a sample of 4.7 fb{sup -1} integrated luminosity accumulated with the CLEO II detector at the Cornell Electron Storage Ring (CESR), we investigate the mass spectrum and resonant structure in {tau}{sup -}{yields}K{sup -}{pi}{sup +}{pi}{sup -}{nu}{sub {tau}} decays. We measure the relative fractions of K{sub 1}(1270) and K{sub 1}(1400) resonances in these decays, as well as the K{sub 1} masses and widths. Our fitted K{sub 1} resonances are somewhat broader than previous hadroproduction measurements, and in agreement with recent CERN LEP results from tau decay. The larger central value of our measured width supports models which attribute the small {tau}{sup -}{yields}K{sup -}{pi}{sup +}{pi}{sup -}{nu}{sub {tau}} branching fraction to larger K{sub 1} widths than are presently tabulated. We also determine the K{sub a}-K{sub b} mixing angle {theta}{sub K}. (c) 2000 The American Physical Society.

Abstract: We present a study of three B{sup 0} decay modes useful for time-dependent CP asymmetry measurements. From a sample of 9.7x10{sup 6} BB(bar sign) meson pairs collected with the CLEO detector, we have reconstructed B{sup 0}{yields}J/{psi}K{sub S}{sup 0}, B{sup 0}{yields}{chi}{sub c1}K{sub S}{sup 0}, and B{sup 0}{yields}J/{psi}{pi}{sup 0} decays. The latter two decay modes have been observed for the first time. We describe a K{sub S}{sup 0}{yields}{pi}{sup 0}{pi}{sup 0} detection technique and its application to the reconstruction of the decay B{sup 0}{yields}J/{psi}K{sub S}{sup 0}. Combining the results obtained using K{sub S}{sup 0}{yields}{pi}{sup +}{pi}{sup -} and K{sub S}{sup 0}{yields}{pi}{sup 0}{pi}{sup 0} decays, we determine B(B{sup 0}{yields}J/{psi}K{sup 0})=(9.5{+-}0.8{+-}0.6)x10{sup -4}, where the first uncertainty is statistical and the second one is systematic. We also obtain B(B{sup 0}{yields}{chi}{sub c1}K{sup 0})=(3.9{sub -1.3}{sup +1.9}{+-}0.4)x10{sup -4} and B(B{sup 0}{yields}J/{psi}{pi}{sup 0})=(2.5{sub -0.9}{sup +1.1}{+-}0.2)x10{sup -5}.

Abstract: The decays ${B}^{0}\ensuremath{\rightarrow}{D}^{*+}{D}^{*\ensuremath{-}},$ ${B}^{0}\ensuremath{\rightarrow}{D}^{*\ifmmode\pm\else\textpm\fi{}}{D}^{\ensuremath{\mp}}$ and ${B}^{0}\ensuremath{\rightarrow}{D}^{+}{D}^{\ensuremath{-}}$ are studied in $9.7\ifmmode\times\else\texttimes\fi{}{10}^{6} \ensuremath{\Upsilon}(4\mathrm{S})\ensuremath{\rightarrow}B\overline{B}$ decays accumulated with the CLEO detector. We determine $\mathcal{B}{(B}^{0}\ensuremath{\rightarrow}{D}^{*+}{D}^{*\ensuremath{-}}{)=(9.9}_{\ensuremath{-}3.3}^{+4.2}[\mathrm{stat}]\ifmmode\pm\else\textpm\fi{}1.2[\mathrm{syst}])\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$ and limit $\mathcal{B}{(B}^{0}\ensuremath{\rightarrow}{D}^{*\ifmmode\pm\else\textpm\fi{}}{D}^{\ensuremath{\mp}})l6.3\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$ and $\mathcal{B}{(B}^{0}\ensuremath{\rightarrow}{D}^{+}{D}^{\ensuremath{-}})l9.4\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$ at 90% confidence level (C.L.). We also perform the first angular analysis of the ${B}^{0}\ensuremath{\rightarrow}{D}^{*+}{D}^{*\ensuremath{-}}$ decay and determine that the $\mathrm{CP}$-even fraction of the final state is greater than $0.11$ at 90% C.L. Future measurements of the time dependence of these decays may be useful for the investigation of $\mathrm{CP}$ violation in neutral B meson decays.

We fitted the {psi}{sup (')}K invariant mass distributions of these B meson candidates and measured the masses of the neutral and charged B mesons to be M(B{sup 0})=5279.1{+-}0.7[stat]{+-}0.3[ syst] MeV/c{sup 2} and M(B{sup +})=5279.1{+-}0.4[stat]{+-}0.4[ syst] MeV/c{sup 2}.

Abstract: The resonant structure of the four pion final state in the decay {tau}{yields}3{pi}{pi}{sup 0}{nu}{sub {tau}} has been analyzed using 4.27 million {tau}{sup +}{tau}{sup -} pairs collected by the CLEO II experiment at the Cornell Electron Storage Ring. A partial wave analysis of the resonant structure of the {tau}{yields}3{pi}{pi}{sup 0}{nu}{sub {tau}} decay has been performed; the spectral decomposition of the four pion system is dominated by the {omega}{pi} and a{sub 1}{pi} final states. The mass and width of the {rho}{sup '} resonance have been extracted from a fit to the {tau}{yields}{omega}{pi}{nu}{sub {tau}} spectral function. We have searched for second class currents in the decay {tau}{yields}{omega}{pi}{nu}{sub {tau}} using spin-parity analysis and established an upper limit on the non-vector current contribution.

Abstract: Using the CLEO II detector operating at the Cornell Electron Storage Ring (CESR) e{sup +}e{sup -} collider, we have measured the structure functions in the decay {tau}{sup {+-}}{yields}{pi}{sup {+-}}{pi}{sup 0}{pi}{sup 0}{nu}{sub {tau}}, based on a sample corresponding to 4x10{sup 6} produced {tau}-pair events. We determine the integrated structure functions, which depend only on the three pion invariant mass, as well as the structure functions differential in the Dalitz plot variables. We extract model independent limits on non-axial-vector contributions from the measured structure functions as less than 16.6% of the total branching fraction, at the 95% confidence level. Separating the non-axial-vector contributions into scalar and vector contributions, we measure that scalars (vectors) contribute with less than 9.4% (7.3%) to the total branching fraction, at the 95% confidence level.

Abstract: Based on a sample corresponding to $4.3\ifmmode\times\else\texttimes\fi{}{10}^{6}$ produced $\ensuremath{\tau}$-pair events, we have studied hadronic dynamics in the decay ${\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\nu}}_{\ensuremath{\tau}}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}{\ensuremath{\pi}}^{0}$ in data recorded by the CLEO II detector operating at the CESR ${e}^{+}{e}^{\ensuremath{-}}$ collider. The decay is dominated by the process ${\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\nu}}_{\ensuremath{\tau}}{a}_{1}^{\ensuremath{-}}(1260),$ with the ${a}_{1}^{\ensuremath{-}}$ meson decaying to three pions predominantly via the lowest dimensional (mainly S-wave) ${\ensuremath{\rho}}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}$ Born amplitude. From model-dependent fits to the Dalitz plot and angular observables in bins of $3\ensuremath{\pi}$ mass, we find significant additional contributions from amplitudes for ${a}_{1}$ decay to $\ensuremath{\sigma}\ensuremath{\pi},$ ${f}_{0}(1370)\ensuremath{\pi},$ and ${f}_{2}(1270)\ensuremath{\pi},$ as well as higher dimensional ${a}_{1}\ensuremath{\rightarrow}\ensuremath{\rho}\ensuremath{\pi}$ and ${\ensuremath{\rho}}^{\ensuremath{'}}\ensuremath{\pi}$ amplitudes. Notably, the squared $\ensuremath{\sigma}\ensuremath{\pi}$ amplitude accounts for approximately 15% of the total ${\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\nu}}_{\ensuremath{\tau}}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}{\ensuremath{\pi}}^{0}$ rate in the models considered. The data are well described using couplings to these amplitudes that are independent of the $3\ensuremath{\pi}$ mass. These amplitudes also provide a good description for the ${\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\nu}}_{\ensuremath{\tau}}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ Dalitz plot distributions. We have searched for additional contributions from ${\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\nu}}_{\ensuremath{\tau}}{\ensuremath{\pi}}^{\ensuremath{'}}\ensuremath{-}(1300).$ We place $90%$ confidence level upper limits on the branching fraction for this channel of between $1.0\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$ and $1.9\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4},$ depending on the ${\ensuremath{\pi}}^{\ensuremath{'}}$ decay mode considered. The ${\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}{\ensuremath{\pi}}^{0}$ mass spectrum is parametrized by a Breit-Wigner form with a mass-dependent width which is specified according to the results of the Dalitz plot fits plus an unknown coupling to an ${a}_{1}\ensuremath{\rightarrow}{K}^{*}K$ amplitude. From a ${\ensuremath{\chi}}^{2}$ fit using this parametrization, we extract the pole mass and width of the ${a}_{1},$ as well as the magnitude of the ${K}^{*}K$ coupling. We have also investigated the impact of a possible contribution from the ${a}_{1}^{\ensuremath{'}}(1700)$ meson on this spectrum. Finally, exploiting the parity-violating angular asymmetry in ${a}_{1}\ensuremath{\rightarrow}3\ensuremath{\pi}$ decay, we determine the signed value of the $\ensuremath{\tau}$ neutrino helicity to be ${h}_{{\ensuremath{\nu}}_{\ensuremath{\tau}}}=\ensuremath{-}1.02\ifmmode\pm\else\textpm\fi{}0.13 (\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.03 (\mathrm{s}\mathrm{y}\mathrm{s}\mathrm{t}+\mathrm{m}\mathrm{o}\mathrm{d}\mathrm{e}\mathrm{l}),$ confirming the left-handedness of the $\ensuremath{\tau}$ neutrino.

Abstract: We present new measurements of photon energies and branching fractions for the radiative transitions {Upsilon}(2S){r_arrow}{gamma}{chi}{sub b(J=0,1,2)}(1P). The masses of the {chi}{sub b} states are determined from the measured radiative photon energies. The ratio of mass splittings between the {chi}{sub b} substates, r{equivalent_to}(M{sub J=2}{minus}M{sub J=1})/(M{sub J=1}{minus}M{sub J=0}), with M the {chi}{sub b} mass, provides information on the nature of the b{bar b} confining potential. We find r(1P)=0.542{plus_minus}0.022{plus_minus}0.024. This value is somewhat lower than the previous world average, but more consistent with the theoretical expectation that r(1P){lt}r(2P); i.e., that this mass splitting ratio is smaller for the {chi}{sub b}(1P) states than for the {chi}{sub b}(2P) states. {copyright} {ital 1999} {ital The American Physical Society}

Abstract: Using a data sample with integrated luminosity of about 3.9 fb^{-1} collected in e+ e- annihilation with the CLEO-II detector at the Cornell Electron Storage Ring, we have measured the branching ratios for the decay modes Ds -> (eta, eta') pi and Ds -> (eta, eta') rho relative to Ds -> phi pi. These decay modes are among the most common hadronic decays of the Ds's and can be related by factorization to the semileptonic decays Ds -> (eta,eta') l nu. The results obtained are compared with previous CLEO results and with the branching ratios measured for the related semileptonic decays. We also report results on the Cabibbo-suppressed decays of the D+ to the same final states.

Abstract: A measurement of the spin alignment of charged D^* mesons produced in continuum e^+ e^- \to c \bar{c} events at \sqrt{s}=10.5 GeV is presented. This study using 4.72 fb^{-1} of CLEO II data shows that there is little evidence of any D^* spin alignment.

Abstract: Using data collected by the CLEO II detector at the center-of-mass energy on or near the Upsilon(4S) resonance, we have determined the 90% confidence level upper limit B(Bbar --> Lambda_c^+ e- X)/B(Bbar --> Lambda_c^+ X, Lambdabar_c^- X) < 0.05 for electrons with momentum above 0.6 GeV/c. We have also derived the ratio B(B^- --> Lambda_c^+ pbar e- nubar_e)/B(Bbar --> Lambda_c^+ pbar X) < 0.04 at the 90% confidence level and measured the ratio B(Bbar --> Lambda_c^+ pbar X)/B(Bbar --> Lambda_c^+ X, Lambdabar_c^- X) = 0.57 +- 0.05 +- 0.05., 9 page postscript file, postscript file also available through http://w4.lns.cornell.edu/public/CLNS
