Abstract: Results are reported on a high statistics study of Bhabha scattering at 29 GeV in the polar angle region, |cos θ| < 0.55. The data are consistent with the standard model, and measure vector and axial-vector coupling constants of gv2 = 0.03 ± 0.09 and ga2 = 0.46±0.14. Limits on the QED-cutoff parameters are Λ+ > 154 GeV and Λ- > 220 GeV. Lower limits on scale parameters of composite models are in the range 0.9-2.8 TeV. The partial width of a hypothetical spin-zero boson decaying to e+e- has an upper limit which varies from 6 to 57 MeV corresponding to a boson mass in the range 45-80 GeV/c2. © 1986.

Abstract: We report results of searches for charmless hadronic B meson decays to pseudoscalar(pi^+-,K^+-,Pi^0 or Ks^0)-vector(Rho, K* or Omega) final states. Using 9.7 million BBbar pairs collected with the CLEO detector, we report first observation of B^- --> Pi^-Rho^0, B^0 --> Pi^+-Rho^-+ and B^- --> Pi^-Omega, which are expected to be dominated by hadronic b --> u transitions. The measured branching fractions are (10.4+3.3-3.4+-2.1)x10^-6, (27.6+8.4-7.4+-4.2)x10^-6 and (11.3+3.3-2.9+-1.4)x10^-6, respectively. Branching fraction upper limits are set for all the other decay modes investigated., 10 pages postscript, also available through http://w4.lns.cornell.edu/public/CLNS

Abstract: The charged particle multiplicity distribution for e+e− annihilations at s = 29 GeV has been measured using the High Resolution Spectrometer at PEP. The multiplicity distribution, expressed as a function of the mean, shows KNO scaling when compared to e+e− data at other energies. Multiplicity distributions for particles selected in different central rapidity spans are presented. All of these are well presented by the Negative binomial distribution. As the rapidity span is narrowed, the distributions become broader and approach a constant value of the parameter k.

Abstract: We have measured the first and second moments of the hadronic mass-squared distribution in B -> X_c l nu, for P(lepton) > 1.5 GeV/c. We find = 0.251 +- 0.066 GeV^2, < (M_X^2 -)^2 > = 0.576 +- 0.170 GeV^4, where M_D[Bar] is the spin-averaged D meson mass. From that first moment and the first moment of the photon energy spectrum in b -> s gamma, we find the HQET parameter lambda_1 (MS[Bar], to order 1/M^3 and beta_0 alpha_s^2) to be -0.24 +- 0.11 GeV^2. Using these first moments and the B semileptonic width, and assuming parton-hadron duality, we obtain |V_cb| = 0.0404 +- 0.0013., Comment: 11 pages postscript, also available through http://w4.lns.cornell.edu/public/CLNS, submitted to PRL

Abstract: The production of neutral K∗(890) and ρ0 mesons was studied in e+e− annihilation at s =29 GeV using the High Resolution Spectrometer at PEP. Differential cross sections are presented as a function of the scaled energy variable z and compared to π0 and K0 production. The measured multiplicities are 0.84±0.08 ϱ0 mesons and 0.57±0.09 K ∗0 (890) mesons per event for a meson momentum greater than 725 MeV/c. The ratios of vector meson to pseudoscalar meson production for (u,d), s and c quark are compared to predictions of the Lund model.

Abstract: We present a new determination of the Ds decay constant, f_{Ds} using 5 million continuum charm events obtained with the CLEO II detector. Our value is derived from our new measured ratio of widths for Ds -> mu nu/Ds -> phi pi of 0.173+/- 0.021 +/- 0.031. Taking the branching ratio for Ds -> phi pi as (3.6 +/- 0.9)% from the PDG, we extract f_{Ds} = (280 +/- 17 +/- 25 +/- 34){MeV}. We compare this result with various model calculations., 23 page postscript file, postscript file also available through http://w4.lns.cornell.edu/public/CLNS

Abstract: Separate samples of charm quark and light quark (u, d, s) jets have been isolated in an experiment studying e+e− annihilations at s = 29 GeV . The results come from data corresponding to an integrated luminosity of 111 pb−1 collected by the High Resolution Spectrometer. Differences were observed in charged multiplicities, momentum distributions, and rapidity of the size expected from the different fragmentation functions and leading particle decay properties of the two samples.

Abstract: Using 13.4 $fb^{-1}$ of data collected with the CLEO detector at the Cornell Electron Storage Ring, we have observed 300 events for the two-photon production of ground-state pseudo-scalar charmonium in the decay $\eta_c$ -> $K_S K^{\mp} \pi^{\pm}$. We have measured the $\eta_c$ mass to be (2980.4 +- 2.3 (stat) +- 0.6 (sys)) MeV and its full width as (27.0 +- 5.8 (stat) +- 1.4 (sys)) MeV. We have determined the two-photon partial width of the $\eta_c$ meson to be (7.6 +- 0.8 (stat) +- 0.4 (sys) +- 2.3 (br)) keV, with the last uncertainty associated with the decay branching fraction.

Abstract: Using the CLEO~II detector, we have measured the differential cross sections for exclusive two-photon production of light pseudoscalar mesons $\pi^0$, $\eta$, and $\eta^{\prime}$. From our measurements we have obtained the form factors associated with the electromagnetic transitions $\gamma^*\gamma$ $\to$ meson. We have measured these form factors in the momentum transfer ranges from 1.5 to 9, 20, and 30 GeV$^2$ for $\pi^0$, $\eta$, and $\eta^{\prime}$, respectively, and have made comparisons to various theoretical predictions., Comment: 30 page postscript file, postscript file also available through http://w4.lns.cornell.edu/public/CLNS

Abstract: We have measured the charge asymmetry in like-sign dilepton yields from B(0)B*(0) meson decays using the CLEO detector at the Cornell Electron Storage Ring. We find a(0)(ll) identical with[N(l(+)l(+))-N(l(-)l(-))]/[N(l(+)l(+))+N(l(-)l(-))] = +0.013+/-0.050+/-0.005. We combine this result with a previous, independent measurement and obtain Re(epsilon(B))/(1+ the absolute value of epsilon(B)(2)) = +0.0035+/-0.0103+/-0.0015 (uncertainties are statistical and systematic, respectively) for the CP impurity parameter, epsilon(B).

Abstract: Using 13.7 $fb^{-1}$ of data recorded by the CLEO detector at CESR, we report evidence for two new charmed baryons: one decaying into $\Xi_c^{0 \prime}\pi^+$ with the subsequent decay $\Xi_c^{0 \prime} \to \Xi_c^0 \gamma$, and its isospin partner decaying into $\Xi_c^{+ \prime} \pi^-$ followed by $\Xi_c^{+\prime} \to \Xi_c^+\gamma$. We measure the following mass differences for the two states: $M(\Xi_c^0 \gamma \pi^+)-M(\Xi_c^0)$=318.2+-1.3+-2.9 MeV, and $M(\Xi_c^+ \gamma \pi^-)-M(\Xi_c^+)$=324.0+-1.3+-3.0 MeV. We interpret these new states as the $J^P = 1/2^- \Xi_{c1}$ particles, the charmed-strange analogs of the $\Lambda_{c1}^+(2593)$.

Abstract: We have studied two-body charmless hadronic decays of B mesons into the final states straight phiK and phiK(*). Using 9.7 million BB pairs collected with the CLEO II detector, we observe the decays B- --> phiK- and B0--> phiK(*0) with the following branching fractions: B(B--->phiK-) = (5.5(+2.1)(-1.8)+/-0.6)x10(-6) and B(B0--> phiK(*0)) = (11.5(+4.5+1.8)(-3.7-1.7))x10(-6). We also see evidence for the decays B0-->phiK0 and B---> phiK(*-). However, since the statistical significance is not overwhelming for these modes, we determine upper limits of

Abstract: We report the first observation of exclusive decays of the type B-->D(*)N_NX, where N is a nucleon. Using a sample of 9.7x10(6)B_B pairs collected with the CLEO detector operating at the Cornell Electron Storage Ring, we measure the branching fractions B(B0-->D(*-)p_p pi(+)) = (6.5(+1.3)(-1.2)+/-1.0)x10(-4) and B(B0-->D(*-)p_n) = (14.5(+3.4)(-3.0)+/-2.7)x10(-4). Antineutrons are identified by their annihilation in the CsI electromagnetic calorimeter.

Abstract: We analyze 9.7x10(6) B_B pairs recorded with the CLEO detector to determine the production ratio of charged to neutral B-meson pairs produced at the Upsilon(4S) resonance. We measure the rates for B0-->J/psiK((*)0) and B+-->J/psiK((*)+) decays and use the world-average B-meson lifetime ratio to extract the relative widths f(+-) / f(00) = gamma(Upsilon(4S)-->B+B-) / gamma(Upsilon(4S)-->B0 B-0)) = 1.04+/-0.07(stat)+/-0.04(syst). With the assumption that f(+-)+f(00) = 1, we obtain f(00) = 0.49+/-0.02(stat)+/-0.01(syst) and f(+-) = 0.51+/-0.02(stat)+/-0.01(syst). This production ratio and its uncertainty apply to all exclusive B-meson branching fractions measured at the Upsilon(4S) resonance.

Abstract: In a sample of $9.66\times 10^6 B\bar{B}$ pairs collected with the CLEO detector we make the first observation of B decays to an $\eta_c$ and a kaon. We measure branching fractions $BR(B^+\to\eta_c K^+) = (0.69 + 0.26 - 0.21 +- 0.08 +- 0.20)\times 10^{-3}$ and $BR(B^0\to\eta_c K^0) = (1.09 + 0.55 - 0.42 +- 0.12 +- 0.31)\times 10^{-3}$, where the first error is statistical, the second is systematic and the third is from the $\eta_c$ branching fraction uncertainty. From these we extract the $\eta_c$ decay constant in the factorization approximation, $f_{\eta_c} = 335 +- 75$ MeV. We also search for B decays to a $\chi_{c0}$ and a kaon. No evidence for a signal is found and we set 90% CL upper limits: $BR(B^+\to\chi_{c0} K^+) < 4.8\times 10^{-4}$ and $BR(B^0\to\chi_{c0} K^0) < 5.0\times 10^{-4}$.

Abstract: We have studied charmless hadronic decays of B mesons into two-body final states with kaons and pions and observe three new processes with the following branching fractions: B(B{yields}{pi}{sup +}{pi}{sup -})=(4.3{sup +1.6}{sub -1.4}{+-}0.5)x10{sup -6} , B(B{yields}K{sup 0}{pi}{sup 0}) =(14.6{sup +5.9+2.4}{sub -5.1-3.3})x 10{sup -6} , and B(B{yields}K{sup {+-}}{pi}{sup 0} )=(11.6{sup +3.0+1.4}{sub -2.7-1.3}) x10{sup -6} . We also update our previous measurements for the decays B{yields}K{sup {+-}}{pi}{sup {+-}} and B{sup {+-}}{yields}K{sup 0}{pi}{sup {+-}} . (c) 2000 The American Physical Society.

Abstract: We search for CP-violating asymmetries (Acp) in the B meson decays to K+- pi-+, K+- pi0, Ks pi+-, K+- eta', and omega pi+-. Using 9.66 million Upsilon(4S) decays collected with the CLEO detector, the statistical precision on Acp is in the range of \pm 0.12 to \pm 0.25 depending on decay mode. While CP-violating asymmetries of up to \pm 0.5 are possible within the Standard Model, the measured asymmetries are consistent with zero in all five decay modes studied., 10 pages, 3 figures

Abstract: We report results of a search for the rare radiative decay B(bar sign){sup 0}{yields}D{sup *0} {gamma} . Using 9.66x10{sup 6} BB(bar sign) meson pairs collected with the CLEO detector at the Cornell Electron Storage Ring, we set an upper limit on the branching ratio for this decay of 5.0x10{sup -5} at 90% C.L. This provides evidence that the anomalous enhancement is absent in W -exchange processes and that weak radiative B decays are dominated by the short-distance b{yields}s{gamma} mechanism in the standard model.

Abstract: We have searched for the rare decays of the eta prime meson to e+ e- eta, e+ e- pizero, e+ e- gamma, and e mu in hadronic events at the CLEO II detector. The search is conducted on 4.80 fb^-1 of e+ e- collisions at the Cornell Electron Storage Ring. We find no signal in any of these modes, and set 90% confidence level upper limits on their branching fractions of 2.4 X 10^-3, 1.4 X 10^-3, 0.9 X 10^-3, and 4.7 X 10^-4, respectively. We also investigate the Dalitz plot of the common decay of the eta prime to pi+ pi- eta. We fit the matrix element with the Particle Data Group parameterization and find Re(alpha) = -0.021 +- 0.025, where alpha is a linear function of the kinetic energy of the eta.

Abstract: Using 13.7 fb(-1) of data recorded by the CLEO detector at Cornell Electron Storage Ring, we report evidence of two new charmed baryons: one decaying into Xi(0')(c)pi(+) with the subsequent decay Xi(0')(c)-->Xi(0)(c)gamma, and its isospin partner decaying into Xi(+')(c)pi(-) followed by Xi(+')(c)-->Xi(+)(c)gamma. We measure the following mass differences for the two states: M(Xi(0)(c)gammapi(+))-M(Xi(0)(c)) = 318.2+/-1.3+/-2.9 MeV and M(Xi(+)(c)gammapi(-))-M(Xi(+)(c)) = 324.0+/-1.3+/-3.0 MeV. We interpret these new states as the J(P) = 1 / 2(-) Xi(c1) particles, the charmed-strange analogs of the Lambda(+)(c1)(2593).

Abstract: Using a sample of $3.3\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B$-meson decays collected with the CLEO detector at the Cornell Electron Storage Ring, we have studied ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}^{0}{\ensuremath{\ell}}^{\ensuremath{-}}\overline{\ensuremath{\nu}}$ and ${\overline{B}}^{0}\ensuremath{\rightarrow}{D}^{+}{\ensuremath{\ell}}^{\ensuremath{-}}\overline{\ensuremath{\nu}}$ decays, where ${\ensuremath{\ell}}^{\ensuremath{-}}$ can be either ${e}^{\ensuremath{-}}$ or ${\ensuremath{\mu}}^{\ensuremath{-}}$. We distinguish $B\ensuremath{\rightarrow}D\ensuremath{\ell}\ensuremath{\nu}$ from other $B$ semileptonic decays by examining the net momentum and energy of the particles recoiling against $D\ensuremath{-}\ensuremath{\ell}$ pairs. We find $\ensuremath{\Gamma}(B\ensuremath{\rightarrow}D\ensuremath{\ell}\ensuremath{\nu})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}(14.1\ifmmode\pm\else\textpm\fi{}1.0\ifmmode\pm\else\textpm\fi{}1.2){\mathrm{ns}}^{\ensuremath{-}1}$ and derive branching fractions for ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}^{0}{\ensuremath{\ell}}^{\ensuremath{-}}\overline{\ensuremath{\nu}}$ and ${\overline{B}}^{0}\ensuremath{\rightarrow}{D}^{+}{\ensuremath{\ell}}^{\ensuremath{-}}\overline{\ensuremath{\nu}}$ of $(2.32\ifmmode\pm\else\textpm\fi{}0.17\ifmmode\pm\else\textpm\fi{}0.20)%$ and $(2.20\ifmmode\pm\else\textpm\fi{}0.16\ifmmode\pm\else\textpm\fi{}0.19)%$, respectively, where the uncertainties are statistical and systematic. We also investigate the $B\ensuremath{\rightarrow}D\ensuremath{\ell}\ensuremath{\nu}$ form factor and the implication of the result for $|{V}_{\mathrm{cb}}|$.

Abstract: We have observed four fully reconstructed B{sup 0}{r_arrow}D{sup {asterisk}+}D{sup {asterisk}{minus}} candidates in 5.8{times}10{sup 6} {Upsilon}(4S){r_arrow}B{ovr B} decays recorded with the CLEO detector. The background is estimated to be 0.31{plus_minus}0.10 thinspthinspevents. The probability that the background could produce four or more signal candidates with the observed distribution among D{sup {asterisk}+} and D{sup {asterisk}{minus}} decay modes is 1.1{times}10{sup {minus}4} . The measured decay rate, B(B{sup 0}{r_arrow}D{sup {asterisk}+}D{sup {asterisk} {minus}})=[6.2{sup +4.0}{sub {minus}2.9}( stat){plus_minus}1.0(syst) ]{times}10{sup {minus}4} , is large enough for this decay mode to be of interest for the measurement of a time-dependent CP asymmetry. {copyright} {ital 1999} {ital The American Physical Society}

We interpret the observed signals as the {Xi}{sup +{prime}}{sub c}thinsp( c{l_brace}su{r_brace}) and {Xi}{sup 0{prime}}{sub c}thinsp( c{l_brace}sd{r_brace}) , the symmetric partners of the well-established antisymmetric {Xi}{sup +}{sub c}thinsp(c[ su]) and {Xi}{sup 0}{sub c}thinsp(c[ sd]) . The mass differences M({Xi}{sup +{prime}}{sub c}){minus}M( {Xi}{sup +}{sub c}) and M({Xi}{sup 0{prime}}{sub c}){minus}M( {Xi}{sup 0}{sub c}) have been measured to be 107.8{plus_minus}1.7{plus_minus}2.5 and 107.0{plus_minus}1.4{plus_minus}2.5 MeV /c{sup 2} , respectively. {copyright} {ital 1999} {ital The American Physical Society }

Abstract: The decay {tau}{sup {minus}}{r_arrow}K{sup {asterisk}{minus}}{eta}{nu}{sub {tau}} has been observed with the CLEOthinspthinspII detector. The K{sup {asterisk}{minus}} is reconstructed in two decay channels, K{sup {asterisk}{minus}}{r_arrow}K{sub S}{pi}{sup {minus}}{r_arrow} {pi}{sup {minus}}{pi}{sup +}{pi}{sup {minus}} and K{sup {asterisk}{minus}}{r_arrow}K{sup {minus}}{pi}{sup 0} . The {eta} is reconstructed from the decay {eta}{r_arrow}{gamma}{gamma} . The measured branching fraction is B({tau}{sup {minus}}{r_arrow}K{sup {asterisk}{minus}} {eta}{nu}{sub {tau}})=(2.9{plus_minus} 0.8{plus_minus}0.4){times}10{sup {minus}4} . We also measure the inclusive branching fractions without requiring the K{sup {asterisk}} resonance, B({tau}{sup {minus}}{r_arrow}K{sub S}{pi}{sup {minus}}{eta}{nu}{sub {tau}})=(1.10 {plus_minus}0.35{plus_minus}0.11){times}10{sup {minus}4} and B({tau}{sup {minus}}{r_arrow}K{sup {minus}}{pi}{sup 0}{eta}{nu}{sub {tau}})=(1.77 {plus_minus}0.56{plus_minus}0.71){times}10{sup {minus}4} . The results indicate that the K{sup {asterisk}{minus}} resonance dominates the K{sub S}{pi}{sup {minus}} mass spectrum. {copyright} {ital 1999} {ital The American Physical Society}

No evidence for a signal is found in 4.77fb−1 of data and a 95% C.L. upper limit on [τγγBπ+π−]fJ(2220) of 2.5 eV is set. If this result is combined with the BES Collaboration's measurement of fJ(2220)→π+π− in radiative J/Ψ decay and the recent CLEO result for [τγγBK0SK0S]fJ(2220), a 95% C.L. lower limit on the stickiness of 102 is obtained. This result for the stickiness provides further support for a substantial neutral parton content in the fJ(2220). © 1998 The American Physical Society.

We discuss the physical interpretation of the signal, including the possibility that it is due to b{r_arrow}sg{sup {asterisk}} transitions.

Abstract: We have searched for two-body charmless decays of B mesons to purely hadronic exclusive final states including $\omega$ or $\phi$ mesons using data collected with the CLEO II detector. With this sample of $6.6 \times 10^6$ B mesons we observe a signal for the $\omega K^+$ final state, and measure a branching fraction of B($B^+ \to \omega K^+$) = 1.5 +0.7 -0.6 +-0.2 $\times 10^{-5}$. We also observe some evidence for the $\phi K^*$ final state, and upper limits are given for 22 other decay modes. These results provide the opportunity for studies of theoretical models and physical parameters.

Abstract: We have observed a signal for the decay D^(*+)→D^+γ at a significance of 4 standard deviations. From the measured branching ratio B(D^(*+)→D^+γ)/B(D^(*+)→D^+π^0) = 0.055±0.014±0.010 we find B(D^(*+)→D^+γ) = 0.017±0.004±0.003, where the first uncertainty is statistical and the second is systematic. We also report the highest precision determination of the remaining D^(*+) branching fractions.

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: In a sample of 6.6×10^6 produced B mesons we have observed decays B→η′K, with branching fractions B(B^+→η′K^+) = (6.5_(-1.4)^(+1.5)±0.9)×10^(-5) and B(B^0→η′K^0) = (4.7_(-2.0)^(+2.7)±0.9)×10^(-5). We have searched with comparable sensitivity for 17 related decays to final states containing an η or η′ meson accompanied by a single particle or low-lying resonance. Our upper limits for these constrain theoretical interpretations of the B→η′K signal.

With data collected by the CLEO II detector at the Cornell Electron Storage Ring, we have determined B(D^0→K^-π^+) = [3.81±0.15(stat)±0.16(syst)]%.

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: The decays ϒ(4S)→BB , followed by B→D^*π and D^*→Dπ, permit reconstruction of all kinematic quantities that describe the sequence without reconstruction of the D, with reasonably low backgrounds. Using an integrated e^+e^- luminosity of 3.1 fb^(-1) accumulated at the ϒ(4S) by the CLEO-II detector, we report measurements of B(B ^0→D^(*+)π^-) = (2.81±0.11±0.21±0.05)×10^(-3) and B(B-→D^*0π^-) = (4.34±0.33±0.34±0.18)×10^(-3).

Abstract: Using data taken with the CLEO II detector at the Cornell Electron Storage Ring, we present the first full angular analysis in the color-suppressed modes B{sup 0}{r_arrow}J/{psi}K{sup *0} and B{sup +}{r_arrow}J/{psi}K{sup *+}. This leads to a complete determination of the decay amplitudes of these modes including the longitudinal polarization {Gamma}{sub L}/{Gamma}=0.52{plus_minus}0.07{plus_minus}0.04 and the P wave component {vert_bar}P{vert_bar}{sup 2}=0.16{plus_minus}0.08{plus_minus}0.04. In addition, we update the branching fractions for B{r_arrow}J/{psi}K and B{r_arrow}J/{psi}K{sup *}. {copyright} {ital 1997} {ital The American Physical Society}
