Abstract: We report here the status of the CLEO III silicon vertex detector electronics. The CLEO III silicon detector is a 4-layer barrel-style device which spans 93% of the solid angle observing the interaction region. All layers will be constructed with double-sided silicon. The innermost layer must be able to handle large singles rates associated with a detector situated near the interaction region. In order to cover the required solid angle, the outermost layer is 55 cm long and presents a large capacitive load to the front-end electronics. The electronics chain chosen to meet this challenge consists of a low noise cascode preamplifier followed by an ADC on each channel. The system issues will be described herein together with the chosen solutions, noise performance of each subsystem prototype, and expected results of the full system.

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 data taken with the CLEO II detector, we have studied the decays of the ${D}^{0}$ to ${K}^{+}{K}^{\ensuremath{-}}$, ${K}^{0}{\overline{K}}^{0}$, ${K}_{S}^{0}{K}_{S}^{0}{K}_{S}^{0}$, ${K}_{S}^{0}{K}_{S}^{0}{\ensuremath{\pi}}^{0}$, ${K}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}$. We present significantly improved results for $B({D}^{0}\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}})=(0.454\ifmmode\pm\else\textpm\fi{}0.028\ifmmode\pm\else\textpm\fi{}0.035)%$, $B({D}^{0}\ensuremath{\rightarrow}{K}^{0}{\overline{K}}^{0})=(0.054\ifmmode\pm\else\textpm\fi{}0.012\ifmmode\pm\else\textpm\fi{}0.010)%$, and $B({D}^{0}\ensuremath{\rightarrow}{K}_{S}^{0}{K}_{S}^{0}{K}_{S}^{0})=(0.074\ifmmode\pm\else\textpm\fi{}0.010\ifmmode\pm\else\textpm\fi{}0.015)%$, where the first errors are statistical and the second errors are the estimate of our systematic uncertainty. We also present a new upper limit $B({D}^{0}\ensuremath{\rightarrow}{K}_{S}^{0}{K}_{S}^{0}{\ensuremath{\pi}}^{0})l0.059%$ at the 90% confidence level and the first measurement of $B({D}^{0}\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{0})=(0.14\ifmmode\pm\else\textpm\fi{}0.04)%$.

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: A feasibility study of using silica aerogel as a radiator in a threshold Cherenkov counter was done in preparation for an upgrade of the CLEO detector at CESR. The detector design requires separation of kaons from pions in the momentum range of 0.7–2.8 GeV/ c with statistical resolving power of 10 −4 and ability to operate the device in a 1.5 T magnetic field. This note summarizes the results of an R&D and simulation studies as well as a conceptual design that satisfies such requirements.

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 .

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: We have observed two new decay modes of the charmed baryon $\Xi_c^+$ into $\Sigma^+ K^-\pi^+$ and $\Sigma^+ \bar{K}^{*0}$ using data collected with the CLEO II detector. We also present the first measurement of the branching fraction for the previously observed decay mode $\Xi_c^+\to\Lambda K^-\pi^+\pi^+$. The branching fractions for these three modes relative to $\Xi_c^+\to\Xi^-\pi^+\pi^+$ are measured to be $1.18 \pm 0.26 \pm 0.17$, $0.92 \pm 0.27 \pm 0.14$, and $0.58 \pm 0.16 \pm 0.07$, respectively.

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: We have measured the weak decay asymmetry parameters ($\aLC $) for two \LC\ decay modes. Our measurements are $\aLC = -0.94^{+0.21+0.12}_{-0.06-0.06} $ for the decay mode $\Lambda_c^+ \to \Lambda\pi^+ $ and $\aLC = -0.45\pm 0.31 \pm 0.06$ for the decay mode $\Lambda_c \to \Sigma^+\pi^0 $. By combining these measurements with the previously measured decay rates, we have extracted the parity-violating and parity-conserving amplitudes. These amplitudes are used to test models of nonleptonic charmed baryon decay.

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.

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.

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: We have found the first evidence for the Cabibbo suppressed, color suppressed decay B − → ψπ − in a data sample of 4 million B decays obtained by the CLEO detector at the Cornell Electron Storage Ring (CESR). The branching ratio is found to be (4.3±2.3)% of the Cabibbo allowed B − → ψK − decay mode, which is consistent with theoretical expectations.

Abstract: We have studied the leptonic decay of the $\Upsilon (1S)$ resonance into tau pairs using the CLEO II detector. A clean sample of tau pair events is identified via events containing two charged particles where exactly one of the particles is an identified electron. We find $B(\Upsilon(1S) \to \tau^+ \tau^-) = (2.61~\pm~0.12~{+0.09\atop{-0.13}})%$. The result is consistent with expectations from lepton universality.

Abstract: Using the CLEO II detector at CESR, we have observed two charmed states, where the higher mass state decays to D0π+ and to D ∗0 π + , while the lower mass state decays to D ∗0 π + , but not to D0π+. The masses and widths were measured to be 2425±2±2 MeV/c2 and 26−7−4+8+4 MeV/c2 for the lower mass state, and 2463±3±3 MeV/c2 and 27−8−5+11+5 MeV/c2 for the higher mass state. Properties of these states, including their decay angular distributions and spin-parity assignments have been studied. The results of this analysis support the identification of these states as the charged L = 1 D 1 (2420) + and D 2 ∗ (2460) + , respectively. The isospin mass splittings between these states and their neutral partners have also been measured. This is the first full reconstruction of any decay mode of the D1 (2420)+ and the first observation of the decay of D 2 ∗ (2460) + to D ∗0 π + .

Abstract: The dynamics of the decay D s + → φe + v e are studied using a sample of 474 events recorded by the CLEO II detector. A three dimensional fit to the decay angles and q 2 is performed to extract the ratios of form factors R 2 = A 2 (0)/ A 1 (0) and R v = V (0 )/ A 1 (0), where A 1 (0) and A 2 (0) are the two axial vector form factors and V (0) is the vector form factor evaluated at q 2 =0. By assuming the single pole parameterization for the form factors, we obtain: R 2 =1.4±0.5±0.3 and R v =0.9±0.6±0.3.

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.

Abstract: We have observed the previously unseen decay modes Λπ+π0, Σ0π+π0 and Σ0π−π+π+ of the charmed baryon Λc+, as well as Λc+→Σ0π+ observed previously by ARGUS. The branching ratios for these four decay modes relative to Λc+→pK−π+ are measured to be 0.73 ±0.09± 0.16, 0.36 ±0.09±0.10, 0.21±0.05±0.05, and 0.21±0.02 ±0.04, respectively. Using the recent CLEO measurement of the branching ratio for Λc+→pK− π+, these modes account for 6% of Λc+ decays.

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 at CESR, we have measured the ratio of branching fractions B (D + S → φl + ν) B (D + S → φπ + ) = 0.54 ± 0.05 ± 0.04 . We use this measurement to obtain a model dependent estimate of B (D + S → φπ + ) .
