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 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: 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

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 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 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 + ) .

Abstract: Using the CLEO II detector at CESR we observe 500 Λ l + pairs consistent with the semileptonic decay Λc+ → λ+ν We measure σ(e + e − → Λ + c X) · B(Λ + c → Λ l + ν l ) = 4.77±0.25±0.66 pb . Combining with the charm semileptonic width and the lifetime of the Λc we also obtain B(Λ+c → pK−π+). We find no evidence for Λ l + ν l final states in which there are additional Λ+c decay products. We measure the decay asymmetry parameter of Λ+c → Λe+νe to be αΛc = −0.89+0.17+0.09−0.11−0.05.

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

We find 90% confidence level upper limits on the branching fractions, ${\mathit{B}}_{\mathrm{\ensuremath{\pi}}\mathrm{\ensuremath{\pi}}}$2.9\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}5}$, ${\mathit{B}}_{\mathit{K}\mathrm{\ensuremath{\pi}}}$2.6\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}5}$, and ${\mathit{B}}_{\mathit{K}\mathit{K}}$0.7\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}5}$. While there is no statistically significant signal in the individual modes, the sum of ${\mathit{B}}_{\mathrm{\ensuremath{\pi}}\mathrm{\ensuremath{\pi}}}$ and ${\mathit{B}}_{\mathit{K}\mathrm{\ensuremath{\pi}}}$ exceeds zero with a significance of more than 4 standard deviations, indicating that we have observed charmless hadronic B decays.

Abstract: Using 1.16 × 106 B B events collected at the γ(4S) resonance by the CLEO Collaboration at the Cornell Electron Storage Ring (CESR), we have searched for decays of B mesons to exclusive two-body hadronic final states including a Ds+ or a D s ∗+ meson. We obtain the 90% confidence level upper limit β (B → D s (∗)+ π − + D s ∗ +p − + D s (∗)+ π 0 + D s (∗)+ η + D s (∗)+ p 0 + D s (∗)+ (ω) × β(D s + → φπ + ) −5 . We have also searched for the W-exchange decays, B 0 → D s (∗)− K (∗)+ .

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

We also make a precise measurement of the vector form factor for the decay D 0 → K − l + ν , using a sample of 2700 events.

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

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

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

Abstract: Using the CLEO-II detector at CESR, we have observed the Ds1(2536)+ in the decay modes D s1 + →D ∗0 K + and D ∗+ K S + , and measured its fragmentation and production ratios. Using the helicity angle distribution of the daugter D ∗0 , we obtain new evidence for the assignment of 1+ for the spin and parity of the Ds1+. We also set upper limits on the decays D s1 + →D s ∗+ λ, D 0 K + and D+Ks0.

Abstract: With the CLEO-II detector at the Cornell Electron Storage Ring, we have measured branching fractions for tau lepton decay into one-prong final states with multiple [pi][sup 0]'s [ital B][sub [ital h][ital n][pi]][sup 0], normalized to the branching fraction for tau decay into one charged particle and a single [pi][sup 0]. We find [ital B][sub [ital h]2[pi]][sup 0]/[ital B][sub [ital h][pi]][sup 0]=0.345[plus minus]0.006[plus minus]0.016, [ital B][sub [ital h]3[pi]][sup 0]/[ital B][sub [ital h][pi]][sup 0]=0.041 [plus minus]0.003[plus minus]0.005, and [ital B][sub [ital h]4[pi]][sup 0]/[ital B][sub [ital h][pi]][sup 0]=0.006[plus minus]0.002[plus minus]0.002.

Abstract: A search for the lepton mumber violating decay of the [tau] lepton to the [gamma][mu] final state has been performed with the CLEO II detector at the Cornell [ital e][sup +][ital e[minus]] storage ring CESR. In a data sample that corresponds to an integrated luminosity of 1.55 fb[sup [minus]1], we observe no candidates in the signal region. We thus determine an upper limit of [ital B]([tau][sup [minus]][r arrow][gamma][mu][sup [minus]])[lt]4.2[times]10[sup [minus]6] at 90% confidence level.

Abstract: The tau lepton electron branching fraction has been measured with the CLEO II detector at the Cornell Electron Storage Ring as [ital B][sub [ital e]]=0.1749[plus minus]0.0014[plus minus]0.0022, with the first error statistical and the second systematic. The measurement involves counting electron-positron annihilation events in which both taus decay to electrons, and normalizing to the number of tau-pair decays expected from the measured luminosity. Detected photons in these events constitute a definitive observation of tau decay radiation.

Abstract: The decay [tau][sup [minus]][r arrow][nu][sub [tau]][pi][sup [minus]][pi][sup 0][eta] has been observed for the first time using the CLEO-II detector at the Cornell Electron Storage Ring. The measured branching ratio (0.17[plus minus]0.02[plus minus]0.02)%, agrees with the CVC (conserved vector current) prediction based on [ital e][sup +][ital e[minus]][r arrow][pi][sup +][pi][sup [minus]][eta] data. Upper limits on the branching ratios for other [tau] decays to final states including [eta] mesons are improved by an order of magnitude compared to previous measurements.

Abstract: Using the CsI calorimeter of the CLEO-II detector, we have studied exclusive radiative decays of the ϒ(3S) to the χ (2P) states where the final state consists of two photons and two leptons (e + e − or μ + μ − , from either the ϒ(1S) or ϒ(2S)). We observe and measure branching ratios for the J =2 and J =1 χ b (2 3 P J ) states, and set upper limits for the J =0 state.

Abstract: Using the decay modes, ${\mathit{D}}^{\mathrm{*}+}$\ensuremath{\rightarrow}${\mathit{D}}^{+}$${\mathrm{\ensuremath{\pi}}}^{0}$ and ${\mathit{D}}^{\mathrm{*}0}$\ensuremath{\rightarrow}${\mathit{D}}^{0}$${\mathrm{\ensuremath{\pi}}}^{0}$, we have measured the ${\mathit{D}}^{\mathrm{*}+\mathrm{\ensuremath{-}}}$${\mathit{D}}^{+}$ and ${\mathit{D}}^{\mathrm{*}0\mathrm{\ensuremath{-}}}$${\mathit{D}}^{0}$ mass differences to be 140\ifmmode\pm\else\textpm\fi{}0.08\ifmmode\pm\else\textpm\fi{}0.06 and 142.12\ifmmode\pm\else\textpm\fi{}0.05\ifmmode\pm\else\textpm\fi{}0.05 MeV, respectively. Combining these measurements with the Particle Data Group average for the ${\mathit{D}}^{\mathrm{*}+\mathrm{\ensuremath{-}}}$${\mathit{D}}^{0}$ mass difference, we obtain isospin mass splittings for ${\mathit{D}}^{\mathrm{*}+\mathrm{\ensuremath{-}}}$Dusp*0 and ${\mathit{D}}^{+\mathrm{\ensuremath{-}}}$${\mathit{D}}^{0}$ of 3.32\ifmmode\pm\else\textpm\fi{}0.08\ifmmode\pm\else\textpm\fi{}0.05 and 4.80\ifmmode\pm\else\textpm\fi{}0.10 \ifmmode\pm\else\textpm\fi{}0.06 MeV. We discuss the implications of these measurements for models of isospin mass differences and model-dependent estimates of ${\mathit{f}}_{\mathit{D}}$.

Abstract: We have made measurements of several {ital D}{sub {ital s}} branching ratios, relative to the {phi}{pi}{sup +} mode. We have observed two previously unseen two-body hadronic decays of the {ital D}{sub {ital s}}{sup +}, namely {eta}{rho}{sup +} and {eta}{prime}{rho}{sup +}, and measured relative branching ratios of 2.86{plus minus}0.38{sub {minus}0.38}{sup +0.36} and 3.44{plus minus}0.62{sub {minus}0.46}{sup +0.44}, respectively. We have determined the relative branching ratio for the decay into {phi}{rho}{sup +} to be 1.86{plus minus}0.26{sub {minus}0.40}{sup +0.29}. In addition, we have measured relative branching ratios for the {eta}{pi}{sup +} and {eta}{prime}{pi}{sup +} states, for which there had previously been conflicting measurements; our results are 0.54{plus minus}0.09{plus minus}0.06 and 1.20{plus minus}0.15{plus minus}0.11, respectively. Combining these new measurements with previous results and using (3.7{plus minus}1.2)% for the value of {ital scrB}({ital D}{sub {ital s}}{r arrow}{phi}{pi}{sup +}), we can account for {approx}(79{plus minus}26)% of all {ital D}{sub {ital s}}{sup +} decays. In addition we have also measured relative branching ratios or set upper limits on {ital D}{sup +} decays to all of the above-mentioned final states.

Abstract: Using the CsI calorimeter of the CLEO II detector, the spin triplet {chi}{sub {ital b}}(2{ital P}) states are observed in {Upsilon}(3{ital S}) radiative decays with much higher statistics than seen in previous experiments. The observed mass splittings are not described well by theoretical models, while the relative branching ratios agree with predictions that include relativistic corrections to the radiative transition rates.

Abstract: The spin alignment of ${D}^{*+}$ mesons produced in ${e}^{+}{e}^{\ensuremath{-}}$ annihilation at $\sqrt{s}=10.5$ GeV is obtained from a study of the angular distribution of the decay ${D}^{*+}\ensuremath{\rightarrow}{D}^{0}{\ensuremath{\pi}}^{+}$.

Abstract: We report new measurements of the branching fractions {ital B}({ital B}{sup {minus}}{r arrow}{ital D}{sup 0}{ital l{minus}}{bar {nu}}), {ital B}({ital {bar B}}{sup 0}{r arrow}{ital D}{sup +}{ital l{minus}}{bar {nu}}), and {ital B}({ital B}{sup {minus}}{r arrow}{ital D}{sup *0}{ital l{minus}}{bar {nu}}). Combining these results with our previous measurement of {ital B}({ital {bar B}}{sup 0}{r arrow}{ital D}{sup *+}{ital l{minus}}{bar {nu}}), we find that the ratio of semileptonic widths for final states with a vector meson and pseudoscalar meson is (2.6{sub {minus}0.6{minus}0.8}{sup +1.1+1.0}) and the ratio of charged- to neutral-{ital B}-meson lifetimes is (0.89{plus minus}0.19{plus minus}0.13)({ital f}{sub 00}/{ital f}{sub +{minus}}) where ({ital f}{sub 00}/{ital f}{sub +{minus}}) is the ratio of neutral- to charged-{ital B}-meson production at the {Upsilon}(4{ital S}). From the {ital {bar B}}{r arrow}{ital Dl}{sup {minus}}{bar {nu}} branching fraction, we calculate {vert bar}{ital V}{sub {ital c}{ital b}}{vert bar}=0.040{plus minus}0.006 {plus minus}0.006, where the first error is statistical and the second is systematic and dominated by the uncertainty in the {ital B}-meson lifetime.

Abstract: We report on a study of charged and neutral K ∗ production in tau decay. We obtain a branching ratio value BR (τ − → K ∗- ν τ X 0 ) = (1.43±0.11±0.13)% where X 0 designates possible unobserved neutral particles (charge conjugate modes are implicit). We observe the first signals for inclusive K ∗0 and K ∗0 production in τ − decay, and determine the inclusive branching ratios τ − →K ∗0 K − ν τ X 0 and τ − K ∗0 π − ν τ X 0 to be (0.32±0.08±0.12)% and (0.38±0.11±0.13)%, respectively. We have searched for the decay τ − → K 0 K − ν τ X 0 and set a limit of 8 × 10 −3 at 90% confidence level.

Abstract: A search for lepton flavor violating decays of the tau into either three charged leptons or one charged lepton and two charged hadrons was performed using 2.05 fb[sup [minus]1] of data collected by the CLEO-II experiment at the Cornell Electron Storage Ring. The upper limits obtained for 22 decay branching fractions are several times more stringent than those set previously.

Abstract: Using the CLEO II detector at the Cornell Electron Storage Ring we have measured the $\Xi_c^{0}$ decay asymmetry parameter in the decay $\Xi_c^{0} \to \Xi^{-} \pi^+$. We find $\alpha_{\Xi_c^{0}} \alpha_{\Xi} = 0.26 \pm 0.18{(stat)}^{+0.05}_{-0.04}{(syst)}$, using the world average value of $\alpha_{\Xi} = -0.456 \pm 0.014$ we obtain $\alpha_{\Xi_c^{0}} = -0.56 \pm 0.39{(stat)}^{+0.10}_{-0.09}{(syst)}$. The physically allowed range of a decay asymmetry parameter is $-1

Abstract: We have used the CLEO-II detector at the Cornell Electron Storage Ringe (CESR) to study the inclusive production of charmonium mesons in a sample of 2.15 million {ital B{bar B}} events. We find inclusive branching fractions of (1.12{plus_minus}0.04{plus_minus}0.06)% for {ital B}{r_arrow}{ital J}/{psi}{ital X}, (0.34{plus_minus}0.04{plus_minus}0.03)% for {ital B}{r_arrow}{psi}{prime}{ital X}, and (0.40{plus_minus}0.06{plus_minus}0.04)% for {ital B}{r_arrow}{chi}{sub {ital c}1}{ital X}. We also find some evidence for the inclusive production of {chi}{sub {ital c}2}, and set an upper limit for the branching fraction of the inclusive decay {ital B}{r_arrow}{eta}{sub {ital c}}{ital X} of 0.9% at 90% confidence level. Momentum spectra for inclusive {ital J}/{psi}, {psi}{prime}, and {chi}{sub {ital c}1} production are presented. These measurements are compared to theoretical calculations.
