Abstract: The intake of health foods with physiological effects may cause adverse effects due to their intrinsic compounds, external contamination or consumers` eating patterns. To keep pace with the increasing interest on the safety assurance, Health Functional Food Act has been enacted and standards and specifications for 32 products have been proclaimed by Korea Food and Drug Administration in 2004. To reduce the safety problems related with the intake of non regulated health intended food, we classified the health intended foods materials into two groups, as proclaimed health functional food materials and others, and examined the difference of intake patterns on both categories. Among 16,474 health intended foods responded by 5,175 respondents and their household members, 49.2% were categorized as health functional food materials. The average number of total health intended foods intake and health functional foods intake per person were 3.19 and 1.58 respectively. The proportion of health functional foods in total health intended foods per person was higher in the group with less than 20 years old, therefore this age group needs relatively low concern. On the other hand, 40-59 years old females who have taken the highest number of health food items, 30-59 years old males who had the lowest proportion of health functional foods to total health intended food, and their consumed foods such as medicinal plant and animal protein based restoratives need relatively high concern about intake safety of health foods.

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

Abstract: We have searched for the decays $B\ensuremath{\rightarrow}\ensuremath{\mu}{\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}}\ensuremath{\gamma}$ and $B\ensuremath{\rightarrow}e{\overline{\ensuremath{\nu}}}_{e}\ensuremath{\gamma}$ in a sample of $2.7\ifmmode\times\else\texttimes\fi{}{10}^{6}$ charged $B$ decays collected with the CLEO II detector. In the muon channel, we observe no candidates in the signal region and set an upper limit on the branching fraction of $\mathcal{B}(B\ensuremath{\rightarrow}\ensuremath{\mu}{\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}}\ensuremath{\gamma})l5.2\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$ at the 90% confidence level. In the electron channel, we observe five candidates in the signal region and set an upper limit on the branching fraction of $\mathcal{B}(B\ensuremath{\rightarrow}e{\overline{\ensuremath{\nu}}}_{e}\ensuremath{\gamma})l2.0\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$ at the 90% confidence level.

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: The CLEO II detector is used to search for the production of ${\mathrm{\ensuremath{\chi}}}_{\mathit{c}2}$ states in two-photon interactions.

Using 1.49 ${\mathrm{fb}}^{\mathrm{\ensuremath{-}}1}$ of data taken with beam energies near 5.29 GeV, the two-photon width of the ${\mathrm{\ensuremath{\chi}}}_{\mathit{c}2}$ is determined to be \ensuremath{\Gamma}(${\mathrm{\ensuremath{\chi}}}_{\mathit{c}2}$\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma})=1.08\ifmmode\pm\else\textpm\fi{}0.30(stat)\ifmmode\pm\else\textpm\fi{}0.26(syst) keV, in agreement with predictions from perturbative QCD.

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: 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: 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 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.

Abstract: We report results from a search for the decays ${\mathit{B}}^{0}$\ensuremath{\rightarrow}${\mathrm{\ensuremath{\pi}}}^{+}$${\mathrm{\ensuremath{\pi}}}^{\mathrm{\ensuremath{-}}}$, ${\mathit{B}}^{0}$\ensuremath{\rightarrow}${\mathit{K}}^{+}$${\mathrm{\ensuremath{\pi}}}^{\mathrm{\ensuremath{-}}}$, and ${\mathit{B}}^{0}$\ensuremath{\rightarrow}${\mathit{K}}^{+}$${\mathit{K}}^{\mathrm{\ensuremath{-}}}$. 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: 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]].

Abstract: We have measured branching ratios for three [Lambda][sub [ital c]] decay modes that have a [Sigma][sup +] in the final state. Two of the observed decay modes, [Lambda][sub [ital c]][r arrow][Sigma][sup +][pi][sup 0] and [Lambda][sub [ital c]][sup +][r arrow][Sigma][sup +][omega], have no external [ital W]-emission amplitudes. Their branching ratios relative to the [ital pK][sup [minus]][pi][sup +] mode are 0.20[plus minus]0.03[plus minus]0.03 and 0.54[plus minus]0.13[plus minus]0.06, respectively. We have also significantly improved the measurement of the branching ratio for the previously observed decay mode [Lambda][sub [ital c]][sup +][r arrow][Sigma][sup +][pi][sup +][pi][sup [minus]]. We find its branching ratio relative to [ital pK][sup [minus]][pi][sup +] to be 0.74[plus minus]0.07[plus minus]0.09.

We find branching ratios, relative to ${\mathrm{\ensuremath{\Lambda}}}_{\mathit{c}}^{+}$\ensuremath{\rightarrow}${\mathit{pK}}^{\mathrm{\ensuremath{-}}}$${\mathrm{\ensuremath{\pi}}}^{+}$, of 0.070\ifmmode\pm\else\textpm\fi{}0.011\ifmmode\pm\else\textpm\fi{}0.011 for ${\mathrm{\ensuremath{\Lambda}}}_{\mathit{c}}^{+}$\ensuremath{\rightarrow}${\mathrm{\ensuremath{\Sigma}}}^{+}$${\mathit{K}}^{+}$${\mathit{K}}^{\mathrm{\ensuremath{-}}}$, 0.069\ifmmode\pm\else\textpm\fi{}0.023\ifmmode\pm\else\textpm\fi{}0.016 for ${\mathrm{\ensuremath{\Lambda}}}_{\mathit{c}}^{+}$\ensuremath{\rightarrow}\ensuremath{\Sigma}\ensuremath{\varphi}, 0.078\ifmmode\pm\else\textpm\fi{}0.013\ifmmode\pm\else\textpm\fi{}0.013 for ${\mathrm{\ensuremath{\Lambda}}}_{\mathit{c}}^{+}$\ensuremath{\rightarrow}${\mathrm{\ensuremath{\Xi}}}^{0}$${\mathit{K}}^{+}$, and 0.053\ifmmode\pm\else\textpm\fi{}0.016\ifmmode\pm\else\textpm\fi{}0.010 for ${\mathrm{\ensuremath{\Lambda}}}_{\mathit{c}}^{+}$\ensuremath{\rightarrow}${\mathrm{\ensuremath{\Xi}}}^{\mathrm{*}0}$${\mathit{K}}^{+}$. These measurements indicate that W-exchange diagrams contribute to ${\mathrm{\ensuremath{\Lambda}}}_{\mathit{c}}^{+}$ decay. We have also made a new measurement of the previously found mode ${\mathrm{\ensuremath{\Lambda}}}_{\mathit{c}}^{+}$\ensuremath{\rightarrow}${\mathrm{\ensuremath{\Xi}}}^{\mathrm{\ensuremath{-}}}$${\mathit{K}}^{+}$${\mathrm{\ensuremath{\pi}}}^{+}$.

Abstract: Using data from CLEO II at the Cornell Electron Storage Ring we provide a new measurement of the branching fraction for [ital D][sup 0][r arrow][pi][sup +][pi][sup [minus]], and we present the first measurements of [ital D][sup 0][r arrow][pi][sup 0][pi][sup 0] and of [ital D][sup +][r arrow][pi][sup +][pi][sup 0], which is due to an isospin changing [Delta][ital I]=3/2 transition. From these data we extract the ratio of isospin amplitudes [vert bar][ital A][sub 2]/[ital A][sub 0][vert bar], and the cosine of the relative phase [delta]=[delta][sub 2][minus][delta][sub 0] between these amplitudes, for [ital D][r arrow][pi][pi] decays. Unlike the situation in kaon decay where [ital A][sub 2] is strongly suppressed, we find [vert bar][ital A][sub 2]/[ital A][sub 0][vert bar]=0.72[plus minus]0.13[plus minus]0.11 and cos[delta]=0.14[plus minus]0.13[plus minus]0.09.

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: A limit on the tau neutrino mass [ital M][sub [nu][tau]] is obtained from a study of tau decays in the reaction [ital e][sup +][ital e[minus]][r arrow][tau][sup +][tau][sup [minus]] at center-of-mass energies [similar to]10.6 GeV. The result is based on an end-point analysis of the invariant mass spectrum of the decay products in the decay modes [tau][sup [minus]][r arrow]3[ital h][sup [minus]]2[ital h][sup +][nu][sub [tau]] and [tau][sup [minus]][r arrow]2[ital h][sup [minus]][ital h+]2[pi][sup 0][nu][sub [tau]]. The data sample used in this analysis contains 1.77[times]10[sup 6] tau pairs, corresponding to an integrated luminosity of 1.92 fb[sup [minus]1], and is substantially larger than previous data samples used to place a limit on [ital M][sub [nu][tau]]. The limit obtained for both five-hadron modes together is 32.6 MeV at 95% C.L.

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: We present a measurement of the lepton decay asymmetry ${\mathit{A}}_{\mathrm{fb}}$ in the reaction B\ifmmode\bar\else\textasciimacron\fi{}\ensuremath{\rightarrow}${\mathit{D}}^{\mathrm{*}}$${\mathit{l}}^{\mathrm{\ensuremath{-}}}$\ensuremath{\nu}${\mathrm{\ifmmode\bar\else\textasciimacron\fi{}}}_{\mathit{l}}$ using data collected with the CLEO II detector at the Cornell Electron Storage Ring (CESR). The value of ${\mathit{A}}_{\mathrm{fb}}$ confirms that the chirality of the weak interaction is predominantly left-handed in b\ensuremath{\rightarrow}c transitions as expected in the standard model, if it is assumed that the lepton current is also left-handed. Using ${\mathit{A}}_{\mathrm{fb}}$ and the previously determined branching ratio, ${\mathit{q}}^{2}$ distribution, and ${\mathit{D}}^{\mathrm{*}}$ polarization, we obtain the first measurement of the form-factor ratios that are used to describe this semileptonic decay.

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 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: 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: 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.

Abstract: Using the CLEO-II detector, we have obtained evidence for a new meson decaying to $D^0 K^+$. Its mass is $2573.2^{+1.7}_{-1.6}\pm 0.8\pm 0.5$ {}~MeV/$c^2$ and its width is $16^{+5}_{-4}\pm 3$~MeV/$c^2$. Although we do not establish its spin and parity, the new meson is consistent with predictions for an $L=1$, $S=1$, $J_P=2^+$ charmed strange state., 9 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: Using data from the CLEO II detector at CESR, we measure the [tau]-lepton mass by exploiting the unique kinematics of events in which both [tau]'s decay hadronically. The result is [ital m][sub [tau]]=1777.8[plus minus]0.7[plus minus]1.7 MeV/[ital c][sup 2]. By comparing our result with other measurements near [tau]-pair threshold, we extract an upper limit on the [tau]-neutrino mass of 75 MeV/[ital c][sup 2] at 95% confidence level.
