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

Abstract: We 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 collected on the $\ensuremath{\Upsilon}(4S)$ resonance and the nearby continuum by the CLEO-II detector, we have studied combinations of baryons with leptons produced in the process $\ensuremath{\Upsilon}(4S)\ensuremath{\rightarrow}B\overline{B}$, $B\ensuremath{\rightarrow}\mathrm{lepton}+X$, $\overline{B}\ensuremath{\rightarrow}\mathrm{baryon}+X$. Our results do not support models which attribute the bulk of ${\ensuremath{\Lambda}}_{c}$ production in $\overline{B}$ decay to the process $b\ensuremath{\rightarrow}{\mathrm{cW}}^{\ensuremath{-}}{,W}^{\ensuremath{-}}\ensuremath{\rightarrow}\overline{c}s$.

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 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: 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: We report the observation of the Cabibbo-suppressed decays {Lambda}{sub {ital c}}{sup +}{r_arrow}{ital pK{sup {minus}}K{sup +}} and {Lambda}{sub {ital c}}{sup +}{r_arrow}{ital p}{phi} using data collected with the CLEO II detector at CESR. 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 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: 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: 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: 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. This result is larger than most theoretical predictions.

Abstract: Using the CLEO II detector, we have measured the branching fractions for [Upsilon](3[ital S])[r arrow][pi][pi][Upsilon](1[ital S]), [Upsilon](3[ital S])[r arrow][pi][pi][Upsilon](2[ital S]), and the cascade [Upsilon](3[ital S])[r arrow][Upsilon](2[ital S])+[ital X], [Upsilon](2[ital S])[r arrow][pi][sup +][pi][sup [minus]][Upsilon](1[ital S]), analyzing the exclusive mode where the daughter [Upsilon] state decays to a [ital e][sup +][ital e[minus]] or [mu][sup +][mu][sup [minus]] pair, as well as the inclusive [pi][sup +][pi][sup [minus]] transitions where the final [Upsilon] state decays into hadrons. Properties of the [pi][pi] system are analyzed. Searches for the cascade decay [Upsilon](3[ital S])[r arrow][pi][sup +][pi][sup [minus]][ital h][sub [ital b]], [ital h][sub [ital b]][r arrow][gamma][eta][sub [ital b]] and [Upsilon](3[ital S])[r arrow][pi][sup 0][ital h][sub [ital b]] were also performed.

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: 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
