Abstract

A search for the decay of the meson B±→H±X0 and B0→Ks0X0 was performed. The upper limits for the branching fractions constrained new physics leading to two-body B decays involving any massless neutral feebly interacting particle X0. The first lower bound on the family symmetry breaking scale involving the third generation of quarks at 108 GeV was obtained by applying the limit to the case where X0 was a familon.

Abstract

The first and second moments of the hadronic mass-squared distribution in the B meson semileptonic decay to charm, B → X c ℓ ν, were measured. The measurement of and the heavy quark effective theory expression for this moment were used, in conjunction with similar information on the first moment of the photon energy spectrum in B → s λ. As a result, λ and ∧̄ were determined.

Abstract

The flavor-changing neutral current (FCNC) decay was studied using Monte Carlo simulations to determine the efficiency for detecting the signal modes. The upper limits on branching fractions were obtained and no indication of a signal were obtained for the decay. Systematic and statistical errors for the process were calculated numerically.

Abstract

We have measured the branching fraction and photon energy spectrum for the radiative penguin process b-->s gamma. We find Beta(b-->s gamma) = (3.21+/-0.43+/-0.27(+0.18)(-0.10))x10(-4), where the errors are statistical, systematic, and from theory corrections. We obtain first and second moments of the photon energy spectrum above 2.0 GeV, = 2.346+/-0.032+/-0.011 GeV, and -(2) = 0.0226+/-0.0066+/-0.0020 GeV(2), where the errors are statistical and systematic. From the first moment, we obtain (in the modified minimal subtraction renormalization scheme, to order 1/M(3)(B) and beta(0)alpha(2)(s)) the heavy quark effective theory parameter Lambda = 0.35+/-0.08+/-0.10 GeV.

Abstract

Using 13.6 fb-1 of continuum two-jet e+e-→cc̄ events collected with the CLEO detector, we have searched for baryon number correlations at the primary quark level. We have measured the likelihood for a Λc+ charmed baryon to be produced in the hemisphere opposite a Λc-relative to the likelihood for a Λc+ charmed baryon to be produced opposite an anticharmed meson D̄ in all cases, the reconstructed hadrons must have momentum greater than 2.3 GeV/c. We find that, given a Λc- (reconstructed in five different decay modes), a Λc+ is observed in the opposite hemisphere (0.72±0.11)% of the time (not corrected for efficiency). By contrast, given a D̄ in one hemisphere, a Λc+ is observed in the opposite hemisphere only ±(0.21 0.02)% of the time. Normalized to the total number of either Λc- or D̄ "tags," it is therefore 3.52±0.45±0.42 times more likely to find a Λc+ opposite a Λc- than a D̄ meson. This enhancement is not observed in the JETSET 7.3 e+e-→cc̄Monte Carlo simulation.

Abstract

Using 13.7 fb(-1) of data recorded by the CLEO detector at the Cornell Electron Storage Ring, we investigate the spectrum of charmed baryons which decay into Lambda+(c)pi(-)pi(+) and are more massive than the Lambda+(c)(2625) baryon. We find evidence for two new states: one is broad and has an invariant mass roughly 480 MeV above that of the Lambda+(c) baryon; the other is narrow with an invariant mass of 596+/-1+/-2 MeV above the Lambda+(c) mass.

Abstract

Using data recorded with the CLEO II and CLEO II.V detector configurations at the Cornell Electron Storage Rings, we report the first observation and mass measurement of the Sigma(*+)(c) charmed baryon, and an updated measurement of the mass of the Sigma(+)(c) baryon. We find M(Sigma(*+)(c))-M(Lambda(+)(c)) = (231.0+/-1.1+/-2.0) MeV, and M(Sigma(+)(c))-M(Lambda(+)(c)) = (166.4+/-0.2+/-0.3) MeV, where the errors are statistical and systematic, respectively.

Abstract

Using a sample of 9.6 × 106BB̄ meson pairs collected with the CLEO detector, we have fully reconstructed 135 B0→ψ(′)KS0 and 526 B+→ψ(′)K+ candidates with very low background. We fitted the ψ(′)K invariant mass distributions of these B meson candidates and measured the masses of the neutral and charged B mesons to be M(B0)=5279.1±0.7[stat]±0.3[ syst] MeV/c2 and M(B+)=5279.1±0.4[stat]±0.4[ syst] MeV/c2. The precision is a significant improvement over previous measurements. ©2000 The American Physical Society.

Abstract

We report results of a search for the rare radiative decay B̄0 → D0γ. Using 9.66 × 10 6 BB̄ meson pairs collected with the CLEO detector at the Cornell Electron Storage Ring, we set an upper limit on the branching ratio for this decay of 5.0× 10-5 at 90% C.L. This provides evidence that the anomalous enhancement is absent in W-exchange processes and that weak, radiative B decays are dominated by the short-distance b → sγ mechanism in the standard model. © 2000 The American Physical Society.

Abstract

We have used the CLEO II detector to study the multiplicity of charged particles in the decays of B mesons produced at the Y(4S) resonance. Using a sample of 1.5×106 B meson pairs, we find the mean inclusive charged particle multiplicity to be 10.71±0.02-0.15+0.21 for the decay of the pair. This corresponds to a mean multiplicity of 5.36±0.01-0.08+0.11 for a single B meson. Using the same data sample, we have also extracted the mean multiplicities in semileptonic and nonleptonic decays. We measure a mean of 7.82±0.05-0.19+0.21 charged particles per BB̄ decay when both mesons decay semileptonically. When neither B meson decays semileptonically, we measure a mean charged particle multiplicity of 11.62±0.04-0.18+0.24 per BB̄ pair. ©2000 The American Physical Society.

Abstract

Using a data sample with an integrated luminosity of 3.9 fb collected in e e annihilation with the CLEO-II detector at the Cornell Electron Storage Ring, we have measured the branching ratios for the decay modes D → (η,η′)π and D →(η,η′)ρ relative to D → φπ . These decay modes are among the most common hadronic decays of the D , and can be related by factorization to the semileptonic decays D →(η,η′)ℓ ν . The results obtained are compared with previous CLEO results and with the branching ratios measured for the related semileptonic decays. We also report results on the Cabibbo-suppressed decays of the D to the same final states.

Abstract

Using a data sample with an integrated luminosity of 3.9 fb-1 collected in e+e annihilation with the CLEO-II detector at the Cornell Electron Storage Ring, we have measured the branching ratios for the decay modes D+s → (η,η′)π+ and D+s →(η,η′)ρ+ relative to D+s → φπ+. These decay modes are among the most common hadronic decays of the D+s, and can be related by factorization to the semileptonic decays D+s →(η,η′)ℓ+νl. The results obtained are compared with previous CLEO results and with the branching ratios measured for the related semileptonic decays. We also report results on the Cabibbo-suppressed decays of the D+ to the same final states.

Abstract

A measurement of the spin alignment of charged D* mesons produced in continuum e+e-→cc̄ events at √s = 10.5 GeV is presented. This study using 4.72 fb-1 of CLEO II data shows that there is little evidence of any D* spin alignment.

Abstract

We have studied two-body charmless hadronic decays of B mesons into the final states $\pi\pi$, $K \pi$, and $KK$. Using 3.3 million $B\bar{B}$ pairs collected with the CLEO-II detector, we have made the first observation of the decays $B^0\to K^+\pi^-$, $B^+\to K^0\pi^+$, and the sum of $B^+ \to \pi^+\pi^0$ and $B^+ \to K^+\pi^0$ decays (an average over charge-conjugate states is always implied). We place upper limits on branching fractions for the remaining decay modes., Comment: 9 page postscript file, postscript file also available through http://w4.lns.cornell.edu/public/CLNS

Abstract

Using the CLEO II detector we have performed the first search for $CP$ violation in tau lepton decay. CP violation in lepton decay does not occur in the minimal standard model but can occur in extensions such as the multi-Higgs doublet model. It appears as a characteristic difference between the $\tau^+$ and $\tau^-$ decay angular distributions for the semi-leptonic decay modes such as $\tau^- \to K^0 \pi^- \nu$. We define an observable asymmetry to exploit this and find no evidence for any CP violation., Comment: 9 pages, 4 Postscript figures, postscript file also available through http://w4.lns.cornell.edu/public/CLNS
