Abstract

We describe the design, construction and performance of a Ring Imaging Cherenkov Detector (RICH) constructed to identify charged particles in the CLEO experiment. Cherenkov radiation occurs in LiF crystals, both planar and ones with a novel ``sawtooth''-shaped exit surface. Photons in the wavelength interval 135--165 nm are detected using multi-wire chambers filled with a mixture of methane gas and triethylamine vapor. Excellent pion/kaon separation is demonstrated., Comment: 75 pages, 57 figures, (updated July 26, 2005 to reflect reviewers comments), to be published in NIM A

Author

Cronin-Hennessey, D, Kwon, Y, Lyon, A, Thorndike, E, Jessop, C, Mariske, H, Perl, M, Savinov, V, Ugolini, D, Zhou, X, Coan, T, Fadeyez, V, Maravin, Y, Narsky, I, Stroynowski, R, Ye, J, Wlodek, T, Artuso, M, Ayad, R, Boulahouache, C, Bukin, K, Dambasuren, E, Karamnov, S, Kopp, S, and Majumder, G

Abstract

We have studied charmless hadronic decays of B mesons into two-body final states with kaons and pions and observe three new processes with the following branching fractions: beta(B-->pi(+)pi(-)) = (4.3(+1. 6)(-1.4)+/-0.5)x10(-6), beta(B-->K(0)pi(0)) = (14.6(+5.9+2.4)(-5.1-3. 3))x10(-6), and beta(B-->K(+)/-pi(0)) = (11.6(+3.0+1.4)(-2.7-1.3))x10(-6). We also update our previous measurements for the decays B-->K(+)/-pi(-/+) and B+/--->K(0)pi(+/-).

Abstract

We have studied the color-suppressed hadronic decays of neutral B mesons into the final states D*0pi(0). Using 9.67 x 10(6) BB pairs collected with the CLEO detector, we observe the decays B( 0) --> D0pi(0) and B( 0) -->D(*0)pi(0) with the branching fractions BB( 0) -->D0pi(0)) = (2.74(+0.36)(-0.32) +/- 0.55)x10(-4) and BB( 0) -->D(*0)pi(0)) = (2.20(+0.59)(-0.52) +/- 0.79)x10(-4). The first error is statistical and the second systematic. The statistical significance of the D0pi(0) signal is 12.1sigma ( 5.9sigma for D(*0)pi(0)). Utilizing the B( 0) -->D*0)pi(0) branching fractions we determine the strong phases delta(I,D(*)) between isospin 1/2 and 3/2 amplitudes in the Dpi and D*pi final states to be cosdelta(I,D) = 0.89 +/-0.08 and cosdelta(I,D*) = 0.89 +/- 0.08, respectively.

8. Evidence for the decay D0 → Κ+π-π+π

Author

Abstract

We present a search for the "wrong-sign" decay D0 → Κ+π-π+π- using 9 fb-1 of e+e- collisions on and just below the Y(4S) resonance. This decay can occur either through a doubly Cabibbo-suppressed process or through mixing to a D̄0 followed by a Cabibbo-favored process. Our result for the time-integrated wrong-sign rate relative to the decay D0 → Κ-π+π-π+ is (0.0041-0.0011+0.0012(stat)±0.0004(syst))×(1.07 ±0.10)(phase space), which has a statistical significance of 3.9 standard deviations. ©2001 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

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

The CLEO experiment at the CESR collider has used 13.7 fb(-1) of data to search for the production of the Omega(0)(c) (css ground state) in e(+)e(-) collisions at square root of (s) approximately 10.6 GeV. The modes used to study the Omega(0)(c) are Omega(-)pi(+), Omega(-)pi(+)pi(0), Xi-K-pi(+)pi(+), Xi0K-pi(+), and Omega(-)pi(+)pi(+)pi(-). We observe a signal of 40.4+/-9.0(stat) events at a mass of 2694.6+/-2.6(stat)+/-1.9(syst) MeV/c(2), for all modes combined.

Abstract

We have measured the CP asymmetry A(CP) identical with[gamma(b-->sgamma)-gammab-->sgamma)]/[gamma(b-->sgamma)+gamma(b-->sgamma)] to be A(CP) = (-0.079+/-0.108+/-0.022) (1.0+/-0.030), implying that, at 90% confidence level, A(CP) lies between -0.27 and +0.10. These limits rule out some extreme non-standard-model predictions, but are consistent with most, as well as with the standard model.

Abstract

In the standard model, the charged current of the weak interaction is governed by a unitary quark mixing matrix that also leads to CP violation. Measurement of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements is essential to searches for new physics, either through the structure of the CKM matrix, or a departure from unitarity. We determine the CKM matrix element |Vcb| using a sample of 3 × 106 BB̄ events in the CLEO detector at the ornell Electron Storage Ring. We determine the yield of reconstructed B̄0 →D*+ℓv̄ and B-→D*0ℓv̄ decays as a function of w, the boost of the D* in the B rest frame, and from this we obtain the differential decay rate dΓ/dw. By extrapolating dΓ/dw to w = 1, the kinematic end point at which the D* is at rest relative to the B, we extract the product |Vcb|F(1), where F(1) is the form factor at w = 1. We find |Vcb|F(1) = 0.0431±0.0013(stat) ±0.0018(syst). We combine |Vcb|F(1) with theoretical results for F(1) to determine |Vcb| = 0.0469±0.0014(stat)±0.0020)syst)±0.0018(theor). We also integrate the differential decay rate over w to obtain B(B̄0→D*+ℓv̄) = (6.09±0.19±0.40)% and B(B-→D*0ℓv̄) = (6.50±0.20±0.43)%.

Abstract

We present final measurements of 13 charmless hadronic B decay modes from the CLEO experiment. The decay modes include the ten pipi, Kpi, and KK final states and new limits on dibaryonic final states, p (p) over bar, p (&ULambda;) over bar, and Lambda(&ULambda;) over bar, as well as a new determination of the ratio B(B-->DK)/B(B-->Dpi). The results are based on the full CLEO II and CLEO III data samples totalling 15.3 fb(-1) at the Y(4S), and supercede previously published results.

Abstract

Using 13.8 fb(-1) of data collected at or just below the Y(4S) with the CLEO detector, we report the result of a search for the flavor changing neutral current process D-0 --> gammagamma. We observe no significant signal for this decay mode and determine 90% confidence level upper limits on the branching fractions B(D-0 --> gammagamma)/B(D-0 --> pi(0)pi(0)) < 0.033 and B(D-0 --> gammagamma) < 2.9 x 10(-5).

Abstract

Using the CLEO II detector at CESR, we measure the eta' energy spectra in Y(1S) decays that we compare with models of the eta'g*g form factor. This form factor, especially at large eta' energies, may provide an explanation of the large rate for B-->X(s)eta'. Our data do not support a large anomalous coupling at higher q(2) and thus the large eta' rate remains a mystery, possibly requiring a non-standard-model explanation.

Abstract

In the standard model, the charged current of the weak interaction is governed by a unitary quark mixing matrix that also leads to CP violation. Measurement of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements is essential to searches for new physics, either through the structure of the CKM matrix, or a departure from unitarity. We determine the CKM matrix element \V-cb\ using a sample of 3x10(6) B (B) over bar events in the CLEO detector at the Cornell Electron Storage Ring. We determine the yield of reconstructed (B) over bar (0)-->D*(+)l (ν) over bar and B--->D(*0)l (ν) over bar decays as a function of w, the boost of the D* in the B rest frame, and from this we obtain the differential decay rate dGamma/dw. By extrapolating dGamma/dw to w=1, the kinematic end point at which the D* is at rest relative to the B, we extract the product \V-cb\F(1), where F(1) is the form factor at w=1. We find \V-cb\F(1)=0.0431+/-0.0013(stat)+/-0.0018(syst). We combine \V-cb\F(1) with theoretical results for F(1) to determine \V-cb\=0.0469+/-0.0014(stat)+/-0.0020(syst)+/-0.0018(theor). We also integrate the differential decay rate over w to obtain B((B) over bar (0)-->D*(+)(ν) over bar)=(6.09+/-0.19+/-0.40)% and B(B--->D*(0)l (ν) over bar)=(6.50+/-0.20+/-0.43)%.

Abstract

Using 9.1 fb(-1) of e(+)e(-) data collected at the Y(4S) with the CLEO detector using the Cornell Electron Storage Ring, measurements are reported for both the branching fractions and the helicity amplitudes for the decays B--->D(*0)rho(-) and (B) over bar (0)-->D(*+)rho(-). The fraction of longitudinal polarization in (B) over bar (0)-->D(*+)rho(-) is found to be consistent with that in (B) over bar (0)-->D(*+)l(-)(ν) over bar at q(2)=M-rho(2), indicating that the factorization approximation works well. The longitudinal polarization in the B- mode is similar. The measurements also show evidence of nontrivial final-state interaction phases for the helicity amplitudes.

Abstract

Using data collected by the CLEO III detector at CESR, we report on the first observation of the decays Lambda(c)(+)-->Lambdapi(+)pi(+)pi(-)pi(0) and Lambda(c)(+)-->Lambdaomegapi(+). The branching fractions are measured relative to the pK(-)pi(+) mode; we find B(Lambda(c)(+)-->Lambdapi(+)pi(+)pi(-)pi(0))/B(Lambda(c)(+)-->pK(-)pi(+))=0.36+/-0.09(stat)+/-0.09(syst) and B(Lambda(c)(+)-->Lambdaomegapi(+))/B(Lambda(c)(+)-->pK(-)pi(+))=0.24+/-0.06(stat)+/-0.06(syst). We also observe a small excess of events in Lambda(c)(+)-->Lambdaetapi(+), eta-->pi(+)pi(-)pi(0) from which we find B(Lambda(c)(+)-->Lambdaetapi(+))/B(Lambda(c)(+)-->pK(-)pi(+))=0.41+/-0.17+/-0.10 with a corresponding limit of Lambdaetapi(+), eta-->gammagamma. We find that the combined branching fractions for Lambda(c)(+)-->Lambdaomegapi(+) and Lambda(c)(+)-->Lambdaetapi(+) comprise (87+/-13)% of the total Lambda(c)(+)-->Lambdapi(+)pi(+)pi(-)pi(0) rate. We set an upper limit on B(Lambda(c)(+)-->Lambdapi(+)pi(+)pi(-)pi(0))/B(Lambda(c)(+)-->pK(-)pi(+)) for non-omega and non-eta modes of 0.13 at 90% confidence level.

Abstract

We measure the primary lepton momentum spectrum in (B) over bar -->Xl (ν) over bar decays, for plgreater than or equal to1.5 GeV/c in the B rest frame. From this, we calculate various moments of the spectrum. In particular, we find R(0)equivalent tointegral(1.7 GeV)(dGamma/dE(sl))dEl/integral(1.5 GeV)(dGamma/dE(sl))dEl=0.6187+/-0.0014(stat)+/-0.0016(sys) and R(1)equivalent tointegral(1.5 GeV)El(dGamma/dE(sl))dEl/integral(1.5 GeV)(dGamma/dE(sl))dEl=(1.7810+/-0.0007(stat)+/-0.0009(sys)) GeV. We use these moments to determine non-perturbative parameters governing the semileptonic width. In particular, we extract the heavy quark expansion parameters (&ULambda;) over bar=(0.39+/-0.03(stat)+/-0.06(sys)+/-0.12(th)) GeV and lambda(1)=(-0.25+/-0.02(stat)+/-0.05(sys)+/-0.14(th)) GeV2. The theoretical constraints used are evaluated through order 1/M-B(3) in the non-perturbative expansion and beta(0)alpha(s)(2) in the perturbative expansion. We use these parameters to extract \V-cb\ from the world average of the semileptonic width and find \V-cb\=(40.8+/-0.5(Gammasl)+/-0.4((lambda1),((&ULambda;) over bar )exp)+/-0.9(th))x10(-3). In addition, we extract the short range b-quark mass m(b)(1S)=(4.82+/-0.07(exp)+/-0.11(th)) GeV/c(2). Finally, we discuss the implications of our measurements for the theoretical understanding of inclusive semileptonic processes.

The three-body decay Β→K0π+π- with a branching fraction (50-9+10±7)X10-6 was observed. A simultaneous analysis of the Dalitz plots for this decay and for Β→K+π-π0 revealed the presence of Β→K*+(892)π- with a branching fraction (16-5+6±2)X10-6, which is larger than but consistent with most theoretical predictions.

Abstract

Using data collected by the CLEO detector in the Upsilon(4S) region, we report new measurements of the exclusive decays of B mesons into final states of the type Lambda_c^+ p-bar n(pi), where n=0,1,2,3. We find signals in modes with one, two and three pions and an upper limit for the two body decay Lambda_c^+ pbar. We also make the first measurements of exclusive decays of B mesons to Sigma_c p-bar n(pi), where n=0,1,2. We find signals in modes with one and two pions and an upper limit for the two body decay Sigma_c p-bar. Measurements of these modes shed light on the mechanisms involved in B decays to baryons., Comment: 11 pages postscript, also available through http://w4.lns.cornell.edu/public/CLNS, submitted to PRL

Abstract

The ratios of the branching fractions and the combined branching fraction ratio was measured. The decay rate measured in this work consisted with the lattice gauge calculations and ISGW2 model prediction. The ratio of the vector and pseudoscalar decay widths was consistent with the predictions of quark models.

Abstract

The ratio of charged and neutral B meson production at the γ(4S), f +-/f 00, is measured through the decays B̄→D*ℓ -ν̄ ℓ, reconstructed using a partial reconstruction method where the D* is detected only through a pion daughter from the decay D*→Dπ. Using data collected by the CLEO II detector, the charged and neutral B decays are measured in such a way that their ratio is independent of the decay model, limited mainly by the uncertainty in the relative efficiency for detecting neutral and charged pions. This measurement yields the ratio of production fractions times the ratio of semileptonic branching fractions, f +-b +/f 00b 0. Assuming that b +/b 0 is equal to the lifetime ratio τ +/τ 0 and using the world average value of τ +/τ 0 as input, we obtain f +-/f 00= 1.058±0.084±0.136. © 2002 The American Physical Society.

Abstract

In e(+)e(-) collisions using the CLEO detector, we have studied the decay of the D0 to the final state K(0)(S)pi(+)pi(-) with the initial flavor of the D0 tagged by the decay D(*+)-->D0pi(+). We use the Dalitz technique to measure the resonant substructure in this final state and clearly observe ten different contributions by fitting for their amplitudes and relative phases. We observe a K(*)(892)(+)pi(-) component which arises from doubly Cabibbo suppressed decays or D0-D0; mixing.

Abstract

We report a new measurement of the Cabibbo-Kobayashi-Maskawa parameter Vub made with a sample of 9.7 x 10(6) BB- events collected with the CLEO II detector. Using heavy quark theory, we combine the observed yield of leptons from semileptonic B decay in the end-point momentum interval 2.2-2.6 GeV/c with recent CLEO II data on B-->X(s)gamma to find Vub = (4.08+/-0.34+/-0.44+/-0.16+/-0.24)x10(-3), where the first two uncertainties are experimental and the last two are from theory.

Abstract

We describe several measurements using the decays D0→K+K- and π+π-. We find the ratio of partial widths, Γ(D0→K+K-)/Γ (D0→π+π-), to be 2.96±0.16±0.15, where the first error is statistical and the second is systematic. We observe no evidence for direct CP violation, obtaining ACP(KK)=(0.0±2.2±0.8)% and ACP(ππ)=(1.9±3.2±0.8)%. In the limit of no CP violation we measure the mixing parameter yCP=-0.012±0.025±0.014 by measuring the lifetime difference between D0→K+K- or π+ π- and the CP neutral state, D0→K-π+. We see no evidence for mixing.

Abstract

Continuing our studies of radiative Υ decays, we report on a search for Υ→γη and fj(2220) in 61.3 pb-1 of e+e- data taken with the CLEO II detector at the Cornell Electron Storage Ring. For the γη search the three decays of the η meson to π+ π- π0, π0 π0 π0, and γγ were investigated. We found no candidate events in the (3 π)0 modes and no significant excess over expected backgrounds in the γγ mode to set a limit on the branching fraction of B(Y→γη)< 2.1 × 10-5 at 90% C.L. The three charged two-body final states hh̄(h = π+, K+, p) were investigated for fj(2220) production, with one, one, and two events found, respectively. Limits at 90% C.L. of B(Υ→γfj) × B(fj→hh̄) ∼ 1.5 × 10-5 have been set for each of these modes. We compare our results to measurements of other radiative Υ decays, to measurements of radiative J/ψ decays, and to theoretical predictions.

Abstract

The exclusive decays B̄ → D(*)K*-, using 9.66 × 106 BB̄ pairs collected at the γ(4S) with the CLEO detector was reported. Some branching fractions were measured such as β(B- → D0K*-) = (6.1 ± 1.6 ± 1.7) × 10-4. It was found that the B̄ → D*K*- branching ratios were averages of those corresponding to the 00 and 11 helicity states.
