Abstract

Using the CLEO detector at the Cornell Electron Storage Ring, we have studied the distribution of kinematic variables in the decay Lambda_c^+ -> Lambda e^+ nu_e. By performing a four-dimensional maximum likelihood fit, we determine the form factor ratio, R = f_2/f_1 = -0.31 +/- 0.05(stat) +/- 0.04(syst), the pole mass, M_{pole} = (2.21 +/- 0.08(stat) +/- 0.14(syst)) GeV/c^2, and the decay asymmetry parameter of the Lambda_c, alpha_{Lambda_c} = -0.86 +/- 0.03(stat) +/- 0.02(syst), for = 0.67 (GeV/c^2)^2. We compare the angular distributions of the Lambda_c^+ and Lambda_c^- and find no evidence for CP-violation: A_{Lambda_c} = (alpha_{Lambda_c^+} + alpha_{Lambda_c^-})/ (alpha_{Lambda_c^+} - alpha_{Lambda_c^-}) = 0.00 +/- 0.03(stat) +/- 0.01(syst) +/- 0.02, where the third error is from the uncertainty in the world average of the CP-violating parameter, A_{Lambda}, for Lambda -> p pi^-., Comment: 8 pages postscript,also available through http://www.lns.cornell.edu/public/CLNS/2004/, submitted to PRL

Abstract

Using 4.68 fb^{-1} of e^+e^- annihilation data collected with the CLEO II detector at the Cornell Electron Storage Ring (CESR) we have studied tau radiative decays tau -> mu nu nu gamma and tau -> e nu nu gamma. For a 10 MeV minimum photon energy in the tau rest frame, the branching fraction of radiative tau decay to a muon or electron is measured to be (3.61+-0.16+-0.35)*10^{-3} or (1.75+-0.06+-0.17)*10^{-2}, respectively. The branching fractions are in agreement with the Standard Model theoretical predictions., 11 pages postscript, also available through http://w4.lns.cornell.edu/public/CLNS

Abstract

Using the CLEO detector at the Cornell Electron Storage Ring, we have studied the distribution of kinematic variables in the decay Lambda(c)(+)->Lambda e(+)nu(e). By performing a four-dimensional maximum likelihood fit, we determine the form factor ratio, R=f(2)/f(1)=-0.31 +/- 0.05(stat)+/- 0.04(syst), the pole mass, M-pole=[2.21 +/- 0.08(stat)+/- 0.14(syst)] GeV/c(2), and the decay asymmetry parameter of the Lambda(c)(+), alpha(Lambda c)=-0.86 +/- 0.03(stat)+/- 0.02(syst), for < q(2)>=0.67 (GeV/c(2))(2). We compare the angular distributions of the Lambda(c)(+) and (Lambda) over bar (-)(c) and find no evidence for CP violation: A(Lambda c)=(alpha(Lambda c)+alpha((Lambda) over barc))/(alpha(Lambda c)-alpha((Lambda) over barc))=0.00 +/- 0.03(stat)+/- 0.01(syst)+/- 0.02, where the third error is from the uncertainty in the world average of the CP-violating parameter, A(Lambda), for Lambda -> p pi(-).

Abstract

We report on a search for CP violation in the decay of D-0 and D-0 to K(S)(0)pi(+)pi(-). The data come from an integrated luminosity of 9.0 fb(-1) of e(+)e(-) collisions at rootsapproximate to10 GeV recorded with the CLEO II.V detector. The resonance substructure of this decay is well described by ten quasi-two-body decay channels plus a small nonresonant component. We observe no evidence for CP violation in the amplitudes that describe the decay D-0-->K(S)(0)pi(+)pi(-).

Abstract

We report on a search for a CP-violating asymmetry in the charmless hadronic decay B-->K*(892)(+/-)pi(-/+), using 9.1 fb(-1) of integrated luminosity produced at roots = 10.58 GeV and collected with the CLEO detector. We find A(CP)(B-->K*(892)(+/-)pi(-/+)) = 0.26(-0.34)(+0.33)(stat)(-0.08)(+0.10)(syst), giving an allowed interval of [-0.31,0.78] at the 90% confidence level.

Abstract

We report on determinations of \V-ub\ resulting from studies of the branching fraction and q(2) distributions in exclusive semileptonic B decays that proceed via the b-->u transition. Our data set consists of the 9.7x106B (B) over bar meson pairs collected at the Y(4S) resonance with the CLEO II detector. We measure B(B-0-->pi(-)l(+)nu)=(1.33+/-0.18+/-0.11+/-0.01+/-0.07)x10(-4) and B(B-0-->rho(-)l(+)nu)=(2.17+/-0.34(-0.54)(+0.47)+/-0.41+/-0.01)x10(-4), where the errors are statistical, experimental systematic, systematic due to residual form-factor uncertainties in the signal, and systematic due to residual form-factor uncertainties in the cross-feed modes, respectively. We also find B(B+-->etal(+)nu)=(0.84+/-0.31+/-0.16+/-0.09)x10(-4), consistent with what is expected from the B-->pilnu mode and quark model symmetries. We extract \V-ub\ using light-cone sum rules for 0less than or equal toq(2)

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.

The search for such a state was motivated by the recent discovery by the BaBar Collaboration of a narrow state at 2.32 GeV/c(2), the D-sJ*(2317)(+), that decays to D(s)(+)pi(0). Reconstructing the D(s)(+)pi(0) and D-s*(+)pi(0) final states in CLEO data, we observe peaks in both of the corresponding reconstructed mass difference distributions, DeltaM(D(s)pi(0))=M(D(s)pi(0))-M(D-s) and DeltaM(D-s*pi(0))=M(D-s*pi(0))-M(D-s*), both of them at values near 350 MeV/c(2). We interpret these peaks as signatures of two distinct states, the D-sJ*(2317)(+) plus a new state, designated as the D-sJ(2463)(+). Because of the similar DeltaM values, each of these states represents a source of background for the other if photons are lost, ignored or added. A quantitative accounting of these reflections confirms that both states exist. We have measured the mean mass differences =350.0+/-1.2 (stat)+/-1.0 (syst) MeV/c(2) for the D-sJ*(2317)(+) state, and =351.2+/-1.7 (stat)+/-1.0 (syst) MeV/c(2) for the new D-sJ(2463)(+) state. We have also searched, but find no evidence, for decays of the two states via the channels D-s*(+)gamma, D(s)(+)gamma, and D(s)(+)pi(+)pi(-). The observations of the two states at 2.32 and 2.46 GeV/c(2), in the D(s)(+)pi(0) and D-s*(+)pi(0) decay channels, respectively, are consistent with their interpretations as c (s) over bar mesons with an orbital angular momentum L=1 and spin and parity J(P)=0(+) and 1(+).

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.

Abstract

We have searched for the baryon-containing radiative penguin decays B- -->Lambda(p) over bar gamma and B--->Sigma(0)(p) over bar gamma, using a sample of 9.7x10(6) B (B) over bar events collected at the Y(4S) with the CLEO detector. We find no evidence for either, and set 90% confidence level upper limits of B(B--->Lambda(p) over bar gamma)+0.3B(B--->Sigma(0)(p) over bar gamma)](Egamma)>2.0 GeVSigma(0)(p) over bar gamma)+0.4B(B--->Lambda(p) over bar gamma)](Egamma)>2.0 GeVX(s)gamma,X-s containing baryons)(Egamma)>2.0 GeVsgamma that are less than half the combined statistical and systematic errors quoted on these quantities.

Abstract

In the brain and heart, rapidly inactivating (A-type) voltage-gated potassium (Kv) currents operate at subthreshold membrane potentials to control the excitability of neurons and cardiac myocytes. Although pore-forming alpha-subunits of the Kv4, or Shal-related, channel family form A-type currents in heterologous cells, these differ significantly from native A-type currents. Here we describe three Kv channel-interacting proteins (KChIPs) that bind to the cytoplasmic amino termini of Kv4 alpha-subunits. We find that expression of KChIP and Kv4 together reconstitutes several features of native A-type currents by modulating the density, inactivation kinetics and rate of recovery from inactivation of Kv4 channels in heterologous cells. All three KChIPs co-localize and co-immunoprecipitate with brain Kv4 alpha-subunits, and are thus integral components of native Kv4 channel complexes. The KChIPs have four EF-hand-like domains and bind calcium ions. As the activity and density of neuronal A-type currents tightly control responses to excitatory synaptic inputs, these KChIPs may regulate A-type currents, and hence neuronal excitability, in response to changes in intracellular calcium.
