Abstract

We searched for radio pulsars in 25 of the non-variable, unassociated sources in the Fermi LAT Bright Source List with the Green Bank Telescope at 820 MHz. We report the discovery of three radio and gamma-ray millisecond pulsars (MSPs) from a high Galactic latitude subset of these sources. All of the pulsars are in binary systems, which would have made them virtually impossible to detect in blind gamma-ray pulsation searches. They seem to be relatively normal, nearby (<=2 kpc) millisecond pulsars. These observations, in combination with the Fermi detection of gamma-rays from other known radio MSPs, imply that most, if not all, radio MSPs are efficient gamma-ray producers. The gamma-ray spectra of the pulsars are power-law in nature with exponential cutoffs at a few GeV, as has been found with most other pulsars. The MSPs have all been detected as X-ray point sources. Their soft X-ray luminosities of ~10^{30-31} erg/s are typical of the rare radio MSPs seen in X-rays., Comment: Accepted for publication in ApJ Letters

Abstract

We present precise phase-connected pulse timing solutions for 16 gamma-ray-selected pulsars recently discovered using the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope plus one very faint radio pulsar (PSR J1124-5916) that is more effectively timed with the LAT. We describe the analysis techniques including a maximum likelihood method for determining pulse times of arrival from unbinned photon data. A major result of this work is improved position determinations, which are crucial for multi-wavelength follow up. For most of the pulsars, we overlay the timing localizations on X-ray images from Swift and describe the status of X-ray counterpart associations. We report glitches measured in PSRs J0007+7303, J1124-5916, and J1813-1246. We analyze a new 20 ks Chandra ACIS observation of PSR J0633+0632 that reveals an arcminute-scale X-ray nebula extending to the south of the pulsar. We were also able to precisely localize the X-ray point source counterpart to the pulsar and find a spectrum that can be described by an absorbed blackbody or neutron star atmosphere with a hard powerlaw component. Another Chandra ACIS image of PSR J1732-3131 reveals a faint X-ray point source at a location consistent with the timing position of the pulsar. Finally, we present a compilation of new and archival searches for radio pulsations from each of the gamma-ray-selected pulsars as well as a new Parkes radio observation of PSR J1124-5916 to establish the gamma-ray to radio phase offset., Comment: 59 pages, 57 figures, accepted by ApJS

Abstract

We report the discovery of eight gamma-ray pulsars in blind frequency searches using the LAT, onboard the Fermi Gamma-ray Space Telescope. Five of the eight pulsars are young (tau_c<100 kyr), energetic (Edot>10^36 erg/s), and located within the Galactic plane (|b|<3 deg). The remaining three are older, less energetic, and located off the plane. Five pulsars are associated with sources included in the LAT bright gamma-ray source list, but only one, PSR J1413-6205, is clearly associated with an EGRET source. PSR J1023-5746 has the smallest characteristic age (tau_c=4.6 kyr) and is the most energetic (Edot=1.1E37 erg/s) of all gamma-ray pulsars discovered so far in blind searches. PSRs J1957+5033 and J2055+25 have the largest characteristic ages (tau_c~1 Myr) and are the least energetic (Edot~5E33 erg/s) of the newly-discovered pulsars. We present the timing models, light curves, and detailed spectral parameters of the new pulsars. We used recent XMM observations to identify the counterpart of PSR J2055+25 as XMMU J205549.4+253959. In addition, publicly available archival Chandra X-ray data allowed us to identify the likely counterpart of PSR J1023-5746 as a faint, highly absorbed source, CXOU J102302.8-574606. The large X-ray absorption indicates that this could be among the most distant gamma-ray pulsars detected so far. PSR J1023-5746 is positionally coincident with the TeV source HESS J1023-575, located near the young stellar cluster Westerlund 2, while PSR J1954+2836 is coincident with a 4.3 sigma excess reported by Milagro at a median energy of 35 TeV. Deep radio follow-up observations of the eight pulsars resulted in no detections of pulsations and upper limits comparable to the faintest known radio pulsars, indicating that these can be included among the growing population of radio-quiet pulsars in our Galaxy being uncovered by the LAT, and currently numbering more than 20., Comment: Submitted to ApJ

Abstract

Using the combined CLEO II and CLEO II.V data sets of 9.1 fb(-1) at the Upsilon(4S), we measure properties of psi mesons produced directly from decays of the B meson, where "B" denotes an admixture of B+, B-, B0, and B;(0), and "psi" denotes either J/psi(1S) or psi(2S). We report first measurements of psi polarization in B-->psi(direct)X: alpha(psi(1S))=-0.30(+0.07)(-0.06)+/-0.04 and alpha(psi(2S))=-0.45(+0.22)(-0.19)+/-0.04. We also report improved measurements of the momentum distributions of psi produced directly from B decays, correcting for measurement smearing. Finally, we report measurements of the inclusive branching fraction for B-->psiX and B-->chi(c1)X.

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

We report on a study of the invariant mass spectrum of the hadronic system in the decay τ-→π-π0ντ. This study was performed with data obtained with the CLEO II detector operating at the CESR e+e- collider. We present fits to phenomenological models in which resonance parameters associated with the ρ(770) and ρ(1450) mesons are determined. The π-π0 spectral function inferred from the invariant mass spectrum is compared with data on e+e-π+π- as a test of the conserved vector current theorem. We also discuss the implications of our data with regard to estimates of the hadronic contribution to the muon anomalous magnetic moment. ©2000 The American Physical Society.

Abstract

We report on a search for charmless hadronic B decays to the three-body final states K(0)(S)h(+)pi(-), K(+)h(-)pi(0), K(0)(S)h(+)pi(0) (h(+/-) denotes a charged pion or kaon), and their charge conjugates, using 13.5 fb(-1) of integrated luminosity produced near sqrt[s]=10.6 GeV, and collected with the CLEO detector. We observe the decay B-->K0pi(+)pi(-) with a branching fraction (50(+10)(-9)(stat.)+/-7(syst.))x10(-6) and the decay B-->K(*+)(892)pi(-) with a branching fraction (16(+6)(-5)(stat.)+/-2(syst.))x10(-6).

13. Measurement of Β(B - → D 0π -) and Β(B - → D +π -) and isospin analysis of B̄ → Dπ decays

Abstract

We present new measurements of branching fractions for the color-favored decays B + → D 0π - and B̄ 0 → D +π -. Using 9.67×10 6 BB̄ pairs collected with the CLEO detector, we obtain the branching fractions Β(B - → D 0π - = (49.7±1.2±2.9±2.2)×10 4 and Β(B̄ 0 → D +π -) = (26.8±1.2±2.4±1.2)×10 -4. The first error is statistical, the second is systematic, and the third is due to the experimental uncertainty on the production ratio of charged and neutral B mesons in Y(4S) decays. These results, together with the current world average for the color-suppressed branching fraction Β(B̄ + → D 0π 0), are used to determine the cosine of the strong phase difference δ I between the I = 1/2 and I=3/2 isospin amplitudes. We find cos δ I = 0.863 -0.023-0.035-0.030+0.024+0.036+0.038, and obtain a 90% confidence interval of 16.5° < δ I < 38.1°. This nonzero value of δ I suggests the presence of final state interactions in the D π system. © 2002 The American Physical Society.

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

This article describes improved measurements by CLEO of the B0→Ds+D*- and B0→Ds*+D*- branching fractions, and first evidence for the decay B+→Ds(*)+D̄** 0, where D̄**0 represents the sum of the D̄1(2420)0, D̄2*(2460)0, and D̄1(j = 1/2)0 L = 1 charm meson states. Also reported is the first measurement of the Ds*+ polarization in the decay B0→Ds*+D*-. A partial reconstruction technique, employing only the fully reconstructed Ds+ and slow pion πs- from the D*-→D̄0πs- decay, enhances sensitivity. The observed branching fractions are B(B0→Ds+D*-) = (1.10±0.18±0.10±0.28)%, B(B0→Ds*+D*-) = (1.82±0.37±0.24 ±0.46)% , and B(B+→Ds(*) +D̄**0) = (2.73±0.78±0.48±0.68)%, where the first error is statistical, the second systematic, and the third is the uncertainty in the Ds+→φπ+ branching fraction. The measured Ds*+ longitudinal polarization, ΓL/Γ = (50.6±13.9±3.6)%, is consistent with the factorization prediction of 54%.

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 the observation of the eta(c)'(2(1)S(0)), the radial excitation of the eta(c)(1(1)S(0)) ground state of charmonium, in the two-photon fusion reaction gammagamma --> eta(c)' --> (KsK+/-)-K-0 pi(-/+) in 13.6 fb(-1) of CLEO II/ILV data and 13.1 fb(-1) of CLEO III data. We obtain M(eta(c)') = 3642.9 +/- 3.1 (stat) +/- 1.5(syst) MeV and M(eta(c)) = 2981.8 +/- 1.3(stat) +/- 1.5(syst) MeV. The corresponding values of hyperfine splittings between S-1(0) and S-3(1) states are DeltaM(hf)(1S) = 115.1 +/- 2.0 MeV and DeltaM(hf)(2S) = 43.1 +/- 3.4 MeV. Assuming that the eta(c) and eta(c)' have equal branching fractions to K(s)Kpi, we obtain Gamma(gammagamma)(eta(c)') = 1.3 +/- 0.6 keV.

Abstract

We report a new measurement of the B-meson semileptonic decay momentum spectrum that has been made with a sample of 9.4 fb(-1) of e(+)e(-) data collected with the CLEO II detector at the Y(4S) resonance. Electrons from primary semileptonic decays and secondary charm decays were separated by using charge and angular correlations in Y(4S) events with a high-momentum lepton and an additional electron. We determined the semileptonic branching fraction to be B(B-->Xe(+)nu(e))=(10.91+/-0.09+/-0.24)% from the normalization of the electron-energy spectrum. We also measured the moments of the electron-energy spectrum with minimum energies from 0.6 to 1.5 GeV.

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

Using the CLEO detector at the Cornell Electron-positron Storage Ring, we have measured the scaled momentum spectra, dsigma/dx(p), and the inclusive production cross sections of the charm mesons D+, D-0, Dstar+, and D-star0 in e(+)e(-) annihilation at about 10.5 GeV center of mass energy, excluding the decay products of B mesons. The statistical accuracy and momentum resolution are superior to previous measurements at this energy.

Abstract

We present the first study of the vector (Wess-Zumino) current in tau(-)-->K(-)pi(-)K(+)nu(tau) decay using data collected with the CLEO III detector at the Cornell Electron Storage Ring. We determine the quantitative contributions to the decay width from the vector and axial vector currents. Within the framework of a model by Kuhn and Mirkes, we identify the quantitative contributions to the total decay rate from the intermediate states omegapi, rho(('))pi, and (KK)-K-*.

Abstract

Using the CLEO III detector at CESR, we have measured the branching ratio of the decay Xi(c)(0)-->pK(-)K(-)pi(+) relative to Xi(c)(0)-->Xi(-)pi(+). We find B(Xi(c)(0)-->pK(-)K(-)pi(+))B(Xi(c)(0)-->Xi(-)pi(+))=0.35+/-0.06(stat)+/-0.03(syst). In the resonant substructure of this mode, we find evidence for Xi(c)(0) decays to pK(*)(892)K-0(-), and measure B(Xi(c)(0)-->pK(*)(892)K-0(-))xB(K-*(892)(0)-->K(-)pi(+))/B(Xi(c)(0)-->Xi(-)pi(+))=0.14+/-0.03(stat)+/-0.01(syst) and B(Xi(c)(0)-->pK(-)K(-)pi(+))/B(Xi(c)(0)-->Xi(-)pi(+))=0.21+/-0.04(stat)+/-0.02(syst) for the non-K-*(892)(0)Xi(c)(0)-->pK(-)K(-)pi(+) decays.

Abstract

Using a 13.7 fb(-1) data sample collected with the CLEO II and II.V detectors, we report new branching fraction measurements for two Cabibbo-suppressed decay modes of the D+ meson: B(D+-->pi(+)pi(0))=(1.31+/-0.17+/-0.09+/-0.09)x10(-3) and B(D+-->K+(K) over bar (0))=(5.24+/-0.43+/-0.20+/-0.34)x10(-3) which are significant improvements over past measurements. The errors reflect statistical and systematical uncertainties as well as the uncertainty in the absolute D+ branching fraction scale. We also set the first 90% confidence level upper limit on the branching fraction of the doubly Cabibbo-suppressed decay mode B(D+-->K(+)pi(0))

Abstract

We present the first evidence for the production of Y(1D) states in the four-photon cascade, Y(3S)-->gammachi(b)(2P), chi(b)(2P)-->gammaY(1D), Y(1D)-->gammachi(b)(1P), chi(b)(1P)-->gammaY(1S), followed by the Y(1S) annihilation into e(+)e(-) or mu(+)mu(-). The signal has a significance of 10.2 standard deviations. The measured product branching ratio for these five decays, (2.5+/-0.5+/-0.5)x10(-5), is consistent with the theoretical estimates. The data are dominated by the production of one Y(1D) state consistent with the J=2 assignment. Its mass is determined to be (10161.1+/-0.6+/-1.6) MeV, which is consistent with the predictions from potential models and lattice QCD calculations. We also searched for Y(3S)-->gammachi(b)(2P), chi(b)(2P)-->gammaY(1D), followed by either Y(1D)-->etaY(1S) or Y(1D)-->pi(+)pi(-)Y(1S). We find no evidence for such decays and set upper limits on the product branching ratios.

Abstract

We present a measurement of the composition of B meson inclusive semileptonic decays using 9.4 fb(-1) of e(+)e(-) data taken with the CLEO detector at the Y(4S) resonance. In addition to measuring the charged lepton kinematics, the neutrino four-vector is inferred using the hermiticity of the detector. We perform a maximum likelihood fit over the full three-dimensional differential decay distribution for the fractional contributions from the B-->X(c)lnu processes with X-c=D, D-*, D-**, and nonresonant X-c, and the process B-->X(u)lnu. From the fit results we extract the first and second moments of the M-X(2) and q(2) distributions with minimum lepton-energy requirements of 1.0 GeV and 1.5 GeV. We find =(0.456+/-0.014+/-0.045+/-0.109) GeV2/c(4) with a minimum lepton energy of 1.0 GeV and =(0.293+/-0.012+/-0.033+/-0.048) GeV2/c(4) with minimum lepton energy of 1.5 GeV. The uncertainties are from statistics, detector systematic effects, and model dependence, respectively. As a test of the HQET and OPE calculations, the results for the M-X(2) moment as a function of the minimum lepton energy requirement are compared to the predictions.

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 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.

Abstract

Using 13.5 fb(-1) of e(+)e(-) annihilation data collected with the CLEO II detector, we have observed a narrow resonance decaying to D-s*(+)pi(0) with a mass near 2.46 GeV/c(2). 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 data collected on the Y(4S) resonance and the nearby continuum by the CLEO detector at the Cornell Electron Storage Ring, we have searched for the semileptonic decay of B mesons to e (p) over bar inclusive final states. We obtain an upper limit for b-->c decays of B(B-->(p) over bare(-)(ν) over bar X-e)u decay, we find an upper limit of B(B--->p (p) over bare(-)(ν) over bar (e))p (p) over bare(-)(ν) over bar (e))
