Abstract

The first measurement of the true top quark PT distributon was carried out. An attempt was also made to compute a 95% confidence level upper limit on the fraction of top quarks that are produced with 225 > PT > 425 GeV/c. It was found that R4 > 0.16 at 95% C.L.

Abstract

We have studied the production of B hadrons in 1.8-TeV pp[over ¯] collisions. We present measurements of the fragmentation fractions, f_{u}, f_{d}, f_{s}, and f_{baryon}, of produced b quarks that yield B^{+}, B^{0}, B_{s}^{0}, and Λ[over ¯]_{b}^{0} hadrons. Reconstruction of five electron-charm final states yields f_{s}/( f_{u}+f_{d})=0.213±0.068 and f_{baryon}/( f_{u}+f_{d})=0.118±0.042, assuming f_{u}=f_{d}. If all B hadrons produced in pp[over ¯] collisions cascade to one of these four hadrons, we determine f_{u}=f_{d}=0.375±0.023, f_{s}=0.160±0.044, and f_{baryon}=0.090±0.029. If we do not assume f_{u}=f_{d}, we find f_{d}/f_{u}=0.84±0.16.

5. Jet pseudorapidity distribution in direct photon events in p(p)over-bar collisions at root s=1.8 TeV

Abstract

We present the first measurement of the jet pseudorapidity distribution in direct photon events from a sample of pp̄ collisions at √s= 1.8 TeV, recorded with the Collider Detector at Fermilab. Quantum chromodynamics (QCD) predicts that these events are primarily from hard quark-gluon Compton scattering, qg→qγ, with the final state quark producing the jet of hadrons. The jet pseudorapidity distribution in this model is sensitive to parton momentum fractions between 0.015 and 0.15. We find that the shape of the measured pseudorapidity distribution agrees well with next-to-leading order QCD calculations.

Abstract

Neutron Higgs bosons produced in association with `b' quarks were investigated. Experimental results showed that there was no evidence for the existence of such a signal. The data was interpreted using the Neutral Higgs sector of the supersymmetric extension of standard model. The lower mass limits for neutral Higgs bosons were derived for tanβ values in excess of 35.

Abstract

Events collected by the Collider Detector at Fermilab (CDF) with an energetic jet plus large missing transverse energy can be used to search for physics beyond the standard model. We see no deviations from the expected backgrounds and set upper limits on the production of new processes. We consider in addition the production of light gravitinos and set a limit at 95% confidence level on the breaking scale √F ≥ 217 GeV, which excludes gravitino masses smaller than 1.1 × 10-5 eV/c2. © 2000 The American Physical Society.

Abstract

We have measured the polarization of J/ψ and ψ(2S) mesons produced in pp̄ collisions at √s = 1.8 TeV, using data collected at the Collider Detector at Fermilab during 1992-1995. The polarization of promptly produced J/ψ [ψ(2S)] mesons is isolated from those produced in B-hadron decay, and measured over the kinematic range 4 [5.5] < PT < 20 GeV/c and |y| < 0.6. For PT ≳ 12 GeV/c we do not observe significant polarization in the prompt component. © 2000 The American Physical Society.

Abstract

We search for new particles that decay into bb̄ and are produced with W bosons in pp̄ collisions at √s = 1.8 TeV. The search uses 109 ± 7 pb-1 accumulated by the CDF experiment at Fermilab. We select events with an ev or μv, and two jets, one of them b tagged. The number of events and the two-jet mass distribution are consistent with expectations. Using W + Higgs production as a model for the acceptance, we set an upper limit on the production cross section times branching ratio for the new particle ranging from 14 to 19 pb (95% C.L.) as the particle mass varies from 70 to 120 GeV/c2.

Abstract

We report the results of a search for a W' boson produced in pp collisions at a center-of-mass energy of 1.8 TeV using a 107 pb-1 data sample recorded by the Collider Detector at Fermilab. We consider the decay channel W'-->andmunumu and search for anomalous production of high transverse mass munumu lepton pairs. We observe no excess of events above background and set limits on the rate of W' boson production and decay relative to standard model W boson production and decay using a fit of the transverse mass distribution observed. If we assume standard model strength couplings of the W' boson to quark and lepton pairs, we exclude a W' boson with invariant mass less than 660 GeV/c2 at 95% confidence level.

Abstract

We present the first measurement of the ratio of branching fractions R identical withB(t-->Wb)/B(t-->Wq) from p_p collisions at sqrt[s] = 1.8 TeV. The data set corresponds to 109 pb(-1) of data recorded by the Collider Detector at Fermilab during the 1992-95 Tevatron run. We measure R = 0.94(+0.31)(-0.24)(stat+syst) or R>0.61 (0.56) at 90% (95)% C.L., in agreement with the standard model predictions. This measurement yields a limit on the Cabibbo-Kobayashi-Maskawa quark mixing matrix element /V(tb)/ under the assumption of three generations and unitarity.

Abstract

We present a measurement of the B0 ↔ B̄0 oscillalion frequency using a flavor tagging method based on correlations of B meson flavor with the charge of other particles produced in pp̄ collisions at √s = 1.8 TeV. Such correlations are expected to arise from b quark hudronization and from B** decays. We partially reconstruct B mesons using the semileptonic decays B0 → D(*)-X and B+ rarr; -D̄0X. From the oscillation frequency, we obtain the mass difference between the two B0 mass eigenstates. Δmd = 0.471 -0.068+0.078(stat) ± 0.034(syst)ℏ ps-1, and measure the efficiency and purity of this flavor tagging method for both charged and neutral B mesons.

Abstract

We present the first general measurements (invariant-mass, transverse-energy, and angular distributions) of the process, p̄p→γ+2 jets+X, using data collected by the CDF at Fermilab. We compare the data with predictions from a tree-level QCD calculation and the PYTHIA shower Monte Carlo program. Our data sample is particularly sensitive to contributions from initial- and final-state radiation of photons and jets. Using the PYTHIA Monte Carlo program, we contrast the kinematical distributions for direct photon production with those for initial- and final-state photon radiation (bremsstrahlung). Based on the angular distributions, we find that our data favor a mixture of bremsstrahlung and direct photon production, as predicted, over either process alone.

Abstract

We present a measurement of the W boson mass using data collected with the CDF detector during the 1994-1995 collider run at the Fermilab Tevatron. A fit to the transverse mass spectrum of a sample of 30115 W → ev events recorded in an integrated luminosity of 84 pb-1 gives a mass MW=80.473±0.065(stat) ±0.092(syst) GeV/c2. A fit to the transverse mass spectrum of a sample of 14740 W → μν events from 80 pb-1 gives a mass MW=80.465±0.100(stat)±0.103(syst) GeV/c2. The dominant contributions to the systematic uncertainties are the uncertainties in the electron energy scale and the muon momentum scale, 0.075 GeV/c2 and 0.085 GeV/c2, respectively. The combined value for the electron and muon channel is MW=80.470±0.089 GeV/c2. When combined with previously published CDF measurements, we obtain MW=80.433±0.079GeV/c2. ©2001 The American Physical Society.

Abstract

We report a measurement of the ratios of the decay rates of the B+, B0, and Bs 0 mesons into exclusive final states containing a J/ψ meson. The final states were selected from 19.6 pb-1 of pp̄ collisions recorded by the Collider Detector at Fermilab. These data are interpreted to determine the b quark fragmentation fractions fu, fd, and fs. We also determine the branching fractions for the decay modes B+ → J/ψK+, B+ → J/ψK*(892)+, B0 → J/ψK0, B0 → J/ψK*(892)0, and Bs 0 → J/ψφ(1020). We discuss the implications of these measurements to B meson decay models. © 1996 The American Physical Society.

We find no evidence of such a signal and the data are interpreted in the context of the neutral Higgs sector of the minimal supersymmetric extension of the standard model. With basic parameter choices for the supersymmetric scale and the stop-quark mixing, we derive 95% C.L. lower mass limits for neutral Higgs bosons for tan(beta) values in excess of 35.

The photon from their decay into J/psi(gamma) is reconstructed through conversion into e+e- pairs. The energy resolution this technique provides makes the resolution of the two states possible. We find the ratio of production cross sections sigma(chi(c2))/sigma(chi(c1)) = 0.96+/-0.27(stat)+/-0.11(syst) for events with pT(J/psi) > 4.0 GeV/c, /eta(J/psi)/ < 0.6, and pT(gamma) > 1.0 GeV/c.

The jet energy calibration and the method used to extract the inclusive jet cross section are described. We discuss the main uncertainties, which are dominated by the jet energy scale uncertainty. The results cover jet transverse momenta from 50GeV to 600GeV with jet rapidities in the range -2.4 to 2.4 and are compared to predictions using recent proton parton distribution functions. Studies of correlations between systematic uncertainties in transverse momentum and rapidity are presented. © 2012 American Physical Society.

Abstract

The collider detector at Fermilab was used to examine second and third generation leptoquarks. The potential production of color triplet technipions in strongly-coupled color octet technirhos decays was examined. Events with heavy flavor jets and missing energy may indicate the second-generation leptoquark decay to a charm quark and neutrino. Since there were no excess of events above standard model predictions, 95% confidence level limits were determined.
