Abstract: We report on a study of [ital W]+ photon production in approximately 20 pb[sup [minus]1] of [ital p][minus][ital [bar p]] collisions at [radical][ital s]=1.8 TeV recorded with the Collider Detector at Fermilab. Our results are in good agreement with standard model expectations and are used to obtain limits on anomalous [ital CP]-conserving [ital WW][gamma] couplings of [minus]2.3[lt][Delta][kappa][lt]2.2 for [lambda]=0 and [minus]0.7[lt][lambda][lt]0.7 for [Delta][kappa]=0 at 95% C.L. We obtain the same limits for [ital CP]-violating couplings. These results provide limits on the higher-order electromagnetic moments of the [ital W] boson of 0.8[lt][ital g][sub [ital W]][lt]3.1 for [ital q][sup [ital e]][sub [ital W]]=1 and [minus]0.6[lt][ital q][sup [ital e]][sub [ital W]][lt]2.7 for [ital g][sub [ital W]]=2 at 95% C.L.

Abstract: We report an improved measurement of muon anti-neutrino disappearance over a distance of 735km using the MINOS detectors and the Fermilab Main Injector neutrino beam in a muon anti-neutrino enhanced configuration. From a total exposure of 2.95e20 protons on target, of which 42% have not been previously analyzed, we make the most precise measurement of the anti-neutrino "atmospheric" delta-m squared = 2.62 +0.31/-0.28 (stat.) +/- 0.09 (syst.) and constrain the anti-neutrino atmospheric mixing angle >0.75 (90%CL). These values are in agreement with those measured for muon neutrinos, removing the tension reported previously., 5 pages, 4 figures. In submission to Phys.Rev.Lett

Abstract: We report constraints on antineutrino oscillation parameters that were obtained by using the two MINOS detectors to measure the 7% muon antineutrino component of the NuMI neutrino beam. In the Far Detector, we select 130 events in the charged-current muon antineutrino sample, compared to a prediction of 136.4 +/- 11.7(stat) ^{+10.2}_{-8.9}(syst) events under the assumption |dm2bar|=2.32x10^-3 eV^2, snthetabar=1.0. Assuming no oscillations occur at the Near Detector baseline, a fit to the two-flavor oscillation approximation constrains |dm2bar, Accepted for publication by Phys. Rev.

Abstract: Measurements of neutrino oscillations using the disappearance of muon neutrinos from the Fermilab NuMI neutrino beam as observed by the two MINOS detectors are reported. New analysis methods have been applied to an enlarged data sample from an exposure of $7.25 \times 10^{20}$ protons on target. A fit to neutrino oscillations yields values of $|\Delta m^2| = (2.32^{+0.12}_{-0.08})\times10^{-3}$\,eV$^2$ for the atmospheric mass splitting and $\rm \sin^2\!(2\theta) > 0.90$ (90%\,C.L.) for the mixing angle. Pure neutrino decay and quantum decoherence hypotheses are excluded at 7 and 9 standard deviations, respectively., Comment: 5 pages, 4 figures

Abstract: The average b-hadron lifetime has been measured using a high statistics sample of {ital B} {r_arrow} {ital J}/{psi}{Chi} decays recorded with the Collider Detector at Fermilab. We use a sample with an integrated luminosity of {approx} 90 {ital pb}{sup -1} recorded during the 1994-95 running period. The decay vertices of {approx} 62656 inclusive {ital J}/{psi} {r_arrow} {mu}{sup +}{mu}{sup -} candidates have been reconstructed using information from a silicon vertex-detector. The measured {ital B}lifetime, which is the average over all b-hadrons produced in {ital p}{ital {anti p}} collisions at {radical}s = 1.8 TeV weighted by their branching ratios into {ital J}/{psi}, is 1.524 {+-} 0.015 ({ital stat}){sup +0.035}{sub -0.026} ({ital sys}) ps. The precision of this measurement is significantly improved compared to the inclusive lifetime measurement published previously using {approx} 10 {ital pb}{sup -1}.

Abstract: We report measurements of the $D^0, D^+$, and $D^+_s$ meson lifetimes using $3.7 fb^{-1}$ of e^+e^- annihilation data collected near the $\Upsilon(4S)$ resonance with the CLEO detector. The lifetimes of the $D^0, D^+$, and $D^+_s$ mesons are measured to be $408.5 \pm 4.1 ^{+3.5}_{-3.4} fs, 1033.6 \pm 22.1 ^{+9.9}_{-12.7} fs$, and $486.3 \pm 15.0 ^{+4.9}_{-5.1} fs$, respectively. The precisions of the charm meson lifetimes reported here are comparable to those of the best previous measurements, and the systematic errors are very different. In a single experiment we find that the ratio of the $D^+_s$ and $D^0$ lifetimes differs from one by more than 4.5 standard deviations., Comment: 10 pages, postscript file also available through http://w4.lns.cornell.edu/public/CLNS

Abstract: We report a new measurement of dijet production by color-singlet exchange in p{ovr p} collisions at {radical}(s)=1.8 TeV at the Fermilab Tevatron. In a sample of events with two jets of transverse energy E{sup jet}{sub T}{gt}20 GeV , pseudorapidity in the range 1.8{lt}{vert_bar}{eta}{sup jet}{vert_bar}{lt}3.5 , and {eta}{sub 1}{eta}{sub 2}{lt}0 , we find that a fraction R=[1.13{plus_minus}0.12(stat){plus_minus} 0.11(syst)]{percent} has a pseudorapidity gap within {vert_bar}{eta}{vert_bar}{lt}1 between the jets that can be attributed to color-singlet exchnage. The fraction R shows no significant dependence on E{sup jet}{sub T} or on the pseudorapidity separation between the jets. {copyright} {ital 1998} {ital The American Physical Society}

Abstract: We report the observation and measurement of the rate of diffractive dijet production at the Fermilab Tevatron p̄p collider at √s = 1.8 TeV. In events with two jets of ET > 20 GeV, 1.8 0, we find that the diffractive to nondiffractive production ratio is RJJ = [0.75 ± 0.05(stat) ± 0.09(syst)]%. By comparing this result, in combination with our measured rate for diffractive W boson production reported previously, with predictions based on a hard partonic pomeron structure, we determine the pomeron gluon fraction to be fg = 0.7 ± 0.2. 79 14 2636 2641 Cited By :78

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: We report the first observation of diffractively produced W bosons. In a sample of W{r_arrow}e{nu} events produced in p{bar p} collisions at {radical}(s)=1.8TeV, we find an excess of events with a forward rapidity gap, which is attributed to diffraction. The probability that this excess is consistent with nondiffractive production is 1.1{times}10{sup -4} (3.8{sigma}). The relatively low fraction of W+jet events observed within this excess implies that mainly quarks from the Pomeron, which mediates diffraction, participate in W production. The diffractive to nondiffractive W production ratio is found to be R{sub W}=(1.15{plus_minus}0.55){percent}. {copyright} {ital 1997} {ital The American Physical Society}

Abstract: We present a measurement of the forward-backward charge asymmetry of the process p p̄ → Z0/γ + X, Z0/γr → e+ e- at Mee > Mz, using 110 pb-1 of data at √s = 1.8 TeV collected at the Collider Detector at Fermilab. The measured charge asymmetries are 0.43 ± 0.10 in the invariant mass region Mee > 105 GeV/c2, and 0.070 ± 0.016 in the region 75 < Mee < 105 GeV/c2. These results are consistent with the standard model values of 0.528 ± 0.009 and 0.052 ± 0.002, respectively. 77 13 2616 2621 Cited By :22

Abstract: We present the result of a search for charged Higgs boson decays of the top quark, produced in $p\overline{p}$ collisions at $\sqrt{s}=1.8$ TeV. When the charged Higgs boson is heavy and decays to a $\ensuremath{\tau}$ lepton, which subsequently decays hadronically, the resulting events have a unique signature: large missing transverse energy and the low-charged-multiplicity $\ensuremath{\tau}$. Data collected in 1992 and 1993 at the Collider Detector at Fermilab, corresponding to 18.7\ifmmode\pm\else\textpm\fi{}0.7 ${\mathrm{pb}}^{\ensuremath{-}1}$, exclude new regions of combined top quark and charged Higgs boson mass, in extensions to the standard model with two Higgs doublets.

Abstract: We report on a search for supersymmetry using dilepton events which complements the classic missing ET plus multijet analyses. Using 19 pb-1 of p̄p collisions at √s = 1.8 TeV recorded with the Collider Detector at Fermilab we have searched for squarks and gluinos decaying into charginos and producing events with two leptons. We observe one candidate event. In comparison, the expected number of background events from standard model processes is 2.39 ± 0.63(stat)-0.42 +0.77(syst). Hence we set limits on gluino and squark production based on predictions from the supergravity inspired minimal supersymmetric extension of the standard model. 76 12 2006 2010 Cited By :42

Abstract: The properties of high-mass multijet events produced at the Fermilab proton-antiproton collider are compared with leading order QCD matrix element predictions, QCD parton shower Monte Carlo predictions, and the predictions from a model in which events are distributed uniformly over the available multibody phase-space. Multijet distributions corresponding to (4N-4) variables that span the N-body parameter space are found to be well described by the QCD calculations for inclusive three-jet, four-jet, and five-jet events. The agreement between data, QCD Matrix Element calculations, and QCD parton shower Monte Carlo predictions suggests that 2 -> 2 scattering plus gluon radiation provides a good first approximation to the full LO QCD matrix element for events with three, four, or even five jets in the final state., 49 pages with 19 figures.

Abstract: We present a study of W+multijet events that compares the kinematics of the observed events with expectations from direct QCD W+jet production and from production and decay of top quark pairs. The data were collected in the 1992--93 run with the Collider Detector at Fermilab (CDF) from 19.3 ${\mathrm{pb}}^{\mathrm{\ensuremath{-}}1}$ of proton-antiproton collisions at \ensuremath{\surd}s =1.8 TeV. A W+\ensuremath{\ge}2 jet sample and a W+\ensuremath{\ge}3 jet sample are selected with the requirement that at least the two or three jets have energy transverse with respect to the beam axis in excess of 20 GeV. The jet energy distributions for the W+\ensuremath{\ge}2 jet sample agree well with the predictions of direct QCD W production. From the W+\ensuremath{\ge}3 jet events, a ``signal sample'' with an improved ratio of tt\ifmmode\bar\else\textasciimacron\fi{} to QCD produced W events is selected by requiring each jet to be emitted centrally in the event center of mass frame. This sample contains 14 events with unusually hard jet ${\mathit{E}}_{\mathit{T}}$ distributions not well described by expectations for jets from direct QCD W production and other background processes. Using expected jet ${\mathit{E}}_{\mathit{T}}$ distributions, a relative likelihood is defined and used to determine if an event is more consistent with the decay of tt\ifmmode\bar\else\textasciimacron\fi{} pairs, with ${\mathit{M}}_{\mathrm{top}}$=170 GeV/${\mathit{c}}^{2}$, than with direct QCD W production. Eight of the 14 signal sample events are found to be more consistent with top-quark than direct QCD W production, while only 1.7 such top-quark--like events are expected in the absence of tt\ifmmode\bar\else\textasciimacron\fi{}.The probability that the observation is due to an upward fluctuation of the number of background events is found to be 0.8%. The robustness of the result was tested by varying the cuts defining the signal sample, and the largest probability for such a fluctuation found was 1.9%. Good agreement in the jet spectra is obtained if jet production from tt\ifmmode\bar\else\textasciimacron\fi{} pair decays is included. For those events kinematically more consistent with tt\ifmmode\bar\else\textasciimacron\fi{} we find evidence for a b-quark content in their jets to the extent expected from top quark decay, and larger than expected for background processes. For events with four or more jets, the discrepancy with the predicted jet distributions from direct QCD W production, and the associated excess of b-quark content, is more pronounced.

Abstract: The properties of two-, three-, four-, five-, and six-jet events with multijet masses >600 GeV /c2 are compared with QCD predictions. The shapes of the multijet-mass and leading-jet-angular distributions are approximately independent of jet multiplicity and are well described by the NJETS matrix element calculation and the HERWIG parton shower Monte Carlo predictions. The observed jet transverse momentum distributions for three- and four-jet events discriminate between the matrix element and parton shower predictions, the data favoring the matrix element calculation. © 1995 The American Physical Society. 75 4 608 612 Cited By :25

Abstract: We present a direct measurement of the width of the W boson using the shape of the transverse mass distribution of W->enu candidates selected in 1 fb-1 of data collected with the D0 detector at the Fermilab Tevatron collider in ppbar collisions at sqrt{s}=1.96 TeV. We use the same methods and data sample that were used for our recently published W boson mass measurement, except for the modeling of the recoil, which is done with a new method based on a recoil library. Our result, 2.028 +- 0.072 GeV, is in agreement with the predictions of the standard model., 7 pages, 1 figure, published in Phys. Rev. Lett

Abstract: We have used a kinematic technique to distinguish top quark pair production from background in pp\ifmmode\bar\else\textasciimacron\fi{} collisions at \ensuremath{\surd}s=1.8 TeV, applied to 67 ${\mathrm{pb}}^{\mathrm{\ensuremath{-}}1}$ of data. We define a sample of W+\ensuremath{\ge}3 jet events in which the jets are produced at large angles relative to the incident beams. In this sample, we find an excess of events with large jet transverse energies relative to expectations from background. The excess is consistent with top quark production; a large fraction of events in this kinematic region contains b jets. We interpret these results as evidence that most of the selected events are from tt\ifmmode\bar\else\textasciimacron\fi{} decay.

Abstract: We report limits on anomalous [ital ZZ][gamma] and [ital Z][gamma][gamma] couplings derived from an analysis of [ital Z]+photon production based upon approximately 20pb[sup [minus]1] of the [bar p] collision data recorded by the Collider Detector at Fermilab. We observe good agreement with the standard model expectation that all [ital Z][gamma] couplings are zero. Confidence level intervals for individual couplings and contours for pairs of [ital CP]-conserving/violating [ital ZZ][gamma] and [ital Z][gamma][gamma] couplings are presented.

Abstract: We present the results of a search for the top quark in 19.3 pb[sup [minus]1] of [ital [bar p]p] collisions at [radical][ital s] =1.8 TeV. The data were collected at the Fermilab Tevatron collider using the Collider Detector at Fermilab (CDF). The search includes standard model [ital t[bar t]] decays to final states [ital ee][nu][bar [nu]], [ital e][mu][nu][bar [nu]], and [mu][mu][nu][bar [nu]] as well as [ital e]+[nu]+jets or [mu]+[nu]+jets. In the ([ital e],[mu])+[nu]+jets channel we search for [ital b] quarks from [ital t] decays via secondary vertex identification and via semileptonic decays of the [ital b] and cascade [ital c] quarks. In the dilepton final states we find two events with a background of 0.56[sub [minus]0.13][sup +0.25] events. In the [ital e],[mu]+[nu]+jets channel with a [ital b] identified via a secondary vertex, we find six events with a background of 2.3[plus minus]0.3. With a [ital b] identified via a semileptonic decay, we find seven events with a background of 3.1[plus minus]0.3. The secondary vertex and semileptonic-decay samples have three events in common. The probability that the observed yield is consistent with the background is estimated to be 0.26%. The statistics are too limited to firmly establish the existence of the more » top quark; however, a natural interpretation of the excess is that it is due to [ital t[bar t]] production. We present several cross-checks. Some support this hypothesis; others do not. Under the assumption that the excess yield over background is due to [ital t[bar t]], constrained fitting on a subset of the events yields a mass of 174[plus minus]10[sub [minus]12][sup +13] GeV/[ital c][sup 2] for the top quark. The [ital t[bar t]] cross section, using this top quark mass to compute the acceptance, is measured to be 13.9[sub [minus]4.8][sup +6.1] pb. « less

Abstract: A prompt photon cross section measurement from the Collider Detector at Fermilab experiment is presented. Detector and trigger upgrades, as well as 6 times the integrated luminosity compared with our previous publication, have contributed to a much more precise measurement and extended PT range. As before, QCD calculations agree qualitatively with the measured cross section, but the data has a steeper slope than the calculations. © 1994 The American Physical Society. 73 20 2662 2666 Cited By :105

Abstract: The lifetime of the $B_s$ meson is measured using the semileptonic decay $B_s \to D_s^- \ell^+ \nu X$. The data sample consists of 19.3 pb$^{-1}$ of $p \bar{p}$ collisions at $\sqrt{s} = 1.8$ TeV collected by the CDF detector at the Fermilab Tevatron collider during 1992-1993. There are $76 \pm 8$ $\ell^{+} D_s^{-}$ signal events where the $D_s$ is identified via the decay $D_s^{-} \to \phi \pi^{-}$,~$\phi \to K^+ K^-$. Using these events, the $B_s$ meson lifetime is determined to be $\tau_{s} = 1.42^{+ 0.27}_{- 0.23} {\rm (stat)} \pm 0.11 {\rm (syst)}$ ps. A measurement of the $B_s$ lifetime in a low statistics sample of exclusive $B_s \to J/\psi \phi$ decays is also presented in this paper., Comment: 18 pages, 3 figures (2 .ps 1 .eps)

Abstract: If quarks are composite particles then excited states are expected. We have searched in pp\ifmmode\bar\else\textasciimacron\fi{} collisions for excited quarks (${\mathit{q}}^{\mathrm{*}}$) which decay to common quarks by emitting a W boson (${\mathit{q}}^{\mathrm{*}}$\ensuremath{\rightarrow}qW) or a photon (${\mathit{q}}^{\mathrm{*}}$\ensuremath{\rightarrow}q\ensuremath{\gamma}). The simplest model of excited quarks has been excluded for mass ${\mathit{M}}^{\mathrm{*}}$540 GeV/${\mathit{c}}^{2}$ at 95% confidence level.

Abstract: The dijet invariant mass distribution has been measured in the region between 140 and 1000 GeV/${\mathit{c}}^{2}$, in 1.8 TeV p p\ifmmode\bar\else\textasciimacron\fi{} collisions. Data collected with the Collider Detector at Fermilab show agreement with QCD calculations. A limit on quark compositeness of ${\mathrm{\ensuremath{\Lambda}}}_{\mathit{c}}$g1.3 TeV is obtained. Axigluons with masses between 240 and 640 GeV/${\mathit{c}}^{2}$ are excluded at 95% C.L. if we assume ten open decay channels. Model-independent limits on the production of heavy particles decaying into two jets are also presented.

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

Abstract: This Letter describes a direct search for charged Higgs boson production in proton-antiproton collisions at sqrt(s)=1.8 TeV recorded by the Collider Detector at Fermilab. Two-Higgs-doublet extensions to the standard model predict the existence of charged Higgs bosons. In such models, the branching fraction for top quarks B(t --> H b --> tau nu b) can be large.

Abstract: We have measured the branching fractions for B -> D_bar X, B -> D X, and B -> D_bar X \ell^+ ��, where ``B'' is an average over B^0 and B^+, ``D'' is a sum over D^0 and D^+, and``D_bar'' is a sum over D^0_bar and D^-. From these results and some previously measured branching fractions, we obtain Br(b -> c c_bar s) = (21.9 $\pm$ 3.7)%, Br(b -> s g) < 6.8% @ 90% c.l, and Br(D^0 -> K^- ��^+) = (3.69 $\pm$ 0.20)%. Implications for the ``B semileptonic decay problem'' (measured branching fraction being below theoretical expectations) are discussed. The increase in the value of Br(b -> c c_bar s) due to $B -> D X$ eliminates 40% of the discrepancy., 12 page postscript file, postscript file also available through http://w4.lns.cornell.edu/public/CLNS

Abstract: We describe the properties of six-jet events, with the six-jet mass exceeding 520GeV/c{sup 2}, produced at the Fermilab proton-antiproton collider operating at a center-of-mass energy of 1.8 TeV. Observed distributions for a set of 20 multijet variables are compared with predictions from the HERWIG QCD parton shower Monte Carlo program, the NJETS leading order QCD matrix element Monte Carlo program, and a phase-space model in which six-jet events are distributed uniformly over the kinematically allowed region of the six-body phase space. In general the QCD predictions provide a good description of the observed six-jet distributions. {copyright} {ital 1997} {ital The American Physical Society}
