Abstract: We present results from a measurement of double diffraction dissociation in $\bar pp$ collisions at the Fermilab Tevatron collider. The production cross section for events with a central pseudorapidity gap of width $\Delta\eta^0>3$ (overlapping $\eta=0$) is found to be $4.43\pm 0.02{(stat)}{\pm 1.18}{(syst) mb}$ [$3.42\pm 0.01{(stat)}{\pm 1.09}{(syst) mb}$] at $\sqrt{s}=1800$ [630] GeV. Our results are compared with previous measurements and with predictions based on Regge theory and factorization., Comment: 10 pages, 4 figures, using RevTeX. Submitted to Physical Review Letters

Abstract: We have measured the number of like-sign (LS) and opposite-sign (OS) lepton pairs arising from double semileptonic decays of b and (b) over bar hadrons, pair produced at the Fermilab Tevatron collider. The data samples were collected with the Collider Detector at Fermilab during the 1992-1995 collider run by triggering on the existence of mumu or emu candidates in an event. The observed ratio of LS to OS dileptons leads to a measurement of the average time-integrated mixing probability of all produced b-flavored hadrons which decay weakly, (χ) over bar =0.152+/-0.007 (stat)+/-0.011 (syst), that is significantly larger than the world average (χ) over bar =0.118+/-0.005.

Abstract: We report results from a study of events with a double Pomeron exchange topology produced in pbar-p collisions at roots=1800 GeV. The events are characterized by a leading antiproton and a large rapidity gap on the outgoing proton side. We find that the differential production cross section agrees in shape with predictions based on Regge theory and factorization, and that the ratio of double-Pomeron exchange to single diffractive production rates is relatively unsuppressed as compared to the O(10) suppression factor previously measured in single diffractive production.

We investigate the final state of large missing transverse energy and one or two high energy jets. We compare the data with the predictions from a (3+1+n)-dimensional Kaluza-Klein scenario in which gravity becomes strong at the TeV scale. At 95% confidence level (C.L.) for n=2, 4, and 6 we exclude an effective Planck scale below 1.0, 0.77, and 0.71 TeV, respectively.

Abstract: We present the results of a search for pair production of scalar top quarks ((t) over tilde (1)) in an R-parity violating supersymmetry scenario in 106 pb(-1) of p (p) over bar collisions at roots=1.8 TeV collected by the Collider Detector at Fermilab. In this mode each (t) over tilde (1) decays into a tau lepton and a b quark. We search for events with two tau's, one decaying leptonically (e or mu) and one decaying hadronically, and two jets. No candidate events pass our final selection criteria. We set a 95% confidence level lower limit on the (t) over tilde (1) mass at 122 GeV/c(2) for Br((t) over tilde (1)-->taub)=1.

Abstract: We report on measurements of differential cross sections d sigma /dp/sub T/ for prompt charm meson production in pp collisions at square root s=1.96 TeV using 5.8+or-0.3 pb/sup -1/ of data from the CDF II detector at the Fermilab Tevatron. The data are collected with a new trigger that is sensitive to the long lifetime of hadrons containing heavy flavor. The charm meson cross sections are measured in the central rapidity region |y| lt or=1 in four fully reconstructed decay modes: D/sup 0/ to K/sup -/ pi /sup +/, D/sup *+/ to D/sup 0/ pi /sup +/, D/sup +/ to K/sup -/ pi /sup +/ pi /sup +/, D/sub s//sup +/ to phi pi /sup +/, and their charge conjugates. The measured cross sections are compared to theoretical calculations.

Abstract: We report on a search for the flavor-changing neutral current decay D/sup 0/ to mu /sup +/ mu /sup -/ in pp collisions at square root s=1.96 TeV using 65 pb/sup -1/ of data collected by the CDF II experiment at the Fermilab Tevatron Collider. A displaced-track trigger selects long-lived D/sup 0/ candidates in the D/sup 0/ to mu /sup +/ mu /sup -/ search channel, the kinematically similar D/sup 0/ to pi /sup +/ pi /sup -/ channel used for normalization, the Cabibbo-favored D/sup 0/ to K/sup -/ pi /sup +/ channel used to optimize the selection criteria in an unbiased manner, and their charge conjugates. Finding no signal events in the D/sup 0/ to mu /sup +/ mu /sup -/ search window, we set an upper limit on the branching fraction B(D/sup 0/ to mu /sup +/ mu /sup -/) lt or=2.5*10/sup -6/ (3.3*10/sup -6/) at the 90% (95%) confidence level.

Abstract: We report a search for the production of long-lived charged massive particles in a data sample of 90 pb(-1) of roots = 1.8 TeV p (p) over bar collisions recorded by the Collider Detector at Fermilab. The search uses the muonlike penetration and anomalously high ionization energy loss signature expected for such a particle to discriminate it from backgrounds. The data are found to agree with background expectations, and cross section limits of O(1) pb are derived using two reference models, a stable quark and a stable scalar lepton.

Abstract: We report the results of a search for a W-' boson produced in p (p) over bar collisions at a center-of-mass energy of 1.8 TeV using a 106 pb(-1) data sample recorded by the Collider Detector at Fermilab. We observe no significant excess of events above background for a W' boson decaying to a top and bottom quark pair. In a model where this boson would mediate interactions involving a massive right-handed neutrino (nu(R)) and have standard model strength couplings, we use these data to exclude a W' boson with mass between 225 and 536 GeV/c(2) at 95% confidence level for M-W(') gt M-nuR and between 225 and 566 GeV/c(2) at 95% confidence level for M-W(') lt M-nuR.

Abstract: We have searched for pair production of the supersymmetric partner of the top quark (stop) in 107 pb(-1) of p (p) over bar collisions at roots=1.8 TeV collected by the Collider Detector at Fermilab (CDF). Each stop is assumed to decay into a lepton, bottom quark, and supersymmetric neutrino. Such a scenario would give rise to events with two leptons, two hadronic jets, and a substantial imbalance of transverse energy. No evidence of such a stop signal has been found. We exclude stop masses in the region (80less than or equal tom((t) over bar)less than or equal to135 GeV/c(2)) in the mass plane of stop versus sneutrino.

Abstract: We report a measurement of the strong coupling constant, alpha(s)(M-Z), extracted from inclusive jet production in p (p) over bar collisions at root(s) = 1800 GeV. The QCD prediction for the evolution of alpha(s) with jet transverse energy E-T is tested over the range 40 lt E-T lt 450 GeV using E-T for the renormalization scale. The data show good agreement with QCD in the region below 250 GeV. The value of as at the mass of the Z(0) boson averaged over the range 40 lt E-T lt 250 GeV is found to be alpha(s)(M-Z) = 0.1178 +/- 0.0001(stat)(- 0.0095)(+0.0081)(expt. syst). The associated theoretical uncertainties are mainly due to the choice of renormalization scale ((+6%)(-4%)) and input parton distribution functions (5%).

Abstract: We have performed a search for radiative b-hadron decays using events produced in p (p) over bar collisions at roots=1.8 TeV and collected by the Collider Detector at Fermilab. The decays we considered were (B) over bar (0)(d)→(K) over bar*(0)(→K(-)pi(+))gamma, (B) over bar (0)(s)→phi(→K+K-)gamma, Lambda(b)(0)→Lambda(→ppi(-))gamma, and their charge conjugates. Two independent methods to identify photons from such decays were employed. In the first method, the photon was detected in the electromagnetic calorimeter. In the second method, the photon was identified by an electron-positron pair produced through the external photon conversion before the tracking detector volume. By combining the two methods we obtain upper limits on the branching fractions for the (B) over bar (0)(d), (B) over bar (0)(s), and Lambda(b)(0) radiative decays which, at the 95% confidence level, are found to be B((B) over bar (0)(d)→(K) over bar*(0)gamma) lt 1.4x10(-4), B((B) over bar (0)(s)→phigamma) lt 1.6x10(-4), and B(Λ(0)(b)→Lambdagamma) lt 1.9x10(-3).

Abstract: The exclusive gammais not an element of(T) signal has a small standard model cross section and is thus a channel sensitive to new physics. This signature is predicted by models with a superlight gravitino or with large extra spatial dimensions. We search for such signals at the Collider Detector at Fermilab, using 87 pb(-1) of data at roots = 1.8 TeV, and extract 95% C.L. limits on these processes. A limit of 221 GeV is set on the scale \F\(1/2) in supersymmetric models. For 4, 6, and 8 extra dimensions, model-dependent limits on the fundamental mass scale M-D of 0.55, 0.58, and 0.60 TeV, respectively, are found. We also specify a "pseudo-model-independent" method of comparing the results to theoretical predictions.

Abstract: We present a measurement of the cross section and the first measurement of the heavy flavor content of associated direct photon + muon events produced in hadronic collisions. These measurements come from a sample of 1.8 TeV pp̄ collisions recorded with the Collider Detector at Fermilab. Quantum chromodynamics (QCD) predicts that these events are primarily due to the Compton scattering process cg→cγ, with the final-state charm quark producing a muon. The cross section for events with a photon transverse momentum between 12 and 40 GeV/c is measured to be 46.8±6.3±7.5 pb, which is two standard deviations below the most recent theoretical calculation. A significant fraction of the events in the sample contain a final-state bottom quark. The ratio of charm to bottom production is measured to be 2.4±1.2, in good agreement with QCD models. © 2001 The American Physical Society.

Abstract: We present a detailed examination of the heavy flavor content of the W+jet data sample collected with the Collider Detector at Fermilab during the 1992-1995 collider run at the Fermilab Tevatron. Jets containing heavy flavor quarks are selected via the identification of secondary vertices or semileptonic decays of b and c quarks. There is generally good agreement between the rates of secondary vertices and soft leptons in the data and in the standard model simulation including single and pair production of top quarks. An exception is the number of events in which a single jet has both a soft lepton and a secondary vertex tag. In W+ 2,3 jet data, we find 13 such events where we expected 4.47plusmn;0.6 events. The kinematic properties of this small sample of events are statistically difficult to reconcile with the simulation of standard model processes. © 2002 The American Physical Society.

Abstract: We report a measurement of the ratio of the bottom quark production cross section in antiproton-proton collisions at √s = 630 GeV to 1800 GeV using bottom quarks with transverse momenta greater than 10.75 GeV identified through their semileptonic decays and long lifetimes. The measured ratio σ(630)/σ(1800) = 0.171±.024±.012 is in good agreement with next-to-leading order quantum chromodynamics. © 2002 The American Physical Society.

Abstract: We have performed a search for gluinos ((g) over tilde) and scalar quarks ((q) over tilde) in a data sample of 84 pb(-1) of p (p) over bar collisions at roots = 1.8 TeV, recorded by the Collider Detector at Fermilab. We investigate the final state of large missing transverse energy and three or more jets, a characteristic signature in R-parity-conserving supersymmetric models. The analysis has been performed "blind," in that the inspection of the signal region is made only after the predictions from standard model backgrounds have been calculated. Comparing the data with predictions of constrained supersymmetric models, we exclude gluino masses below 195 GeV/c(2) (95% C.L.), independent of the squark mass. For the case m((q) over bar) approximate to m((g) over tilde), gluino masses below 300 GeV/c(2) are excluded.

Abstract: We present measurements of the B+ meson total cross section and differential cross section dsigma/dp(T). The measurements use a 98+/-4 pb(-1) sample of p (p) over bar collisions at roots = 1.8 TeV collected by the CDF detector. Charged B meson candidates are reconstructed through the decay B+/- → J/psiK(+/-) with J/psi → mu(+)mu(-). The total cross section, measured in the central rapidity region \y\ lt 1.0 for p(T)(B) gt 6.0 GeV/c, is 3.6+/-0.6(stat + syst) mub. The measured differential cross section is substantially larger than typical QCD predictions calculated to next-to-leading order.

Abstract: We have measured the cross sections d2σ/d P Tdη) for production of isolated direct photons in pp̄ collisions at two different center-of-mass energies, 1.8 TeV and 0.63 TeV, using the Collider Detector at Fermilab. The normalization of both data sets agrees with the predictions of quantum chromodynamics for a photon transverse momentum (PT) of 25 GeV/c, but the shapes versus photon PT do not. These shape differences lead to a significant disagreement in the ratio of cross sections in the scaling variable xT(≡ 2PT/√s). This disagreement in the xT ratio is difficult to explain with conventional theoretical uncertainties such as scale dependence and parton distribution parametrizations. © 2002 The American Physical Society.

Abstract: We present the first general search for new heavy particles, X, which decay via X → WZ(0) → enu + jj as a function of M-X and Gamma(X) in p(p) over bar collisions at roots = 1.8 TeV. No evidence is found for production of X in 110 pb(-1) of data collected by the Collider Detector at Fermilab. General cross section limits are set at the 95% C.L. as a function of mass and width of the new particle. The results are further interpreted as mass lit-nits on the production of new heavy charged vector bosons which decay via W' → WZ(0) in an extended gauge model as a function of the width, Gamma(W'), and mixing factor between the W' and the standard model W bosons.

Abstract: We present searches for quark-lepton compositeness and a heavy W' boson at high electron-neutrino transverse mass. We use similar to 110 pb(-1) of data collected in pp collisions at roots = 1.8 TeV by the CDF Collaboration during 1992-1995. The data are consistent with standard model expectations. Limits are set on the quark-lepton compositeness scale A, the ratio of partial cross sections sigma (W' → e nu)/sigma (W → e nu), and the mass of a W' boson with standard model couplings. We exclude Lambda lt 2.81 TeV and a W' boson with mass below 754 GeV/c(2) at the 95% confidence level. Combining with our previously published limit obtained using the muon channel, we exclude a W' boson with mass below 786 GeV/c(2) at the 95% confidence level.

Abstract: We report on a search for the supersymmetric partner of the top quark (top squark) produced in t (t) over bar events using 110 ph(-1) of p (p) over bar collisions at roots = 1.8 TeV recorded with the Collider Detector at Fermilab. In the case of a light top squark, the decay of-the top quark into a top squark plus the lightest supersymmetric particle (LSP) could have a significant branching ratio. The observed events are consistent with standard model t (t) over bar production and decay. Hence, we set limits on the branching ratio of the top quark decaying into a top squark plus LSP, excluding branching ratios above 45% for a LSP mass up to 30 GeV/c(2)

Abstract: We present the results of a starch for neutral Higgs bosons produced in association with b quarks in p (p) over bar → b (b) over barb (b) over bar final states with 91 +/- 7 pb(-1) of p (p) over bar collisions at roots = 1.8 TeV recorded by the Collider Detector at Fermilab. 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.

Abstract: We present a measurement of the inclusive jet cross section using the Run II cone algorithm and data collected by the D0 experiment in pp̄ collisions at a center-of-mass energy √s=1.96TeV, corresponding to an integrated luminosity of 0.70fb -1. 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: We present results of searches for diphoton resonances produced both inclusively and also in association with a vector boson (W or Z) using 100 pb(-1) of p (p) over bar collisions using the CDF detector. We set upper limits on the product of cross section times branching ratio for both p (p) over bar → gamma gamma +X and p (p) over bar → gamma gamma+ W/Z. Comparing the inclusive production to the expectations from heavy sgoldstinos we derive limits on the supersymmetry-breaking scale rootF in the TeV range, depending on the sgoldstino mass and the choice of other parameters. Also. using a NLO prediction for the associated production of a Higgs boson with a W or Z boson, we set an upper limit on the branching ratio for H → gamma gamma. Finally, we set a lower limit on the mass of a "bosophilic" Higgs boson (e.g., one which couples only to gamma, W, and Z bosons with standard model couplings) of 82 GeV/c(2) at 95% confidence level.

Abstract: We update the measurement of the t (t) over bar production cross section using the CDF detector at the Fermilab Tevatron. This measurement uses t (t) over bar decays to the final states e + nu + jets and mu + nu + jets. We search for b quarks from t decays via secondary-vertex identification or the identification of semileptonic decays of the b and cascade c quarks. The background to the t (t) over bar production is determined primarily through a Monte Carlo simulation. However, we calibrate the simulation and evaluate its uncertainty using several independent data samples. For a top quark mass of 175 GeV/c(2), we measure sigma (t (t) over bar)-=5.1 +/- 1.5 pb and sigma (t (t) over bar)=9.2 +/- 4.3 pb using the secondary vertex and the lepton tagging algorithms, respectively. Finally, we combine these results with those from other t (t) over bar decay channels and obtain sigma (t (t) over bar)-= 6.5 (+1.7)(-1.4)pb

Abstract: A measurement is presented of the two-jet differential cross section d(3)sigma /dE(T)d eta (1)d eta (2) at center of mass energy roots = 1800 GeV in p (p) over bar collisions. The results are based on an integrated luminosity of 86 pb(-1) collected during 1994 to 1995 by the CDF Collaboration at the Fermilab Tevatron collider. The differential cross section is measured as a function of the transverse energy E-T of a jet in the pseudorapidity region 0.1 lt \ [eta](1)\ lt 0.7 for four different pseudorapidity bins of a second jet restricted to 0.1 lt \ eta (2) \ lt 3.0. The results are compared with next-to- leading order QCD calculations determined using the CTEQ4 and MRST sets of parton distribution functions. None of the sets ex.amined in this analysis provides a good description of the data
