Abstract: We present the first general measurements (invariant-mass, transverse-energy, and angular distributions) of the process, {bar p}p{r_arrow}{gamma}+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. {copyright} {ital 1997} {ital The American Physical Society}

Abstract: A strong signal for double parton (DP) scattering is observed in a 16pb−1 sample of p¯p→γ/π0+3jets+X data from the CDF experiment at the Fermilab Tevatron. In DP events, two separate hard scatterings take place in a single p¯p collision. We isolate a large sample of data (∼14000events) of which 53% are found to be DP. The process-independent parameter of double parton scattering, σeff, is obtained without reference to theoretical calculations by comparing observed DP events to events with hard scatterings in separate p¯p collisions. The result σeff=(14.5±1.7−2.3+1.7)mb represents a significant improvement over previous measurements, and is used to constrain simple models of parton spatial density. The Feynman x dependence of σeff is investigated and none is apparent. Further, no evidence is found for kinematic correlations between the two scatterings in DP events.

Abstract: We present measurements of correlated $b\overline{b}$ cross sections, $\ensuremath{\mu}\ensuremath{-}\ensuremath{\mu}$ correlations, the average ${B}^{0}{\overline{B}}^{0}$ mixing parameter $\overline{\ensuremath{\chi}}$, and a limit on the CP-violating parameter ${\ensuremath{\epsilon}}_{B}.$ For these measurements, we use muon pairs from $b\overline{b}$ double semileptonic decays. The data used in this analysis were taken with the Collider Detector at Fermilab and represent an integrated luminosity of $17.4\ifmmode\pm\else\textpm\fi{}0.6$ pb${}^{\ensuremath{-}1}$. The results concerning $b\overline{b}$ production correlations are compared to predictions of next-to-leading order QCD computations.

Abstract: We calculate second and fourth order quark number susceptibilities for 2+1 flavor QCD in the high temperature region. In our study we use two improved staggered fermion formulations, namely the highly improved staggered quark formulation, and the so-called p4 formulation, as well as several lattice spacings. Second order quark number susceptibilities are calculated using both improved staggered fermion formulations, and we show that in the continuum limit the two formulations give consistent results. The fourth order quark number susceptibilities are studied only using the p4 formulation and at non-zero lattice spacings. We compare our results on quark number susceptibilities with recent weak coupling calculations, and find that these agree reasonably well with the lattice calculations within the estimated uncertainties., Comment: RevTeX, 9 pages, 5 figures, the discussion of the comparison with the perturbative results is revised and the conclusion about the validity of the perturbative approaches is modified, published version

Abstract: We report a measurement of the ratios of the decay rates of the ${B}^{+}$, ${B}^{0}$, and ${B}_{s}^{0}$ mesons into exclusive final states containing a $\frac{J}{\ensuremath{\psi}}$ meson. The final states were selected from 19.6 pb-1 of $p\overline{p}$ collisions recorded by the Collider Detector at Fermilab. These data are interpreted to determine the $b$ quark fragmentation fractions ${f}_{u}$, ${f}_{d}$, and ${f}_{s}$. We also determine the branching fractions for the decay modes ${B}^{+}\ensuremath{\rightarrow}\frac{J}{\ensuremath{\psi}{K}^{+}}$, ${B}^{+}\ensuremath{\rightarrow}\frac{J}{\ensuremath{\psi}{K}^{*}{(892)}^{+}}$, ${B}^{0}\ensuremath{\rightarrow}\frac{J}{\ensuremath{\psi}{K}^{0}}$, ${B}^{0}\ensuremath{\rightarrow}\frac{J}{\ensuremath{\psi}{K}^{*}{(892)}^{0}}$, and ${B}_{s}^{0}\ensuremath{\rightarrow}\frac{J}{\ensuremath{\psi}\ensuremath{\varphi}(1020)}$. We discuss the implications of these measurements to $B$ meson decay models.

6. Magnetic equation of state in (2+1)-flavor QCD

Abstract: A first study of critical behavior in the vicinity of the chiral phase transition of ($2+1$)-flavor QCD is presented. We analyze the quark mass and volume dependence of the chiral condensate and chiral susceptibilities in QCD with two degenerate light quark masses and a strange quark. The strange quark mass (${m}_{s}$) is chosen close to its physical value; the two degenerate light quark masses (${m}_{l}$) are varied in a wide range $1/80\ensuremath{\le}{m}_{l}/{m}_{s}\ensuremath{\le}2/5$, where the smallest light quark mass value corresponds to a pseudoscalar Goldstone mass of about 75 MeV. All calculations are performed with staggered fermions on lattices with temporal extent ${N}_{\ensuremath{\tau}}=4$. We show that numerical results are consistent with $O(N)$ scaling in the chiral limit. We find that in the region of physical light quark mass values, ${m}_{l}/{m}_{s}\ensuremath{\simeq}1/20$, the temperature and quark mass dependence of the chiral condensate is already dominated by universal properties of QCD that are encoded in the scaling function for the chiral order parameter, the magnetic equation of state. We also provide evidence for the influence of thermal fluctuations of Goldstone modes on the chiral condensate at finite temperature. At temperatures below, but close to the chiral phase transition at vanishing quark mass, this leads to a characteristic dependence of the light quark chiral condensate on the square root of the light quark mass.

Abstract: We study the finite temperature transition in QCD with three flavors of equal masses using the R and RHMC algorithms on lattices with temporal extent ${N}_{\ensuremath{\tau}}=4$ and 6. For the transition temperature in the continuum limit we find ${r}_{0}{T}_{c}=0.429(8)$ for the light pseudoscalar mass corresponding to the endpoint of the 1st order transition region. When comparing the results obtained with the R and RHMC algorithms for p4fat3 action we see no significant step-size errors down to a lightest pseudoscalar mass of ${m}_{\mathrm{ps}}{r}_{0}=0.4$.

Abstract: We present a detailed calculation of the transition temperature in QCD with two light and one heavier (strange) quark mass on lattices with temporal extent N_t =4 and 6. Calculations with improved staggered fermions have been performed for various light to strange quark mass ratios in the range, 0.05 0) and continuum (aT = 1/N_t -> 0) limits we find for the transition temperature at the physical point T_c r_0 = 0.457(7) where the scale is set by the Sommer-scale parameter r_0 defined as the distance in the static quark potential at which the slope takes on the value, (dV_qq(r)/dr)_r=r_0 = 1.65/r_0^2. Using the currently best known value for r_0 this translates to a transition temperature T_c = 192(7)(4)MeV. The transition temperature in the chiral limit is about 3% smaller. We discuss current ambiguities in the determination of T_c in physical units and also comment on the universal scaling behavior of thermodynamic quantities in the chiral limit.

Abstract: We present data on multiple production of jets with transverse energies near 20 GeV in p (p) over bar collisions at roots=1.8 TeV. QCD calculations in the parton-shower approximation of PYTHIA and HERWIG and the next-to-leading order approximation of JETRAD are compared to the data for one, two, three, and four jet inclusive production. Transverse energy spectra and multiple jet angular and summed transverse-energy distributions are adequately described by the shower approximation while next-to-leading order calculations describe the data poorly.

Abstract: We describe a search for evidence of minimal supergravity (MSUGRA) in 92.7 pb(-1) of data collected with the D empty set detector at the Fermilab Tevatron p (p) over bar collider at roots=1.8 TeV. Events with a single electron, four or more jets, and large missing transverse energy were used in this search. The major backgrounds are from W+jets, misidentified multijet, t (t) over bar, and WW production. We observe no excess above the expected number of background events in our data. A new limit in terms of MSUGRA model parameters is obtained.

Abstract: We have measured the W boson mass using the DO detector and a data sample of 82 pb(-1) from the Fermilab Tevatron collider. This measurement uses W-->enu decays, where the electron is close to a boundary of a central electromagnetic calorimeter module. Such "edge" electrons have not been used in any previous DO analysis, and represent a 14% increase in the W boson sample size. For these electrons, new response and resolution parameters are determined, and revised backgrounds and underlying event energy flow measurements are made. When the current measurement is combined with previous DO W boson mass measurements, we obtain M-W=80.483+/-0.084 GeV. The 8% improvement from the previous DO measurement is primarily due to the improved determination of the response parameters for non-edge electrons using the sample of Z bosons with non-edge and edge electrons.

Abstract: The D empty set Collaboration has studied for the first time the properties of hadron-collider jets reconstructed with a successive-combination algorithm based on relative transverse momenta (k(perpendicular to)) of energy clusters. Using the standard value D = 1.0 of the jet-separation parameter in the k(perpendicular to) algorithm, we find that the p(T) of such jets is higher than the E-T of matched jets reconstructed with cones of radius R = 0.7, by about 5 (8) GeV at p(T) approximate to90 (240) GeV. To examine internal jet structure, the k(perpendicular to) algorithm is applied within D = 0.5 jets to resolve any subjets. The multiplicity of subjets in jet samples at roots = 1800 GeV and 630 GeV is extracted separately for gluons (M (g) ) and quarks (M q), and the ratio of average subjet multiplicities in gluon and quark jets is measured as ([M g] - 1)/([M q] - 1) = 1.84+/-0.15 (stat)(-0.18)(+0.22) (syst). This ratio is in agreement with the expectations from the HERWIG Monte Carlo event generator and a resummation calculation, and with observations in e(+) e(-) annihilations, and is close to the naive prediction for the ratio of color charges of C-A/C-F = 9/4 = 2.25.

Abstract: We measure the relative rate of production of orbitally excited (L = 1) states of B mesons (B**) by observing their decays into B pi (+/-). We reconstruct B mesons through semileptonic decay channels using data collected in p(p) over bar collisions at roots = 1.8 TeV. The fraction of light B mesons that are produced as L = 1B** states is measured to be 0.28 +/- 0.06(stat) +/- 0.03(syst). We also measure the collective mass of the B** states, and quantify the result by quoting the (model-dependent) mass of the lowest B** state to be m(B-1) = 5.71 +/- 0.02 GeV/c(2).

Abstract: Results are presented from analyses of jet data produced in $p\overline{p}$ collisions at $\sqrt{s}=630$ and 1800 GeV collected with the D\O{} detector during the 1994--1995 Fermilab Tevatron Collider run. We discuss the details of detector calibration, and jet selection criteria in measurements of various jet production cross sections at $\sqrt{s}=630$ and 1800 GeV. The inclusive jet cross sections, the dijet mass spectrum, the dijet angular distributions, and the ratio of inclusive jet cross sections at $\sqrt{s}=630$ and 1800 GeV are compared to next-to-leading-order QCD predictions. The order ${\ensuremath{\alpha}}_{\mathrm{s}}^{3}$ calculations are in good agreement with the data. We also use the data at $\sqrt{s}=1800$ GeV to rule out models of quark compositeness with a contact interaction scale less than $2.2$ TeV at the $95%$ confidence level.

Abstract: We report on a search for supersymmetry using the D\O{} detector. The 1994--1996 data sample of $\sqrt{s}=1.8$ TeV $p\overline{p}$ collisions was analyzed for events containing two leptons $(e$ or $\ensuremath{\mu}),$ two or more jets, and missing transverse energy. Assuming the minimal supergravity model, with ${A}_{0}=0$ and $\ensuremath{\mu}l0,$ various thresholds were employed to optimize the search. No events were found beyond expectation from the background. We set a lower limit at the 95% C.L. of 255 $\mathrm{GeV}{/c}^{2}$ for equal mass squarks and gluinos for $\mathrm{tan}\ensuremath{\beta}=2,$ and present exclusion contours in the ${(m}_{0}{,m}_{1/2})$ plane for $\mathrm{tan}\ensuremath{\beta}=2$--6.

Abstract: We present the first measurement of the electron angular distribution parameter α 2 in W→eν events produced in proton-antiproton collisions as a function of the W boson transverse momentum. Our analysis is based on data collected using the DO detector during the 1994–1995 Fermilab Tevatron run. We compare our results with next-to-leading order perturbative QCD, which predicts an angular distribution of (1±α 1 cosθ ∗ +α 2 cos 2 θ ∗ ), where θ ∗ is the polar angle of the electron in the Collins-Soper frame. In the presence of QCD corrections, the parameters α 1 and α 2 become functions of p T W , the W boson transverse momentum. This measurement provides a test of next-to-leading order QCD corrections which are a non-negligible contribution to the W boson mass measurement.

Abstract: We present a search for electroweak production of single top quarks in the electron+jets and muon+jets decay channels. The measurements use ≈90pb -1 of data from Run 1 of the Fermilab Tevatron collider, collected at 1.8 TeV with the DO detector between 1992 and 1995. We use events that include a tagging muon, implying the presence of a b jet, to set an upper limit at the 95% confidence level on the cross section for the s-channel process pp→tb+X of 39 pb. The upper limit for the t-channel process pp→tqb+X is 58 pb.

Abstract: The result of a search for gaugino pair production with a trilepton signature is reinterpreted in the framework of minimal supergravity (MSUGRA) with R-parity violation via leptonic lambda Yukawa couplings. The search used 95 pb(-1) of p (p) over bar collisions at root s = 1.8 TeV recorded by the D empty set detector at the Fermilab Tevatron. A large domain of the MSUGRA parameter space is excluded for lambda(121), lambda(122)greater than or equal to 10(-4).

Abstract: This paper reports an updated measurement of the standard model CP violation parameter sin 2{beta} using the CDF Detector at Fermilab. The entire run I data sample of 110 pb{sup -1} of proton-antiproton collisions at {radical}(s)=1.8 TeV is used to identify a signal sample of {approx}400 B{yields}J/{psi} K{sub S}{sup 0} events, where J/{psi}{yields}{mu}{sup +}{mu}{sup -} and K{sub S}{sup 0}{yields}{pi}{sup +}{pi}{sup -}. The flavor of the neutral B meson is identified at the time of production by combining information from three tagging algorithms: a same-side tag, a jet-charge tag, and a soft-lepton tag. A maximum likelihood fitting method is used to determine sin 2{beta}=0.79{sub -0.44}{sup +0.41}(stat+syst). This value of sin 2{beta} is consistent with the standard model prediction, based upon existing measurements, of a large positive CP-violating asymmetry in this decay mode.

Abstract: We report on measurements on inclusive cross sections times branching fractions into electrons for W and Z bosons produced in p (p) over bar collisions at root s = 1.8 TeV. From an integrated luminosity of 84.5 pb(-1) recorded in 1994-1995 using the D empty set detector at the Fermilab Tevatron, we determine sigma(p (p) over bar--> W + X) x B(W-->e nu) = 2310 +/- 10(stat) +/- 50(syst) +/- 100(lum)pb and sigma(p (p) over bar-->Z + X) x B(Z-->ee)=221+/-3(stat)+/-4(syst)+/-10(lum)pb. From these, we derive sigma(p (p) over bar-->W + X) x B(N-->e nu)/sigma(p (p) over bar-->Z + X) x B(Z-->ee) = 10.43+/-0.15(stat) +/- 0.20(syst) +/- 0.10(NLO), B(W-->e nu) = 0.1044+/-0.0015(stat)+/-0.0020(syst)+/-0.0017(theory)+/-0.0010(NLO). and Gamma(w) = 2169 +/- 0.03 l(stat) +/- 0.042(syst) +/- 0.041(theory)+/- 0.022(NLO)GeV. We use the latter to set a 95% confidence level upper limit on the partial decay width of the W boson into nonstandard model final states, Gamma(W)(inv), of 0.213 GeV. Combining these results with those from the 1992-1993 data gives sigma(p (p) over bar-->W+X) x B(W-->e nu)/sigma(p (p) over bar-->Z+X) x B(Z-->ee) = 10.51+/-0.25, Gamma(W) = 2.152 +/- 0.066 GeV, and a 95% C.L. upper limit an Gamma(W)(inv) of 0.191 GeV. Using a sample with a luminosity of 505 nb(-1) taken at root s = 630 GeV, we measure sigma(p (p) over bar--> W+ X) x B(W --> e nu) = 658 +/- 67 pb.

Abstract: We present a measurement of the differential cross section as a function of transverse momentum of the Z boson in ppbar collisions at sqrt{s}=1.8 TeV using data collected by the D0 experiment at the Fermilab Tevatron Collider during 1994--1996. We find good agreement between our data and the NNLO resummation prediction and extract values of the non-perturbative parameters for the resummed prediction from a fit to the differential cross section.

Abstract: The oscillation frequency {delta}m{sub d} of B{sup 0}B(bar sign){sup 0} mixing is measured using the partially reconstructed semileptonic decay B(bar sign){sup 0}{yields}l{sup -}{nu}(bar sign)D{sup *+}X. The data sample was collected with the CDF detector at the Fermilab Tevatron collider during 1992-1995 by triggering on the existence of two lepton candidates in an event, and corresponds to about 110 pb{sup -1} of p(bar sign)p collisions at {radical}(s)=1.8 TeV. We estimate the proper decay time of the B(bar sign){sup 0} meson from the measured decay length and reconstructed momentum of the l{sup -}D{sup *+} system. The charge of the lepton in the final state identifies the flavor of the B(bar sign){sup 0} meson at its decay. The second lepton in the event is used to infer the flavor of the B(bar sign){sup 0} meson at production. We measure the oscillation frequency to be {delta}m{sub d}=0.516{+-}0.099{sub -0.035}{sup +} {sup 0.029} ps{sup -1}, where the first uncertainty is statistical and the second is systematic.

Abstract: A new technique to measure the ratio of b quark fragmentation fractions in $p\overline{p}$ collisions is described. Using a ${70\ensuremath{-}\mathrm{p}\mathrm{b}}^{\mathrm{\ensuremath{-}}1}$ sample of low-mass dimuon trigger data recorded with the Collider Detector at Fermilab, we identify B mesons by observing the double semileptonic decays $\stackrel{\ensuremath{\rightarrow}}{b}c\ensuremath{\mu}X$ with $\stackrel{\ensuremath{\rightarrow}}{c}s\ensuremath{\mu}X.$ By counting the numbers of ${K}^{*}{(892)}^{0},$ ${K}^{*}{(892)}^{+},$ and \ensuremath{\varphi}(1020) mesons produced in association with these muon pairs, we measure the ratio of strange to nonstrange B meson production to be ${f}_{s}{/(f}_{u}{+f}_{d})=[21.0\ifmmode\pm\else\textpm\fi{}3.6(\mathrm{stat}{)}_{\ensuremath{-}3.0}^{+3.8}(\mathrm{syst})]%.$ This measurement is the most precise available from hadron collisions to date. Limits on the branching fractions of semileptonic charm meson decays with ${K}_{1}(1270),$ ${K}_{1}^{*}(1410),$ and ${K}_{2}^{*}(1430)$ mesons in the final state are also obtained.

Abstract: We present a measurement of the mass difference {Delta}m{sub d} for the B{sup 0} meson and the statistical power of the b flavor tagging methods used. The measurement uses 90 pb{sup -1} of data from p{ovr p} collisions at sqrt[s]=1.8 TeV collected with the CDF detector. An inclusive lepton trigger is used to collect a large sample of B hadron semileptonic decays. The mass difference {Delta}m{sub d} is determined from the proper time dependence of the fraction of B hadrons that undergo flavor oscillations. The flavor at decay is inferred from the charge of the lepton from semileptonic B decay. The initial flavor is inferred by determining the flavor of the other B hadron produced in the collision, either from its semileptonic decay (soft-lepton tag) or from its jet charge. The measurement yields {Delta}m{sub d}=(0.500{+-}0.052{+-}0.043){Dirac_h} ps{sup -1}, where the first uncertainty is statistical and the second uncertainty is systematic. The statistical powers ({var_epsilon}D{sup 2}) of the soft-lepton and jet-charge flavor taggers are (0.91{+-}0.10{+-}0.11)% and (0.78{+-}0.12{+-}0.08)%, respectively.

Abstract: Evidence of anomalous WW and WZ production was sought in pbar{p} collisions at a center-of-mass energy of sqrt(s) = 1.8 TeV. The final states $WW (WZ) to mu-nu-jet-jet + X, WZ to mu-nu-e-e + X and WZ to e-nu-e-e + X were studied using a data sample corresponding to an integrated luminosity of approximately 90 pb-1. No evidence of anomalous diboson production was found. Limits were set on anomalous WWgamma and WWZ couplings and were combined with our previous results. The combined 95% confidence level anomalous coupling limits for Lambda=2 TeV are -0.25 LE Delta-kappa LE 0.39 (lambda=0) and -0.18 LE lambda LE 0.19 (Delta \kappa = 0), assuming the WWgamma couplings are equal to the WWZ couplings.

Abstract: D\O{} has measured the inclusive production cross section of W and Z bosons in a sample of 13 ${\mathrm{pb}}^{\ensuremath{-}1}$ of data collected at the Fermilab Tevatron. The cross sections, multiplied by their leptonic branching fractions, for production in $p\overline{p}$ collisions at $\sqrt{s}=1.8$ TeV are ${\ensuremath{\sigma}}_{W}\mathrm{B}(\stackrel{\ensuremath{\rightarrow}}{W}e\ensuremath{\nu})=2.36\ifmmode\pm\else\textpm\fi{}0.02\ifmmode\pm\else\textpm\fi{}0.08\ifmmode\pm\else\textpm\fi{}0.13\mathrm{}\mathrm{nb},$ ${\ensuremath{\sigma}}_{W}\mathrm{B}(\stackrel{\ensuremath{\rightarrow}}{W}\ensuremath{\mu}\ensuremath{\nu})=2.09\ifmmode\pm\else\textpm\fi{}0.06\ifmmode\pm\else\textpm\fi{}0.22\ifmmode\pm\else\textpm\fi{}0.11\mathrm{}\mathrm{nb},$ ${\ensuremath{\sigma}}_{Z}\mathrm{B}(\stackrel{\ensuremath{\rightarrow}}{Z}{e}^{+}{e}^{\ensuremath{-}})=0.218\ifmmode\pm\else\textpm\fi{}0.008\ifmmode\pm\else\textpm\fi{}0.008\ifmmode\pm\else\textpm\fi{}0.012\mathrm{}\mathrm{nb}$, and ${\ensuremath{\sigma}}_{Z}\mathrm{B}(\stackrel{\ensuremath{\rightarrow}}{Z}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}})=0.178\ifmmode\pm\else\textpm\fi{}0.022\ifmmode\pm\else\textpm\fi{}0.021\ifmmode\pm\else\textpm\fi{}0.009\mathrm{}\mathrm{nb}$, where the first uncertainty is statistical and the second systematic; the third reflects the uncertainty in the integrated luminosity. For the combined electron and muon analyses, we find ${\ensuremath{\sigma}}_{W}\mathrm{B}(\stackrel{\ensuremath{\rightarrow}}{W}l\ensuremath{\nu})/{\ensuremath{\sigma}}_{Z}\mathrm{B}(\stackrel{\ensuremath{\rightarrow}}{Z}{l}^{+}{l}^{\ensuremath{-}})=10.90\ifmmode\pm\else\textpm\fi{}0.52$. Assuming standard model couplings, we use this result to determine the width of the W boson, and obtain $\ensuremath{\Gamma}(W)=2.044\ifmmode\pm\else\textpm\fi{}0.097 \mathrm{GeV}$.

Abstract: ${B}_{d}^{0}\ensuremath{-}{B}_{d}^{0}$ oscillations are observed in ``self-tagged'' samples of partially reconstructed $B$ mesons decaying into a lepton and a charmed meson collected in $p\overline{p}$ collisions at $\sqrt{s}=1.8\mathrm{TeV}.$ A flavor tagging technique is employed which relies upon the correlation between the flavor of $B$ mesons and the charge of a nearby particle. We measure the flavor oscillation frequency to be $\ensuremath{\Delta}{m}_{d}{=0.471}_{\ensuremath{-}0.068}^{+0.078}\ifmmode\pm\else\textpm\fi{}0.034{\mathrm{ps}}^{\mathrm{\ensuremath{-}}1}.$ The tagging method is also demonstrated in exclusive samples of ${B}_{u}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}{K}^{+}$ and ${B}_{d}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}{K}^{*0}(892),$ where similar flavor-charge correlations are observed. The tagging characteristics of the various samples are compared with each other, and with Monte Carlo simulations.

Abstract: We report on a search for bottom squarks produced in pbarp collisions at sqrt(s) = 1.8 TeV using the D0 detector at Fermilab. Bottom squarks are assumed to be produced in pairs and to decay to the lightest supersymmetric particle (LSP) and a b quark with branching fraction of 100%. The LSP is assumed to be the lightest neutralino and stable. We set limits on the production cross section as a function of bottom squark mass and LSP mass.

Abstract: We present a measurement of Z 0 boson and Drell-Yan production cross sections in pp collisions at √s =1.8TeV using a sample of 107 pb -1 accumulated by the Collider Detector at Fermilab. The Drell-Yan cross section is measured in the mass range of M μμ > 40GeV/c 2 . We compare the measurements with the predictions of quantum chromodynamics in both leading order and next-to-leading order, incorporating the recent parton distribution functions. The measurements are consistent with the standard model expectations. ©1999 The American Physical Society.

Abstract: The lifetimes of the ${B}^{\ensuremath{-}}$ and ${B}^{0}$ mesons are measured using the partially reconstructed semileptonic decays $\overline{B}\ensuremath{\rightarrow}{\mathrm{Dl}}^{\ensuremath{-}}\overline{\ensuremath{\nu}}X,$ where $D$ is either a ${D}^{0}$ or ${D}^{*+}$ meson. The data were collected by the CDF detector at the Fermilab Tevatron collider during 1992--1995 and correspond to about $110{\mathrm{pb}}^{\mathrm{\ensuremath{-}}1}$ of $\overline{p}p$ collisions at $\sqrt{s}=1.8\mathrm{TeV}.$ We measure decay lengths and extract the lifetimes to be $\ensuremath{\tau}{(B}^{\ensuremath{-}})=1.637\ifmmode\pm\else\textpm\fi{}{0.058}_{\ensuremath{-}0.043}^{+0.045}$ ps and $\ensuremath{\tau}({B}^{0})=1.474\ifmmode\pm\else\textpm\fi{}{0.039}_{\ensuremath{-}0.051}^{+0.052}\mathrm{ps},$ and the ratio of the lifetimes to be $\ensuremath{\tau}{(B}^{\ensuremath{-}})/\ensuremath{\tau}({B}^{0})=1.110\ifmmode\pm\else\textpm\fi{}{0.056}_{\ensuremath{-}0.030}^{+0.033},$ where the first uncertainties are statistical and the second are systematic.

Abstract: We report the observations of the decays B{sup +}{yields}{psi}(2S)K{sup +} and B{sup 0}{yields}{psi}(2S)K*(892){sup 0} in p{ovr p} collisions at a center-of-mass energy of 1.8 TeV using a 110 pb{sup -1} data sample recorded by the Collider Detector at Fermilab. We also reconstruct the decays B{sup +}{yields}J/{psi}K{sup +} and B{sup 0}{yields}J/{psi}K*(892){sup 0} and measure the six ratios of branching fractions of these four decays. The relative branching-fraction results are shown to be consistent with phenomenological factorization calculations of hadronic B-meson decays. We use the world-average branching fraction B(B{sup +}{yields}J/{psi}K{sup +}) to derive B(B{sup +}{yields}{psi}(2S)K{sup +})=(0.56{+-}0.08{+-}0.10)x10{sup -3}, B(B{sup 0}{yields}{psi}(2S)K*(892){sup 0})=(0.92{+-}0.20{+-}0.16)x10{sup -3}, and B(B{sup 0}{yields}J/{psi}K*(892){sup 0})=(1.78{+-}0.14{+-}0.29)x10{sup -3}, where the first and second uncertainties are statistical and systematic, respectively.

Abstract: We search for new long-lived particles which decay to Z{sup 0} bosons by looking for Z{sup 0}{yields}e{sup +}e{sup -} decays with displaced vertices. We find no evidence for parent particles of the Z{sup 0} with long lifetimes in 90 pb{sup -1} of data from the CDF experiment at Fermilab. We set a cross section limit as a function of the lifetime of the parent particle for both a generic Z{sup 0} parent and a fourth-generation, charge -1/3 quark that decays into Z{sup 0}b.

Abstract: We calculate the QCD equation of state for temperatures corresponding to the transition region with physical mass values for two degenerate light quark flavors and a strange quark using an improved staggered fermion action (p4-action) on lattices with temporal extent N_tau=8. We compare our results with previous calculations performed at twice larger values of the light quark masses as well as with results obtained from a resonance gas model calculation. We also discuss the deconfining and chiral aspects of the QCD transition in terms of renormalized Polyakov loop, strangeness fluctuations and subtracted chiral condensate. We show that compared to the calculations performed at twice larger value of the light quark mass the transition region shifts by about 5 MeV toward smaller temperatures, Comment: 7 pages, LaTeX, 6 figures; minor corrections, typos corrected, references added
