Abstract: We present a measurement of the Drell-Yan cross section at high dielectron invariant mass using 120/pb of data collected in pbar-p collisions at sqrt(s) = 1.8 TeV by the D0 collaboration during 1992-96. No deviation from standard model expectations is observed. We use the data to set limits on the energy scale of quark-electron compositeness with common constituents. The 95% confidence level lower limits on the compositeness scale vary between 3.3 TeV and 6.1 TeV depending on the assumed form of the effective contact interaction., 6 pages, 2 figures, submitted to PRL

Abstract: This Letter describes a measurement of the muon cross section originating from b quark decay in the forward rapidity range 2.4 < y(mu) < 3.2 in pbarp collisions at sqrt(s) = 1.8 TeV. The data used in this analysis were collected by the D0 experiment at the Fermilab Tevatron. We find that NLO QCD calculations underestimate b quark production by a factor of four in the forward rapidity region. A cross section measurement using muon+jet data has been included in this version of the paper.

Abstract: We present a measurement of the transverse momentum distribution of Z bosons produced 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 a current resummation calculation. We also use our data to extract values of the non-perturbative parameters for a particular version of the resummation formalism, obtaining significantly more precise values than previous determinations.

Abstract: We search for new physics using events with one high transverse energy photon, two or more jets, and an apparent imbalance in transverse energy, in p{ovr p} collisions at the Fermilab Tevatron at {radical} (s) =1.8 TeV . Such events are predicted for production of supersymmetric particles in some models. No excess is observed beyond expected background. For the parameter space of the minimal supersymmetric standard model with branching fraction B({tilde {chi}}{sup 0}{sub 2}{r_arrow}{gamma}thinsp{tilde {chi}}{sup 0}{sub 1})=1 and m{sub {tilde {chi}}{sup 0}{sub 2 }}{minus}m{sub {tilde {chi}}{sup 0}{sub 1}}{gt}20 GeV , we obtain a 95{percent} confidence level lower mass limit of 310thinspthinspGeV for equal mass squarks and gluinos. The results are also interpreted in models with low energy gauge mediated supersymmetry breaking. {copyright} {ital 1998} {ital The American Physical Society }

Abstract: The shape of the transverse momentum distribution of W bosons (p_T(W)) produced in pbarp collisions at sqrt(s)= 1.8 TeV is measured with the DO detector at Fermilab. The result is compared to QCD perturbative and resummation calculations over the p_T(W) range from 0-200 GeV/c. The shape of the distribution is consistent with the theoretical prediction.

Abstract: We report a measurement of the W boson mass based on an integrated luminosity of 82 pb −1 from pp collisions at √s = 1.8 TeV recorded in 1994-1995 by the D0 detector at the Fermilab Tevatron. We identify W bosons by their decays to e∨ V and extract the mass by fitting the transverse mass spectrum from 28 323 W boson candidates. A sample of 3563 dielectron events, mostly due to Z→ee decays, constrains models of W boson production and the detector. We measure M W = 80.44±0.10(stat)±0.07(syst) GeV. By combining this measurement with our result form the 1992-1993 data set, we obtain M W = 80.43±0.11 GeV.

Abstract: We have searched for first generation scalar leptoquark (LQ) pairs in the enu+jets channel using ppbar collider data (integrated luminosity= 115 pb^-1) collected by the DZero experiment at the Fermilab Tevatron during 1992-96. The analysis yields no candidate events. We combine the results with those from the ee+jets and nunu+jets channels to obtain 95% confidence level (CL) upper limits on the LQ pair production cross section as a function of mass and of beta, the branching fraction to a charged lepton. Comparing with the next-to-leading order theory, we set 95% CL lower limits on the LQ mass of 225, 204, and 79 GeV/c^2 for beta=1, 1/2, and 0, respectively.

Abstract: We have searched for the pair production of first generation scalar leptoquarks in the $\mathrm{eejj}$ channel using the full data set $(123{\mathrm{pb}}^{\ensuremath{-}1})$ collected with the D0 detector at the Fermilab Tevatron during 1992--1996. We observe no candidates with an expected background of approximately 0.4 events. Comparing the experimental 95% confidence level upper limit to theoretical calculations of the cross section with the assumption of a 100% branching fraction of $\mathrm{eq}$, we set a lower limit on the mass of a first generation scalar leptoquark of $225\mathrm{GeV}{/c}^{2}$. The results of this analysis rule out the interpretation of the excess of high ${Q}^{2}$ events at DESY HERA as leptoquarks which decay exclusively to $\mathrm{eq}$.

Abstract: We present a measurement of the ttbar production cross section in ppbar collisions at root(s) = 1.8TeV by the D0 experiment at the Fermilab Tevatron. The measurement is based on data from an integrated luminosity of approximately 125 pb^-1 accumulated during the 1992-1996 collider run. We observe 39 ttbar candidate events in the dilepton and lepton+jets decay channels with an expected background of 13.7+-2.2 events. For a top quark mass of 173.3GeV/c^2, we measure the ttbar production cross section to be 5.5+-1.8 pb.

Abstract: A measurement of the cross section for production of single, isolated photons is reported for transverse energies in the range of 10–125 GeV for two regions of pseudorapidity, |η| -1 of integrated luminosity accumulated in pp collisions at √s=1.8TeV and recorded with the D0 detector at the Fermilab Tevatron Collider. The background, predominantly from jets which fragment to neutral mesons, is estimated using the longitudinal shower shape in the calorimeter. In both pseudorapidity regions the cross section is found to agree with the next-to-leading order QCD prediction for 30≲E T γ ≲80GeV.

Abstract: We report on a search for right-handed W bosons (W R ) with mass greater than 200GeV/c 2 . We used data collected with the D0 detector at the Fermilab Tevatron pp collider at √s=1.8TeV to search for W R decays into an electron and a massive right-handed neutrino W R ± >e ± N R . Using the inclusive electron data, we set mass limits independent of the N R decay: m W R >650GeV/c 2 and m W R >720GeV/c 2 at the 95% confidence level, valid for m N R W R and mN R «m W R , respectively. The latter also represents a new lower limit on the mass of a heavy left-handed W boson (W') decaying into ev. In addition, limits on mWR valid for larger values of the N R mass are obtained assuming that NR decays to an electron and two jets.

Abstract: We present a search for pair produced top squarks, the supersymmetric partners of the top quark, using the D0 detector at the Fermilab Tevatron pp collider. We consider a scenario in which the lighter of the two top squarks t 1 decays with 100% branching fraction to a charm quark and the lightest neutralino χ 1 0 yielding a signal of two acollinear jets with missing transverse energy. We observe 3 events while we expect 3.5±1.2 events from the known standard model processes. We exclude at the 95% confidence level a significant region of the m t 1 - m χ 1 0 parameter space. The highest m t 1 value we exclude is 93 GeV/c 2 with a corresponding m χ 1 0 value of 8 GeV/c 2 .

Abstract: We have studied J ψ production in p p collisions at s = 1.8 TeV with the DO detector at Fermilab using μ+μ− data. We have measured the inclusive J ψ production cross section as a function of J ψ transverse momentum, pT. For the kinematic range pT > 8 GeV/c and |η| σ(p p → J ψ + X) · Br ( J ψ → μ + μ − ) = 2.08 ± 0.17( stat) ± 0.46(syst) nb. Using the muon impact parameter we have estimated the fraction of J ψ mesons coming from B meson decays to be fb = 0.35 ± 0.09(stat)±0.10(syst) and inferred the inclusive b production cross section. From the information on the event topology the fraction of nonisolated J ψ events has been measured to be fnonisol = 0.64 ± 0.08(stat)±0.06(syst). We have also obtained the fraction of J ψ events resulting from radiative decays of χc states, fχ = 0.32 ± 0.07(stat)±0.07(syst). We discuss the implications of our measurements for charmonium production processes.

Abstract: A study of the particle multiplicity between jets with large rapidity separation has been performed using the D\O\ detector at the Fermilab Tevatron $p\bar{p}$ Collider operating at $\sqrt{s}=1.8$\,TeV. A significant excess of low-multiplicity events is observed above the expectation for color-exchange processes. The measured fractional excess is $1.07 \pm 0.10({\rm stat})~{ + 0.25}_{- 0.13}({\rm syst})\%$, which is consistent with a strongly-interacting color-singlet (colorless) exchange process and cannot be explained by electroweak exchange alone. A lower limit of $0.80\%$ (95\% C.L.) is obtained on the fraction of dijet events with color-singlet exchange, independent of the rapidity gap survival probability.

Abstract: We report on a search for second generation scalar leptoquarks with the D0 detector at the Fermilab Tevatron pp collider at √s = 1.8 TeV. This search is based on 12.7 pb-1 of data. Second generation leptoquarks are assumed to be produced in pairs and to decay into a neutrino and quark with branching ratio β or into a neutrino and quark with branching ratio 1 - β. We obtain cross section times branching ratio limits as a function of leptoquark mass and set lower limits on the leptoquark mass at the 95% confidence level.

Abstract: The ratio of the number of {ital W}+1 jet to {ital W}+0 jet events is measured with the D0 detector using data from the 1992--93 Tevatron Collider run. For the {ital W}{r_arrow}{ital e}{nu} channel with a minimum jet {ital E}{sub {ital T}} cutoff of 25 GeV, the experimental ratio is 0.065{plus_minus}0.003(stat){plus_minus}0.007(syst). Next-to-leading order QCD predictions for various parton distributions agree well with each other and are all over 1 standard deviation below the measurement. Varying the strong coupling constant {alpha}{sub {ital s}} in both the parton distributions and the partonic cross sections simultaneously does not remove this discrepancy. {copyright} {ital 1995} {ital The} {ital American} {ital Physical} {ital Society}.

Abstract: The distribution of the transverse energy in jets has been measured in p p collisions at s =1.8 TeV TeV using the DO detector at Fermilab. This measurement of the jet shape is made as a function of jet transverse energy in both the central and forward rapidity regions. Jets are shown to narrow both with increasing transverse energy and with increasing rapidity. Next-to-leading order partonic QCD calculations are compared to the data. Although the calculations qualitatively describe the data, they are shown to be very dependent on renormalization scale, parton clustering algorithm, and jet direction definition and they fail to describe the data in all regions consistently.

Abstract: A search for a heavy charged gauge boson, W′, using the decay channels W′ → eν and W′ → τν → eνν ν is reported. The data used in the analysis were collected by the DO experiment at the Fermilab Tevatron during the 1992-93 p p collider run from an integrated luminosity of 13.9 ± 0.8 pb−1 at s =1.8 TeV . Assuming that the neutrino from W′ decay is stable and has a mass significantly less than mW′, an upper limit at the 95% confidence level is set on the cross section times branching ratio for p p → W′ → eν .

Abstract: The results of a search for W boson pair production in p{bar p} collisions at {radical}s = 1.8 TeV with subsequent decay to dilepton (e{mu}, ee, and {mu}{mu}) channels are presented. One event is observed with an expected background of 0.56 {plus_minus} 0.13 events with an integrated luminosity of approximately 14 pb{sup {minus}1}. Assuming equal strengths for the WWZ and WW{gamma} gauge boson coupling parameters {kappa} and {lambda}, limits on the CP-conserving anomalous coupling constants are {minus}2.6 < {delta}{kappa} < 2.8 and {minus}2.1 {lambda} < 2.1 at the 95% confidence level.

Abstract: We report a measurement of the inclusive muon and {ital b}-quark production cross sections in {ital p{bar p}} collisions at {radical}{ital s}=1.8 TeV using the D0 detector at the Fermilab Tevatron collider. The inclusive muon spectrum extends over the kinematic range {vert_bar}{ital y}{sup {mu}}{vert_bar}{lt}0.8 and 3.5{lt}{ital p}{sub {ital T}}{sup {mu}}{lt}60GeV/{ital c}, and is well described by the expected contributions from various known sources. The {ital b}-quark production cross section for {vert_bar}{ital y}{sup {ital b}}{vert_bar}{lt}1.0 and {ital p}{sup {ital b}}{sub {ital T}}{gt}6GeV/{ital c} is extracted, and agrees with next-to-leading order QCD predictions within the experimental and theoretical uncertainties.

Abstract: We present new results on the search for the top quark in p anti-p collisions at S**(1/2) = 1.8 TeV with an integrated luminosity of 13.5 +- 1.6 pb**(-1). We have considered t anti-t production in the Standard Model using electron and muon dilepton decay channels (t anti-t -> e mu + jets, e e + jets, and mu mu + jets) and single-lepton decay channels (t anti-t -> e + jets and mu + jets) with and without tagging of b quark jets. From all channels, we have 9 events with an expected background of 3.8 +- 0.9. If we assume that the excess is due to t anti-t production, and assuming a top mass of 180 GeV/c**2, we obtain a cross section of 8.2 +- 5.1 pb.

Abstract: Limits on anomalous $\mathrm{WW}\ensuremath{\gamma}$ and $\mathrm{WWZ}$ couplings are presented from a study of $WW/W\stackrel{\ensuremath{\rightarrow}}{Z}e\ensuremath{\nu}\mathrm{jj}$ events produced in $p\overline{p}$ collisions at $\sqrt{s}=1.8 \mathrm{TeV}.$ Results from the analysis of data collected using the D\O{} detector during the 1993--1995 Tevatron collider run at Fermilab are combined with those of an earlier study from the 1992--1993 run. A fit to the transverse momentum spectrum of the W boson yields direct limits on anomalous $\mathrm{WW}\ensuremath{\gamma}$ and $\mathrm{WWZ}$ couplings. With the assumption that the $\mathrm{WW}\ensuremath{\gamma}$ and $\mathrm{WWZ}$ couplings are equal, we obtain $\ensuremath{-}0.34l\ensuremath{\lambda}l0.36$ (with $\ensuremath{\Delta}\ensuremath{\kappa}=0)$ and $\ensuremath{-}0.43l\ensuremath{\Delta}\ensuremath{\kappa}l0.59$ (with $\ensuremath{\lambda}=0)$ at the 95% confidence level for a form-factor scale $\ensuremath{\Lambda}=2.0 \mathrm{TeV}.$

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: 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: 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 search for charged Higgs bosons in decays of pair-produced top quarks using 109.2 +- 5.8 pb^-1 of data recorded from ppbar collisions at sqrt{s} = 1.8 TeV by the D0 detector during 1992-96 at the Fermilab Tevatron. No evidence is found for charged Higgs production, and most parts of the [m(H+),tan(beta)] parameter space where the decay t -> bH+ has a branching fraction close to or larger than that for t -> bW+ are excluded at 95% confidence level. Assuming m(t) = 175 GeV and sigma(ppbar -> ttbar) = 5.5 pb, for m(H+) = 60 GeV, we exclude tan(beta) < 0.97 and tan(beta) > 40.9., 11 pages, 3 figures, submitted to PRL

Abstract: The results of a search for W boson pair production in pp collisions at √s=1.8TeV with subsequent decay to eμ, ee, and μμ channels are presented. Five candidate events are observed with an expected background of 3.1±0.4 events for an integrated luminosity of approximately 97pb -1 . Limits on the anomalous couplings are obtained from a maximum likelihood fit of the E T spectra of the leptons in the candidate events. Assuming identical WWγ and WWZ couplings, the 95% C.L. limits are -0.62

Abstract: A measurement of the mass of the W boson is presented which is based on a sample of 5982 W → eνv decays observed in pp collisions at √s=1.8 TeV with the D∅ detector during the 1992-1993 run. From a fit to the transverse mass spectrum, combined with measurements of the Z boson mass, the W boson mass is measured to be MW=80.350±0.140(stat)±0.165(syst)±0.160(scale) GeV/c 2 . Detailed discussions of the determination of the absolute energy scale, the measured efficiencies, and all systematic uncertainties are presented.

Abstract: We have searched for central production of a pair of photons with high transverse energies in $p\bar p$ collisions at $\sqrt{s} = 1.8$ TeV using $70 pb^{-1}$ of data collected with the D\O detector at the Fermilab Tevatron in 1994--1996. If they exist, virtual heavy pointlike Dirac monopoles could rescatter pairs of nearly real photons into this final state via a box diagram. We observe no excess of events above background, and set lower 95% C.L. limits of $610, 870, or 1580 GeV/c^2$ on the mass of a spin 0, 1/2, or 1 Dirac monopole., Comment: 12 pages, 4 figures

Abstract: The gauge boson pair production processes Wg, WW, WZ, and Zg were studied using pbarp collisions corresponding to an integrated luminosity of ~14 pb-1 at a center-of-mass energy of sqrt(s) = 1.8 TeV. Analysis of Wg prod with subsequent W boson decay to lv (l=e,mu) is reported, including a fit to the pT spectrum of the photons which leads to limits on anomalous WWg couplings. A search for WW prod with subsequent decay to l-lbar-v-vbar (l=e,mu) is presented leading to an upper limit on the WW prod cross section and limits on anomalous WWg and WWZ couplings. A search for high pT W bosons in WW and WZ prod is described, where one W boson decays to an ev and the second W boson or the Z boson decays to two jets. A maximum likelihood fit to the pT spectrum of W bosons resulted in limits on anomalous WWg and WWZ couplings. A combined fit to the three data sets which provided the tightest limits on anomalous WWg and WWZ couplings is also described. Limits on anomalous ZZg and Zgg couplings are presented from an analysis of the photon ET spectrum in Zg events in the decay channels (ee, mu-mu, and v-vbar) of the Z boson., 77 Pages including 40 Figures.

Abstract: We report on a search for pair production of a fourth generation charge -1/3 quark (b') in pbar p collisions at sqrt(s) = 1.8 TeV at the Fermilab Tevatron using an integrated luminosity of 93 pb^-1. Both quarks are assumed to decay via flavor changing neutral currents (FCNC). The search uses the signatures gamma + 3 jets + mu-tag and 2 gamma + 2 jets. We see no significant excess of events over the expected background. We place an upper limit on the production cross section times branching fraction that is well below theoretical expectations for a b' quark decaying exclusively via FCNC for b' quark masses up to m(Z) + m(b)., Eleven pages, two postscript figures, submitted to Physical Review Letters

Abstract: This study reports the first measurement of the azimuthal decorrelation between jets with pseudorapidity separation up to five units. The data were accumulated using the D{\O}detector during the 1992--1993 collider run of the Fermilab Tevatron at $\sqrt{s}=$ 1.8 TeV. These results are compared to next--to--leading order (NLO) QCD predictions and to two leading--log approximations (LLA) where the leading--log terms are resummed to all orders in $\alpha_{\scriptscriptstyle S}$. The final state jets as predicted by NLO QCD show less azimuthal decorrelation than the data. The parton showering LLA Monte Carlo {\small HERWIG} describes the data well; an analytical LLA prediction based on BFKL resummation shows more decorrelation than the data., Comment: 6 pages with 4 figures, all uuencoded and gzipped

Abstract: We present results on the search for the top quark in {ital p{bar p}} collisions at {radical}{ital s} =1.8 TeV with an integrated luminosity of 13.5{plus_minus}1.6 pb{sup {minus}1}. We have considered {ital t{bar t}} production in the standard model using electron and muon dilepton decay channels ({ital t{bar t}}{r_arrow}{ital e}{mu}+jets, {ital ee}+jets, and {mu}{mu}+jets) and single-lepton decay channels ({ital t{bar t}}{r_arrow}{ital e}+jets and {mu}+jets) with and without tagging of {ital b} quark jets. An analysis of these data optimized for top quark masses below 140 GeV/{ital c}{sup 2} gives a lower top quark mass limit of 128 GeV/{ital c}{sup 2}. An analysis optimized for higher top quark masses yields 9 events with an expected background of 3.8{plus_minus}0.9. If we assume that the excess is due to {ital t{bar t}} production, and assuming a top quark mass of 180 GeV/{ital c}{sup 2}, we obtain a cross section of 8.2{plus_minus}5.1 pb.

Abstract: The DO collaboration reports on a search for the Standard Model top quark in pbar-p collisions at Sqrt(s)=1.8TeV at the Fermilab Tevatron, with an integrated luminosity of approximately 50pb-1. We have searched for t-tbar production in the dilepton and single-lepton decay channels, with and without tagging of b-quark jets. We observed 17 events with an expected background of 3.8+/-0.6 events. The probability for an upward fluctuation of the background to produce the observed signal is 2.0E-6 (equivalent to 4.6 standard deviations). The kinematic properties of the excess events are consistent with top quark decay. We conclude that we have observed the top quark and measure its mass to be 199^+19_21 (stat.)+/- 22 (syst.)GeV/c**2 and its production cross section to be 6.4 +/- 2.2 pb., Comment: postscript available at http://fnnews.fnal.gov/top_paper_dzero.ps, for further info see http://fnnews.fnal.gov/top_discovery.html

Abstract: We present a measurement of tbar-t production using multijet final states in pbar-p collisions at a center-of-mass energy of 1.8 TeV, with an integrated luminosity of 110.3 pb(-1). The analysis has been optimized using neural networks to achieve the smallest expected fractional uncertainty on the tbar-t production cross section, and yields a cross section of 7.1 +/- 2.8(stat.) +/- 1.5(syst.) pb, assuming a top quark mass of 172.1 GeV/c^(2). Combining this result with previous D0 measurements, where one or both of the W bosons decay leptonically, gives a tbar-t production cross section of 5.9 +/- 1.2(stat) +/- 1.1(syst) pb., 6 pages, 3 figures; no substative change in revision

Abstract: We determine the top quark mass m{sub t} using t{bar t} pairs produced in the DO/ detector by {radical} (s) =1.8thinspTeV p{bar p} collisions in a 125thinsppb{sup {minus}1} exposure at the Fermilab Tevatron. We make a two constraint fit to m{sub t} in t{bar t}{r_arrow}bW{sup +}{bar b}W{sup {minus}} final states with one {ital W} boson decaying to q{bar q} and the other to e{nu} or {mu}{nu}. Likelihood fits to the data yield m{sub t}(l+jets)=173.3{plus_minus}5.6thinsp(stat)thinsp{plus_minus}thinsp5.5thinsp(s st) GeV/c{sup 2}. When this result is combined with an analysis of events in which both {ital W} bosons decay into leptons, we obtain m{sub t}=172.1{plus_minus}5.2thinsp(stat)thinsp{plus_minus}thinsp4.9thinsp(syst) GeV/c{sup 2}. An alternate analysis, using three constraint fits to fixed top quark masses, gives m{sub t}(l+jets)=176.0{plus_minus}7.9thinsp(stat){plus_minus}thinsp4.8thinsp(syst) GeV/c{sup 2}, consistent with the above result. Studies of kinematic distributions of the top quark candidates are also presented. {copyright} {ital 1998} {ital The American Physical Society}

Abstract: We have searched for a heavy neutral gauge boson, Z ′, using the decay channel Z ′ → ee . The data were collected with the DO detector at the Fermilab Tevatron during the 1992–1993 p p collider run at s =1.8 TeV from an integrated luminosity of 15±1 pb −1 . Limits are set on the cross section times brancing ratio for the process p p → Z′ → ee as a function of the Z ′ mass. We exclude the existence of a Z ′ of mass less than 490 GeV/c 2 , assuming a Z ′ with the same coupling strengths to quarks and leptons as the standard model Z boson.
