Abstract: Using data corresponding to an integrated luminosity of 79 pb-1, D0 has searched for events containing multiple jets and large missing transverse energy in pbar-p collisions at sqrt(s)=1.8 TeV at the Fermilab Tevatron collider. Observing no significant excess beyond what is expected from the standard model, we set limits on the masses of squarks and gluinos and on the model parameters m_0 and m_1/2, in the framework of the minimal low-energy supergravity models of supersymmetry. For tan(beta) = 2 and A_0 = 0, with mu < 0, we exclude all models with m_squark < 250 GeV/c^2. For models with equal squark and gluino masses, we exclude m < 260 GeV/c^2., 10 pages, 3 figures, Submitted to PRL, Fixed typo on page bottom of p. 6 (QCD multijet background is 35.4 events)

Abstract: We report a search for effects of large extra spatial dimensions in ppbar collisions at a center-of-mass energy of 1.8 TeV with the DZero detector, using events containing a pair of electrons or photons. The data are in good agreement with the expected background and do not exhibit evidence for large extra dimensions. We set the most restrictive lower limits to date, at the 95% confidence level, on the effective Planck scale between 1.0 TeV and 1.4 TeV for several formalisms and numbers of extra dimensions., Comment: 6 pages, 2 figures, submitted to Phys.

Abstract: We apply a quasi-model-independent strategy ("Sleuth") to search for new high p_T physics in approximately 100 pb^-1 of ppbar collisions at sqrt(s) = 1.8 TeV collected by the DZero experiment during 1992-1996 at the Fermilab Tevatron. We systematically analyze many exclusive final states and demonstrate sensitivity to a variety of models predicting new phenomena at the electroweak scale. No evidence of new high p_T physics is observed.

Abstract: We report on a study of the ratio of inclusive three-jet to inclusive two-jet production cross sections as a function of total transverse energy in p (p) over bar collisions at it center-of-mass energy roots = 1.8 TeV, using data collected with the DO detector during the 1992-1993 run of the Fermilab Tevatron Collider. The measurements are used to deduce preferred renormalization scales in perturbative O(alpha (3)(s)) QCD calculations in modeling soft-jet emission.

Abstract: We report a new measurement of the pseudorapidity (eta) and transverse-energy (Et) dependence of the inclusive jet production cross section in pbar b collisions at sqrt(s) = 1.8 TeV using 95 pb**-1 of data collected with the DZero detector at the Fermilab Tevatron. The differential cross section d^2sigma/dEt deta is presented up to |eta| = 3, significantly extending previous measurements. The results are in good overall agreement with next-to-leading order predictions from QCD and indicate a preference for certain parton distribution functions.

Abstract: The D0 collaboration has performed a study of spin correlation in tt-bar production for the process tt-bar to bb-bar W^+W^-, where the W bosons decay to e-nu or mu-nu. A sample of six events was collected during an exposure of the D0 detector to an integrated luminosity of approximately 125 pb^-1 of sqrt{s}=1.8 TeV pp-bar collisions. The standard model (SM) predicts that the short lifetime of the top quark ensures the transmission of any spin information at production to the tt-bar decay products. The degree of spin correlation is characterized by a correlation coefficient k. We find that k>-0.25 at the 68% confidence level, in agreement with the SM prediction of k=0.88.

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 report on a search for second generation leptoquarks (LQ) produced in p (p) over bar collisions at root s = 1.8 TeV using the DO detector at Fermilab. Second generation leptoquarks are assumed to be produced in pairs and to decay to either mu. or nu and either a strange or a charm quark (q). Limits an placed on sigma(p (p) over bar --> LQ --> mu nu + jets) as a function of the mass of the leptoquark. For equal branching ratios to mu q and nu q, second generation scalar leptoquarks with a mass below 160 GeV/c(2), vector leptoquarks with anomalous minimal vector couplings with a mass below 240 GeV/c(2), and vector leptoquarks with Yang-Mills couplings with a mass below 290 GeV/c(2), are excluded at the 95% confidence level.

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: We report on a search for $\mathrm{charge}\ensuremath{-}1/3$ third-generation leptoquarks (LQ) produced in $p\overline{p}$ collisions at $\ensuremath{\surd}s\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8\mathrm{TeV}$ using the $\mathrm{D}0$ detector at Fermilab. Third-generation leptoquarks are assumed to be produced in pairs and to decay to a tau neutrino and a $b$ quark with branching fraction $B$. We place upper limits on $\ensuremath{\sigma}(p\overline{p}\ensuremath{\rightarrow}\mathrm{LQ}\overline{\mathrm{LQ}}){B}^{2}$ as a function of the leptoquark mass ${M}_{\mathrm{LQ}}$. Assuming $B\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1$, we exclude at the 95% confidence level third-generation scalar leptoquarks with ${M}_{\mathrm{LQ}}l94\mathrm{GeV}{/c}^{2}$, and third-generation vector leptoquarks with ${M}_{\mathrm{LQ}}l216\mathrm{GeV}{/c}^{2}({M}_{\mathrm{LQ}}l148\mathrm{GeV}{/c}^{2}$) assuming Yang-Mills (anomalous) coupling.

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: We have measured the $\mathrm{WW}\ensuremath{\gamma}$ gauge boson coupling parameters using $p\overline{p}\ensuremath{\rightarrow}\ensuremath{\ell}\ensuremath{\nu}\ensuremath{\gamma}+X$ ( $\ensuremath{\ell}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}e,\ensuremath{\mu}$) events at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8$ TeV. The data, corresponding to an integrated luminosity of $92.8{\mathrm{pb}}^{\ensuremath{-}1}$, were collected using the D\O{} detector at the Fermilab Tevatron Collider. The measured cross section times branching ratio for $p\overline{p}\ensuremath{\rightarrow}W\ensuremath{\gamma}+X$ with ${p}_{T}^{\ensuremath{\gamma}}g10$ GeV/c and ${R}_{\ensuremath{\ell}\ensuremath{\gamma}}g0.7$ is ${11.3}_{\ensuremath{-}1.5}^{+1.7}\ifmmode\pm\else\textpm\fi{}1.5$ pb, in agreement with the standard model prediction. The 1 degree of freedom 95% confidence level limits on individual CP-conserving parameters are $\ensuremath{-}0.93l\ensuremath{\Delta}\ensuremath{\kappa}l0.94$ and $\ensuremath{-}0.31l\ensuremath{\lambda}l0.29$. Similar limits are set on the CP-violating coupling parameters.

Abstract: A search for new physics has been carried out in the channel pp→γγ+E T , as expected in various supersymmetric models. We require two photons with transverse energy E T γ >12GeV and pseudorapidity |η γ | T ) is consistent with background and no events have E T >25GeV. We set limits on production cross sections for selectron, sneutrino, and neutralino pairs, decaying into photons, which range from about 400 fb to 1 pb depending on the sparticle masses. A general limit of 185 fb (95% C.L.) is set on σ(pp→γγE T +X), where E T γ >12GeV, |η γ | T >25GeV.

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 present results from a search for anomalous $\mathrm{WW}$ and $\mathrm{WZ}$ production in $p\overline{p}$ collisions at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8\phantom{\rule{0ex}{0ex}}\mathrm{TeV}$. We used $p\overline{p}\ensuremath{\rightarrow}e\ensuremath{\nu}\mathrm{jjX}$ events observed during the 1992--1993 run of the Fermilab Tevatron collider, corresponding to an integrated luminosity of $13.7\ifmmode\pm\else\textpm\fi{}0.7{\mathrm{pb}}^{\ensuremath{-}1}$. A fit to the transverse momentum spectrum of the $W$ boson yields direct limits on the CP-conserving anomalous $\mathrm{WW}\ensuremath{\gamma}$ and $\mathrm{WWZ}$ coupling parameters of $\ensuremath{-}0.9l\ensuremath{\Delta}\ensuremath{\kappa}l1.1$ (with $\ensuremath{\lambda}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0$) and $\ensuremath{-}0.6l\ensuremath{\lambda}l0.7$ (with $\ensuremath{\Delta}\ensuremath{\kappa}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0$) at the 95% confidence level, for a form factor scale $\ensuremath{\Lambda}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.5\phantom{\rule{0ex}{0ex}}\mathrm{TeV}$, assuming that the $\mathrm{WW}\ensuremath{\gamma}$ and $\mathrm{WWZ}$ coupling parameters are equal.

Abstract: The global topologies of inclusive three- and four-jet events produced in $\overline{p}p$ interactions are described. The three- and four-jet events are selected from data recorded by the D0 detector at the Fermilab Tevatron Collider operating at a center-of-mass energy of $\sqrt{s}=1800$ GeV. The measured, normalized distributions of various topological variables are compared with parton-level predictions of tree-level QCD calculations. The parton-level QCD calculations are found to be in good agreement with the data. The studies also show that the topological distributions of the different subprocesses involving different numbers of quarks are very similar and reproduce the measured distributions well. The parton-shower Monte Carlo generators provide a less satisfactory description of the topologies of the three- and four-jet events.

Abstract: We have searched for associated production of the lightest chargino W 1 and next-to-lightest neutralino Z 2 of the minimal supersymmetric standard model in pp collisions at √s=1.8 TeV using the D0 detector at the Fermilab Tevatron collider. Data corresponding to an integrated luminosity of 12.5±0.7pb -1 were examined for events containing three isolated leptons. No evidence for W 1 Z 2 pair production was found. Limits on s(W 1 Z 2 )B(W 1 →lνZ 1 )B(Z 2 →llZ 1 ) are presented.

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 . A W′ with the same couplings to quarks and leptons as the standard model W boson is excluded for mW′

Abstract: The inclusive cross sections times leptonic branching ratios for $W$ and $Z$ boson production in $p\overline{p}$ collisions at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8$ TeV were measured using the D0 detector at the Fermilab Tevatron collider: ${\ensuremath{\sigma}}_{W}B(W\ensuremath{\rightarrow}e\ensuremath{\nu})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}2.36\ifmmode\pm\else\textpm\fi{}0.07\ifmmode\pm\else\textpm\fi{}0.13\mathrm{nb}$, ${\ensuremath{\sigma}}_{W}B\left(W\ensuremath{\rightarrow}\ensuremath{\mu}\ensuremath{\nu}\right)\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}2.09\ifmmode\pm\else\textpm\fi{}0.23\ifmmode\pm\else\textpm\fi{}0.11\mathrm{nb}$, ${\ensuremath{\sigma}}_{Z}B\left(Z\ensuremath{\rightarrow}{e}^{+}{e}^{\ensuremath{-}}\right)\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.218\ifmmode\pm\else\textpm\fi{}0.011\ifmmode\pm\else\textpm\fi{}0.012\mathrm{nb}$, and ${\ensuremath{\sigma}}_{Z}B\left(Z\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}\right)\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.178\ifmmode\pm\else\textpm\fi{}0.030\ifmmode\pm\else\textpm\fi{}0.009\mathrm{nb}$. The first error is the combined statistical and systematic uncertainty, and the second reflects the uncertainty in the luminosity. For the combined electron and muon analyses we find ${\ensuremath{\sigma}}_{W}B(W\ensuremath{\rightarrow}l\ensuremath{\nu})/{\ensuremath{\sigma}}_{Z}B(Z\ensuremath{\rightarrow}{l}^{+}{l}^{\ensuremath{-}})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}10.90\ifmmode\pm\else\textpm\fi{}0.49$. Assuming standard model couplings, this result is used to determine the width of the $W$ boson, $\ensuremath{\gamma}(W)\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}2.044\ifmmode\pm\else\textpm\fi{}0.093\mathrm{GeV}$.

Abstract: We performed a direct search for the anomalous {ital ZZ}{gamma} and {ital Z}{gamma}{gamma} couplings by studying {ital p{bar p}}{r_arrow}ll{gamma}+{ital X} (l={ital e},{mu}) events at {radical}{ital s}=1.8 TeV with the D0 detector at the Fermilab Tevatron Collider. A fit to the transverse energy spectrum of the photon in the signal events, based on the data set corresponding to an integrated luminosity of 14.3pb{sup {minus}1} (13.7pb{sup {minus}1}) for the electron (muon) channel, yields the following 95% confidence level limits on the anomalous {ital CP}-conserving {ital ZZ}{gamma} couplings: {vert_bar}{ital h}{sub 30}{sup {ital Z}}{vert_bar}{lt}1.8 ({ital h}{sub 40}{sup {ital Z}}=0) and {vert_bar}{ital h}{sub 40}{sup {ital Z}}{vert_bar}{lt}0.5 ({ital h}{sub 30}{sup {ital Z}}=0), for a form-factor scale {Lambda}=500 GeV. Limits for the {ital Z}{gamma}{gamma} couplings and {ital CP}-violating couplings are also discussed.

Abstract: The {ital WW}{gamma} gauge boson couplings were measured using {ital p{bar p}}{r_arrow}l{nu}{gamma}+{ital X} (l={ital e},{mu}) events at {radical}{ital s}=1.8 TeV observed with the D0 detector at the Fermilab Tevatron Collider. The signal, obtained from the data corresponding to an integrated luminosity of 13.8pb{sup {minus}1}, agrees well with the standard model prediction. A fit to the photon transverse energy spectrum yields limits at the 95% confidence level on the {ital CP}-conserving anomalous coupling parameters of {minus}1.6{lt}{Delta}{kappa}{lt}1.8 ({lambda}=0) and {minus}0.6{lt}{lambda}{lt}0.6 ({Delta}{kappa}=0). Similar limits are obtained for the {ital CP}-violating coupling parameters.

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 present a search for events consistent with the production and decay of the squarks and gluinos of the minimal supersymmetric standard model (MSSM) in the D0 detector at the Fermilab Tevatron {ital p{bar p}} collider. We examined data for events containing large missing transverse energy and three or more jets. We observed no excess of events above the expected yield from standard model processes. For a choice of MSSM parameter values, we set a lower limit at the 95% confidence level on the mass of the gluino of 144 GeV/{ital c}{sup 2} for all squark masses and a lower limit of 212 GeV/{ital c}{sup 2} for equal squark and gluino masses.

Abstract: We present a measurement of the inclusive jet cross section in {ital {bar p}p} collisions at {radical}{ital s} =1.8 TeV at the Fermilab Tevatron using the Collider Detector at Fermilab. Good agreement is seen with the predictions of recent next-to-leading-order ({ital O}({alpha}{sub {ital s}}{sup 3})) QCD predictions. The dependence of the cross section on clustering cone size is reported for the first time. An improved limit on {Lambda}{sub {ital c}}, a term characterizing possible quark substructure, is set at 1.4 TeV (95% C.L.).

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: 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: 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 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: 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: 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.
