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.

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.

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.

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.

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.

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 .

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.

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.

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.

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}.

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.

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′

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, $\ensuremath{\gamma}(W)\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}2.044\ifmmode\pm\else\textpm\fi{}0.093\mathrm{GeV}$.

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.

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.

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.

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.

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.

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.

First experimental results are presented from a search for events with a rapidity gap between jets. The D0 detector was used to examine events produced by the Fermilab Tevatron [ital p[bar p]] collider at [radical][ital s] =1.8 TeV. The fraction of events with an observed rapidity gap between the two highest transverse energy ([ital E][sub [ital T]]) jets is measured as a function of the pseudorapidity separation between the jet edges ([Delta][eta][sub [ital c]]). An upper limit at the 95% confidence level of 1.1[times]10[sup [minus]2] is obtained on the fraction of events with non particles between the jets, for events with [Delta][eta][sub [ital c]][gt]3 and jet [ital E][sub [ital T]] greater than 30 GeV.

We have searched for evidence of top quark production in pp\ifmmode\bar\else\textasciimacron\fi{} collisions at \ensuremath{\surd}s =1.8 TeV using the D0 detector at the Fermilab Tevatron collider. For an integrated luminosity of 15 ${\mathrm{pb}}^{\mathrm{\ensuremath{-}}1}$, we report results of a search for tt\ifmmode\bar\else\textasciimacron\fi{} pairs in the decay modes tt\ifmmode\bar\else\textasciimacron\fi{}\ensuremath{\rightarrow}e\ensuremath{\mu}+jets,ee+jets,e+jets, and \ensuremath{\mu}+jets. From analyses of these modes we obtain a lower limit on the top quark mass of 131 GeV/${\mathit{c}}^{2}$ at the 95% confidence level, assuming standard model branching fractions and a predicted cross section for tt\ifmmode\bar\else\textasciimacron\fi{} production. We discuss the properties of an event for which expected backgrounds are small.

As part of the calibration procedure, these modules were exposed to beams of electrons, pions and muons between 10 and 150 GeV/c before their installation in the end calorimeter of the completed DO detector. We obtain an electromagnetic sampling resolution of 15.7%/√E and constant term of 0.3%. The hadronic sampling resolution is 45%/√E (degraded to 50%/√E by the effects of upstream material) and the constant term is 4%. The calorimeter is linear to 0.5%, and the electromagnetic to hadronic response ratio is between 1.02 and 1.09 over this range of momenta. For an electron efficiency of 95% we obtain a rejection factor against pions of ∼ 900-3000 for particles in the momentum range between 50 and 150 GeV/c. We also compare our results with the predictions of a detailed Monte Carlo simulation.

To protect against replay attacks, many Internet protocols rely on nonces to guarantee freshness. In practice, the server generates these nonces during the initial handshake, but if the server is under attack, resources consumed by managing certain protocols can lead to DoS vulnerabilities. To help alleviate this problem, we propose the concept of rhythmic nonces, a cryptographic tool that allows servers to measure request freshness with minimal bookkeeping costs. We explore the impact of this service in the context of a puzzle-based DoS resistance scheme we call "SYN puzzles". Our preliminary results based on mathematical analysis and evaluation of a prototype suggests that our scheme is more resistant than existing techniques.

An evolutionary approach proposed in [1, 2] combining the achievements of traditional macroscopic theory of solid mechanics and basic ideas of nonlinear dynamics is applied in a numerical simulation of present-day tectonic plates motion and seismic process in Central Asia. Relative values of strength parameters of rigid blocks with respect to the soft zones were characterized by the δ parameter that was varied in the numerical experiments within δ = 1.1-1.8 for different groups of the zonal-block divisibility. In general, the numerical simulations of tectonic block motion and accompanying seismic process in the model geomedium indicate that the numerical solutions of the solid mechanics equations characterize its deformation as a typical behavior of a nonlinear dynamic system under conditions of self-organized criticality.

Evolution of the stress-strain state in the rock mass with excavation is studied numerically. The nonequilibrium state of the rock mass and the conditions of its critical states, which result in catastrophic collapses, are investigated. It is shown that the features of a flicker (1/f) noise indicating multiple fracture in the roof and floor suggest proximity of the critical state. [ABSTRACT FROM AUTHOR]

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| < 0.9 and 1.6 < |η| < 2.5. The data represent 12.9 pb-1 of integrated luminosity accumulated in p̄p collisions at √s = 1.8 TeV and recorded with the DO 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 ≲ ET y ≲ 80 GeV.

High Energy Physics::Phenomenology ,High Energy Physics::Experiment - Abstract
We present results from a search for anomalous WW and WZ production in p p̄ collisions at √s = 1.8 TeV. We used p p̄ →jjX events observed during the 1992-1993 run of the Fermilab Tevatron collider. corresponding to an integrated luminosity of 13.7 ± 0.7 pb -1. A fit to the transverse momentum spectrum of the W boson yields direct limits on the CP-conserving anomalous WWγ and WWZ coupling parameters of -0.9 < Δκ < 1.1 (with λ = 0) and -0.6 < λ < 0.7 (with Δκ = 0) at the 95% confidence level, for a form factor scale Λ = 1.5 TeV, assuming that the WWγ and WWZ coupling parameters are equal.

High Energy Physics::Phenomenology ,High Energy Physics::Experiment - Abstract
The global topologies of inclusive three- and four-jet events produced in p̄p interactions are described. The three- and four-jet events are selected from data recorded by the DO detector at the Fermilab Tevatron Collider operating at a center-of-mass energy of √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. © 1996 The American Physical Society.

High Energy Physics::Experiment - Abstract
We report on a search for right-handed W bosons (WR) with mass greater than 200 GeV/c2. We used data collected with the DO detector at the Fermilab Tevatron p p̄ collider at √s = 1.8 TeV to search for WR decays into an electron and a massive right-handed neutrino WR +- → e+-NR. Using the inclusive electron data, we set mass limits independent of the NR decay: mWR > 650 GeV/c2 and mWR > 720 GeV/c2 at the 95% confidence level, valid for mNR > 1/2mWR and mNR ≪ mWR. 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 mWRvalid for larger values of the NR mass are obtained assuming that NR decays to an electron and two jets.

- Abstract
We have searched for associated production of the lightest chargino W̃1 and next-to-lightest neutralino Z̄2 of the minimal supersymmetric standard model in pp̄ collisions at √s = 1.8 TeV using the DO detector at the Fermilab Tevatron collider. Data corresponding to an integrated luminosity of 12.5 ± 0.7 pb-1 were examined for events containing three isolated leptons. No evidence for W̃1Z̃2 pair production was found. Limits on σ(W̃1Z̃2)B(W̃1 → lνZ̃1)B(Z̃2 → ll̄Z̃1) are presented.

High Energy Physics::Phenomenology ,High Energy Physics::Experiment - 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 pp̄ collider. We consider a scenario in which the lighter of the two top squarks t̃ l decays with 100% branching fraction to a charm quark and the lightest neutralino X̃ 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 mt̃1-mX̃10 parameter space. The highest mt̃1 value we exclude is 93 GeV/c 2 with a corresponding mmX̃10 value of 8 GeV/c 2.

High Energy Physics::Phenomenology ,High Energy Physics::Experiment - Abstract
A study of the particle multiplicity between jets with large rapidity separation has been performed using the D0 detector at the Fermilab Tevatron pp̄ Collider operating at √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 ± 0.10(stat) -0.13 +0.25(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.
