Abstract: The KLOE detector was designed primarily For the study of CP violation in neutral kaon decays at DAPhiNE, the Frascati Phi-factory. The detector consists of a tracker and an electromagnetic calorimeter. A lead-scintillating-fiber sampling calorimeter satisfies best the requirements of the experiment. providing adequate energy resolution and superior timing accuracy. We describe in the following the construction of the calorimeter, its calibration and how the calorimeter information is used to obtain energy, point of entry and time of the arrival of photons, electrons and charged particles. With e(+)e(-) collision data at DAPhiNE for an integrated luminosity of some 2 pb(-1) we find for electromagnetic showers, an energy resolution of 5.7%/rootE(GeV) and a time resolution of 54/rootE(GeV) ps. We also present a measurement of efficiency for low energy photons. (C) 2002 Elsevier Science B.V. All rights reserved.

Abstract: We have measured the ratio R-S(pi) = Gamma(K-S --> pi(+)pi(-)(gamma))/Gamma(K-S --> pi(0)pi(0)) with the KLOE detector at the DAPhiNE e(+)e(-) collider. This measurement is fully inclusive with respect to the pi(+)pi(-)gamma final state. The sample of over 106 two-pion decays of tagged K-S mesons allows a statistical error as low as similar to 0.1% to be obtained. The accuracy is limited by systematic uncertainties, which are estimated primarily from data. We find R-S(pi) = 2.236 +/- 0.003(stat) +/- 0.015(syst).

Abstract: We have measured the cross section $\sigma(e^+e^-\to\pi^+\pi^-\gamma)$ with the KLOE detector at DA$\Phi$NE, at an energy $W=M_\phi=1.02$ GeV. From the dependence of the cross section on $m(\pi^+\pi^-)=\sqrt{W^2-2WE_\gamma}$, where $E_\gamma$ is the energy of the photon radiated from the initial state, we extract $\sigma(e^+e^-\to\pi^+\pi^-)$ for the mass range $0.35

Abstract: We report on measurements of the $\ensuremath{\Upsilon}(1S)$, $\ensuremath{\Upsilon}(2S)$, and $\ensuremath{\Upsilon}(3S)$ differential, ${(\frac{{d}^{2}\ensuremath{\sigma}}{d{P}_{t}\mathrm{dy}})}_{y=0}$, and integrated cross sections in $p\overline{p}$ collisions at $\sqrt{s}=1.8$ TeV using a sample of 16.6 \ifmmode\pm\else\textpm\fi{} 0.6 ${\mathrm{pb}}^{\ensuremath{-}1}$ collected by the Collider Detector at Fermilab. The three resonances were reconstructed through the decay $\ensuremath{\Upsilon}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$. Comparison is made to a leading order QCD prediction.

Abstract: We analyze a sample of {ital W}+jet events collected with the Collider Detector at Fermilab (CDF) in {ital pp} collisions at {radical}{ital s}=1.8 TeV to study {ital tt} production. We employ a simple kinematical variable H, defined as the scalar sum of the transverse energies of the lepton, neutrino, and jets. For events with a {ital W} boson and four or more jets, the shape of the H distribution deviates by 3.8 standard deviations from that expected from known backgrounds to {ital tt} production. However, this distribution agrees well with a linear combination of background and {ital tt} events, the agreement being best for a top mass of 180 GeV/{ital c}{sup 2}. {copyright} {ital 1995} {ital The} {ital American} {ital Physical} {ital Society}.

Abstract: The effects of flavonols on P-glycoprotein (Pgp) activity were studied in cultured rat hepatocytes by assessing and transmembrane transport of Rhodamine-123 (R-123) and doxorubicin (DOX). In freshly-plated hepatocytes, containing a low amount of Pgp, flavonols did not affect the cellular retention of DOX, but strongly inhibited the Pgp-mediated efflux of R-123. In 72h-cultured hepatocytes, spontaneously overexpressing functional Pgp, flavonols inhibited R-123 efflux in a dose-dependent manner, but significantly reduced DOX retention while increasing its efflux. A similar effect was found in hepatocytes obtained from rats in which Pgp was induced in vivo by 2-acetamino-fluorene (AAF) or alpha-naphthyl-isothiocyanate (ANIT) treatments. These findings indicate that flavonols, dietary compounds reported to strongly upregulate the apparent activity of Pgp in cancer cell lines, may also modulate differently the transport of putative Pgp substrates in normal rat hepatocytes. The ability to affect the drug-extruding activity at the hepatocyte canalicular membrane could be of relevance to the chemopreventive action of these compounds towards liver carcinogens.

Abstract: This paper presents the first direct measurement of the $B$ meson differential cross section $d\ensuremath{\sigma}{/dp}_{T}$ in $p\overline{p}$ collisions at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8$ TeV using a sample of $19.3\ifmmode\pm\else\textpm\fi{}0.7$ p${\mathrm{b}}^{--1}$ accumulated by the Collider Detector at Fermilab. The cross section is measured in the central rapidity region $|y|l1$ for ${p}_{T}\left(B\right)g6.0$ GeV $/c$ by fully reconstructing the $B$ meson decays ${B}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}{K}^{+}$ and ${B}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}{K}^{*0}\left(892\right)$, where $J/\ensuremath{\psi}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ and ${K}^{*0}\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$. A comparison is made to the theoretical QCD prediction calculated at next-to-leading order.

Abstract: We present the results of a search for second generation leptoquarks ${S}_{2}$ using $19.3{\mathrm{pb}}^{\ensuremath{-}1}$ of data collected at the Collider Detector at Fermilab (CDF) in $p\overline{p}$ collisions at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8$ TeV during the 1992--93 collider run. We have searched for ${S}_{2}\overline{{S}_{2}}$ pairs assuming that each leptoquark decays to a muon $+$ quark with a branching ratio $\ensuremath{\beta}$. We find two candidate events, consistent with an expected background of $1.11\ifmmode\pm\else\textpm\fi{}0.48$. We obtain upper limits on $\ensuremath{\sigma}(p\overline{p}\ensuremath{\rightarrow}{S}_{2}\overline{{S}_{2}}){\ensuremath{\beta}}^{2}$ as a function of ${M}_{{S}_{2}}$. Using a Monte Carlo prediction for ${S}_{2}\overline{{S}_{2}}$ pair production, we exclude ${M}_{{S}_{2}}l131\phantom{\rule{0ex}{0ex}}\mathrm{GeV}/{c}^{2}$ for $\ensuremath{\beta}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1$ and ${M}_{{S}_{2}}l96\phantom{\rule{0ex}{0ex}}\mathrm{GeV}/{c}^{2}$ for $\ensuremath{\beta}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.5$ at 95% C.L.

Abstract: We have sought evidence for radiative decays of neutralinos produced in proton-antiproton collisions at {radical}{ital s}=1.8TeV. Events containing two photons plus large missing transverse energy were investigated. The observed event rate and the missing transverse energy distribution of the two-photon events are consistent with QCD predictions. Inferred limits on squark and gluino masses depend on the supersymmetry model parameters. The particular choices {mu}={minus}40GeV/{ital c}{sup 2} and tan{beta}=1.5 lead to 90%-confidence-level asymptotic lower limits of 110 GeV/{ital c}{sup 2} and 140 GeV/{ital c}{sup 2} for squarks and gluinos, respectively.

Abstract: We have searched for new, heavy, charged bosons {ital W}{prime} through the decay {ital W}{prime}{r_arrow}{ital e}{nu} in {ital pp}{ovr bar} collisions at {radical}{ital s}=1.8 TeV. The data used in the search represent 19.7 pb{sup --1}collected by the Collider Detector at Fermilab. Limits are placed on {sigma}{ital B}({ital pp}{ovr bar}{r_arrow}{ital W}{prime}{r_arrow}{ital e}{nu}) as a function of {ital M}{sub {ital W}{prime}}. Assuming standard couplings of the {ital W}{prime} to fermions, we establish the limit {ital M}{sub {ital W}{prime}}{gt}652 GeV/{ital c}{sup 2} (95% C.L.).

Abstract: We establish the existence of the top quark using a $67{\mathrm{pb}}^{\ensuremath{-}1}$ data sample of $\overline{p}p$ collisions at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8\mathrm{TeV}$ collected with the Collider Detector at Fermilab (CDF). Employing techniques similar to those we previously published, we observe a signal consistent with $t\overline{t}$ decay to $\mathrm{WWb}\overline{b}$, but inconsistent with the background prediction by $4.8\ensuremath{\sigma}$. Additional evidence for the top quark is provided by a peak in the reconstructed mass distribution. We measure the top quark mass to be $176\ifmmode\pm\else\textpm\fi{}8(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}10(\mathrm{syst})\mathrm{GeV}{/c}^{2}$, and the $t\overline{t}$ production cross section to be ${6.8}_{\ensuremath{-}2.4}^{+3.6}\mathrm{pb}$.

Abstract: Charge asymmetry has been measured using 19 039 [ital W] decays recorded by the Collider Detector at Fermilab during the 1992--93 run of the Tevatron Collider. The asymmetry is sensitive to the ratio of [ital d] and [ital u] quark distributions to [ital x][lt]0.01 at [ital Q][sup 2][approx][ital M][sup 2][sub [ital W]], where nonperturbative effects are minimal. It is found that of the two current sets of parton distributions, those of Martin, Roberts, and Stirling are favored over the sets most recently produced by the CTEQ Collaboration. The [ital W] asymmetry data provide stronger constraints on [ital d]/[ital u] ratio than the recent measurements of [ital F][sub 2][sup [mu][ital n]]/[ital F][sub 2][sup [mu][ital p]], which are limited by uncertainties originating from deuteron corrections.

Abstract: In $p\overline{p}$ collisions at $\sqrt{s}=1.8$ TeV we find jet events with a rapidity gap topology. The number of hadrons in the rapidity interval $\ensuremath{\Delta}{\ensuremath{\eta}}_{D}$ between leading-jet cones was sampled by charged tracks with ${P}_{T}g400$ MeV/c. We find excess trackless events beyond that expected in a smooth multiplicity distribution. In a control region outside $\ensuremath{\Delta}{\ensuremath{\eta}}_{D}$ we see no excess. For $\ensuremath{\Delta}{\ensuremath{\eta}}_{D}g0.8$, the fraction of excess trackless events, consistent with estimates based on exchange of color-singlet digluons, is $R(\mathrm{gap})=\frac{{\ensuremath{\sigma}}_{\mathrm{jet}}(\mathrm{gap})}{{\ensuremath{\sigma}}_{\mathrm{jet}}}=0.0085\ifmmode\pm\else\textpm\fi{}{0.0012(\mathrm{stat})}_{\ensuremath{-}0.0012}^{+0.0024}(\mathrm{syst})$.

Abstract: The main aim of the KLOE experiment at DA Phi NE, the Frascati phi -factory, is to study CP violation in the K-0-(K) over bar (0) system. Requirements on shower detection are very stringent. An hermetic, lead-scintillating fiber sampling calorimeter has been chosen and built. A review of the methods used to calibrate and reconstruct energy and timing is reported in this paper. Emphasis is given to the calibration procedures developed using the 2.4 pb(-1) collected in 1999. An energy resolution of 5.7% rootE/GeV is achieved together with a linearity in energy response better than 1% above 50 MeV. A time resolution of similar to 54 ps/ rootE/GeV is also measured on samples of radiative Bhabha and Phi decays. (C) 2001 Elsevier Science B.V. Ail rights reserved.

Abstract: We present the results of a search in [ital [bar p]] [ital p] collisions at [radical][ital s] =1.8 TeV for the top quark decaying to a charged Higgs bosson ([ital H][sup [plus minus]]). We search for dilepton final states from the decay chain [ital t] [ital [bar t]][r arrow][ital HH] (or [ital HW], or [ital WW])+[ital b] [ital [bar b]][r arrow][ital ll]+[ital X]. In a sample of 19.3 pb[sup [minus]1] collected during 1992--93 with the Collider Detector at Fermilab, we observe 2 events with a background estimation of 3.0[plus minus]1.0 events. Limits at 95% C.L. in the (M[sub top],M[sub [ital H][sup [plus minus]]]) plane are presented. For the case [ital M][sub top][lt][ital M][sub [ital W]]+[ital M][sub [ital b]], we exclude at 95% C.L. the entire ([ital M][sub top],[ital M][sub H[plus minus]]) plane for the branching ratio [ital B]([ital H][r arrow][tau][nu]) larger than 75%. We also interpret the results in terms of the parameter tan[beta] of two-Higgs-doublet models.

Abstract: Color coherence effects in pp\ifmmode\bar\else\textasciimacron\fi{} collisions are observed and studied with CDF, the Collider Detector at the Fermilab Tevatron collider. We demonstrate these effects by measuring spatial correlations between soft and leading jets in multijet events. Variables sensitive to interference are identified by comparing the data to the predictions of various shower Monte Carlo programs that are substantially different with respect to the implementation of coherence.

Abstract: The [ital W]+jet angular distribution is measured using [ital W][minus][gt][ital e][nu] events recorded with the Collider Detector at Fermilab (CDF) during 1988--89 and 1992--93 Tevatron runs. The data agree well with both a leading order and a next-to-leading order theoretical prediction. The shape of the angular distribution is similar to that observed in photon+jet data, and significantly different from that observed in dijet data.

Abstract: This paper reports the measurement of the [ital B] meson and [ital b] quark cross sections through the decay chain [ital B][sup 0][r arrow][ital J]/[psi] K[sup *](892)[sup 0], [ital J]/[psi][r arrow][mu][sup +][mu][sup [minus]], [ital K][sup *](892)[sup 0][r arrow][ital K][sup +][pi][sup [minus]], using 4.3 pb[sup [minus]1] of data collected at the Collider Detector at Fermilab in [ital [bar p]p] collisions at [ital qrts]=1.8 TeV. We obtain [sigma][sub [ital B]]=1.5[plus minus]0.7(stat)[plus minus]0.6(syst) [mu]b for [ital B][sup 0] mesons with transverse momentum [ital P][sub [ital T]][gt]9.0 GeV/[ital c] and rapidity [vert bar][ital y][vert bar][lt]1.0. Using this result, we find [sigma][sub [ital b]]=3.7[plus minus]1.6(stat)[plus minus]1.5(syst) [mu]b for [ital b] quarks with [ital P][sub [ital T]][gt]11.5 GeV/[ital c] and rapidity [vert bar][ital y][vert bar][lt]1.0. The [ital b] quark cross section is compared to next-to-leading order QCD calculations and previous measurements.

Abstract: The amount and activity of the multi-drug transporter P-glycoprotein (Pgp) have been measured in cultured hepatocytes derived from different rat strains. A marked increase in Pgp, as revealed by Western blotting, occurred 48 h after seeding in hepatocytes from Sprague-Dawley, Wistar and Fischer 344 rats, the last showing the highest value. The addition of dexamethasone (DEX) to culture medium delayed Pgp overexpression in all the strains, proportionally to the protein amount in the absence of hormone. The R-123 functional test for Pgp showed that Fischer 344 hepatocytes had the lowest ability to extrude the fluorescent dye as compared with Sprague-Dawley or Wistar rats. These results suggest that the Fischer 344 rat is more prone than other strains to culture stressing conditions, leading to an overexpression of Pgp that is not necessarily functional.

Abstract: We measure the Drell-Yan differential cross section [ital d][sup 2][sigma]/[ital dM] d[ital y][vert bar][sub [vert bar][ital y][vert bar][lt]1] over the mass range 11[lt][ital M][lt]150 GeV/[ital c][sup 2] using dielectron and dimuon data from [ital [bar p]p] collisions at a center-of-mass energy of [radical][ital s] =1.8 TeV. Our results show the 1/[ital M][sup 3] dependence that is expected from the naive Drell-Yan model. In comparison to the predictions of recent QCD calculations we find our data favor those parton distribution functions with the largest quark contributions in the [ital x] interval 0.006 to 0.03.

Abstract: The KLOE experiment's major physics goal is to measure the R( ϵ′ ϵ ) , with a precision of 10−4, via both the traditional double ratio method and the kaons' quantum interferometry. The experiment has started taking data at DAfNE, the f-factory at the Frascati National Laboratory (LNF) of INFN in Italy, beginning in April 1999. Integrated luminosity exceeding 100 pb−1 (108 f's) are expected to be delivered for end 1999/early 2000. A description of the detector's design and of its performances is presented. At the moment of writing the experiment has collected its first collisions for an integrated luminosity of 220 nb−1; the peak luminosity reached has been of 2 × 1030 cm−2sec−1.

Abstract: KLOE, a new state of the art detector recently commissioned for physics operation at DAFNE, has many innovative interesting features, especially in the DAQ and Trigger areas. Custom electronics assert a trigger in a 2 microseconds decision time and distributes it to the FEE with a 50 ps time resolution. Data are read out using 10 front-end data acquisition chains and sent to a farm of online servers through a FDDI Gigaswitch. This design of the KLOE DAQ system allows us to manage an input data rate as high as 50 Mbyte/s, and is completely scalable by extending the number of computers connected to the switch

Abstract: We present results of a search for a first-generation leptoquark [ital scrS][sub 1] in [ital [bar p]p] collisions at [radical][ital s] =1.8 TeV at the Fermilab Tevatron. Using 4.05 pb[sup [minus]1] of data collected during the 1988--1989 CDF run, we have searched for evidence of [ital scrS][sub 1][ital scr[bar S]1] production assuming that each leptoquark decays to an electron+quark pair with a branching ratio [beta]. Three events with two high energy electrons and two high energy jets were found, but are consistent with [ital Z][sup 0] decay. No events were found in the signal region. Assuming a short lived scalar leptoquark with Yukawa coupling strength [lambda][approx gt]2[times]10[sup [minus]7], we exclude [sigma][beta][sup 2][gt]55(4.0) pb at 95% C.L. for [ital M][sub [ital s][ital c][ital r][ital S]]=45(125) GeV/[ital c][sup 2]. Using a Monte Carlo prediction for [sigma]([ital [bar p]p][r arrow][ital scrS][sub 1][ital scr[bar S]1]+[ital X]), we exclude [ital M][sub [ital s][ital c][ital r][ital S]][lt]113(80) GeV/[ital c][sup 2] for [beta]=100(50)%.

This exclusive ${\mathrm{\ensuremath{\chi}}}_{\mathit{c}}$ sample is used to measure the ${\mathrm{\ensuremath{\chi}}}_{\mathit{c}}$-meson production cross section times branching fractions.

From this and the inclusive J/\ensuremath{\psi} cross section we calculate the inclusive b-quark cross section to be 12.0\ifmmode\pm\else\textpm\fi{}4.5 \ensuremath{\mu}b for ${\mathit{p}}_{\mathit{T}}^{\mathit{b}}$g8.5 GeV/c and \ensuremath{\Vert}${\mathit{y}}^{\mathit{b}}$\ensuremath{\Vert}1.

Abstract: The first prompt photon measurement from the CDF experiment at the Fermilab [ital p[bar p]] Collider is presented. Two independent methods are used to measure the cross section: one for high transverse momentum ([ital P][sub [ital T]]) and one for lower [ital P][sub [ital T]]. Comparisons to various theoretical calculations are shown. The cross section agrees qualitatively with QCD calculations but has a steeper slope at low [ital P][sub [ital T]].

Abstract: The dijet invariant mass distribution has been measured in the region between 120 and 1000 GeV/[ital c][sup 2], in 1.8-TeV [ital p[bar p]] collisions. The data sample was collected with the Collider Detector at Fermilab (CDF). Data are compared to leading order (LO) and next-to-leading order (NLO) QCD calculations using two different clustering cone radii [ital R] in the jet definition. A quantitative test shows good agreement of data with the LO and NLO QCD predictions for a cone of [ital R]=1. The test using a cone of [ital R]=0.7 shows less agreement. The NLO calculation shows an improvement compared to LO in reproducing the shape of the spectrum for both radii, and approximately predicts the cone size dependence of the cross section.

Abstract: Kinematic properties of four-jet events produced in $p\overline{p}$ collisions at $\sqrt{s}=1.8$ TeV have been studied using data with an integrated luminosity of 325 ${\mathrm{nb}}^{\ensuremath{-}1}$ collected using the Collider Detector at Fermilab during the 1988-1989 Fermilab Collider run. The individual jet ${p}_{T}$ spectra and the angles between each jet pair are compared to the predictions of leading-order quantum chromodynamics for the double gluon bremsstrahlung process and good agreement is observed. In addition, a search for double parton scattering has been undertaken using variables sensitive to the topology of four-jet events. A small double parton content provides the best description of the data. We find $\frac{{N}_{\mathrm{DP}}}{{N}_{\mathrm{DB}}}={5.4}_{\ensuremath{-}2.0}^{+1.6}%$, where $N$ represents the number of events attributed to each process. We measure ${\ensuremath{\sigma}}_{\mathrm{DP}}={63}_{\ensuremath{-}28}^{+32}$ nb for jets having ${p}_{T}g25$ GeV/c in the pseudorapidity interval $|\ensuremath{\eta}|l3.5$.

Abstract: We have searched for the $b$-flavored baryon decay ${\ensuremath{\Lambda}}_{b}\ensuremath{\rightarrow}\frac{J}{\ensuremath{\psi}}{\ensuremath{\Lambda}}^{0}$ in $p\overline{p}$ collisions at $\sqrt{s}=1.8$ TeV with the Collider Detector at Fermilab (CDF). In the $\frac{J}{\ensuremath{\psi}}{\ensuremath{\Lambda}}^{0}$ invariant-mass distribution we observe a flat distribution and a small number of events, consistent with no signal. Using the $b$-quark cross section measured by the CDF we put an upper limit on the $b\ensuremath{\rightarrow}{\ensuremath{\Lambda}}_{b}$ production fraction times the branching ratio $F({\ensuremath{\Lambda}}_{b})B({\ensuremath{\Lambda}}_{b}\ensuremath{\rightarrow}\frac{J}{\ensuremath{\psi}}{\ensuremath{\Lambda}}^{0})$ of 0.50\ifmmode\times\else\texttimes\fi{}${10}^{\ensuremath{-}3}$ at 90% confidence level.

Abstract: To test the activity of P-170 glycoprotein in isolated hepatocytes, a method has been developed employing the fluorescent dye rhodamine 123 (R-123). The uptake of R-123 by both freshly isolated and 4-hr-plated hepatocytes depends on dye concentration, time of incubation, and cell number. The efflux of R-123 from cells is inhibited by sodium azide and by verapamil. In standard conditions the efficiency of efflux of R-123 from cells correlates with the relative amount of immunoblottable glycoprotein. The method has been applied to detection of P-170 activity in hepatocytes from animals of different ages as well as from carcinogen-treated animals. The proposed assay appears a simple and adequate tool for the functional assessment of multidrug transporter in liver.

Abstract: We investigate different dissociation mechanisms for O2 gas during pulsed-laser ablation and deposition. Mesaurements are carried out by using an in situ diagnostics based on absorption spectroscopy of oxygen gas, with space- and time-resolved capabilities, during laser ablation of a metal alloy target in the presence of an oxygen environment. Data, analyzed as a function of ablation parameters, indicate that two different mechanisms, involving electron collisions and formation of a high-density, high-temperature shock layer, play an important role in producing atomic oxygen which can subsequently react with the ablated species.

Abstract: Inclusive [ital J]/[psi] and [psi](2[ital S]) production has been studied in [ital [bar p]p] collisions at [radical][ital s] =1.8 TeV using 2.6[plus minus]0.2 pb[sup [minus]1] of data taken with the Collider Detector at Fermilab. The products of production cross section times branching fraction were measured as functions of [ital P][sub [ital T]] for [ital J]/[psi][r arrow][mu][sup +][mu][sup [minus]] and [psi](2[ital S])[r arrow][mu][sup +][mu][sup [minus]]. In the kinematic range [ital P][sub [ital T]][gt]6 GeV/[ital c] and [vert bar][eta][vert bar][le]0.5 we get [sigma]([ital [bar p]p][r arrow][ital J]/[psi] [ital X])[ital B]([ital J]/[psi][r arrow][mu][sup +][mu][sup [minus]]) =6.88[plus minus]0.23(stat)[sub [minus]1.08][sup +0.93](syst) nb, and [sigma]([ital [bar p]p][r arrow][psi](2[ital S])[ital X])[ital B]([psi](2[ital S])[r arrow][mu][sup +][mu][sup [minus]]) =0.232[plus minus]0.051(stat)[sub [minus]0.032][sup +0.029](syst)nb.

At the 95% confidence level, we find an upper limit on the partial decay width to be \ensuremath{\Gamma}(${\mathit{W}}^{\ifmmode\pm\else\textpm\fi{}}$\ensuremath{\rightarrow}\ensuremath{\gamma}${\mathrm{\ensuremath{\pi}}}^{\ifmmode\pm\else\textpm\fi{}}$)/\ensuremath{\Gamma}(${\mathit{W}}^{\ifmmode\pm\else\textpm\fi{}}$\ensuremath{\rightarrow}${\mathit{e}}^{\ifmmode\pm\else\textpm\fi{}}$\ensuremath{\nu})\ensuremath{\le}7.5\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}3}$.

Abstract: We present results of searches for the top quark in {ital p{bar p}} collisions at {radical}{ital s} =1.8 TeV. The data sample was collected during 1988--1989 at the Fermilab Tevatron Collider and has an integrated luminosity of 4.1 pb{sup {minus}1}. We have extended our previous search for {ital e}{mu} final states to include the {ital ee} and {mu}{mu} channels. In addition, we have searched for a low-transverse-momentum muon as a tag of the bottom quark in top decay events with a lepton and at least two jets. We obtain a lower limit on the top-quark mass of 91 GeV/{ital c}{sup 2} at the 95% confidence level assuming standard-model charged-current decays.

Abstract: The production and event topology of three-jet events produced in {ital p{bar p}} collisions at {radical}{ital s} =1.8 TeV have been studied with the Collider Detector at Fermilab at the Tevatron Collider. The distributions of the three-jet angular variables ({psi}{sup *} and cos{theta}{sup *}) and of the variables describing the energy sharing between jets ({ital x}{sub 3} and {ital x}{sub 4}) are found to agree well with tree-level QCD calculations. These distributions are predicted to have different shapes for different initial-state subprocesses (quark-antiquark, quark-gluon, and gluon-gluon). The data are consistent with the small expected contribution from quark-antiquark initial states, in agreement with theoretical expectations.

Abstract: [1] Changes beneath a volcano can be observed through position changes in a GPS network, but distinguishing the source of site motion is not always straightforward. The records of continuous GPS sites provide a favorable data set for tracking magma migration. Dense campaign observations usually provide a better spatial picture of the overall deformation field, at the expense of an episodic temporal record. Combining these observations provides the best of both worlds. A Kalman filter provides a means for integrating discrete and continuous measurements and for interpreting subtle signals. The unscented Kalman filter (UKF) is a nonlinear method for time-dependent observations. We demonstrate the application of this technique to deformation data by applying it to GPS data collected at Okmok volcano. Seven years of GPS observations at Okmok are analyzed using a Mogi source model and the UKF. The deformation source at Okmok is relatively stable at 2.5 km depth below sea level, located beneath the center of the caldera, which means the surface deformation is caused by changes in the strength of the source. During the 7 years of GPS observations more than 0.5 m of uplift has occurred, a majority of that during the time period January 2003 to July 2004. The total volume recovery at Okmok since the last eruption in 1997 is ∼60–80%. The UKF allows us to solve simultaneously for the time-dependence of the source strength and for the location without a priori information about the source.

Abstract: The {ital W}{prime} is a charged, heavy, vector boson predicted to exist by some extensions of the standard model. We have searched for the processes {ital W}{prime}{r arrow}{ital e}{nu} and {ital W}{prime}{r arrow}{mu}{nu} for {ital M}{sub {ital W}{prime}}{gt}100 GeV/{ital c}{sup 2}, in {ital {bar p}p} collisions at {radical}{ital s} =1.8 TeV, using data taken with the Collider Detector at Fermilab. The nonobservation of these processes leads to a lower limit of 520 Gev/{ital c}{sup 2} (95% confidence level) on the mass of the {ital W}{prime}, assuming standard-strength couplings to three fermion generations.
