Search for electroweak production of single top quarks in p(p)over-bar collisions

B. Abbott, M. Abolins, Abramov, B. S. Acharya et autres

We present a search for electroweak production of single top quarks in the electron + jets and muon + jets decay channels. The measurements use approximate to 90 pb(-1) of data from Run 1 of the Fermilab Tevatron collider, collected at 1.8 …

Search for dilepton signatures from minimal low-energy supergravity in $p\overline{p}$ collisions at $\sqrt{s}$ = 1.8 TeV

B. Abbott, M. Abolins, V. Abramov, B. S. Acharya et autres

We report on a search for supersymmetry using the D empty set detector. The 1994-1996 data sample of roots = 1.8 TeV p (p) over bar collisions was analyzed for events containing two leptons (e or mu), two or more jets, and …

Extraction of the width of the W boson from measurements of $\sigma(p\vec{p} \rightarrow W + X) X B(W \rightarrow e\nu)$ and $\sigma(p\vec{p} \rightarrow Z + X) X B(Z \rightarrow ee)$ and their ratio

Measurement of [ital W] and [ital Z] boson production cross sections in p[bar p] collisions at [radical] (s) =1. 8 TeV

S. Grinstein, M. Mostafá, R. Piegaia, G. A. Alves et autres

DO/ has measured the inclusive production cross section of [ital W] and [ital Z] bosons in a sample of 13 pb[sup [minus]1] of data collected at the Fermilab Tevatron. The cross sections, multiplied by their leptonic branching fractions, for production in p[bar …

Small Angle J/{psi} Production in p{ovr p} Collisions at {radical} (s) =1.8 TeV

S. Grinstein, M. Mostafá, R. Piegaia, G. A. Alves et autres

This paper presents the first measurement of inclusive J/{psi} production cross section in the forward pseudorapidity region 2.5{le}{vert_bar}{eta}thinsp{sup J/{psi}}{vert_bar}{le}3.7 in p{ovr p} collisions at {radical} (s) =1.8 thinspthinspTeV. The results are based on 9.8 pb{sup {minus}1} of data collected using the D0 …

Dijet Mass Spectrum and a Search for Quark Compositeness in {ovr p}p Collisions at {radical} (s) =1.8 TeV

S. Grinstein, M. Mostafá, R. Piegaia, G. A. Alves et autres

Using the D0 detector at the 1.8 TeV{ovr p} p Fermilab Tevatron collider, we have measured the inclusive dijet mass spectrum in the central pseudorapidity region {vert_bar} {eta} {sub jet} {vert_bar} {lt}1.0 for dijet masses greater than 200 GeV/c{sup 2} . We …

Z{gamma} production in p{bar p} collisions at {radical} (s) =1.8TeV and limits on anomalous ZZ{gamma} and Z{gamma}{gamma} couplings

B. Gómez, B. Hoeneisen, P. Mooney, J. P. Negret et autres

We present a study of Z{gamma}+X production in p{bar p} collisions at {radical} (s) =1.8TeV from 97 (87)pb{sup {minus}1} of data collected in the ee{gamma} ({mu}{mu}{gamma}) decay channel with the D0 detector at Fermilab. The event yield and kinematic characteristics are consistent …

Study of the {ital ZZ}{gamma} and {ital Z}{gamma}{gamma} Couplings in {ital Z}({nu}{nu} ){gamma} Production

B. Gómez, B. Hoeneisen, P. Mooney, J. P. Negret et autres

We have measured the ZZ{gamma} and Z{gamma}{gamma} couplings by studying 13.1pb{sup -1} of p{bar p}{r_arrow}E/{sub t}{gamma}+X data at {radical}(s)=1.8TeV with the DO/ detector at the Fermilab Tevatron Collider. This is the first study of hadronic Z{gamma} production in the neutrino decay channel. …

Phenomenology of Muon Showers Underground

K. Davis, S. Michael Fall, R. B. Ingebretsen, R. O. Stenerson

Measurements of shower arrival directions (incident in a range of zenith angles between 40\ifmmode^\circ\else\textdegree\fi{} and 70\ifmmode^\circ\else\textdegree\fi{} and slant depth of rock between 2 \ifmmode\times\else\texttimes\fi{} ${10}^{5}$ and 6.5 \ifmmode\times\else\texttimes\fi{} ${10}^{5}$ g ${\mathrm{cm}}^{\ensuremath{-}2}$), structure, and intensities are used as the basis to develop a …
