Ratio of the Isolated Photon Cross Sections at \sqrt{s} = 630 and 1800 GeV
Author(s) :
Abazov, V. M.
Description :
The inclusive cross section for production of isolated photons has been
measured in \pbarp collisions at $\sqrt{s} = 630$ GeV with the \D0 detector at
the Fermilab Tevatron Collider. The photons span a transverse energy ($E_T$)
range from 7-49 GeV and have pseudorapidity $|\eta| < 2.5$. This measu...

Search for Leptoquark Pairs Decaying to nu-nu + jets in P Anti-P Collisions at s**1/2=1.8 TeV
Author(s) :
Abazov, V. M.
Description :
We present the preliminary results of a search for leptoquark ($LQ$) pairs
using (85.2 $\pm$ 3.7) pb$^{-1}$ of $p{\bar p}$ collider data collected by the
DO experiment at the Fermilab Tevatron from 1994-1996. We observe no evidence
for leptoquark production and set a limit on $\sigma (p{\bar p} \t...

Multiple Jet Production at Low Transverse Energies in pbarp Collisions at sqrt(s) = 1.8 TeV
Author(s) :
Abazov, V. M.
Description :
We present data on multiple jet production for transverse energies greater
than 20 GeV in pbarp collisions at sqrt(s) = 1.8 TeV. QCD calculations in the
parton shower approximation (PYTHIA) and in the next-to-leading order
approximation (JETRAD) show discrepancies with data for three and four-jet

Measurement of the ratio of differential cross sections for W and Z boson production as a function of transverse momentum in pbar p collisions at sqrt(s)=1.8 TeV
Author(s) :
Abazov, V. M.
Description :
We report on a measurement of the ratio of the differential cross sections
for W and Z boson production as a function of transverse momentum in
proton-antiproton collisions at sqrt(s) = 1.8 TeV. This measurement uses data
recorded by the D0 detector at the Fermilab Tevatron in 1994-1995. It
repres...

Search for mSUGRA in single-electron events with jets and large missing transverse energy in ppbar collisions at center of mass energy of 1.8 TeV
Author(s) :
Abazov, V. M.
Description :
We describe a search for evidence of minimal supergravity (mSUGRA) in 92.7
pb^(-1) of data collected with the D{\O}detector at the Fermilab Tevatron ppbar
collider at center of mass energy of 1.8 TeV. Events with a single electron,
four or more jets, and large missing transverse energy were used i...

Search for Narrow t-tbar Resonances in ppbar Collisions at \root{s} = 1.8 TeV
Author(s) :
Abazov, V. M.
Description :
A search for narrow resonances that decay into t-tbar pairs has been
performed using 130 pb^{-1} of data in the lepton+jets channel collected in
p-pbar collisions at \sqrt{s} = 1.8 TeV. There is no significant deviation
observed from the standard model, and upper limits at the 95 % confidence leve...

Search for New Particles in the Two-Jet Decay Channel with the D0 Detector
Author(s) :
Abazov, V. M.
Description :
We present the results of a search for the production of new particles
decaying into two jets in pbarp collisions at sqrt{s} = 1.8 TeV, using the
DZero 1992-1995 data set corresponding to 109 pb^-1. We exclude at the 95%
confidence level the production of excited quarks (q*) with masses below 775

Combination of CDF and D0 Results on W Boson Mass and Width
Author(s) :
Abazov, V. M.
Description :
The results based on 1992-95 data (Run 1) from the CDF and DO experiments on
the measurements of the W boson mass and width are presented, along with the
combined results.
We report a Tevatron collider average M_W = 80.456 +- 0.059 GeV. We also
report the Tevatron collider average of the directl...

Lifetime Difference and CP-Violating Phase in the B_s^0 System
Author(s) :
Abazov, V. M.
Description :
From an analysis of the decay Bs -> J/psi phi we obtain the width difference
between the light and heavy mass eigenstates, and the CP-violating phase.

Search for Supersymmetry in Di-Photon Final States at sqrt{s} = 1.96 TeV
Author(s) :
Abazov, V. M.
Description :
We report results of a search for supersymmetry (SUSY) with gauge-mediated
symmetry breaking in di-photon events collected by the D0 experiment at the
Fermilab Tevatron Collider in 2002--2006. In 1.1 fb$^{-1}$ of data, we find no
significant excess beyond the background expected from the standard ...
