## 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... Repository : arXiv Language(s) : Undetermined ## 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 ...

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...

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...

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... Repository : arXiv Language(s) : Undetermined ## 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 ... Repository : arXiv Language(s) : Undetermined ## 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...
