## Asymmetries in the Production of Lambda0 in 250 GeV/c pi+-, K+- and p -- Nucleon Interactions

Description : Using data from Fermilab fixed-target experiment E769, we have measured particle-antiparticle production asymmetries for Lambda0 hyperons in 250 GeV/c pi+-, K+- and p -- nucleon interactions. The asymmetries are measured as functions of Feynman-x (x_F) and p_t^2 over the ranges -0.12<=x_F<=0.12 an...

## Differential cross section for w boson production as a function of transverse momentum in proton-antiproton collisions at $\sqrt s$ = 1.8 TeV

Description : We report a measurement of the differential cross section for W boson production as a function of its transverse momentum in proton-antiproton collisions at sqrt{s} = 1.8 TeV. The data were collected by the D0 experiment at the Fermilab Tevatron Collider during 1994-1995 and correspond to an integra...

## Measurement of the ratio of differential cross sections for W and Z boson production as a function of transverse momentum in $p\bar p$ collisions at $\sqrt s$ = 1.8 TeV

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 represen...

## Search for first-generation scalar and vector leptoquarks

Description : We describe a search for the pair production of first-generation scalar and vector leptoquarks in the eejj and enujj channels by the D0 Collaboration. The data are from the 1992--1996 ppbar run at sqrt{s} = 1.8 TeV at the Fermilab Tevatron collider. We find no evidence for leptoquark production; in ...

## Search for heavy particles decaying into electron-positron pairs in $p\bar p$ collisions

Description : We present results of searches for technirho, techniomega, and Z' particles, using the decay channels technirho, techniomega, Z' -> e+e-. The search is based on 124.8 pb-1 of data collected by the D0 detector at the Fermilab Tevatron during 1992-1996. In the absence of a signal, we set 95% C.L. uppe...

## Direct search for charged Higgs bosons in decays of top quarks

Description : We present a search for charged Higgs bosons in decays of pair-produced top quarks in pbar p collisions at sqrt(s) = 1.8 TeV using 62.2 pb^-1 of data recorded by the D0 detector at the Fermilab Tevatron collider. No evidence is found for signal, and we exclude at 95% confidence most regions of the (...

## Multiple Jet Production at Low Transverse Energies in $p\bar p$ Collisions at $\sqrt s$ = 1.8 TeV

Description : We present data on multiple production of jets with transverse energies near 20 GeV in p-pbar collisions at Root(s) = 1.8 TeV. QCD calculations in the parton-shower approximation of PYTHIA and HERWIG and the next-to-leading order approximation of JETRAD are compared to the data for one, two, three, ...

## Search for large extra dimensions in the monojet + $\E_T$ channel with the D0 detector

Description : We present a search for large extra dimensions (ED) in p-pbar collisions at a center-of-mass energy of 1.8 TeV using data collected by the D0 detector at the Fermilab Tevatron in 1994-1996. Data corresponding to 78.8 +/- 3.9 pb^-1 are examined for events with large missing transverse energy, one hig...

## Observation of diffractively produced W and Z bosons in $\bar{p}p$ collisions at $\sqrt s$ = 1800 GeV

Description : Using the D0 detector, we have observed events produced in pbar-p collisions that contain W or Z bosons in conjunction with very little energy deposition (rapidity gaps'') in large forward regions of the detector. The fraction of W boson events with a rapidity gap (a signature for diffraction) is ...
