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...

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...

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 ...

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...

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 (...

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, ...

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...

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 ...
