Query: Search for Top with D0 Detector in Dilepton Channel   Preliminary results from a search for high mass ttbar quark pair production
in ppbar collisions at sqrt(s)=1.8TeV with the D0 detector in the ee+jets,
emu+jets, and mumu+jets decay channels are presented. No conclusive evidence
for top quark production for an integrated luminosity of 13.5+/-1.6pb-1 is
observed.
