We present a measurement of the ttbar production cross section in ppbar collisions at root(s) = 1.8TeV by the D0 experiment at the Fermilab Tevatron. The measurement is based on data from an integrated luminosity of approximately 125 pb^-1 accumulated during the 1992-1996 collider run. We observe 39 ttbar candidate events in the dilepton and lepton+jets decay channels with an expected background of 13.7+-2.2 events. For a top quark mass of 173.3GeV/c^2, we measure the ttbar production cross section to be 5.5+-1.8 pb.

We report on a search for second generation scalar leptoquarks with the D0 detector at the Fermilab Tevatron {ital pp}{ovr bar} collider at {radical}{ital s}=1.8TeV. This search is based on 12.7pb{sup {minus}1} of data. Second generation leptoquarks are assumed to be produced in pairs and to decay into a muon and quark with branching ratio {beta} or into a neutrino and quark with branching ratio 1{minus}{beta}. We obtain cross section times branching ratio limits as a function of leptoquark mass and set lower limits on the leptoquark mass at the 95% confidence level. {copyright} {ital 1995} {ital The} {ital American} {ital Physical} {ital Society}.

A search for signals of new physics has been carried out in the channel p pbar -> gamma gamma + ETmiss. This signature is expected in various recently proposed supersymmetric (SUSY) models. We observe 842 events with two photons having transverse momentum ET(g) > 12 GeV and pseudorapidity |eta(g)| gamma gamma ETmiss + X) where ET(g) > 12 GeV, |eta(g)| 25 GeV.
