Abstract

We have measured the pT distribution of top quarks that are pair produced in pp̅ collisions at √s=1.8 TeV using a sample of tt̅ decays in which we observe a single high-pT charged lepton, a neutrino, and four or more jets. We use a likelihood technique that corrects for the experimental bias introduced due to event reconstruction and detector resolution effects. The observed distribution is consistent with the standard model prediction. We use these data to place limits on the production of high-pT top quarks suggested in some models of anomalous top quark pair production.
