Abstract:

We have measured the p(T) distribution of top quarks that are pair produced in pp collisions at sqrt[s] = 1.8 TeV using a sample of tt decays in which we observe a single high- p(T) 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- p(T) top quarks suggested in some models of anomalous top quark pair production.

Abstract:

The data collected by DO detector was used to study the decay of heavy particles into electron-positron pairs during collisions. The dielectron invariant mass spectra for the events with both electrons in central region and with one electron in central region and other in forward region of central calorimeter (CC)/end calorimeter (EC) were also studied. PYTHIA was used to determine the product of cross section and branching ratio for the system. The superimposed histograms represented the estimated spectrum from standard model processes and instrumental effects.
