Study of events with large total transverse energy produced in proton-antiproton collisions at (radical)s = 1.8 TeV

摘要

Properties of events originating from proton-antiproton interactions in which the total transverse energy, (Sigma)(vert bar)E(sub T)(vert bar), of the event exceeded 400 GeV are presented. These events were produced at the Fermilab Tevatron Collider operating at a center-of-mass energy of 1.8 TeV and recorded in the D0 detector. The authors describe their analysis method which minimizes the effect of multiple interactions in the data sample. Based on a data sample of 5.45 (+-) 0.65 pb(sup (minus)1), the topology of these hard scattering events as well as preliminary results for the cross-section, d(sigma)/d(Sigma)(vert bar)E(sub T)(vert bar), are presented and discussed.
