Study of tp¯ collisions using total transverse energy
Abstract
We analyze a sample of W+jet events collected with the Collider Detector at Fermilab (CDF) in pp¯ collisions at √s=1.8 TeV to study tt¯ production. We employ a simple kinematical variable H, defined as the scalar sum of the transverse energies of the lepton, neutrino, and jets. For events with a W boson and four or more jets, the shape of the H distribution deviates by 3.8 standard deviations from that expected from known backgrounds to tt¯ production. However, this distribution agrees well with a linear combination of background and tt¯ events, the agreement being best for a top mass of 180 GeV/c2.
