Search for the top quark in lepton plus jets events at the Collider Detector at Fermilab
Abstract
A search for the Standard Model top quark in the lepton plus jets channel in pp collisions at $\sqrt{s}$ = 1800 GeV is described. The analysis was carried out on 19.3 pb$\sp{-1}$ of data collected with the Collider Detector at Fermilab in the 1992-1993 run. Events were selected by requiring a high $P\sb{T}$ electron or muon, missing transverse energy, three or more jets, and a large global sum of transverse energy. To further reduce background processes in the final event sample, at least one non-isolated lepton was required to act as a tag for the b-quarks. The expected background rate in this analysis is 1.80 $\pm$ 0.17 events. 7 events survive all the cuts. The probability for the expected background fluctuating to $\ge$7 events is 0.29% or 2.76$\sigma$.
