- Summary:
- This report is a summary of the evidence for top quark production in {bar p}p collisions at a center of mass energy of 1.8 TeV which was obtained by the CDF Collaboration earlier this year. The data analyzed corresponds to an integrated luminosity of 19.3 pb{sup −1}, recorded with the CDF Detector at the Fermilab Tevatron Collider during 1992-1993. Three different search channels for t{bar t} production are used. A search for dilepton events finds 2 events, while two different methods of identifying b-quark jets in events with W+ ≥ 3 jets finds 6 and 7 events, respectively. The probability that the observed total yield is consistent with the estimated background of 5.96{sub −0.44}{sup +0.49} is 0.26%. Though the statistics are too limited to firmly establish the existence of the top quark, a natural interpretation of the excess is that it is due to t{bar t} production. Under this assumption, constrained mass fitting of a subset of events yields a top quark mass of 174±10{sub −12}{sup +13} GeV/c² and a t{bar t} production cross section of 13.9{sub −4.8}{sup +6.1}pb.
