Abstract

We establish the existence of the top quark using a 67 pb-1 data sample of p- p collisions at sqrt[s] = 1.8 TeV collected with the Collider Detector at Fermilab (CDF). Employing techniques similar to those we previously published, we observe a signal consistent with tt- decay to WWbb- , but inconsistent with the background prediction by 4.8σ. Additional evidence for the top quark is provided by a peak in the reconstructed mass distribution. We measure the top quark mass to be 176±8(stat)±10(syst) GeV/c2, and the tt- production cross section to be 6.8-2.4+3.6 pb.
