Title: Evidence for top quark production in {ital {bar p}p} collisions at {radical}{ital s}=1.8 TeV

Abstract

A search[1] for the top quark with the Collider Detector at Fermilab (CDF) in a sample of {ital {bar p}p} collisions at {radical}{ital s}=1.8 TeV with an integrated luminosity of 19.3{plus_minus}0.7 pb{sup {minus}1} is summarized. We find 12 events consistent with either two {ital W} bosons, or a {ital W} boson and at least one {ital b} jet. The probability that the measured yield is consistent with the background is 0.26%. Though the statistics are too limited to establish firmly the existence of the top quark, a natural interpretation of the excess is that it is due to {ital t{bar t}} production. Under this assumption, constrained fits to individual events yield a top quark mass of 174{plus_minus}10{sup +13}{sub {minus}12} GeV/c{sup 2}. The {ital t{bar t}} production cross section is measured to be 13.9{sup +6.1}{sub {minus}4.8} pb. Some implications of the measured value of the top mass are discussed. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
