We present the first observation of the all hadronic decay of t (t) over bar pairs. The analysis is performed using 109 pb(-1) of p (p) over bar collisions at root s = 1.8 TeV collected with the Collider Detector at Fermilab. We observe an excess of events with five or more jets, including one or two b jets, relative to background expectations. Based on this excess we evaluate the production cross section to be in agreement with previous results. We measure the top mass to be 186 +/- 10 +/- 12 GeV/c(2).

Abstract

We present the first observation of the all hadronic decay of t (t) over bar pairs. The analysis is performed using 109 pb(-1) of p (p) over bar collisions at root s = 1.8 TeV collected with the Collider Detector at Fermilab. We observe an excess of events with five or more jets, including one or two b jets, relative to background expectations. Based on this excess we evaluate the production cross section to be in agreement with previous results. We measure the top mass to be 186 +/- 10 +/- 12 GeV/c(2).
