Measurement of the top quark mass in all-jet events

We describe a measurement of the mass of the top quark from the purely hadronic decay modes of t (t) over bar pairs using all-jet data produced in p (p) over bar collisions at roots = 1.8 TeV at the Fermilab Tevatron Collider. The data, which correspond to an integrated luminosity of 110.2 +/- 5.8 pb(-1), were collected with the DO detector from 1992 to 1996. We find a top quark mass of 178.5 +/- 13.7(stat) +/- 7.7(syst) GeV/c(2). (C) 2004 Elsevier B.V. All rights reserved.
