Abstract
A measurement of the top quark mass (Mtop) in the all-hadronic decay channel is presented. It uses 5.8 fb[superscript −1] of pp¯ data collected with the CDF II detector at the Fermilab Tevatron Collider. Events with six to eight jets are selected by a neural network algorithm and by the requirement that at least one of the jets is tagged as a b -quark jet. The measurement is performed with a likelihood fit technique, which simultaneously determines Mtop and the jet energy scale (JES) calibration. The fit yields a value of Mtop=172.5±1.4(stat)±1.0(JES)±1.1(syst)GeV/c[superscript 2].
