Abstract

We present a measurement of the top-quark mass M(top) in the all-hadronic decay channel t (t) over bar -> W(+)bW(-)(b) over bar -> q(1)(q) over bar (2)bq(3)(q) over bar (4)(b) over bar. The analysis is performed using 310 pb(-1) of root s=1.96 TeV p (p) over bar collisions collected with the CDF II detector using a multijet trigger. The mass measurement is based on an event-by-event likelihood which depends on both the sample purity and the value of the top-quark mass, using 90 possible jet-to-parton assignments in the six-jet final state. The joint likelihood of 290 selected events yields a value of M(top)=177.1 +/- 4.9(stat)+/- 4.7(syst) GeV/c(2).
