   Abstract:
   We present a measurement of the top-quark mass Mtop in the all-hadronic decay channel t[overline t]-->W+bW-[overline b]-->q1[overline q]2bq3[overline q]4[overline b]. The analysis is performed using 310 pb-1 of sqrt(s)=1.96 TeV p[overline p] 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 Mtop=177.1$\pm$4.9(stat)$\pm$4.7(syst) GeV/c2.
