Query: Measurement of the Top-Quark Mass in All-Hadronic Decays in p pbar
  Collisions at CDF II   We present a measurement of the top-quark mass, $M_{\mathrm{top}}$, in the
all-hadronic decay channel $t\bar{t} \to W^+b W^- \bar{b} \to q_1\bar{q}_2 b
q_3 \bar{q}_4 \bar{b}$. The analysis is performed using 310 pb$^{-1}$ of
$\sqrt{s}$=1.96 TeV $p\bar{p}$ collisions collected with the CDF II detector
using a multi-jet 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
$M_{\mathrm{top}}$=177.1 $\pm$ 4.9 (stat.) $\pm$ 4.7 (syst.) GeV/$c^2$.
