Measurement of the top-quark mass in the all-hadronic channel using the full CDF data set

The top-quark mass Mtop is measured using top quark-antiquark pairs produced in proton-antiproton collisions at a center-of-mass energy of 1.96 TeV and that decay into a fully hadronic final state. The full data set collected with the CDF II detector at the Fermilab Tevatron Collider, corresponding...
