Measurement of the Top-Quark Mass in the All-Hadronic Channel using the full CDF data set

Understand

The top-quark mass M_top is measured using top quark-antiquark pairs produced in proton-antiproton collisions at a center-of-mass energy of 1.96 TeV and decaying into a fully hadronic final state.

• The full data set collected with the CDFII detector at the Fermilab Tevatron Collider, corresponding to an integrated luminosity of 9.3 fb-1, is used.
• Events are selected that have six to eight jets, at least one of which is identified as having originated from a b quark.
• In addition, a multivariate algorithm, containing multiple kinematic variables as inputs, is used to discriminate signal events from background events due to QCD multijet production.
