Top-quark mass measurement in the all-hadronic $t\bar{t}$ decay channel at $\sqrt{s}$ = 8 TeV with the ATLAS detector

Understand

The top-quark mass is measured in the all-hadronic top-antitop quark decay channel using proton-proton collisions at a centre-of-mass energy of $\sqrt{s}$ = 8 TeV with the ATLAS detector at the CERN Large Hadron Collider.

• The data set used in the analysis corresponds to an integrated luminosity of 20.2 fb$^{-1}$.
• The large multi-jet background is modelled using a data-driven method.
• The top-quark mass is obtained from template fits to the ratio of the three-jet to the dijet mass.
