Abstract

Recent results on top-quark mass measurements with the ATLAS detector using proton-proton collisions at the Large Hadron Collider are presented. These results correspond to the measurements in the $t\bar{t}$ all-hadronic and dilepton channels at $\sqrt{s} = 8\ \mathrm{TeV}$ collisions and an integrated luminosity of $20\ \mathrm{fb}^{-1}$.
