abstract = {The mass of the top quark is measured in a data set
corresponding to 4.6 fb$^{-1}$ of proton-proton collisions
with centre-of-mass energy $\sqrt{s}=7$ TeV collected by the
ATLAS detector at the LHC. Events consistent with hadronic
decays of top-antitop quark pairs with at least six jets in
the final state are selected. The substantial background
from multijetproduction is modelled with data-driven methods
that utilise the number of identified $b$-quark jets and the
transverse momentum of the sixth leading jet,which have
minimal correlation. The top-quark mass is obtained from
template fits to the ratio of three-jet to dijet mass. The
three-jet mass is calculated from the three jets produced in
a top-quark decay. Using these three jets the dijet mass is
obtained from the two jets produced in the $W$ boson decay.
The top-quark mass obtained from this fit is thus less
sensitive to the uncertainty in the energy measurement of
the jets. A binned likelihood fit yields a top-quark mass of
$m_{t} = 175.1 \pm 1.4$ (stat) $\pm 1.2$ (syst) GeV.},
