Abstract:

A combination of top-quark mass measurements performed by the ATLAS and CMS experiments at the LHC is presented. The dataset used corresponds to an integrated luminosity per experiment of up to 4.9

\rm{fb}^{-1}

of proton-proton collisions at a centre-of-mass energy of 7 TeV. The combination includes measurements in the {\rm{t \bar{t}}\to\mbox{lepton+jets}}, {\rm{t \bar{t}}\to\mbox{di-lepton}} and {\rm{t \bar{t}}\to\mbox{all jets}} channels. The resulting combined LHC measurement of the top-quark mass is m_{t} = 173.29 \pm 0.23 \mbox{ (stat)} \pm 0.92 \mbox{ (syst)} GeV, with a total uncertainty of

0.95

GeV.
