Abstract:

A combination of fifteen top quark mass measurements performed by the ATLAS and CMS experiments at the LHC is presented. The datasets used correspond to an integrated luminosity of up to 5 and 20 fb$^{−1}$ of
proton-proton collisions at center-of-mass energies of 7 and 8 TeV, respectively. The combination includes
measurements in top quark pair events that exploit both the semileptonic and hadronic decays of the top
quark, and a measurement using events enriched in single top quark production via the electroweak t
channel. The combination accounts for the correlations between measurements and achieves an
improvement in the total uncertainty of 31% relative to the most precise input measurement. The result
is m$_t$ = 172.52$\pm$0.14(stat)$\pm$ 0.30(syst) GeV, with a total uncertainty of 0.33 GeV.
