abstract = {The normalized differential cross section for top-quark pair production in association
with at least one jet is studied as a function of the inverse of the invariant mass
of the t¯t + 1-jet system. This distribution can be used for a precise determination of the
top-quark mass since gluon radiation depends on the mass of the quarks. The experimental
analysis is based on proton-proton collision data collected by the ATLAS detector at the
LHC with a centre-of-mass energy of 7TeV corresponding to an integrated luminosity of
4.6 fb−1. The selected events were identified using the lepton+jets top-quark-pair decay
channel, where lepton refers to either an electron or a muon. The observed distribution is
compared to a theoretical prediction at next-to-leading-order accuracy in quantum chromodynamics
using the pole-mass scheme. With this method, the measured value of the
top-quark pole mass, mpole
t , is:
mpole
t = 173.7 ± 1.5 (stat.) ± 1.4 (syst.) +1.0
−0.5 (theory) GeV.
This result represents the most precise measurement of the top-quark pole mass to date.},
