abstract = {The inclusive top quark pair (t ¯t) production
cross-section σt ¯t has been measured in proton–proton collisions
at
√
s = 13 TeV, using 36.1fb−1 of data collected
in 2015–2016 by the ATLAS experiment at the LHC. Using
events with an opposite-charge eμ pair and b-tagged jets, the
cross-section is measured to be:
σt ¯t = 826.4 ± 3.6 (stat) ± 11.5 (syst) ± 15.7 (lumi)
±1.9 (beam) pb,
where the uncertainties reflect the limited size of the data
sample, experimental and theoretical systematic effects, the
integrated luminosity, and the LHC beam energy, giving a
total uncertainty of 2.4%. The result is consistent with theoretical
QCD calculations at next-to-next-to-leading order.
It is used to determine the top quark pole mass via the
dependence of the predicted cross-section on mpole
t , giving
mpole
t = 173.1+2.0
−2.1 GeV. It is also combined with measurements
at
√
s = 7 TeV and
√
s = 8 TeV to derive ratios and
double ratios of t ¯t and Z cross-sections at different energies.
The same event sample is used to measure absolute and
normalised differential cross-sections as functions of singlelepton
and dilepton kinematic variables, and the results are
compared with predictions from various Monte Carlo event
generators.},
