CERN-EP-2019-203}, year = {2019}, abstract = {The inclusive top quark pair ($t\bar{t}$) production cross-section $\sigma_{t\bar{t}}$ has been measured in proton-proton collisions at $\sqrt{s}=13$ TeV, using $36.1$ fb$^{-1}$ of data collected in 2015-16 by the ATLAS experiment at the LHC. Using events with an opposite-charge $e\mu$ pair and $b$-tagged jets, the cross-section is measured to be: \begin{equation}\nonumber \sigma_{t\bar{t}} = 826.4 \pm 3.6\,\mathrm{(stat)}\ \pm 11.5\,\mathrm{(syst)}\ \pm 15.7\,\mathrm{(lumi)}\ \pm 1.9\,\mathrm{(beam)}\,\mathrm{pb}, \end{equation} where the uncertainties are due to data statistics, 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. It is used to determine the top quark pole mass via the dependence of the predicted cross-section on $m_t^{\mathrm{pole}}$, giving $m_t^{\mathrm{pole}}=173.1^{+2.0}_{-2.1}$ GeV. It is also combined with measurements at $\sqrt{s}=7$ TeV and $\sqrt{s}=8$ TeV to derive ratios and double ratios of $t\bar{t}$ and $Z$ cross-sections at different energies. The same event sample is used to measure absolute and normalised differential cross-sections as functions of single-lepton and dilepton kinematic variables, and the results compared with predictions from various Monte Carlo event generators.}, keywords = {p p: colliding beams (INSPIRE) / top: pair production (INSPIRE) / p p: scattering (INSPIRE) / channel cross section: measured (INSPIRE) / beam: energy (INSPIRE) / mass: pole (INSPIRE) / CERN LHC Coll (INSPIRE) / numerical calculations: Monte Carlo (INSPIRE) / final state: ((n)jet dilepton) (INSPIRE) / mass spectrum: (electron muon) (INSPIRE) / ATLAS (INSPIRE) / cross section: ratio: measured (INSPIRE) / energy dependence (INSPIRE) / differential cross section: measured (INSPIRE) / transverse momentum dependence (INSPIRE) / rapidity dependence (INSPIRE) / mass dependence (INSPIRE) / quantum chromodynamics (INSPIRE) / statistics (INSPIRE) / kinematics (INSPIRE) / experimental results (INSPIRE) / 13000 GeV-cms (INSPIRE)}, cin = {ATLAS}, cid = {I:(DE-H253)ATLAS-20120731}, pnm = {611 - Fundamental Particles and Forces (POF3-611)}, pid = {G:(DE-HGF)POF3-611}, experiment = {EXP:(DE-H253)LHC-Exp-ATLAS-20150101}, typ = {PUB:(DE-HGF)25 / PUB:(DE-HGF)29}, eprint = {1910.08819}, howpublished = {arXiv:1910.08819}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:1910.08819;\%\%$}, doi = {10.3204/PUBDB-2019-05253}, url = {https://bib-pubdb1.desy.de/record/429752}, }
