@misc{10481/70846, year = {2021}, month = {8}, url = {http://hdl.handle.net/10481/70846}, abstract = {Measurements of both the inclusive and differential production cross sections of a top-quark-antiquark pair in association with a Z boson (t (t) over barZ) are presented. The measurements are performed by targeting final states with three or four isolated leptons (electrons or muons) and are based on root s = 13 TeV proton-proton collision data with an integrated luminosity of 139 fb(-1), recorded from 2015 to 2018 with the ATLAS detector at the CERN Large Hadron Collider. The inclusive cross section is measured to be a sigma(t (t) over barZ)= 0.99 +/- 0.05 (stat.) +/- 0.08 (syst.) pb, in agreement with the most precise theoretical predictions. The differential measurements are presented as a function of a number of kinematic variables which probe the kinematics of the t (t) over barZ system. Both absolute and normalised differential crosssection measurements are performed at particle and parton levels for specific fiducial volumes and are compared with theoretical predictions at different levels of precision, based on a chi(2)/ndf and p value computation. Overall, good agreement is observed between the unfolded data and the predictions.}, organization = {CERN}, organization = {ANPCyT}, organization = {YerPhI, Armenia}, organization = {Australian Research Council}, organization = {Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPQ)}, organization = {Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP)}, organization = {Natural Sciences and Engineering Research Council of Canada (NSERC)}, organization = {NRC, Canada}, organization = {Canada Foundation for Innovation}, organization = {SSTC, Belarus}, organization = {Ministry of Education, Youth & Sports - Czech Republic Czech Republic Government}, organization = {Czech Republic Government}, organization = {DNRF, Denmark}, organization = {Danish Natural Science Research Council}, organization = {Centre National de la Recherche Scientifique (CNRS)}, organization = {CEA-DRF/IRFU, France}, organization = {SRNSFG, Georgia}, organization = {Federal Ministry of Education & Research (BMBF)}, organization = {HGF, Germany}, organization = {Max Planck Society}, organization = {Greek Ministry of Development-GSRT}, organization = {RGC, China}, organization = {Hong Kong SAR, China}, organization = {Israel Science Foundation}, organization = {Benoziyo Center, Israel}, organization = {Istituto Nazionale di Fisica Nucleare (INFN)}, organization = {Ministry of Education, Culture, Sports, Science and Technology, Japan (MEXT)}, organization = {Ministry of Education, Culture, Sports, Science and Technology, Japan (MEXT) Japan Society for the Promotion of Science}, organization = {CNRST, Morocco}, organization = {Netherlands Organization for Scientific Research (NWO) Netherlands Government}, organization = {RCN, Norway}, organization = {Ministry of Science and Higher Education, Poland}, organization = {NCN, Poland}, organization = {Portuguese Foundation for Science and Technology European Commission}, organization = {MNE/IFA, Romania}, organization = {JINR}, organization = {MESofRussia}, organization = {Russian Federation}, organization = {Ministry of Education, Science & Technological Development, Serbia}, organization = {MSSR, Slovakia}, organization = {Slovenian Research Agency - Slovenia}, organization = {MIZS, Slovenia}, organization = {DST/NRF, South Africa}, organization = {Spanish Government}, organization = {SRC, Sweden}, organization = {Wallenberg Foundation, Sweden}, organization = {SERI, Switzerland}, organization = {Swiss National Science Foundation (SNSF)}, organization = {Cantons of Bern and Geneva, Switzerland}, organization = {Ministry of Science and Technology, Taiwan}, organization = {Ministry of Energy & Natural Resources - Turkey}, organization = {UK Research & Innovation (UKRI) Science & Technology Facilities Council (STFC)}, organization = {DOEandNSF, USA}, organization = {BCKDF, Canada}, organization = {CANARIE, Canada}, organization = {ComputeCanada, Canada}, organization = {CRC, Canada}, organization = {IVADO, Canada}, organization = {Beijing Municipal Science & Technology Commission}, organization = {COST, France}, organization = {ERC, France}, organization = {ERDF, France}, organization = {Horizon 2020 and Marie Sklodowska-Curie Actions, European Union, France}, organization = {French National Research Agency (ANR)}, organization = {German Research Foundation (DFG)}, organization = {Alexander von Humboldt Foundation}, organization = {Thales Group}, organization = {Aristeia programmes}, organization = {EU-ESF, Greece}, organization = {Greek NSRF, Greece}, organization = {BSF-NSF, Israel}, organization = {German-Israeli Foundation for Scientific Research and Development}, organization = {La Caixa Banking Foundation, Spain}, organization = {CERCA Programme Generalitat de Catalunya, Spain}, organization = {GenT Programmes Generalitat Valenciana, Spain}, organization = {Goran Gustafssons Stiftelse, Sweden}, organization = {Royal Society of London}, organization = {Leverhulme Trust}, organization = {BMWFW, Austria}, organization = {Austrian Science Fund (FWF)}, organization = {Azerbaijan National Academy of Sciences (ANAS)}, organization = {D, Chile}, organization = {Minciencias, Colombia}, publisher = {Springer}, title = {Measurements of the inclusive and differential production cross sections of a top-quark-antiquark pair in association with a Z boson at root s=13 TeV with the ATLAS detector}, doi = {10.1140/epjc/s10052-021-09439-4}, author = {Aad, G. and Aguilar Saavedra, Juan Antonio and Atlas Collaboration}, }
