(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
Measurements of differential cross sections of top quark pair production in association with jets by the ATLAS experiment at the LHC are presented. The measurements are performed as functions of the top quark transverse ...
