This posts shows code examples of Feynman diagrams of top quark pair production in association with charm quarks in proton-proton collisions. The charm quarks are highlighted with orange jet cones, inspired by the diagrams in this publication on the search for this process at ATLAS. The same search was performed at CMS. For a nice talk on the search for H → cc decay in ttH production at the LHC, where this ttcc is a large background, see this recorded CERN seminar by Sebastian Wuchterl.
