Measurements of associated $\textrm{t}\overline{\textrm{t}}\textrm{X}$

Abstract

Inclusive and differential cross section measurements of $\textrm{t}\overline{\textrm{t}}$-associated processes are performed at the ATLAS and CMS Collaborations with high precision. In this contribution, a selection of recent measurements of inclusive and differential measurements of the $\textrm{t}\overline{\textrm{t}}\gamma$, $\textrm{t}\overline{\textrm{t}}\textrm{Z}$ and $\textrm{t}\overline{\textrm{t}}\textrm{W}$ processes are presented. Searches for $\textrm{t}\overline{\textrm{t}}\textrm{t}\overline{\textrm{t}}$ production are presented for both collaborations, providing evidence for the process.Comment: Talk at the 15th International Workshop on Top Quark Physics, Durham, UK, 4-9 September 202
