# $t\bar{t}$ + $Z$ / $W$ / $t\bar{t}$ at ATLAS

## TL;DR

This paper summarizes recent ATLAS measurements of top-quark pair production with Z/W bosons and four top quarks using 36.1 fb$^{-1}$ of 13 TeV LHC data, providing insights into top quark interactions.

## Contribution

It presents the latest experimental results on top-quark associated productions and four-top processes at the LHC, enhancing understanding of top quark physics.

## Key findings

- Observation of four top quark production
- Data consistent with Standard Model predictions

## Abstract

The newest results from the ATLAS Collaboration for the production of a top-quark pair in association with a $Z$ or $W$ boson, and for the production of four top quarks, are summarised in these proceedings. The measurements were performed with 36.1 fb$^{-1}$ of proton-proton collision data from the Large Hadron Collider at a centre-of-mass energy of 13 TeV.
