Contribution

It provides a comprehensive overview of the latest top-quark measurements and the methodologies used for their combination at the LHC.

Findings

Combined top-quark cross sections and mass measurements are presented.

Uncertainty categories and correlation patterns are analyzed.

Results include W boson polarization and charge asymmetry in top-quark events.

Abstract

A review of recent combinations of top-quark measurements performed at the LHC, by the ATLAS and CMS collaborations, is provided. The typical uncertainty categorisations, and their assumed correlation patterns are presented, together with the results of the combinations of the top-quark pair and single top-quark production cross sections, the top-quark mass, as well as of the $W$ boson polarisation and the charge asymmetry in $t\bar t$ events.
