# Single-top quark cross-section measurements in ATLAS

## TL;DR

This paper reports comprehensive measurements of all three single top-quark production channels at the LHC, including new results at 13 TeV and evidence for the s-channel at 8 TeV, advancing understanding of top-quark production.

## Contribution

It provides the first measurements of single top-quark production in all channels at 13 TeV and evidence for the s-channel at 8 TeV, expanding experimental knowledge.

## Key findings

- First 13 TeV measurements of t-channel production
- First evidence of s-channel production at 8 TeV
- Detailed cross-section results for all channels

## Abstract

This article presents measurements of all three single top-quark production channels. Detailed measurements of $t$-channel single top-quark production using data collected by the ATLAS experiment in proton--proton collisions at a centre-of-mass energy of 8 TeV are shown as well es first results using 13 TeV at the LHC. The associated production of a top quark and a $W$ boson is presented for data collected at 13 TeV, while the first evidence of single top-quark production in the $s$-channel is shown for data collected at 8 TeV.
