# Extracting the top-quark running mass using $t\bar{t}$+1-jet events produced at the Large Hadron Collider

## TL;DR

This paper calculates next-to-leading order QCD corrections for top-quark pair plus jet production at the LHC, using a mass renormalization scheme to extract the top-quark running mass from experimental data.

## Contribution

It introduces a method to determine the top-quark running mass by combining NLO QCD calculations with LHC data analysis.

## Key findings

- Determined the top-quark running mass from LHC data.
- Provided NLO QCD corrections for $t\bar{t}$+jet production.
- Compared theoretical predictions with experimental measurements.

## Abstract

We present the calculation of the next-to-leading order QCD corrections for top-quark pair production in association with an additional jet at hadron colliders, using the modified minimal subtraction scheme to renormalize the top-quark mass. The results are compared to measurements at the Large Hadron Collider run I. In particular, we determine the top-quark running mass from a fit of the theoretical results presented here to the LHC data.
