S. Dittmaier, P. Uwer, S. Weinzierl
TL;DR
This paper provides a next-to-leading order QCD calculation for top-quark pair production with an extra jet, crucial for understanding signals and backgrounds at the LHC.
Contribution
It introduces the first NLO QCD computation for top-quark pair plus one jet production, including both integrated and differential cross sections.
Findings
NLO QCD corrections significantly affect cross section predictions.
Differential cross sections are computed for various kinematic variables.
Results improve theoretical precision for LHC top-quark studies.
Abstract
Top-quark pair production with an additional jet is an important signal and background process at the LHC. We present the next-to-leading order QCD calculation for this process and show results for integrated as well as differential cross sections.
