Recent developments in NLO QCD calculations: the particular case of pp -> ttjj

TL;DR

This paper reviews recent progress in NLO QCD calculations, focusing on the pp -> ttjj process at the LHC, demonstrating the capabilities of the HELAC-NLO system in computing cross sections.

Contribution

It presents the first NLO QCD calculations for the pp -> ttjj process at the LHC using the HELAC-NLO framework, including integrated and differential cross sections.

Findings

NLO calculations for pp -> ttjj are successfully performed.

Results include both integrated and differential cross sections.

The HELAC-NLO system effectively computes complex QCD processes.

Abstract

A very brief status of next-to-leading order QCD calculations is given. As an example the next-to-leading order QCD calculations to the pp -> ttjj processes at the CERN Large Hardon Collider are presented. Results for integrated and differential cross sections are shown. They have been obtained in the framework of the HELAC-NLO system.
