TL;DR

This paper presents a detailed NLO QCD calculation for producing two bottom-antibottom pairs at the LHC, significantly improving the accuracy of cross-section predictions and reducing theoretical uncertainties.

Contribution

It provides the first full NLO QCD correction computation for this process, enhancing the precision of theoretical predictions for LHC experiments.

Findings

NLO corrections increase the cross-section by about 50%.

Theoretical uncertainties are substantially reduced with NLO inclusion.

Predictions are made for well-separated b-jet events.

Abstract

We report the results of a computation of the full next-to-leading order QCD corrections to the production of two $b\bar{b}$ pairs at the LHC. This calculation at the parton level provides predictions for well separated $b$-jets. The results show that the next-to-leading order corrections lead to an enhancement of the cross-section for the central scale choice by roughly 50% with respect to the leading order result. The theoretical uncertainty estimated by variation of the renormalization and factorization scales is strongly reduced by the inclusion of next-to-leading order corrections.
