Key Points

  • The aim is to analyze the four-top quark production process at the LHC with NLO QCD corrections applied.
  • Used NLO accuracy in perturbative QCD for the analysis.
  • Employed the narrow-width approximation for decay processes.
  • Preserved spin correlations at NLO accuracy in QCD.
  • Highlighted sensitivities to cuts on invariant mass of light jets.
  • Identified significant higher-order QCD effects on the four-top production process.
  • Demonstrated the preservation of spin correlations without approximations.
  • Result sensitivity varied based on the cuts applied to the invariant mass of jets.

Abstract

We discuss the results for the four-top quark production process at the LHC at NLO accuracy in perturbative QCD for the 3 3 ℓ decay channel. The QCD corrections are applied in both the production and the decay stages of the four top quarks by employing the narrow-width approximation. The spin correlations are therefore preserved at NLO accuracy in QCD without any approximation. We summarize the impact of higher-order QCD effects by highlighting the sensitivity of the results on the cut applied on the invariant mass of the two hardest light jets in the process.
