TL;DR
This paper calculates the pair production of scalar color octets (sgluons) at the LHC to next-to-leading order in QCD, demonstrating large production rates and significant quantum effects, validating the MadGolem framework.
Contribution
It provides the first NLO QCD calculation of sgluon pair production, confirming the robustness of the automated MadGolem tool for new physics signals.
Findings
Large NLO production rates for sgluons.
Significant quantum effects depending on sgluon mass.
Mild distribution shifts consistent with multi-jet merging calculations.
Abstract
Scalar color octets are generic signals for new physics at LHC energies. We examine their pair production at the LHC to next-to-leading order QCD. This computation serves as another test of the fully automized MadGolem framework. We find large NLO production rates and sizeable quantum effects which depend on the sgluon mass. The shift in the sgluon distributions is mild and in good agreement with a multi-jet merging calculation.
