LHC multijet events as a probe for anomalous dimension-six gluon interactions

TL;DR

This paper demonstrates that multi-jet events at the LHC provide the most effective way to constrain dimension-six gluon interactions, surpassing other analyses in sensitivity and allowing certain operators to be neglected in future studies.

Contribution

It shows that multi-jet production is the optimal channel for constraining dimension-six gluon operators, providing limits that exceed those from Higgs and top analyses.

Findings

Multi-jet events set strong bounds on gluon operators.

Limits on new physics scale are in the multi-TeV range.

Pure Yang-Mills operator can be neglected in most analyses.

Abstract

Higher-dimensional multi-gluon interactions affect essentially all effective Lagrangian analyses at the LHC. We show that, contrary to common lore, such operators are best constrained in multi-jet production. Our limit on the corresponding new physics scale in the multi-TeV range exceeds the typical reach of global dimension-6 Higgs and top analyses. This implies that the pure Yang-Mills operator can safely be neglected in almost all specific higher-dimensional analyses at Run II.
