Contribution

It provides a comprehensive comparison of dijet resonance search methods, results, and limits from multiple colliders, highlighting recent ATLAS and CMS findings.

Findings

No new dijet resonances observed

Stringent limits set on new particle masses

Comparison of experimental techniques and results

Abstract

We review the experimental searches for new particles in the dijet mass spectrum conducted at the CERN SppS, the Fermilab Tevatron Collider, and the CERN Large Hadron Collider. The theory of the QCD background and new particle signals is reviewed, with emphasis on the choices made by the experiments to model the background and signal. The experimental techniques, data, and results of dijet resonance searches at hadron colliders over the last quarter century are described and compared. Model independent and model specific limits on new particles decaying to dijets are reviewed, and a detailed comparison is made of the recently published limits from the ATLAS and CMS experiments.
