Colored Resonant Signals at the LHC: Largest Rate and Simplest Topology

TL;DR

This paper classifies colored resonances at the LHC, calculates their production rates, and uses current data to set bounds on their masses, highlighting the potential for discovering new physics with simple dijet signatures.

Contribution

It provides a comprehensive classification and effective interaction framework for colored resonances, and applies current LHC data to constrain their properties.

Findings

Production cross sections can reach 400-1000 pb at 1 TeV mass.

Current experimental bounds exclude resonances below 0.9 to 2.7 TeV.

The approach is adaptable for future searches and other decay modes.

Abstract

We study the colored resonance production at the LHC in a most general approach. We classify the possible colored resonances based on group theory decomposition, and construct their effective interactions with light partons. The production cross section from annihilation of valence quarks or gluons may be on the order of 400 - 1000 pb at LHC energies for a mass of 1 TeV with nominal couplings, leading to the largest production rates for new physics at the TeV scale, and simplest event topology with dijet final states. We apply the new dijet data from the LHC experiments to put bounds on various possible colored resonant states. The current bounds range from 0.9 to 2.7 TeV. The formulation is readily applicable for future searches including other decay modes.
