Constraining Spin-One Color-Octet Resonances Using CDF and ATLAS Data

TL;DR

This paper investigates constraints on spin-one color-octet resonances (colorons) at hadron colliders using dijet data from CDF and ATLAS, establishing bounds on their couplings in a model-independent manner.

Contribution

It provides the first comprehensive, model-independent analysis of coloron production constraints using existing collider dijet data from Tevatron and LHC.

Findings

CDF data yields the most stringent limits on coloron couplings.

ATLAS data at 7 TeV also constrains coloron parameters.

The study demonstrates the effectiveness of dijet data in probing new colored resonances.

Abstract

In this paper, we study the production of spin-one color-octet resonances (colorons) at hadron colliders in a model independent way. We use dijets data measured by CDF (at \sqrt{s}=1.96 TeV and L=1.13$ 1/pb) and ATLAS (at \sqrt{s}=7$ TeV and L=315 1/nb) collaborations at the Tevatron and the LHC respetively to impose limits on the coupling of colorons to fermions. We show that CDF data still produce the more stringent limits on the coloron coupling constant.
