# LHC constraints on color octet scalars

## TL;DR

This paper analyzes LHC data to set constraints on color octet scalars in the MW model, finding that masses below 1 TeV are not excluded and that coupling constraints are generally weak.

## Contribution

It provides the first comprehensive comparison of LHC experimental limits with the MW model's parameter space, clarifying the mass and coupling constraints.

## Key findings

- Masses below 1 TeV are not excluded for color octet scalars.
- Constraints on coupling constants are generally weaker than theoretical bounds.
- The parameter η_D is an exception with stronger constraints.

## Abstract

We extract constraints on the parameter space of the MW model by comparing the cross-sections for dijet, top-pair, dijet-pair, $t\bar t t \bar t$ and $b\bar b b \bar b$ productions at the LHC with the strongest available experimental limits from ATLAS or CMS at 8 or 13 TeV. Overall we find that masses below 1 TeV have not been excluded for color octet scalars as it is often claimed in the literature. The constraints that can be placed on coupling constants are typically weaker than those from existing theoretical considerations, with the exception of the parameter $\eta_D$.
