LHC Test of CDF $Wjj$ anomaly

TL;DR

This paper evaluates the LHC's ability to test the CDF $Wjj$ anomaly, finding most models inconsistent with LHC data unless specific quark contributions are assumed, and discusses future search prospects.

Contribution

It provides a comprehensive analysis of the LHC's potential to confirm or exclude the CDF $Wjj$ anomaly across various models, focusing on valence quark contributions.

Findings

Most models are incompatible with LHC results.

Valence quark contributions are crucial for compatibility.

LHC has significant discovery/exclusion potential for the anomaly.

Abstract

We discuss a test of the CDF dijet anomaly at the LHC. The recent observed dijet mass peak at the CDF is well fitted by a new particle with a mass of around 150 GeV, which decays into two jets. In this paper, we focus on only $Wjj$ signal to avoid model dependence, and comprehensively study the LHC discovery/exclusion reach. We found almost all the models are inconsistent with the result of the LHC, unless only valence quarks contribute the new process. We also discuss further prospects of the LHC search for this anomaly.
