A two-Higgs-doublet interpretation of a small Tevatron $Wjj$ excess

TL;DR

This paper proposes that a two-Higgs-doublet model can explain the Tevatron $Wjj$ excess, predicting correlated signals in other channels that are close to detectability, especially if the excess cross section is below 2 pb.

Contribution

It introduces a specific two-Higgs-doublet model explanation for the Tevatron $Wjj$ excess and predicts correlated signals in $\gamma\gamma$ and $W^+ W^- b ar{b}$ channels.

Findings

The model can account for the $Wjj$ excess with appropriate parameters.

Predicted signals in $\gamma\gamma$ and $W^+ W^- b ar{b}$ are near current detection thresholds.

The explanation is most viable if the excess cross section is less than about 2 pb.

Abstract

We show that a $Wjj$ excess in Tevatron data could be explained in the context of the standard non-supersymmetric two-Higgs-doublet model for appropriately chosen parameters. Correlated signals in the $\gamma\gamma$ and $W^+ W^- b \anti b$ final states are predicted and are on the verge of being detectable. The proposed model is most attractive if the cross section for the $Wjj$ excess is $\lsim 1-2\pb$.
