Interpretations of the ATLAS Diboson Anomaly

TL;DR

This paper provides a theoretical interpretation of the ATLAS diboson anomaly at 2 TeV using a right-handed model with extra W' and Z' bosons, considering various experimental constraints.

Contribution

It introduces a phenomenological right-handed model to explain the diboson excess, incorporating multiple experimental constraints and discussing alternative explanations.

Findings

The model can account for the observed diboson excess.

Constraints from decay widths and production cross sections are satisfied.

Other potential explanations are briefly considered.

Abstract

Recently, the ATLAS Collaboration recorded an interesting anomaly in diboson production with excesses at the diboson invariant mass around 2 TeV in boosted jets of all the $WZ$, $W^+ W^-$, and $ZZ$ channels. We offer a theoretical interpretation of the anomaly using a phenomenological right-handed model with extra $W'$ and $Z'$ bosons. Constraints from narrow total decay widths, dijet cross sections, and $W/Z + H$ production are taken into account. We also comment on a few other possibilities.
