On the compatibility of the diboson excess with a gg-initiated composite sector

TL;DR

This paper investigates whether recent LHC heavy resonance signals could originate from a new confining gauge sector linked to composite Higgs models, analyzing potential signatures and future detection prospects.

Contribution

It proposes a novel interpretation of diboson excesses as signals from a pure-gauge confining sector with specific resonance properties, connecting collider data to composite Higgs theories.

Findings

Lightest resonances could be neutral, spin-zero and -two, resembling radion and massive graviton signatures.

LHC8 data can be used to improve sensitivity to this scenario.

Future LHC13 runs could further characterize these potential signals.

Abstract

In this paper we explore the possibility that recent results by ATLAS and CMS searching for heavy resonances decaying into bosons could be a first hint of a new sector of pure-gauge confining physics, possibly linked to the origin of the Higgs as a Composite Higgs. The lightest resonances (glueballs) of this new sector would be neutral, spin-zero and -two, and their behaviour would resemble that of a radion and a massive graviton of extra-dimensions. We outline how LHC8 data could be used to improve sensitivity on this scenario, as well as future characterization during the LHC13 run.
