Composite spin-1 resonances at the LHC

TL;DR

This paper investigates composite spin-1 resonances at the LHC, showing they can explain observed diboson excesses and exploring their detectability at higher energies.

Contribution

It demonstrates that vector resonances from composite Higgs models can account for LHC diboson signals and analyzes their parameter space considering experimental constraints.

Findings

Composite Higgs models can explain the 8 TeV diboson excess.

Parameter space consistent with electroweak and flavor constraints identified.

Projections for detection at 13 TeV LHC provided.

Abstract

In this paper, we discuss the signal of composite spin-1 resonances at the LHC. Motivated by the possible observation of a diboson resonance in the 8 TeV LHC data, we demonstrate that vector resonances from composite Higgs models are able to describe the data. We pay particular attention to the role played by fermion partial compositeness, which is a common feature in composite Higgs models. The parameter space that is both able to account for the diboson excess and passes electroweak precision and flavor tests is explored. Finally, we make projections for signals of such resonances at the 13 TeV run of the LHC.
