Vector resonances at LHC Run II in composite 2HDM

TL;DR

This paper analyzes a composite two Higgs doublet model driven by strong dynamics, predicting new vector resonances at the LHC, and assesses their detectability and constraints with upcoming LHC data.

Contribution

It provides a systematic analysis of vector resonance signals in a composite 2HDM and evaluates their experimental viability at the LHC.

Findings

Model predicts accessible vector resonances at LHC.

Current data will tightly constrain the model.

Viability persists with future LHC runs.

Abstract

We consider a model where the electroweak symmetry breaking is driven by strong dynamics, resulting in an electroweak doublet scalar condensate, and transmitted to the standard model matter fields via another electroweak doublet scalar. At low energies the effective theory therefore shares features with a type-I two Higgs doublet model. However, important differences arise due to the rich composite spectrum expected to contain new vector resonances accessible at the LHC. We carry out a systematic analysis of the vector resonance signals at LHC and find that the model remains viable, but will be tightly constrained by direct searches as the projected integrated luminosity, around 200 fb$^{-1}$, of the current run becomes available.
