## TL;DR

This paper develops a comprehensive effective field theory basis for a Higgs-like dilaton, enabling distinctions from the Standard Model Higgs and composite Higgs models through specific observables.

## Contribution

It introduces a complete bosonic basis for a Higgs-like dilaton at subleading order and compares it with existing models to identify key observables.

## Key findings

- Identified observables that distinguish a Higgs-like dilaton from other models.
- Provided a systematic framework for analyzing dilaton couplings.
- Enhanced understanding of effective field theories for Higgs-like particles.

## Abstract

A Higgs-like dilaton owns couplings that differ from those of the Standard Model Higgs and of a generic Composite Higgs. The complete bosonic basis for a Higgs-like dilaton is presented at the first subleading order. A comparison with the Standard Model, the Standard Model Effective Field Theory and the generic Lagrangian for the minimal $SO(5)/SO(4)$ Composite Higgs model is performed. Observables that can disentangle the different hypotheses are identified.
