The paper discusses a model where electroweak symmetry breaking is triggered by a light composite Higgs, which emerges from a strongly-interacting sector as a pseudo-Goldstone boson. The model is characterized by two parameters: $m_{\rho}$, the mass scale of the new resonances, and $g_{\rho}$, their coupling. An effective low-energy Lagrangian approach is used to describe the interactions of the Higgs with the Standard Model (SM) fields, focusing on operators that are sensitive to the new strong force and those that are sensitive to the spectrum of the resonances. The authors identify two classes of operators: those that are genuinely sensitive to the new strong force and those that are sensitive to the spectrum of the resonances. They discuss the phenomenological prospects for the Large Hadron Collider (LHC) and the International Linear Collider (ILC), including high-energy longitudinal vector boson scattering, strong double-Higgs production, and anomalous Higgs couplings. The paper also explores the possibility that the top quark could be a composite object of the strong sector. The authors provide a detailed construction of the low-energy effective Lagrangian and relate it to explicit models such as the Holographic Higgs and Little Higgs models. They derive bounds on the parameters $m_{\rho}$ and $g_{\rho}$ from electroweak precision data and discuss the implications for the model's predictions.The paper discusses a model where electroweak symmetry breaking is triggered by a light composite Higgs, which emerges from a strongly-interacting sector as a pseudo-Goldstone boson.
