Composite Higgs models
Juan Pablo Hoyos Daza
TL;DR
This paper explores composite Higgs models based on specific cosets, analyzing their effective Lagrangians, gauge and fermion sectors, and estimating the Higgs potential to address the hierarchy problem.
Contribution
It provides a detailed construction and analysis of composite Higgs models using $SO(5)/SO(4)$ and $SO(6)/SO(5)$ cosets, including their effective Lagrangians and potential estimation.
Findings
The $SO(5)/SO(4)$ model closely resembles the Standard Model.
The $SO(6)/SO(5)$ model includes an additional singlet scalar.
Estimated Higgs potential suggests viability of these models.
Abstract
One of the solutions to the hierarchy problem of the Standard Model is the composite Higgs scenario, where the Higgs emerges as a composite pseudo-Nambu-Goldstone boson. In this work we present and study the basic characteristics of the composite Higgs scenario, based on the and cosets. We construct their effective Lagrangians through the Callan-Coleman-Wess-Zumino construction. The first coset does not differ much from the Standard Model and the second contains a singlet scalar in addition to the Higgs doublet. In these models we study the gauge sector, the fermion sector and we estimate the composite Higgs potential.
