Composite ALPs in Composite Higgs Models
Journal article, 2025
We study the effective Lagrangian for the Axion-Like Particle (ALP) arising in a class of composite Higgs models. We discuss the peculiarities of the coupling to the quark sector specific of these models, including flavor violating terms. We then confront the main bounds from rare B-meson decays.
