| Abstract | We study both the CP-even and CP-odd effective chiral Lagrangians of a next-to-minimal composite Higgs model, with a symmetry breaking pattern depicted by the coset SO(6)/SO(5) through the sigma/ omega decomposition, in which the Goldstone matrix of the coset is decomposed in terms of the standard model Higgs doublet and an additional scalar singlet s at the electroweak scale. The effective Lagrangians are described by the electroweak chiral operators up to p(4) order, with a function dependence on the Higgs boson and new scalar s, named Higgs function. This function in the effective Lagrangian incorporates the Higgs nonlinearity or vacuum misalignment effects in the next-to-minimal composite Higgs model, leads to various Higgs couplings deviated from the standard model ones, and also indicates the relations among different Higgs couplings in the low energy. Matching to the Higgs effective field theory below the electroweak scale, we obtain various low-energy observables such as the electroweak oblique parameters, anomalous triple and quartic gauge couplings, anomalous couplings of Higgs to gauge bosons, in which the Higgs nonlinearity effects are encoded in the ratio. xi v(2) / f(2) of the electroweak scale and the new physics scale. As a by-product, we obtain a generalized Maurer-Cartan equation sourced by non-Abelian gauge fields. The equation interprets the dynamical interplay between nonlinear realization of pseudo-Nambu-Goldstone bosons (or Higgs) and the gauge fields, and provides a nonlinear generalization of the dynamical electroweak symmetry breaking. |
