Content
Higgs compositeness, i.e. the framework in which the Higgs boson arises as a Goldstone boson of a novel strong interaction, provides an elegant way to circumvent the hierarchy problem in the standard model. In order to study compositeness, the first step is to understand the global symmetry breaking pattern in the novel strong force, which has to be compatible with the symmetries of the standard model. In this talk, I discuss the low energy effective field theory resulting from the $SU(4) \to Sp(4)$ breaking pattern (arising, for instance, in $Sp(2N)$ gauge theories coupled with two Dirac fermions) and outline a programme of lattice simulations aimed at measuring the spectrum and other phenomenologically relevant parameters (such as the $\rho-\pi-\pi$ coupling) of the effective model.
