Abstract

We construct a composite two-Higgs-doublet model (2HDM) within the context of dilaton effective field 24 theory. This EFT describes the particle spectrum observed in lattice simulations of a near-conformal SU(3) 25 gauge field theory. A second Higgs doublet is naturally accommodated within the EFT,...
