Composite two-Higgs models and chiral symmetry restoration

The effective quark models with quasilocal interaction are used for description of two composite Higgs doublets, in strong coupling (tricritical) regime below the compositeness scale ΛC. The low energy effective action of Two-Higgs Doublet Standard Model is obtained in the large Nc and large-log approximation. The two-point correlators of scalar and pseudoscalar Higgs fields are derived for investigation of how the chiral symmetry is broken. The comparison of their asymptotics at high energies allows to realize the chiral symmetry restoration characteristic for the underlying gauge theories with vector coupling to fermions. In this way we make hints on the existence of new physical phenomena in the TeV energy region.
