Abstract
The effective quark models with quasilocal interaction are used for descrip tion of two composite Higgs doublets, in strong coupling (tricritical) regi me below the compositeness scale Lambda(C). 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 Hig gs fields are derived for investigation of how the chiral symmetry is broke n. The comparison of their asymptotics at high energies allows to realize t he chiral symmetry restoration characteristic for the underlying gauge theo ries with vector coupling to fermions. In this way we make hints on the exi stence of new physical phenomena in the TeV energy region.
