Catalysis of the $\langle \bar bb\rangle$ condensate in the composite Higgs model

The problem of appearance of quark masses through the mechanism of dynamical breaking of the $SU(2)_L \times U(1)_R$ symmetry of electroweak interactions has been studied within a model with local four-quark interactions, which result in the formation of a $\langle \bar tt\rangle$ condensate and composite Higgs bosons. We show that this process catalyzes $\bar bb$ condensation in the presence of an arbitrarily weak' t Hooft interaction. The spectrum of composite scalar excitations has been calculated. An expression obtained for the mass of a standard Higgs boson significantly improves the agreement of the top-condensation model with the experiment. It has been shown that the standard Higgs boson under the Nambu sum rules should have three partners with the same mass of about $245$ GeV and different electric charges. The possibility of a transition of the system to a chiral symmetric phase, which is accompanied by the corresponding change in the spectrum of elementary excitations, is discussed.
