Abstract
We study how the simple predictions of the Nambu-Jona-Lasinio model of composite Higgs bosons are modified when quark interactions more singular than the nonderivative four-quark interaction are added. The t-quark mass is no longer restricted to ≳ 200 GeV, the simple mass relation between the t-quark and the scalar Higgs boson is lost, and the energy scale of the quark couplings can be chosen as low as we wish. Implications in experimental testability of this class of models are briefly discussed.Keywords
