We show that a recently discovered non-perturbative field-theoreticalmechanism giving mass to elementary fermions, is also capable of generating amass for the electro-weak bosons and can thus be used as a viable alternativeto the Higgs scenario. A detailed analysis of this remarkable feature showsthat the non-perturbatively generated fermion and $W$ masses have theparametric form $m_{f}\sim C_f(\alpha)\Lambda_{RGI}$ and $M_W\sim g_wc_w(\alpha)\Lambda_{RGI}$, respectively, where the coefficients $C_f(\alpha)$and $c_w(\alpha)$ are functions of the gauge couplings, $g_w$ is the weakcoupling and $\Lambda_{\rm RGI}$ is the RGI scale of the theory. In view ofthese expressions, we see that to match the experimental values of the topquark and $W$ masses, we are led to conjecture the existence of a yetunobserved sector of massive fermions (that we denote Tera-fermions) subjected,besides ordinary Standard Model interactions, to some kind of super-stronggauge interactions (Tera-interactions), so that the full theory (SM plusTera-particles) will have an RGI scale $\Lambda_{\rm RGI}\equiv \Lambda_T$ inthe TeV region. This approach offers a solution of the mass naturalness problem(there is no fundamental Higgs), an understanding of the fermion mass hierarchyand a physical interpretation of the electro-weak scale as a fraction of$\Lambda_T$.
