  This is the second of two companion papers in which we continue developing
the construction of an elementary particle model with no Higgs. Here we show
that the recently identified non-perturbative field-theoretical feature,
alternative to the Higgs mechanism and capable of giving masses to quarks,
Tera-quarks and $W$, can also provide mass to leptons and Tera-leptons when the
model is extended to include, besides strong, Tera-strong and weak
interactions, also hypercharge. In the present approach elementary fermion
masses are not free parameters but are determined by the dynamics of the
theory. We derive parametric formulae for elementary particle masses from which
we can ``predict'' the order of magnitude of the scale of the new
Tera-interaction and get crude numerical estimates for mass ratios in fair
agreement with phenomenology. The interest of considering elementary particle
models endowed with this kind of non-perturbative mass generation mechanism is
that they allow solving some of the conceptual problems of the present
formulation of the Standard Model, namely origin of the electroweak scale and
naturalness.
