  Using lattice simulations we demonstrate from first principles the existence
of a non-perturbative mechanism for elementary particle mass generation in
models with gauge fields, fermions and scalars, if an exact invariance forbids
power divergent fermion masses and fermionic chiral symmetries broken at UV
scale are maximally restored. We show that in the Nambu-Goldstone phase a
fermion mass term, unrelated to the Yukawa operator, is dynamically generated.
In models with electro-weak interactions weak boson masses are also generated
opening new scenarios for beyond the Standard Model physics.
