The origin of the first and third generation fermion massesin a technicolor scenario

We argue that the masses of the first and third fermionic generations, which are respectively of the order of a few MeV up to a hundred GeV, originate from a dynamical symmetry breaking mechanism leading to masses of the order 
, where 
is a small coupling constant, and μ, in the case of the first fermionic generation, is the scale of the dynamical quark mass (
MeV). For the third fermion generation μ is the value of the dynamical techniquark mass ( GeV). We discuss how this possibility can be implemented in a technicolor scenario, and how the mass of the intermediate generation is generated.
