Elementary particle masses from a non-perturbative anomaly

A novel dynamical mechanism of elementary particle mass generation has recently been conjectured and numerically demonstrated by lattice simulations in a simple SU(3) gauge model where a SU(2) doublet of strongly interacting fermions is coupled to a complex scalar field doublet through a Yukawa and a Wilson-like term. As a first step towards building a natural (à la ’t-Hooft) extension of the Standard Model, we argue that in the presence of weak gauge interactions the mechanism above, acting as a kind of non-perturbative anomaly, yields for both elementary fermions and weak gauge bosons effective masses proportional to the Λ–parameter of the theory, with particle–specific gauge coupling dependent prefactors.
