Abstract
Dynamical chiral-symmetry breaking in asymptotically free theories with a slowly running coupling is analyzed. When the confinement scale is much less than the cutoff beyond which the theory cannot be used in isolation, the dynamical mass starts from a value for momenta and falls slowly for a significant range . It then takes on the asymptotic form where . In hypercolor theories this behavior generates sufficiently large fermion masses for a higher value of than naively expected. This in turn could allow for an adequate suppression of flavor-changing neutral currents.
