Dynamical chiral-symmetry breaking in asymptotically free theories with a slowly running coupling is analyzed. When the confinement scale ..lambda.. is much less than the cutoff M beyond which the theory cannot be used in isolation, the dynamical mass ..sigma..(p) starts from a value approx. =..lambda.. for momenta papprox. ..lambda... It then takes on the asymptotic form (lnp)/sup a//p/sup 2/ where a>1. In hypercolor theories this behavior generates sufficiently large fermion masses for a higher value of M than naively expected. This in turn could allow for an adequate suppression of flavor-changing neutral currents.
