Abstract
Predictions for the ratio M(W)/m(t) arise in top condensation models f rom different methods. One type of prediction stems from Pagels-Stokar relations based on the use of Ward identities in the calculation of t he Goldstone boson decay constants and expresses M(W) in terms of inte grals containing the dynamically generated mass function Sigma(t)(p(2) ). Another type of prediction emerges from the renormalization group e quations via infrared quasi-fixed points of the running top quark Yuka wa coupling. We demonstrate in this paper that in the limit of a high cutoff these two methods lead to the same predictions for M(W)/m(t) an d M(W)/M(H) in lowest loop order.
