摘要：
The top quark mass m(t) in the top quark condensation model is calculated with the ladder Schwinger-Dyson equation including the gluon exchange. Instead of the Pagels-Stokar approximation, for fixing the value of the coupling constant the Goldstone boson decay constant is calculated with the solution of the covariant Bethe-Salpeter equation corresponding to the Goldstone boson. By introducing an interaction of the form (g'/LAMBDA-2) PSI(L)(i)lambda(a)t(R)t(R)lambda(a)PSI(L)iBAR in the model an m(t) value lower than 200 GeV can be obtained. The effect of higher dimensional operators is investigated.
