摘要：

We calculate the typical size of loop corrections to electroweak observables arising from nonstandard Z(t) over bart$ and Wtb vertices. We use an effective Lagrangian formalism based on the electroweak gauge group SU(2)(L) x U(1)(Y) --> U(1)(EM). Limits on the nonstandard model top quark couplings from electroweak observables are presented and compared with previously obtained limits.
