Limits on Non-Standard Top Quark Couplings from Electroweak Measurements
Abstract
We calculate the typical size of loop corrections to electroweak observables arising from non-standard Z t t and W t b vertices. We use an effective Lagrangian formalism based on the electroweak gauge group SU(2)L× U(1)Y → U(1)EM. Limits on the non-standard model top quark couplings from electroweak observables are presented and compared with previously obtained limits.
