Abstract:

We calculate the typical size of loop corrections to electroweak observables arising from non-standard

Z {\overline t } t

and

W t b

vertices. We use an effective Lagrangian formalism based on the electroweak gauge group

SU(2)_L\times U(1)_Y \rightarrow U(1)_{EM}

. Limits on the non-standard model top quark couplings from electroweak observables are presented and compared with previously obtained limits.

gauge field theory: SU(2) x U(1)
electroweak interaction: symmetry breaking
symmetry breaking: electroweak interaction
effective Lagrangian
top
coupling: top
top: coupling
vertex function: (Z0 2top)
vertex function: (W top bottom)
electroweak interaction: correction
