A study on the effective anomalous interactions, up to dimension 5, of
the top quark with the electroweak gauge bosons is made in the non-li
near Chiral Lagrangian approach. Bounds on the anomalous dimension fou
r terms are obtained from their contribution to low energy data. Also,
the potential contribution to the production of top quarks at hadron
colliders (the Tevatron and the LHC) and the electron Linear Collider
from both dimension 4 and 5 operators is analyzed.
