Abstract

By reanalyzing the influence of the anomalous $Z t ˉ t$ couplings on the $Z \to b b ˉ$ decay process, we pointed out the ambiguity in the conventional treatment of the effective Lagrangian approach, because of the possible existence of large contributions given by constant terms beyond the leading cutoff dependent term.
