Triviality, perturbation theory and $Z \to b\overline{b}$

We compute the large-m_t contributions to the Zb\overline b vertex in the Standard Model non-perturbatively using both the 1/\nc and the 1/\nf expansions. Triviality and its consequences for the perturbative result are systematically analyzed. In particular, we point out that the effect of trivialit...
