Large--order behavior of non--decoupling effects and triviality

Abstract

We compute some non--decoupling effects in the standard model, such as the $\rho$ parameter, to all orders in the coupling constant expansion. We analyze their large order behavior and explicitly show how it is related to the non--perturbative cutoff dependence of these non--decoupling effects due to the triviality of the theory.
