The Equivalence Theorem and infrared divergences

Abstract

We look at the Equivalence Theorem as a statement about the absence of polynomial infrared divergences when $m_W\to 0$. We prove their absence in a truncated toy model and conjecture that, if they exist at all, they are due to couplings between light particles.

Minor changes in the argument for clarity. More references have been added. 16 pages, LaTeX, no extra figures
