We show that the equivalence theorem approximating one-loop gauge sector diagrams by including only Goldstone bosons in the loop gives a remarkably poor approximation to the amplitude for the decay H→ γγ and for the process γγ→ HH. At one loop, large logarithms can arise that evade power counting arguments.
