Query: Comment on H --> gamma gamma and the role of the decoupling theorem and
  the equivalence theorem   I am commenting on the paper Gastmans, Wu and Wu, which recently obtained new
support by a paper by Christova and Todorov, about a new calculation of the H
--> gamma gamma rate mediated by the W boson loop, and the lack of decoupling
of the heavy states which mediate the decay. We remind the reader that the
heavy Higgs limit is dominated by the contribution from the longitudinal W
bosons, which in the limit m_H >> M_W are represented by the charged Higgs
ghosts according to the equivalence theorem. The corresponding contribution is
missing in Gastmans, Wu and Wu as well as in the new paper by Christova and
Todorov.
