Talk:Haag–Łopuszański–Sohnius theorem

Limitations section

The limitations section currently says:

The theorem only deals with "visible symmetries, i.e., with symmetries of the S-matrix" and thus it is still possible that "the fundamental equations may have a higher symmetry". Expressed differently, this means the theorem does not restrict broken symmetry, but only unbroken symmetries.

It seems to me that one of these is backwards, but I can't correct it because I can't tell which. The bit before the "Expressed differently" seems to disallow symmetries of the S-matrix, and therefore broken symmetries of the physics, but allow symmetries of the underlying unified model. The bit after "Expressed differently" seems to be exactly the opposite. Of course, I may have misunderstood the physics here, in which case a clarification is required.
