Which, if I read your response right, would be if two of the masses
were equal or both zero. But I still don't see the problem with one of
them being zero.

Then again, a lot of your explanation DID go over my head, so I
probably missed a valuable point or three. I honestly don't know much
of anything about QFT [This is QFT, right? :P]. The book I got on it
happens to be only useful as a paper weight as of now, until I learn
more about Lie algebras/groups.
