      More fundamentally would be the invariant matrix element for a given process, it essentially decouples all of the quantum stuff from the SR and all of the things on your list are functions of these

      The ontology of QFT in my mind is one of the most difficult possible tasks.. a “hard problem” if you will, to abuse Daniel Chalmers phrase

      It requires at its heart understanding wtf the QFT formalism is describing

      There’s a great PSE post on this.. take the field operator φ³.. as a field operator it’s not even clear what this even means

      Lmao yeah it’s pretty hilarious to see the PSE answer questions about physical significance of X, where we have the most abstract mathematical formalisms as far divorced from human experience as possible

      Though if I’m not mistaken the S matrix and correlation functions and the invariant matrix element are essentially the same thing with different names

      The smatrix is just a correlation function with some extra creation and annihilation operators

      Hmm I guess the path from correlation function —> Smatrix seems to involve changes in information to me. Like if it was only a Fourier transform I’d be able to conceptualize how they’re the same, but I have a hard time of doing so now

      You’re right about that ontologically

      I was speaking purely mathematically, to my detriment

          Yeah I think this could be a weakness of structural realism, but no matter how much I think about it it’s still hard to say anything that makes sense ontologically of correlation functions and the other mathematical objects/processes that we’re dealing with

          Possible that there are better questions to ask: does this have physical significance? Yes. Should we expect it to be preserved in a more fundamental theory? Yes. Then, here’s why....
