What do you guys think does the most explanatory work in QFT? @InertialObservr @MattersDarkly
Correlation functions, S-matrix, scattering elements, cross sections, etc.? Lots of people have talked about realism wrt. fields and particles, but not much wrt. these objects

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
