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

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
