absorbs all our ontological ignorance into the word “quanta”.. it’s not quite clear to me what this means wrt field excitations Naievely I would say that it’s an excitation like a drop of water in a splash that breaks free.. for quantum fields the drops can only have 2/3
Specific “sizes”, as it were. By sizes I mean quantum numbers 3/3

And so cross sections would carry physical information relevant to this, hence why you think they’re the most relevant?
-
Well cross sections carry the same amount of QUANTUM information as the matrix elements, is my claim

pull on the thread: where do those ladder ops come from?
-
That’s a brilliant question imo.. one would think there’s some dynamics that govern it
