Possible Duplicate: What is a complete book for quantum field theory? At the moment I am studying Piron: Foundations of Quantum Physics, Jauch: Foundations of Quantum Mechanics, and Ludwig: Foundations of Quantum Mechanics All of them discuss nonrelativistic quantum mechanics. Now my question is, if there are corresponding approaches to quantum field theory (in particular aiming to the standard model of particle physics). Edit (in response to noldorin's comment): I think if one knows the books mentioned above, the question...

In quantum field theory with a mass gap, why do states in the asymptotic future/past turn out to have a Fock space structure? For a free quantum field theory, that's trivial, but why is that the case for interacting theories? In fact, the more one thinks about it, the less clear it becomes. If the quanta of the "fundamental" field is unstable, it doesn't show up in the asymptotic Fock space. If the quanta is confined, it also doesn't show...
