QFT Question

[Rade]

A question. Is it possible to use quantum field theory (QFT) to calculate the combined interactions of a set of three quarks, that is, a 3-quark bag {q,q,q}, with another set of two quarks {q,q}. I am not interested in interactions of 'free' particles with each other, but one bag interaction as a whole with another as a whole.

It's very complicated but, in principle, that's the way to go. It's not so easy to just apply QCD though and there's a lot of empirically gleaned knowledge. Lattice QCD is used a lot, computationally. You're talking about a meson and a baryon here, like for instance the meson going through the baryon; you could look up hadronic diffraction too.
