How about recursive Unclear if you are asking about nuclear physics (i.e. the behavior of quarks and gluons when they are mainly color singlets in the form of protons and neutrons effectively exchanging mesons) or particle physics (i.e. the behavior of what used to be called "elementary" particles). >equations or series?

Which one you like is a matter of taste. A working knowledge of quantum field theory is needed to appreciate this model. Its predictive power is outstanding as long as the energy of the interactions is high enough that one can calculate an answer. It has yet to be able to calculate the mass of a proton; the low energy sector is really untested. Nuclear physics is basically the low energy sector of QCD, with the complication of having lots of particles interacting with one another. The most complete description of the field is probably a pair of massive (and expensive) tomes: deShalit and Feshbach (Theoretical Nuclear Physics Vol. I, Nuclear Structure) and a new book by Feshback (basically vol. II on reactions, but I do not think it is called volume 2). This material requires a good working knowledge of quantum mechanics with more of an emphasis on many-body theory than field theory altho the latter is helpful at times. It is an intense book. -- J.
