Pair production - which theory does it belong to

[71GA]

I am wondering in which theory pair productioon is described? Is it field theory, particle physics or quantum physics? I am sorry for such a basic question, but i need this info to find some books which will explain pair production mathematically and not by waving hands... (like allover the web)

Thank you.

Quantum field theory
This is a field theory, it is a quantum theory, and (nearly?) all calculations in particle physics use quantum field theory.

Would you recommend any books for pair production?

It would depend on how deeply you want to get into it. Judging by the work you did and the questions you were asking in this thread, you'll get a long ways just by knowing two things:
1) Pair production obeys all the conservation laws.
2) The relativistic energy-momentum relationship: $E^2 = (pc)^2 + (mc^2)^2$

Actually this is so called scattering theory. This is indeed a subdivision of QFT.

Could you write down in my other topic, how i could use this equation? To achieve same $h \nu$ which i get by conservation of energy and conservation of momentum.
