Hi
In Halzen's "Quarks & Leptons" all discussed particle interactions conserve particle number in some sense (Actually particle number is not conserved but if you count the particles minus the antiparticles before the reaction you get the same "particles minus the antiparticles" number after the reaction. Which is in some sense particle conservation since in the Feynman
diagram antiparticles are particles that propagate backwards in time).
However, I'm not sure if this is the most general process possible in particle physics. Moreover, in this book and in some others I haven't seen an explicit approach to particle destruction and creation which exists (I think in form of "second quantization"). Nevertheless, those methods are identified with quantum field theory (and the standard model).
So I guess my question is how does particle physics, quantum field theory, and second quantization relate to each other.
thx
