Nuclear and subatomic physics is the study of physical systems at scales smaller than atoms but not necessarily elementary particles (which are the focus of the closely related field of elementary particle physics), particularly protons and neutrons. It deals with the strong and weak nuclear forces, and is thoroughly connected with quantum mechanics, particularly quantum electrodynamics (QED) and quantum chromodynamics (QCD). Much of nuclear and subatomic physics is related to fundamental symmetries like the charge-parity-time (CPT) symmetry.
