Quark physics describes the structure of nucleons, which are composed of three quarks. In this context, the discussion highlights that nucleons do not have a single central quark or a valence quark, but rather require three-body coordinates for accurate representation. The ground state of a nucleon is characterized by zero orbital angular momentum, referred to as an S state, although atomic physics terminology is not directly applicable to this field. Understanding these concepts is crucial for grasping the complexities of nucleon structure.
