Nucleon’s Possible Quark-Diquark Structure
Diquarks appeared in literatures almost as early as quarks did. There have been several different definitions for a diquark, from nearly a pure mathematical tool to a bound object of certain quark combinations. We first make a review on work related to this structure. From considerable success in these applications, it would be interesting to see if this structure can be consistently applied to explain nucleons’ properties. We make such an effort here, and take the nucleons’ charge RMS radii as an example. A simple model is demonstrated, and extremely nice results are obtained. Some other possible applications will also be discussed.
