Attraction between quarks is a fundamental aspect of QCD. It is plausible that several of the most profound aspects of Low-Energy QCD dynamics are connected to diquark correlations, including: paucity of exotics (which is the foundation of the quark model and of traditional nuclear physics), similarity of mesons and baryons, color superconductivity at high density, hyperfine splittings, ▵I=1/2 rule, and some striking features of structure and fragmentation functions. After a brief overview of these issues, I discuss how diquarks can be studied in isolation, both phenomenologically and numerically, and present approximate mass differences for diquarks with different quantum numbers. The Mass-Loaded generalization of the Chew-Prautschi formula provides an essential tool.
