A study of retardation models for phenomenological interactions in hadronic physics

Abstract

A study of retardation models for the hadronic quark interaction is performed starting from a coordinate space calculation that elaborates a classical electrodynamics procedure. The possibility of constructing a corresponding quantum operator is critically analyzed also performing some numerical matrix element calculations. A comparison of the developed model with the Feynman diagram interaction at tree-level is studied, showing a substantial physical correspondence of the two models. Possible applications and generalizations are discussed.
