Melosh Construction Of Relativistic Three-Quark Baryon Wave Functions

Abstract

A method for constructing a complete set of relativistic three-quark states in light front dynamics is implemented for the nucleon, N${}^{\ast }$(1520) and N${}^{\ast }$(1535). This approach facilitates constructing states containing virtual antiquarks. A physical interpretation is provided in terms of transition amplitudes from quark to quark-gluon or quark-Goldstone boson Fock states of chiral dynamics generated by flux tube breaking expected in QCD at intermediate distances.
