The CST: Its Achievements and Its Connection to the Light Cone

I review the applications of the Covariant Spectator Theory (CST) since its inception in 1969. Applications discussed here include calculations of NN scattering, 3N bound states, electromagnetic form factors of few-nucleon systems, and the recent successes in describing the dynamical generation of quark mass and the meson spectrum using a chirially invariant quark–antiquark interaction that includes confinement. The common origin of the Light Cone technique and the CST, which dates back to the 1970’s, will be discussed.
