Costituent Quark Picture out of QCD in two dimensions - on the Light-Cone

Abstract

Using DLCQ as a nonperturbative method, we test Fock-space truncations in ${\mathrm{QCD}}_{1+1}$ by studying the mass spectra of hadrons in colour SU(2) and SU(3) at finite harmonic resolution $K$. We include $q\bar{q}q\bar{q}$ states for mesons and up to $qqqq\bar{q}$ states for baryons. With this truncation, we give `predictions' for the masses of the first five states where finite $K$ effects are minimal.
