摘要：A hierarchical scheme to attack a coupled system of Bethe Salpeter equations for QCD bound states in the infinite momentum frame is discussed. Some results for Fock wave functions, in SYM2 with various parton multiplicities, are presented. The strong localization of these states in the LC configuration space is found. This allowes to confirm directly the string interpretation od two dimensional gauge theories and to determine the string tension directly from the spectrum. A new, sensitive method to look for the screening was also proposed. Its advantages were tested on the well known example of the massless Schwinger Model.
