6-BODY LIGHT-FRONT TAMM-DANCOFF APPROXIMATION AND WAVE-FUNCTIONS FOR THE MASSIVE SCHWINGER MODEL

The spectrum of the massive Schwinger model in the strong coupling reg ion is obtained by using the light-front Tamm-Dancoff (LFTD) approxima tion up to and including six-body states. We numerically confirm that the two-meson bound state has a negligibly small six-body component. E mphasis is on the usefulness of the information about states (wave fun ctions). It is used for identifying the three-meson bound state among the states below the three-meson threshold. We also show that the two- meson bound state is well described by the wave function of the relati ve motion.
