Six-body Light-Front Tamm-Dancoff approximation and wave functions for the massive Schwinger model

Abstract

The spectrum of the massive Schwinger model in the strong coupling region is obtained by using the light-front Tamm-Dancoff (LFTD) approximation up to including six-body states. We numerically confirm that the two-meson bound state has a negligibly small six-body component. Emphasis is on the usefulness of the information about states (wave functions). 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 relative motion. 11.10.Kk,11.10.St,11.15.Tk Typeset using REVTEX e-mail address: koji1scp@mbox.nc.kyushu-u.ac.jp e-mail address: zaki1scp@mbox.nc.kyushu-u.ac.jp e-mail address: mass1scp@mbox.nc.kyushu-u.ac.jp 1
