Fundamental matter and SDLCQ

We consider a bound state problem for a family of supersymmetric gauge theo ries with fundamental matter. These theories can be obtained by a dimension al reduction from three dimension to 1 + 1 of supersymmetric QCD and subseq uent truncation of some of the fields. We find that the models without adjo int scalar converge to well-defined continuum limits. We also find the crit ical value of coupling at which an additional massless state is observed. B y contrast, the models containing adjoint scalars, seem to have a continuou s mass spectrum in the limit of infinite volume.
