Mesonic spectrum of two-dimensional supersymmetric theories - art. no. 045019

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 of supersymmetric QCD from three dimensions to 1 + 1 and subse quent truncation of some of the fields. We find that the models without adj oint scalar converge to well-defined continuum limits and calculate the res ulting spectra of these theories. We also find the critical value of coupli ng at which an additional massless state is observed. By contrast, the mode ls containing adjoint scalars seem to have a continuous mass spectrum in th e limit of infinite volume.
