Meson spectrum in $QC{D}_2$ revisited

Abstract

Recently it has been shown that in two dimensions is possible to add new Lorentz invariant terms built with fractions containing the null vector $n=(1,1)$. In this work, we have computed the meson spectrum following the 't Hooft model in $QC{D}_2$ incorporating these new kinds of terms. We found these new terms does not affect the meson spectrum. We have computed the 't Hooft model with a new regulator. We have introduced a gluon mass and we have recovered the 't Hooft result when this parameter is set to zero.
