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 QCD2 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.
