That should be selfcontained and certainly discusses exact S-matrices and 2d QED, so the answer to your questions might be in there. | |

| Sep 19, 2016 at 13:20 | comment | added | asv | @CarloBeenakker: I am not well familiar with the Schwinger model, but my impression was that in this model fermions are massless. I did not assume that in my question. I believe this assumption may lead to some extra divergences in the S-matrix. | |
| Sep 19, 2016 at 13:11 | comment | added | Carlo Beenakker | if I am not mistaken in 2D QED (Schwinger model) there are only confined fermions; how might we then even define a scattering matrix, when there are no asymptotically free states at infinity? | |
