2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/54381We briefly review results on two-dimensional supersymmetric quantum field theories that exhibit factorizable particle scattering. Our particular focus is on a series of $N\!=\!1$ supersymmetric theories, for which exact $S$-matrices have been obtained. A Thermodynamic Bethe Ansatz (TBA) analysis for these theories has confirmed the validity of the proposed $S$-matrices and has pointed at an interesting `folding' relation with a series of $N\!=\!2$ supersymmetric theories.3 pages, wstwocl.sty, epsfig.sty, talk delivered at the HEP95 Conference of the EPS, Brussels, July/August 1995High Energy Physics - Theorytext
