Massless integrable quantum field theories and massless scattering in 1+1 dimensions
arXiv:hep-th/9310058
Abstract
These lecture notes provide an elementary introduction to the study of massless integrable quantum field theory in 1+1 dimensions using ``massless scattering''. Some previously unpublished results are also presented, including a non-perturbative study of Virasoro conserved quantities.
