Abstract

We describe few aspects of the quantum symmetries of some massless two-dimensional field theories. We discuss their relations with recent proposals for the factorized scattering theories of the massless PCM₁ and O(3)_θ=π sigma models. We use these symmetries to propose massless factorized S-matrices for the su(2) sigma models with topological terms at any level, alias the PCM_k models, and for the su(2)-coset massless flows.
