Description
arious integrable models of QFT have been recently constructed in a mathematical satisfactory way by means of operator-algebraic techniques. Some of these, such as the O(N)-invariant nonlinear sigma models, can be seen as a toy model for 4-dimensional nonabelian gauge theories. It would be physically even more interesting to consider gauge theories with bound states, where moreover we allow fusions among particles. Examples of interesting integrable models in this respect are the sine-Gordon and the Thirring models. This talk will report on ongoing work regarding the mathematical construction of such models, and explore their relevance for physics.
