Construction and clustering properties of the 2-d non-linear sigma-model form factors: O(3), O(4), large n examples

J. Balog, P. Weisz

Multi-particle form factors of local operators in integrable models in two dimensions seem to have the property that they factorize when one subset of the particles in the external…
