dc.description.abstract
A general form factor formula for the O(N ) σ-model is constructed and applied
to several operators. The large N limits of these form factors are computed
and compared with the 1/N expansion of the O(N ) σ-model in terms of Feynman
graphs and full agreement is found. In particular, O(3) and O(4) form factors
are discussed. For the O(3) σ-model several low particle form factors are
calculated explicitly.
