    • Exact form factors of the O(N) σ-model 

      Babujian, Hratchya M.; Foerster, Angela; Karowski, Michael (2013) [Artigo de periódico]
      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 ...
