The hexagon form factor has proven a powerful integrability tool for the calculation of correlation functions in N=4 supersymmetric Yang-Mills (SYM). It seems only natural to wonder whether this tool can also be applied in less supersymmetric theories. Good testing grounds are, for instance, marginally deformed theories as well as orbifold theories. For these theories, the deformed spectral problem is well understood and an extension of integrable methods to higher-point functions is desirable.
In this talk, I will begin by reviewing the hexagon form factor for N=4 SYM and the ingredients needed for its evaluation. I will then consider the beta-deformed and orbifolded theories and discuss how a modified hexagon formalism can be used for the evaluation of three-point functions.
