Abstract

In this article we present a method for constructing two-point functions in the spirit of the hexagon proposal, which leads us to propose a “square form factor”. Since cutting the square gives us two squares, we can write a consistency condition that heavily constrains such form factors. In particular, we are able to use this constraint to reconstruct the Gaudin through the forest expansion of the determinant appearing in its definition. We also use this procedure to compute the norm of off-shell Bethe states for some simple cases.
