Fixing the Quantum Three-Point Function

Understand

We propose a new method for the computation of quantum three-point functions for operators in su(2) sectors of N=4 super Yang-Mills theory.

• The method is based on the existence of a unitary transformation relating inhomogeneous and long-range spin chains.
• This transformation can be traced back to a combination of boost operators and an inhomogeneous version of Baxter's corner transfer matrix.
• We reproduce the existing results for the one-loop structure constants in a simplified form and indicate how to use the method at higher loop orders.
