Contribution

It introduces a diagonally twisted integrable spin chain model for the deformed SYM, extending integrability techniques to new deformed gauge theories.

Findings

Two-point functions are determined by integrable spin chain spectra.

The twisted spin chain matches string theory predictions.

The work advances understanding of twisted integrable AdS/CFT correspondence.

Abstract

We study an angular dipole deformation of maximally supersymmetric Yang-Mills theory (SYM) that preserves its classical scale invariance. We show that two-point functions of suitable single trace operators, restricted to an invariant plane, are determined by scaling dimensions computable from an integrable spin chain. This spin chain is a diagonally twisted version of the famous integrable spin chain of SYM. It matches expectations from the dual string theory perfectly, presenting a precision test of holography in this new setting, and an important step to understanding general twisted integrable AdS/CFT.
