Integrable Spin Chains in Twisted Maximally Supersymmetric Yang-Mills Theory

We study an angular dipole deformation of maximally supersymmetric Yang-Mills (SYM) theory that preserves its classical scale invariance. Two-point functions of suitable single trace operators, restricted to an invariant plane, are determined by scaling dimensions computable via an integrable spin chain. This spin chain is a twisted version of the famous integrable spin chain of SYM theory. 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.
