High-energy scattering in gauge theories and integrable spin chains

TL;DR

This paper explores the connection between high-energy scattering in gauge theories and integrable spin chains, revealing that certain reggeon interactions can be modeled by an open spin chain system.

The model applies in the leading log approximation at large N_C

Provides a new integrable systems perspective on high-energy scattering

Abstract

In the leading log approximation and at large $N_C$ the interaction of two fermionic and one gluonic reggeons is described by an integrable system corresponding to an open spin chain.
