Twisted Magnons
Abhijit Gadde, Leonardo Rastelli

TL;DR
This paper investigates the properties of twisted magnons in N=2 orbifold spin chains, using symmetry principles to determine their dispersion relations and S-matrices despite broken integrability.
Contribution
It introduces a method to fix magnon dispersion and scattering matrices based on SU(2|2) symmetry, independent of integrability.
Findings
Dispersion relations are determined by symmetry.
Two-body S-matrices are explicitly constructed.
Results hold across exactly marginal couplings.
Abstract
We study spin chains for superconformal quiver gauge theories in the moduli space of N=2 orbifolds. Independent of integrability, which is generally broken, we use the centrally extended SU(2|2) symmetry of the magnons to fix their dispersion relations and two-body S-matrices, as functions of the exactly marginal couplings.
