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.
