Magnon Bound-state Scattering in Gauge and String Theory

  title={Magnon Bound-state Scattering in Gauge and String Theory},
  author={Radu Roiban},
It has been shown that, in the infinite length limit, the magnons of the gauge theory spin chain can form bound states carrying one finite and one strictly infinite R-charge. These bound states have been argued to be associated to simple poles of the multi-particle scattering matrix and to world sheet solitons carrying the same charges. Classically, they can be mapped to the solitons of the complex sine-Gordon theory. Under relatively general assumptions we derive the condition that simple… CONTINUE READING
