Issues on magnon reflection
arXiv:0807.3646 · doi:10.1016/j.nuclphysb.2008.09.021
Abstract
Two questions related to reflections of magnons in AdS/CFT are discussed: namely the problem of explaining the (physical) poles of the reflection amplitudes using Landau type diagrams and the generalization of the Ghoshal-Zamolodchikov boundary state formalism to magnon reflections.
