### On bound states of the light-cone AdS5 x S5 superstring

Seminar Room 1, Newton Institute

#### Abstract

We discuss the apparent bound states of the light-cone AdS5 x S5 superstring and its mirror model, and show that depending on a choice of the physical region there are one, two or 2^{M-1} solutions of the M-particle bound state equations sharing the same conserved charges. For very large but finite values of J, most of these solutions, however, exhibit various signs of pathological behavior. In particular, they might receive finite J correction to their energy which is complex, or the energy correction might exceed corrections arising due to finite J modifications of the Bethe equations thus making the asymptotic Bethe ansatz inapplicable.
