Abstract

We investigate the analytic properties of the exact magnon S matrix of string theory on AdS₃ x S³ x T⁴ with R-R flux. We show that the previously proposed dressing factors have the exact double-pole/zero structure expected from Landau box diagrams. This constitutes a strong consistency check of our dressing factors, much as the Dorey-Hofman-Maldacena poles do for the all-loop dressing factor in AdS₅ x S⁵.
