Abstract

We study the leading quantum string correction to the dressing phase in the asymptotic Bethe Ansatz system for superstring in AdS ₃ × S ³ × T ⁴ supported by RR flux. We find that the phase should be different from the phase appearing in the AdS ₅ × S ⁵ case. We use the simplest example of a rigid circular string with two equal spins in S ³ and also consider the general approach based on the algebraic curve description. We also discuss the case of the AdS ₃ × S ³ × S ³ × S ¹ theory and find the dependence of the 1-loop correction to the effective string tension function h(λ) (expected to enter the magnon dispersion relation) on the parameter α related to the ratio of the two 3-sphere radii. This correction vanishes in the AdS ₃ × S ³ × T ⁴ case.
