Abstract

We study the leading quantum string correction to the dressing phase in the asymptotic Bethe Ansatz system for superstring in AdS3 × S3 × T 4 supported by RR flux. We find that the phase should be different from the phase appearing in the AdS5 ×S5 case. We use the simplest example of a rigid circular string with two equal spins in S3 and also consider the general approach based on the algebraic curve description. We also discuss the case of the AdS3 × S3 × S3 × S1 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 parameters α related to the ratio of the two 3-sphere radii. This correction vanishes intheAdS3×S3×T4 case.
