Torrielli paper appears in Physical Review D

The paper “Dressing phases of AdS3/CFT2” by Alessandro Torrielli, in collaboration with Riccardo Borsato (Utrecht), Olof Ohlsson Sax (Utrecht), Alessandro Sfondrini (Utrecht), and Bogdan Stefanski (City University, London), has been accepted for publication in Physical Review D.  In the paper they determine the all-loop dressing phases of the AdS3/CFT2 integrable system related to type IIB string theory on AdS3 x S3 x T4 by solving the recently found crossing relations and studying their singularity structure. The two resulting phases present a novel structure with respect to the ones appearing in AdS5/CFT4 and AdS4/CFT3. In the strongly-coupled regime, their leading order reduces to the universal Arutyunov-Frolov-Staudacher phase as expected. They also compute their sub-leading order and compare it with recent one-loop perturbative results, and comment on their weak-coupling expansion.  The final form preprint can be found on the ArXiv .
