AdS3/CFT2的敷料阶段

Dressing phases of AdS3/CFT2

Riccardo Borsato, Olof Ohlsson Sax, Alessandro Sfondrini, Bogdan Stefanski, Alessandro Torrielli

摘要:

通过求解最近发现的交叉关系和研究它们的奇异结构,确定了AdS 3 x S3 x T4上与IIB型弦论有关的AdS 3/CFT 2可积系统的全圈dressing相.所得的两个相相对于在AdS 5/CFT 4和AdS 4/CFT 3中出现的相呈现新颖的结构。在强耦合的制度,他们的领导秩序减少到普遍的Arutyunov-Frolov-Staudacher相的预期。我们还计算了它们的次领先阶,并与最近的单圈微扰结果进行了比较,并对它们的弱耦合展开进行了评论。

英文摘要:

We 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. We also compute their sub-leading order and compare it with recent one-loop perturbative results, and comment on their weak-coupling expansion.
