AdS 4/CFT 3对偶是AdS/CFT系统可积和精确可解的一个新例子。然而，在精确解（4 B + 4F散射态）和临界超弦理论的8B +8 F横向振荡模式之间，存在着令人费解的自由度数不匹配。我们提出了一个解决这个难题的方法，即一旦考虑α'修正，一半的弦模会溶解在两粒子态的连续谱中。我们还检查了AdS 4/CFT 3 [1]的精确S-矩阵与树级世界表计算的一致性。
The AdS4/CFT3 duality is a new example of an integrable and exactly solvable AdS/CFT system. There is, however, a puzzling mismatch between the number of degrees of freedom used in the exact solution (4B + 4F scattering states) and 8B + 8F transverse oscillation modes of critical superstring theory. We offer a resolution of this puzzle by arguing that half of the string modes dissolve in the continuum of two-particle states once α' corrections are taken into account. We also check that the conjectured exact S-matrix of AdS4/CFT3 [1] agrees with the tree-level worldsheet calculation.
