最近的分歧的背景下,广告/CFT的动机,我们研究的非平面部门的BMN对应。特别是,我们重新考虑光锥弦场论中两个弦激发态的能量转移,并明确确定其完整的微扰贡献的杂质守恒通道。令人惊讶的是,我们的结果既不同意较早的领先阶计算,也不再现规范理论的预测。不仅如此,它还具有有效规范耦合λ′的半整数幂,这代表了与规范理论的质的差异。基于超对称性,我们认为,上述截断是不适合的结论性测试的BMN对偶。
Motivated by recent disagreements in the context of AdS/CFT, we study the non-planar sector of the BMN correspondence. In particular, we reconsider the energy shift of states with two stringy excitations in light-cone string field theory and explicitly determine its complete perturbative contribution from the impurity-conserving channel. Surprisingly, our result neither agrees with earlier leading order computations, nor reproduces the gauge theory prediction. More than that, it features half-integer powers of the effective gauge coupling λ′representing a qualitative difference to gauge theory. Based on supersymmetry we argue that the above truncation is not suited for conclusive tests of the BMN duality.
