我们考虑了最大超对称pp波背景下的IIB型弦相互作用,讨论了背景的玻色对称性是如何实现的。这个分析表明,有一些有趣的差异,相对于平坦空间的情况下,并建议修改现有形式的弦顶点。我们专注于零模式的一部分,这是负责一些令人费解的字符串预测的超级杨米尔斯的一面。我们发现,这些难题消失时,对称性保持字符串相互作用。
We consider type IIB string interaction on the maximally supersymmetric pp-wave background and discuss how the bosonic symmetries of the background are realized. This analysis shows that there are some interesting differences with respect to the flat-space case and suggests modifications to the existing form of the string vertex. We focus on the zero-mode part which is responsible for some puzzling string predictions about the super Yang–Mills side. We show that these puzzles disappear when a symmetry preserving string interaction is used.
