We compute the tree-level H2R3 couplings of type II strings and provide some basic tests of the couplings by considering both K3 and Calabi-Yau threefold compactifications. Curiously, additional kinematical structures show up at tree level that are not present in the one-loop couplings. This has interesting implications for type II supersymmetry as well as SL(2,Z) duality in type IIB strings.

弦论中的高阶导数耦合:五点接触项

我们计算树级 H2个[R3通过考虑K3和Calabi-Yau三重压实,提供了II型琴弦的联轴器,并提供了一些基本的联轴器测试。奇怪的是,其他运动学结构在树级别显示出来,而这些结构在单回路耦合中不存在。这对于II型超对称以及小号大号2个ž IIB类型字符串中的对偶性。
