论文摘要
我们研究了IIB型的非线性结构，涉及度量标准和复杂化的三型$ G_3 $的八源耦合。我们表明，在五点字符串幅度的水平上，最大的R-与对称竞争扇区中的运动学完全与标准的SuperSpace积分完全匹配，并且在两端的Mhewore中，Mewory中的SuperPresticle振幅。后一种方法用于确定该部门的完整有效措施，并在SL $（2，\ Mathbb {Z}）$ duality下验证其不变性。我们进一步评论更高点运动学的一般结构。较低维度的压缩为我们的结果和应用程序的竞技场提供了两种测试。我们验证K3降低与六维超对称的约束完全一致，并以$（α^{\ prime}）^calabi-yau-yau-yau-yau-yau三倍减少的顺序以$ $（α^{\ prime}）的顺序得出了四维通量标量势和轴心动力学项。
We study the non-linear structure of Type IIB eight-derivative couplings involving the metric and the complexified three-form $G_3$. We show that, at the level of five-point string amplitudes, the kinematics in the maximally R-symmetry-violating sector is fully matched by standard superspace integrals and by superparticle amplitudes in M-theory on a two-torus. The latter approach is used to determine the complete effective action in this sector and to verify its invariance under SL$(2,\mathbb{Z})$ duality. We further comment on the general structure of the higher-point kinematics. Compactifications to lower dimensions provide both tests for our results and the arena for their applications. We verify that K3 reductions are fully consistent with the constraints of six-dimensional supersymmetry, and derive the four-dimensional flux scalar potential and axion kinetic terms at order $(α^{\prime})^{3}$ in Calabi-Yau threefold reductions.
