论文摘要
我们重新考虑了IIB型IIB Erientifold SuperString理论的无质量Neveu-Schwarz-Neveu-Schwarz的两点弦散射幅度，该状态在十个维度上的磁盘和投影平面上，并分析其$α''''$扩展。我们还讨论了关于$ T^6/\ Mathbb {Z} _2 \ times \ Mathbb {z} _2 $的无方向性IIB理论，其中在disk和Provendive blandive上计算了复杂的KählerOduli和复杂扇区的复杂结构的两个点字符串散射幅度。与已知结果一起获得了新的结果。最后，我们将$α'^2 $ order的弦散射振幅结果与（曲率）$^2 $术语在两种情况下的低能效果和$ω$平面中的（曲率）$^2 $项中进行了比较。
We reconsider the two-point string scattering amplitudes of massless Neveu-Schwarz--Neveu-Schwarz states of Type IIB orientifold superstring theory on the disk and projective plane in ten dimensions and analyse its $α'$ expansion. We also discuss the unoriented Type IIB theory on $T^6/\mathbb{Z}_2\times\mathbb{Z}_2$ where two-point string scattering amplitudes of the complex Kähler moduli and complex structures of the untwisted sector are computed on the disk and projective plane. New results are obtained together with known ones. Finally, we compare string scattering amplitudes results at $α'^2$-order with the (curvature)$^2$ terms in the low energy effective action of D-branes and $Ω$-planes in both cases.
