我们为开超弦场论构造了一个完整的作用量,它包含了Neveu-Schwarz扇区和Ramond扇区。对于Neveu-Schwarz扇区,我们使用超共形鬼扇区的大希尔伯特空间中的弦场,并且Neveu-Schwarz扇区中的作用量与Berkovits公式中的Wess-Zumino-Witten-like作用量相同。对于Ramond扇区,已知在小希尔伯特空间的适当子空间上的BRST上同调再现了正确的谱,并且我们使用投影到该子空间的弦场。我们表明,该行动是不变的规范下的变换是一致的投影弦领域的拉蒙部门。
We construct a complete action for open superstring field theory that includes the Neveu–Schwarz sector and the Ramond sector. For the Neveu–Schwarz sector, we use the string field in the large Hilbert space of the superconformal ghost sector, and the action in the Neveu–Schwarz sector is the same as the Wess–Zumino–Witten-like action of the Berkovits formulation. For the Ramond sector, it is known that the BRST cohomology on an appropriate subspace of the small Hilbert space reproduces the correct spectrum, and we use the string field projected to this subspace. We show that the action is invariant under gauge transformations that are consistent with the projection for the string field in the Ramond sector.
