论文摘要
我们评估了纯纺纱形式主义中封闭的弦盘振幅。我们专注于低点函数（两点和单点函数），但我们的分析也与较高的N点函数有关。除其他外，我们讨论了由于磁盘的保形杀戮组的量规固定而引起的问题，并且由于纯纺纱形式中的零模式处方。正如预期的那样，最后我们发现了与RNS形式主义的已知结果一致。
We evaluate closed string disk amplitudes in the pure spinor formalism. We focus on low point functions (two- and one-point functions) but our analysis is also relevant for higher n-point functions. Amongst others we discuss issues arising due to the gauge fixing of the conformal Killing group of the disk and due to the zero mode prescription in the pure spinor formalism. As expected, in the end we find agreement with the known results from the RNS formalism.
