论文摘要
我们提供了一个处方，用于计算纯纺纱形式主义中的两点树振幅，该形式是有限的，并且与现场理论中的相应表达式一致。在[Arxiv：1906.06051v1-arxiv：1909.03672v3]中，给出了相同的剂量结果，并提到可以将它们推广到超链。纯纺纱形式主义是一种成功的超级铅协变量方法，用于量化超弦[arxiv：hep-th/0001035v2]。由于纯旋子形式主义等于其他超弦形式，因此我们明确验证了上述主张。我们介绍了一个大多数BRST精确的操作员，以实现这一目标。
We provide a prescription for computing two-point tree amplitudes in the pure spinor formalism that are finite and agree with the corresponding expression in the field theories. In [arXiv:1906.06051v1-arXiv:1909.03672v3], same results were presented for bosonic strings and it was mentioned they can be generalized to superstrings. The pure spinor formalism is a successful super-Poincare covariant approach to quantization of superstrings [arXiv:hep-th/0001035v2]. Because the pure spinor formalism is equivalent to other superstring formalisms, we explicitly verify the above claim. We introduce a mostly BRST exact operator in order to achieve this.
