我们证明了纯旋量形式中的2点树振幅是有限的，并且等于场论中的相应表达式。在[arXiv:1906.06051v1-arXiv:1909.03672v3]中，对玻色子弦给出了相同的结果，并提到它们可以推广到超弦。纯旋量形式论是超弦量子化的一个成功的超庞加莱协变方法[j]。因为纯旋量形式与其他超弦形式是等价的，所以我们明确地验证了上面的说法。为了实现这一目标，我们引入了一个主要是BRST的精确算子。
We show that the 2 point tree amplitudes in the pure spinor formalism are finite and equal to 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 successfull super-Poincare covariant approach to quantizing 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.
