Mason和Skinner最近构造了Ramond-Neveu-施瓦茨超弦的手征无限张力极限，并证明了它可以计算d= 10的Yang-Mills振幅和NS-NS扇区的Cachazo-He-Yuan公式。本文将他们的手征无限张力极限推广到纯旋量超弦上，从而计算了d = 10的超空间Cachazo-He-Yuan公式的超空间版本d= 10的超杨-米尔斯振幅和超引力振幅。
Mason and Skinner recently constructed a chiral infinite tension limit of the Ramond-Neveu-Schwarz superstring which was shown to compute the Cachazo-He-Yuan formulae for tree-level d= 10 Yang-Mills amplitudes and the NS-NS sector of tree-level d= 10 supergravity amplitudes. In this letter, their chiral infinite tension limit is generalized to the pure spinor superstring which computes ad= 10 superspace version of the Cachazo-He-Yuan formulae for tree-level d= 10 super-Yang-Mills and supergravity amplitudes.
