Towards the n-point one-loop superstring amplitude I: Pure spinors and superfield kinematics

10 Sep 2019 Mafra Carlos R. Schlotterer Oliver

This is the first installment of a series of three papers in which we describe a method to determine higher-point correlation functions in one-loop open-superstring amplitudes from first principles. In this first part, we exploit the synergy between the cohomological features of pure-spinor superspace and the pure-spinor zero-mode integration rules of the one-loop amplitude prescription...
