Towards one-loop SYM amplitudes from the pure spinor BRST cohomology
Towards one-loop SYM amplitudes from the pure spinor BRST cohomology
In this paper, we outline a method to compute supersymmetric one-loop integrands in ten-dimensional SYM theory. It relies on the constructive interplay between their cubic-graph organization and BRST invariance of the underlying pure spinor superstring description. The five- and six-point amplitudes are presented in a manifestly local form where the …
