Tree-level amplitudes from the pure spinor superstring

High Energy Physics - Theory 2023-05-24 v2

Abstract

We give a comprehensive review of recent developments on using the pure spinor formalism to compute massless superstring scattering amplitudes at tree level. The main results of the pure spinor computations are placed into the context of related topics including the color-kinematics duality in field theory and the mathematical structure of α\alpha'-corrections.
