Super-Poincare Covariant Two-Loop Superstring Amplitudes

Abstract

The super-Poincare covariant formalism for the superstring is used to compute massless four-point two-loop amplitudes in ten-dimensional superspace. The computations are much simpler than in the RNS formalism and include both external bosons and fermions.
