Abstract
We calculate the two-fermion-two-boson scattering amplitude at two loops in the NSR formalism of the heterotic and type II superstring theories by using the hyperelliptic representation of the genus 2 Riemann surface and the covariant fermion emission vertex. This computation entails the use of a modular invariant combination of a Θ-function and prime forms which we prove.
