Two-Loop Computation in Superstring Theory

High Energy Physics - Theory 2007-05-23 v1

Abstract

In this paper I review some old and new works on the computation of two-loop 4-particle amplitude in superstring theory. I also present the proof by Iengo, showing the vanishing of the term related to the two-loop correction to the R4R^4 term. Finally I will present some recent works on two-loop computation in hyperelliptic language following the new gauging fixing method of D'Hoker and Phong.
