Two-loop superstring five-point amplitudes. Part I. Construction via chiral splitting and pure spinors
The full two-loop amplitudes for five massless states in Type II and Heterotic superstrings are constructed in terms of convergent integrals over the genus-two moduli space of compact Riemann
Finite strings from non-chiral Mumford forms
A bstractWe show that there is an infinite class of partition functions with world-sheet metric, space-time coordinates and first order systems, that correspond to volume forms on the moduli space of
Hyperbolic Geometry of Superstring Perturbation Theory
The hyperbolic structure of the RNS formulation of perturbative superstring theory is explored, with the goal of providing a systematic method for explicitly evaluating both the on-shell and the
Two-loop superstring five-point amplitudes. Part III. Construction via the RNS formulation: even spin structures
Abstract The contribution from even spin structures to the genus-two amplitude for five massless external NS states in Type II and Heterotic superstrings is evaluated from first principles in the
Topics in Two-Loop Superstring Perturbation Theory
In this contribution to the Proceedings of the Conference on Analysis, Complex Geometry, and Mathematical Physics, an expository overview of superstring perturbation theory to two loop order is

Off-shell Amplitudes in Superstring Theory
Computing the renormalized masses and S-matrix elements in string theory, involving states whose masses are not protected from quantum corrections, requires defining off-shell amplitude with certain
Gauge invariant 1PI effective superstring field theory: inclusion of the Ramond sector
A bstractWe construct off-shell amplitudes in heterotic and type II string theories in-volving arbitrary combination of Ramond and Neveu-Schwarz sector external states. We also construct the
