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…

Off-shell Amplitudes in Superstring Theory
