Two-loop superstring five-point amplitudes. Part I. Construction via chiral splitting and pure spinors

- Mathematics
- 2020

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

- Mathematics
- 2012

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

- Physics
- 2017

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

- PhysicsJournal of High Energy Physics

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…

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

- Physics
- 2018

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
