Superstring Perturbation Theory Revisited
Abstract:
Perturbative superstring theory is revisited, with the goal of giving a simpler
and more direct demonstration that multi-loop amplitudes are gauge-invariant (apart from
known anomalies), satisfy space-time supersymmetry when expected, and have the ex-
pected infrared behavior. The main technical tool is to make the whole analysis, including
especially those arguments that involve integration by parts, on supermoduli space, rather
than after descending to ordinary moduli space.
Supplements of this paper are:
Notes On Super Riemann Surfaces And Their Moduli
Abstract:
These are notes on the theory of super Riemann surfaces and their moduli
spaces, aiming to collect results that are useful for a better understanding of superstring
perturbation theory in the RNS formalism.
Notes On Supermanifolds and Integration
Abstract:
These are notes on the theory of supermanifolds and integration on them, aiming to collect results that are useful for a better understanding of superstring perturbation theory in the RNS formalism.
