Ramond-Ramond corrections to type II supergravity at order $\alpha'^3$

TL;DR

This paper investigates the invariance of type II supergravity corrections at order α'^3 under S-duality and T-duality, focusing on Ramond-Ramond sector modifications up to field redefinition.

Contribution

It extends previous NS-NS correction results by analyzing R-R corrections at order α'^3 under duality symmetries in supergravity.

Findings

R-R corrections are consistent with duality invariances

The study identifies specific R-R terms at order α'^3

Results are up to field redefinition ambiguities

Abstract

Recently, it has been shown that the NS-NS corrections to the type II supergravity given by Gross and Sloan are invariant under the linear T-duality. In this paper, we study the invariance of this action under sequence of S-duality and linear T-duality to find the R-R corrections to the supergravity at order $\alpha'^3$, up to field redefinition.
