A note on the quartic effective action of type IIB superstring

arXiv:0812.3138 · doi:10.1088/0264-9381/26/12/125001

Abstract

We recast the result of our recent computation of the quartic action of ten-dimensional IIB supergravity in a manifestly SL(2,R)-covariant form. This affords us a critical assessment of an earlier conjecture in the literature.
