T-duality of curvature terms in D-brane actions

arXiv:0911.0255 · doi:10.1007/JHEP02(2010)002

Abstract

We examine the known curvature terms in the DBI part of the D-brane action under the T-duality transformation. Using the compatibility of the action with the standard rules of T-duality at the linear order as a guiding principle, we include the appropriate NS-NS -field terms in the action and show that they reproduce the O(α'^2) terms of the corresponding disk-level scattering amplitude.
