T-duality of the Riemann curvature corrections to supergravity

arXiv:1208.4459 · doi:10.1016/j.physletb.2012.12.012

Abstract

We examine the known Riemann curvature corrections to the supergravity action at order under the T-duality transformations. Using the compatibility of the action with the linear T-duality and with the S-matrix calculations as guiding principles, we have found the couplings of four -field strengths and the couplings of two Riemann curvatures and two -field strengths at order . Using the S-matrix calculations we have also found new dilaton couplings in the string frame at this order.
