Abstract
Using the explicit string scattering calculation and the linear T-dual ward identity, we evaluate the string theory disc amplitude of one Ramond-Ramond field and two Neveu-Schwarz B-fields in the presence of a single -brane in type string theory. From this amplitude we extract the (or equivalently four-derivative) part of the -brane couplings involving these fields.
