Abstract
The gauge-fixed action of a "spacetime-filling" D3-brane with dilaton-axion coupling is formulated in N = 1 superspace. We investigate its symmetries by paying special attention to a possible nonlinearly realized extra supersymmetry, and emphasize the need of a linear superfield coupled to an Abelian Chern-Simons superfield to represent a dilaton-axion supermultiplet in the off-shell manifestly supersymmetric approach.
