On Finite-Size D-Branes in Superstring Theory

Abstract

We test exact marginality of the deformation describing the blow-up of a zero-size D(-1) brane bound to a background of D3-branes by analyzing the equations of motion of superstring field theory to third order in the size. In the process we review the derivation of the instanton profile from string theory, extending it to include ${\alpha }^{\prime }$- corrections.
