Open superstring field theory admits a “hybrid” formulation where N = 1 D = 4 supersymmetry is manifest for Calabi-Yau compactifications to four dimensions. Using this formulation, the half-BPS instanton solution of four-dimensional super-YangMills can be easily generalized to the full open superstring field theory. In this paper, we compute the first stringy correction to the super-Yang-Mills instanton solution which involves turning on certain fields at the first massive level.

Using string field theory, we argue that the tachyon potential on a D-brane in bosonic string theory in arbitrary background has a universal form, independent of the boundary conformal field theory…
