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… Expand

We develop an efficient recursive method to evaluate the tachyon potential using the relevant universal subalgebra of the open string star algebra. This method, using off-shell versions of Virasoro… Expand

A detailed quantitative calculation is carried out of the tunneling process described by the Belavin-PolyakovSchwarz-Tyupkin field configuration. A certain chiral symmetry is violated as a… Expand
