Type II superstring field theory revisited

Abstract

We reconstruct a complete type II superstring field theory with L ∞ structure in a symmetric way concerning the left-and right-moving sectors. Based on the new construction, we show again that the tree-level S-matrix agrees with that obtained using the first-quantization method. Not only is this a simple and elegant reconstruction, but it also enables the action to be mapped to that in the WZW-like superstring field theory, which has not yet been constructed and fills the only gap in the WZW-like formulation.
