Type II superstring field theory revisited

TL;DR

This paper reconstructs a complete type II superstring field theory with an L-infinity structure, demonstrating its consistency with known S-matrix results and connecting it to a yet-to-be-constructed WZW-like formulation.

Contribution

It provides a symmetric reconstruction of type II superstring field theory with L-infinity structure and links it to the WZW-like superstring field theory.

Findings

Tree-level S-matrix matches first-quantization results.

Reconstruction enables mapping to WZW-like superstring field theory.

Fills gap in the WZW-like formulation.

Abstract

We reconstruct a complete type II superstring field theory with L-infinity 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.
