Abstract

We formulate a string field theory for open N=2\mathcal{N}=2 strings with an AA_{\infty} algebra structure. Starting from the BRST cohomology relative to the U(1) anti-ghost zero-mode, we generalize [arXiv:1312.2948] and constructed all interacting vertices recursively and without singularity. We also show that our string field theory reproduces the correct perturbative S-matrix.
