# A ∞ /L ∞ structure and alternative action for WZW-like superstring field theory

Journal of High Energy Physics, Jan 2017

We propose new gauge invariant actions for open NS, heterotic NS, and closed NS-NS superstring field theories. They are based on the large Hilbert space, and have Wess-Zumino-Witten-like expressions which are the $${\mathrm{\mathbb{Z}}}_2$$-reversed versions of the conventional WZW-like actions. On the basis of the procedure proposed in arXiv:​1505.​01659, we show that our new WZW-like actions are completely equivalent to A ∞ /L ∞ actions proposed in arXiv:​1403.​0940 respectively.
