Abstract
We show that a partial gauge fixing of the NS sector of the democratic-picture superstring field theory leads to the non-polynomial theory. Moreover, by partially gauge fixing the Ramond sector we obtain a non-polynomial fully RNS theory at pictures 0 and \( \frac{1}{2} \). Within the democratic theory and in the partially gauge fixed theory the equations of motion of both sectors are derived from an action. We also discuss a representation of the non-polynomial theory analogous to a manifestly two-dimensional representation of WZW theory and the action of bosonic pure-gauge solutions.
We further demonstrate that one can consistently gauge fix the NS sector of the democratic theory at picture number −1. The resulting theory is new. It is a \( {\mathbb{Z}_2} \) dual of the modified cubic theory. We construct analytical solutions of this theory and show that they possess the desired properties.
