Nonlinear gauge invariance and WZW-like action for NS-NS superstring field theory

arXiv:1407.8485 · doi:10.1007/JHEP09(2015)011

Abstract

We complete the construction of a gauge-invariant action for NS-NS superstring field theory in the large Hilbert space begun in arXiv:1305.3893 by giving a closed-form expression for the action and nonlinear gauge transformations. The action has the WZW-like form and vertices are given by a pure-gauge solution of heterotic string field theory in the small Hilbert space.
