We describe the ghost sector of cubic string field theory in terms of degrees of freedom on the two halves of a split string. In particular, we represent a class of pure ghost BRST operators as operators on the space of half-string functionals. These BRST operators were postulated by Rastelli, Sen, and Zwiebach to give a description of cubic string field theory in the closed string vacuum arising from condensation of a D25-brane in the original tachyonic theory. We find a class of solutions for the ghost equations of motion using the pure ghost BRST operators. We find a vanishing action for these solutions, and discuss possible interpretations of this result. The form of the solutions we find in the pure ghost theory suggests an analogous class of solutions in the original theory on the D25-brane with BRST operator QB coupling the matter and ghost sectors.

Noncommutative field theory (2001, unknown): “Witten (2000) has shown how the noncommutative field theory and these arguments can be embedded in the framework of string field theory, and much recent progress has been made in this direction (Gross and Taylor, 2001; Rastelli, Sen and Zwiebach, 2001).”
