We describe projection operators in the matter sector of Witten's cubicstring field theory using modes on the right and left halves of the string.These projection operators represent a step towards an analytic solution of theequations of motion of the full string field theory, and can be used toconstruct Dp-brane solutions of the string field theory when the BRST operatorQ is taken to be pure ghost, as suggested in the recent conjecture by Rastelli,Sen and Zwiebach. We show that a family of solutions related to the sliverstate are rank one projection operators on the appropriate space of half-stringfunctionals, and we construct higher rank projection operators corresponding toconfigurations of multiple D-branes.Comment: 23 pages, Latex; v2: references added, typos fixed, footnote adde
