Classical solution for ghost D-branes in string field theory
arXiv:1704.00564 · doi:10.1155/2017/8313109
Abstract
A ghost D-brane has been proposed as an object that cancels the effects of a D-branes. We construct a classical solution with an arbitrary number of D-branes and ghost D-branes in the context of open string field theory. Cancellation of BRST cohomolgy between D-branes and ghost D-branes is shown.
