Classical solution for ghost D-branes in string field theory

Published 3 Apr 2017 in hep-th | (1704.00564v2)

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.
