Abstract:
We study the role of closed string backgrounds in boundary string field theory. Background independence requires introducing dual boundary fields, which are reminiscent of the doubled field formalism. We find a correspondence between closed string backgrounds and collective excitations of open strings described by vertex operators involving the dual fields. We discuss the renormalization group flow, solutions, and stability in an example.
Keywords:
string field theory, open–closed duality.
