D-brane States and Disk Amplitudes in OSp Invariant Closed String Field Theory

Abstract

We construct solitonic states in the OSp invariant string field theory, which are BRST invariant in the leading order of regularization parameter $\epsilon$. We calculate the disk amplitudes using these solitonic states and show that they describe D-branes and ghost D-branes.
