| Abstract: | Using conformal mapping techniques, we obtain a new BRST invariant operator ϒ encoding in closed form transition amplitudes between open strings and closed strings. The residues of the closed string poles in the non-planar one-loop two-point diagram of Witten's string field theory are finite sums of products of these amplitudes. |
