Abstract: (Elsevier)
The Polyakov integral with boundaries can be used to provide a propagator for the second-quantized bosonic string. This propagator makes sense off-shell. For special initial and final states we compute it explicitly in the tree approximation, where it reduces to the correct sum of field theoretic particle propagators.- MODEL: STRING
