Factorization of bosonic string scattering amplitudes
- 1. Hamburg Univ. (Germany, F.R.). 2. Inst. fuer Theoretische Physik
Description
In an off-shell formulation, where scattering amplitudes for closed bosonic strings are defined as Polyakov path integrals over bordered world sheets, factorization of the amplitudes at the poles of exchanged particle states is shown in any order of perturbation theory. The same factorization is obtained for amplitudes defined via vertex operators, again for any number of loops. (orig.)
