Observables and Correlation Functions in OSp Invariant String Field Theory
arXiv:hep-th/0703216 · doi:10.1088/1126-6708/2007/05/020
Abstract
We define BRST invariant observables in the OSp invariant closed string field theory for bosonic strings. We evaluate correlation functions of these observables and show that the S-matrix elements derived from them coincide with those of the light-cone gauge string field theory.
