Abstract

In this work we derive two important tools for working in the κbasis of string field theory. First we give an analytical expression for the finite part of the spectral density ρ_fin. This expression is relevant when both matter and ghost sectors are considered. Then we calculate the form of the matter part of the Virasoro generators L_n in the κbasis, which construct string field theory's derivation Q_BRST. We find that the Virasoro generators are given by one dimensional delta functions with complex arguments.
