Covariant Quantization and the Three-Reggeon Vertex

We review the old covariant quantization by writing the equations, that characterize the physical states and their vertex operators. These equations are explicitly solved by constructing the most general physical state together with the corresponding vertex operator, that is then used to construct the interaction term used in the light-cone string field theory. Finally we construct an extension of the Sciuto Vertex, that includes the ghost coordinates and that is invariant under BRST transformations.
