Supersymmetric dual string theory (II). Vertices and trees
Abstract
Vertex operators for the emission of massless open-string states are constructed using the light-cone gauge formalism introduced in the first paper of this series. The vertices for vector and spinor emission transform into one another under supersymmetry in the same way as the states themselves. This enables one to construct amplitudes and deduce the relationships among them implied by supersymmetry. Various four-particle tree graphs are explicitly investigated and shown to satisfy the duality requirement.
