Abstract
A set of conditions expressing tree-level unitarity in the theory of open superstrings has recently been formulated by Schwarz. His conjecture that the Yang-Mills gauge group must be a classical group, with the massless particles in the adjoint representation, is proved in detail. It is also shown how the representations of the massive states are classified in each one.File in questo prodotto:
