Abstract: (Springer)
We propose a form for a dual resonant amplitude withN nonspurious excited particles in which both duality and factorization are explicitly exhibited. The expression, obtained by writing the amplitude as an expectation value of a product ofN operators covariant under the projective group, enjoys the same properties as the standardN-point generalized Veneziano function for ground-state particles.
