The three-component dual deck model,factorization and double diffractive dissociation

We propose the generalization to double diffractive dissociation (DDD) of the three-component dual Deck model which was designed to describe single diffractive dissociation and successfully applied to N → Nπ dissociation. With no free parameter we get a very satisfactory agreement with the existing data in nn → (pπ^?)(pπ^?) including the observed pronounced structure in the momentum transfer distributions. We also predict unexpected correlations between the cos θ_J of the two decays, which, through factorization are typical of our three-component dual Deck model. A general discussion of factorization properties is given.
