Description
A models for low missing mass M_X diffraction dissociation (DD), based on the factorization properties of the high-energy, Pomeron-exchange scattering amplitude, is constructed. The properties of the inelastic Pp-->M_X transition form factors (inelastic vertices) are those known from \gamma-p scattering at JLab, with the photon-Pomeron similarity assumed. The direct-channel, low-energy (=missing mass) baryon (protonic) trajectory is a non-linear, complex function providing for finite widths of baryon resonance lying on the protonic trajectory. The validity of finite-mass sum rules is tested, and predictions for low-mass DD cross sections at the LHC are given.
