Low missing mass, single- and double diffraction dissociation at the LHC

Understand

Low missing mass, single- and double diffraction dissociation is calculated for the LHC energies from a dual-Regge model, dominated by a Pomeron Regge pole exchange.

• The model reproduces the rich resonance structure in the low missing mass Mx region.
• The diffractionly excited states lie on the nucleon trajectory, appended by the isolated Roper resonance.
• Detailed predictions for the squared momentum transfer and missing mass dependence of the differential and integrated single- and double diffraction dissociation in the kinematical range of present and future LHC measurements are given.
