Large Rapidity Gap Method to Select Soft Diffraction Dissociation at the LHC

Figure 3

The relation between the size of the large rapidity gap, , and for SDD events. The gap is defined as an edge gap. (a) Whole pseudorapidity range is used without any transverse momentum () threshold on particles. (b) For particles within without any threshold. (c) For particles within with 200 MeV.
