Diffraction dissociation in proton?proton collisions at \sqrt{s} = 0.9, 2.76 and 7 TeV with ALICE at the LHC

The relative rates of single- and double-diffractive processes were measured with the ALICE detector by studying properties of gaps in the pseudorapidity distribution of particles produced in proton?proton collisions at = 0.9, 2.76 and 7 TeV. ALICE triggering efficiencies are determined for various classes of events using a detector simulation validated with data on inclusive particle production. Cross-sections are determined using the van der Meer scans to measure beam properties and obtain a measurement of the luminosity.

Predictions of the Quark–Gluon String Model for pp at LHC

The Model of Quark–Gluon Strings is used for describing particle production at high energies. Cross-sections of large-mass diffractive production are described by the reggeon model where all legs of triple-reggeon and loop diagrams are eikonalized. Numerical calculation shows that this approach gives a very good description of available S
