Gribov-Regge Pomeron and hadron structure phenomenology at high energy

Pomeron was introduced as a key object which provides the non-vanishing high energy asymptotic of the total cross sections of strong interactions. The universality of this object was observed first in the studies of the elastic cross sections t-slope shrinkage. Besides the one Pomeron exchange,the unitarity generates more complicated multi-Pomeron contributions which, in particular, describe the diffractive dip structure of the differential 2→2 cross sections at a larger t. Somewhat unexpected universal features of Bose-Einstein correlations reported in the studies of inelastic events at CERN hadron colliders (ISR, Spp̄S) are naturally explained within the Pomeron approach. Large Hadron Collider (LHC) opens the possibility to investigate such phenomena in more details and with a high precision.
