Abstract

A model of a three Pomeron contribution to high energy elastic pp and p p scattering is proposed. The data are well described for all momenta (0.01≤ |t|≤ 14. GeV²) and energies (8.≤√(s)≤ 1800. GeV) (χ²/\rm d.o.f.=2.60). The model predicts the appearance of two dips in the differential cross-section which will be measured at LHC. The parameters of the Pomeron trajectories are: α(0)_\Bbb P₁=1.058, α'(0)_\Bbb P₁=0.560 (GeV^-2); α(0)_\Bbb P₂=1.167, α'(0)_\Bbb P₂=0.273 (GeV^-2); α(0)_\Bbb P₃=1.203, α'(0)_\Bbb P₃=0.094 (GeV^-2).
