Abstract

A model of a three pomeron contribution to high energy elastic pp and p̄p scattering is proposed. The data are well described for all momenta (0.01 ≤ |t| ≤ 14. GeV2) and energies (8. ≤ s1/2 ≤ 1800. GeV) (Χ2/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)P1 = 1.058, α′(0)P1 = 0.560 GeV-2; α(0) P2 = 1.167, α′(0)P2 = 0.273 GeV-2; α(0)P3 = 1.203, α′(0)P3 = 0.094 GeV -2.
