The eikonal model for high-energy pp scattering is extended to include spin effects. The single scattering corresponds to the exchange of a flat Pomeranchukon and two (degenerate) secondary trajectories. A very simple parametrization with five arbitrary parameters is chosen. We obtain a good description of the pp data on total and differential cross-sections. the ratio of real to imaginary part of the amplitude at t = 0 and polarizations. for incident momenta between 5 and 20 GeV/c. Predictions for the\(p\bar p\) high-energy scattering, are made. They are in reasonable agreement with the experimental data and exhibit the cross over effect near the right value of the momentum transfer. Some general features of the cikonal model are also discussed.read more

TL;DR: In this paper, the triplet spin state is discussed under the following assumptions about the nuclear forces: (1) the forces are conservative, (2) they allow time-reversal, i.e., the reciprocity law is valid, and (3) the spin vectors of the neutron and proton enter in a symmetrical way, so that the total spin of the system is preserved during the collision.
