Abstract

The scattering amplitude with spin-non-fiip and spin-flip components represented by Froissaron, Maximal Odderon as well as by standard Regge poles contributions is considered. From the fit to the data of pp and $\bar{p} p$ $\bar{p}p$ scattering at high energy and not too large momentum transfers we found that this model taking into account the spin is available to describe not only the differential, total cross section and $ρ$ $\rho$ , but also the existing experimental data on polarization. It allows to make some predictions about spin effects at high energies.
