Study of polarized proton-proton elastic scattering in the Coulomb-nuclear interference region allows one to measure the forward hadronic single spin-flip amplitude including its phase. However, in a precision experimental data analysis, a phase shift correction δ C due to the long distance Coulomb interaction should be taken into account. For unpolarized scattering, δ C is commonly considered as well established. Here, we evaluate the Coulomb phase shifts for the forward elastic proton-proton single spin-flip electromagnetic and hadronic amplitudes. Only a small discrepancy between the spin-flip and non-flip phases was found which can be neglected in the high energy forward elastic pp studies involving transverse spin. Nonetheless, the effective alteration of the hadronic spin-flip amplitude by the long distance electromagnetic corrections can be essential for interpretation of the experimental results.

“…Secondly, these measurements were made at low and middle energies. Nevertheless, the available data stimulate permanently the theoretical and phenomenological studies of spin phenomena in the regions of soft and hard kinematic were different approaches (nonperturbative approches from early [11] to relatively later and recent [6,[12][13][14][15], and perturbative QCD) are exploring [16].…”

We assume that the scattering amplitude is represented by Froissaron, Maximal Odderon as well as by standard Regge poles. From the fit to the data of pp and pp 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, but also the existing experimental data on polarization.
