The Pomeron spin-flip and its measurements
Original language description
We investigate the spin-flip component of the Pomeron using the single spin asymmetry, AN(t) in polarized elastic pp scattering, arising from Coulomb-nuclear interference (CNI) in small-angle elastic scattering.The previous analyses have missed the absorptive corrections to the Coulomb amplitude of pp elastic scattering, which plays an important role. Namely, interference of ultra-peripheral and central collisions leads to significant changes in AN(t).We found that the absorptive corrections considerably affect the results of the analysis of the single spin asymmetry data fromSTAR data for AN(t) at sroot =200 GeV. At such high energy, the Reggeon contribution is expected to be small so that one can study the Pomeron spin-flip component.
