Is there a hadron spin-flip contribution to the Coulomb-hadron interference at small momentum transfer and high energies?

摘要

The analysing power A(N) is examined in the range of the Coulomb-hadron interference on the basis of the experimental data from p(L) = 6 GeV/c up to 200 GeV/c taking account of a phenomenological analysis at p(L) = 6 GeV/c and a dynamic high-energy spin model. The results are compared with the new RHIC data at p(L) = 100 GeV/c. The new experimental data obtained at RHIC indicate small contributions of the hadron spin-flip amplitude.
