The high-energy hadron spin-flip amplitude at small momentum transfer and new AN data from RHIC
In the case of elastic high-energy hadron-hadron scattering, the impact of the largedistance contributions on the behaviour of the slopes of the spin-non-flip and of the spinflip amplitudes is analysed. It is shown that the long tail of the hadronic potential in impact parameter space leads to a value of the slope of the reduced spin-flip amplitude larger than that of the spin-non-flip amplitud...
متن کاملSpin-flip Amplitude of Hadron Elastic Scattering and Possible Polarization Effects at RHIC
With relation to the RHIC spin programwe research the polarization effects in elastic proton-proton scattering at small momentum transfer and in the diffraction dip region. The calculations take into account the Coulomb-hadron interference effects including the additional Coulomb-hadron phase. In particular we show the impact of the form of the hadron potential at large distances on the behavio...
متن کاملHadron spin-flip amplitude: an analysis of the new AN data from RHIC
Through a direct analysis of the scattering amplitude, we show that the preliminary measurement of AN obtained by the E950 Collaboration at different energies are mainly sensitive to the spin-flip part of the amplitude in which the proton scatters with the 12C nucleus as a whole. The imaginary part of this amplitude is negative, and the real part positive. We give predictions for pL = 600 GeV/c...
متن کاملHigh - energy spin effects and structure of elastic scattering amplitude
A behavior of imaginary and real parts of the high-energy elastic hadron scattering amplitude is examined in the diffraction region. It is shown that the interference between Coulomb and hadronic scattering at small momentum transfers and especially in the region of diffractive minimum can bring some information about the structure of the hadron spin-non-flip amplitude.
متن کاملIs there a hadron spin-flip contribution to the Coulomb-hadron interference at small transfer momenta and high energies
The analysing power AN is examined in the range of the Coulomb-hadron interference on the basis of the experimental data from pL = 6 GeV/c up to 200 GeV/c taking account of a phenomenological analysis at pL = 6 GeV/c and a dynamic high-energy spin model. The results are compared with the new RHIC data at pL = 100 GeV/c. The new experimental data obtained at RHIC indicate small contributions of ...
