Effective coupling functions extracted from the scattering experiments with polarized protons at moderate energies

Abstract

The experimental data for the polarization asymmetries of pp-scattering available at the scattering angle {theta} = 90 deg. C and at various moderate energies, as well as at E = 2.4434 GeV and various scattering angles are described by smooth phenomenological coupling functions of the form cF(q{sup 2}) [A(1 - x) + Bx], where x = [4tu/(s - 4m{sup 2})]{sup 2}, for scalar, vector, tensor and the ``magnetic moment`` couplings as well as the corresponding parity conserving axial couplings. The analysis shows a predominant role of the ``axial magnetic moment``, the axial scalar, and the axial vector interactions. Moreover, the data contain oscillations of the type sin (q{omega}{sub 0} - {pi})/(q{omega}{sub 0} - {pi}), where q is the square root of the energy-momentum transfer. The oscillations have amplitudes of 5%, and a constant frequency {omega}{sub 0} = 2{pi}/0.88 m{sub p}. They arise from oscillating modulations up to 25% of the non-axial coupling functions.
