Tensor Ayy and vector Ay analyzing powers in the H(d,d')X and 12C(d,d')X reactons at initial deuteron momenta of 9 GeV/c in the region of baryonic resonances excitation
Abstract
The angular dependence of the tensor Ayy and vector Ay analyzing powers in the inelastic scattering of deuterons with a momentum of 9.0 GeV/c on hydrogen and carbon have been measured. The range of measurements corresponds to the baryonic resonance excitation with masses 2.2--2.6 GeV/c2. The Ayy data being in good agreement with the previous results demonstrate an approximate t scaling up to -1.5 (GeV/c)2. The large values of Ay show a significant role of the spin-dependent part of the elementary amplitude of the NN->NN* reaction. The results of the experiment are compared with model predictions of the plane-wave impulse approximation.
