Tensor Ayy and vector Ay analyzing powers in the H-1(d,d ')X and C-12(d,d ')X reactions at initial deuteron momenta of 9 GeV/c in the region of baryonic resonance excitation

摘要

The angular dependence of the tensor A(yy) and vector A(y) analyzing powers in the inelastic scattering of deuterons with a momentum of 9.0 GeV/c on hydrogen and carbon has been measured. The range of measurements corresponds to the baryonic resonance excitation with masses of similar to 2.2-2.6 GeV/c(2). The A(yy) 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 A(y) 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.
