[en] Various spin observables (analyzing powers and spin-correlation parameters) in pd elastic scattering at T=800-1000 MeV are analyzed within the framework of the refined Glauber model. The theoretical model uses as input spin-dependent NN amplitudes obtained from the most recent partial-wave analysis and also takes into account the deuteron D wave and charge-exchange effects. Predictions of the refined Glauber model are compared with the existing experimental data. Reasonable agreement between the theoretical calculations and experimental data at low momentum transfers |t|≲0.2 (GeV/c) is found for all observables considered. Moderate discrepancies found in this region are shown to be likely due to uncertainties in the input NN amplitudes. Qualitative agreement at higher momentum transfers is also found for most observables except the tensor ones with mixed x and z polarization components. Possible reasons for observed deviations of the model calculations from the data at |t|>0.2 (GeV/c) are discussed.
