Differential cross section for the reaction C-12(d, p)X at a primary momentum of 9 GeV/c and its tensor and vector analyzing powers

Experimental data on the differential cross section for the reaction C-12(d, p)X at a primary momentum of 9 GeV/c and the proton emission angle of 85 mrad and on its tensor (A(yy)) and vector (A(y)) analyzing powers are presented. The differential cross section is satisfactorily described within the relativistic model of hard scattering by using conventional deuteron wave functions, while the behavior of the tensor analyzing power A(yy) which remains positive up to the maximal value of the detected-proton momentum, is at odds with the predictions of this model. Nonzero values of the vector analyzing power A(y). suggest that the spin-dependent component of the NN-scattering amplitude plays a pronounced role in the mechanism of this reaction. Data on the differential cross section and the parameters A(yy) and A(y) have also been obtained for the reaction C-12(d, d)X in the missing-mass region around 2.2 GeV/c(2).
