Tensor Analyzing Power AYY in Deuteron Inclusive Breakup at Large PT and Spin Structure of the Deuteron at Short Internucleonic Distances

A_yy data for deuteron inclusive breakup of hydrogen and carbon at a deuteron momentum of 9.0 GeV/c and large p_T of emitted protons are presented. The large values of A_yy independent of the target mass reflect the sensitivity of the data to the deuteron spin structure. The data obtained at fixed x and plotted versus P_t clearly demonstrate the dependence of the deuteron spin structure at short internucleonic distances on two variables. The data are compared with the calculations using Paris, CD-Bonn and Karmanov's deuteron wave functions.
