Abstract
The polarization of the protons emerging at 0$\sp\circ$ from the inclusive deuteron breakup reaction $\sp1$H($\vec d,\vec p$)X was measured using a deuteron beam with kinetic energy of 2.1 GeV. The momentum of the protons was selected by the magnetic spectrometer SPES4 and the polarization was measured with the polarimeter POMME. This experiment was performed at eight different proton momenta. When those momenta are Lorentz transformed to the deuteron rest frame, they corresponded to values from 0.00 to 0.34 GeV/c. The result of the measurements is expressed in terms of polarization transfer coefficient which is defined as the ratio of the measured proton polarization $P\sb{p}$ to the deuteron beam vector polarization $P\sb{Z}\:\kappa\sb{o} = P\sb{p}/P\sb{Z}.$ The values of $\kappa\sb{o}$ decreased from 0.995 to $-$0.320 across the proton momentum range of this experiment. The trend of $\kappa\sb{o}$ is in general agreement with the expected behavior arising from the D state in the deuteron wave function. The impulse approximation predicts quite well the general shape of $\kappa\sb{o}.$ Multiple scattering and relativistic effect based on different models of reaction mechanism are discussed.
