We present a study of leading protons and antiprotons in p-nucleus and $$\bar p$$ -nucleus on Be, Cu, Ag, W, and U targets. The experiment was performed at the CERN-SPS at a beam energy of 120 GeV. For all targets a suppression of secondary antiprotons with respect to protons is observed. The difference between the $$\bar p$$ and p spectra increases with decreasing χ-values and the effect is stronger for heavier nuclei. The features of the data are qualitatively consistent with multiple-collisions modesls. The data are analysed in terms of a dual parton model which gives a satisfactory description of leading p and $$\bar p$$ spectra. [ABSTRACT FROM AUTHOR] |
