Description
Data from the p-bar12C → Λ-barΛX reaction, collected by the PS185 experiment at antiproton momenta around 1.44 GeV/c, 1.66 GeV/c and 1.77 GeV/c, have been analyzed and the Λ and Λ-bar polarisations have been extracted. The events are classified as quasi-free or non-quasi-free and it is found that the polarisations for Λ and Λ-bar differ in the latter case. Such an effect comes from differences in the interaction of the outgoing Λ and Λ-bar with the residual nucleus and the measurement constitutes the first information on Λ-bar interaction with nuclear matter
