Hyperon polarisation in the reaction $p^{12}C \to \Lambda\Lambda X$
Data from the p/sup 12/C to Lambda Lambda X reaction, collected by the PS185 experiment at antiproton momenta around 1.44 GeV/c, 1.66 Ge V/c and 1.77 GeV/c, have been analyzed and the Lambda and Lambda polarisations have been extracted. The events are classified as quasi-free or non-quasi-free and i...

| description | Data from the p/sup 12/C to Lambda Lambda X reaction, collected by the PS185 experiment at antiproton momenta around 1.44 GeV/c, 1.66 Ge V/c and 1.77 GeV/c, have been analyzed and the Lambda and Lambda polarisations have been extracted. The events are classified as quasi-free or non-quasi-free and it is found that the polarisations for Lambda and Lambda differ in the latter case. Such an effect comes from differences in the interaction of the outgoing Lambda and Lambda with the residual nucleus and the measurement constitutes the first information on Lambda interaction with nuclear matter.
