$\overline{p}p\to \overline{\Lambda }\Lambda$ Reaction

The $O(3,1)\mathrm{}$ symmetry model is used to evaluate the differential cross section and spin correlations for the reaction $\overline{p}p\to \overline{\Lambda }\Lambda$ at various energies. We find fairly satisfactory agreement for the differential cross section except perhaps for the 7-GeV/c data. The spin correlations for 2.19 GeV/c are found to be qualitatively consistent with experiment.
