$P\overline {P}$ Collisions

The work on $\bar{p} p$ collisions to produce hyperon-antihyperon pairs has continued. We now focus on polarization transfer and other polarization correlations in $\bar{\Lambda} \Lambda$ production. These are sensitive to small amount of spin singlet component found in the $\bar{\Lambda} \Lambda$.
