The polarizations of Λ and are thought to retain memories of the spins of their parent s quarks and antiquarks, and are readily measurable via the angular distributions of their daughter protons and antiprotons. Correlations between the spins of Λ and produced at low relative momenta may therefore be used to probe the spin states of pairs produced during hadronization. We consider the possibilities that they are produced in a 3P0 state, as might result from fluctuations in the magnitude of , a 1S0 state, as might result from chiral fluctuations, or a 3S1 or other spin state, as might result from production by a quark–antiquark or gluon pair. We provide templates for the angular correlations that would be expected in each of these cases, and discuss how they might be used to distinguish production mechanisms in pp and heavy-ion collisions.
