Correlated inclusive $\Lambda \overline{\Lambda }$ production in $e^{+}{e}^{-}$ annihilations at $\sqrt{s}\sim 10.5\mathrm{GeV}$

Using a $13.7{\mathrm{fb}}^{-1}$ sample of continuum two-jet $e^{+}{e}^{-}\to q\overline{q}$ events collected with the CLEO detector, we have searched for correlations between Λ and $\overline{\Lambda }$ particles, specifically in cases where the opening angle between the two particles is large and each has momentum $>1\mathrm{}\mathrm{GeV}/c.\mathrm{}$ Such correlations may indicate the presence of baryon number conservation at the primary quark level. A previous CLEO study of ${\Lambda }_c{\overline{\Lambda }}_c$ correlations indicated direct, associated production of primary charmed baryons ${\Lambda }_c:$ $e^{+}{e}^{-}\to c\overline{c}\to {\Lambda }_c{\overline{\Lambda }}_c.$ That effect was not observed in Monte Carlo simulations. Our current search for similar direct, associated production of Λ baryons at the primary quark level ${(e}^{+}{e}^{-}\to s\overline{s}\to \Lambda \overline{\Lambda },$ e.g.) qualitatively indicates a similar effect, although it relies on a Monte Carlo dependent subtraction of background $\Lambda \overline{\Lambda }$ production (based on the default JETSET 7.4 event generator).
