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