Correlated inclusive /\bar production in e+e- annihilations at   sqrt(s)~10.5 GeV
  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).
