Correlated inclusive / production in e+e- annihilations at sqrt(s)~10.5 GeV
The CLEO Collaboration
Abstract
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 / 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 // correlations indicated direct, associated production of primary charmed baryons /: e+e- -> ccbar -> //. 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 -> /, e.g.) qualitatively indicates a similar effect, although it relies on a Monte Carlo dependent subtraction of background / production (based on the default JETSET 7.4 event generator).
