Correlated Λc+Λ̄c- production in e+e- annihilations at √s∼10.5 GeV

Journal article

Using 13.6 fb-1 of continuum two-jet e+e-→cc̄ events collected with the CLEO detector, we have searched for baryon number correlations at the primary quark level. We have measured the likelihood for a Λc+ charmed baryon to be produced in the hemisphere opposite a Λc-relative to the likelihood for a Λc+ charmed baryon to be produced opposite an anticharmed meson D̄ in all cases, the reconstructed hadrons must have momentum greater than 2.3 GeV/c. We find that, given a Λc- (reconstructed in fiv...
