Abstract
We present a study of 649±35 e+e-→cc̅ events produced at √s≈10.6 GeV containing both a Λc+ baryon and a Λ̅ c- antibaryon. The number observed is roughly 4 times that expected if the leading charmed hadron types are uncorrelated, confirming an observation by the CLEO Collaboration. We find a 2-jet topology in these events but very few additional baryons, demonstrating that the primary c and c̅ are predominantly contained in a correlated baryon-antibaryon system. In addition to the charmed baryons we observe on average 2.6±0.2 charged intermediate mesons, predominantly pions, carrying 65% of the remaining energy.
