Correlated leading baryon-antibaryon production in e(+)e(-) -> c(c)over-bar -> Lambda(+)(c)(Lambda)over-bar(c)(-)X

We present a study of 649±35 e⊃+e⊃-→cc̄ events produced at √s±10.6GeV containing both a Λc+ baryon and a Λ̄c- 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 to...
