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−→cc⎯⎯ events produced at s√≈10.6  GeV containing both a Λ+c baryon and a Λ⎯⎯⎯−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 c⎯⎯ 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.
