Abstract

Based on a high statistics e e →cc̄ data sample, we report on the inclusive rate for charmed baryons to decay into Λ particles using charm-event tagging. We select e e →cc̄ events which have a clear anti-charm tag and measure the Λ content in the hemisphere opposite the tag (charge conjugate modes are implicit). This allows us to determine the product branching fraction B =B(c→Θ X)XB(Θ →ΛX), where Θ represents a sum over all charmed baryons produced in e e fragmentation at √s=10.5 GeV, given our specific tags. We obtain BΛ=(1.87±0.03±0.33)%. ©2000 The American Physical Society. + - + - + - Λ c c c
