Measurement of the product branching fraction B(ccX)XB(cX) Academic Article uri icon


  • Based on a high statistics e+e-cc data sample, we report on the inclusive rate for charmed baryons to decay into particles using charm-event tagging. We select e+e-cc events which have a clear anti-charm tag and measure the content in the hemisphere opposite the tag (charge conjugate modes are implicit). This allows us to determine the product branching fraction B=B(ccX)XB( cX), where c represents a sum over all charmed baryons produced in e+e- fragmentation at s=10.5 GeV, given our specific tags. We obtain B=(1.870.030.33)%. 2000 The American Physical Society.
