Study of flavor-tagged baryon production in $B$ decay

Using data collected on the ${\rm Y}\mathrm{}\left(4S\right)\mathrm{}$ resonance and the nearby continuum by the CLEO-II detector, we have studied combinations of baryons with leptons produced in the process ${\rm Y}\mathrm{}\left(4S\right)\mathrm{}\to B\overline{B}$, $B\to \mathrm{lepton}+X$, $\overline{B}\to \mathrm{baryon}+X$. Our results do not support models which attribute the bulk of ${\Lambda }_c$ production in $\overline{B}$ decay to the process $b\to {\mathrm{cW}}^{-}{,W}^{-}\to \overline{c}s$.
