Baryon production and the charmed-quark fragmentation function

Abstract

The fragmentation function for a charmed quark into a charmed baryon should peak at large $x$ like its fragmentation function for charmed mesons. With model assumptions the decay of these fast baryons can account for as much as 20 to 40% of the $\Lambda \text{'}\mathrm{s}$ observed at large $x$ in $e^{+}{e}^{-}$ annihilation at $E_{\mathrm{c}.\mathrm{m}.\mathrm{}}=30\mathrm{}$ GeV.
