Abstract

We present new sets of nonperturbative fragmentation functions for $D^{0}$ , $D^{+}$ , and $D_{s}^{+}$ mesons as well as for $Λ_{c}^{+}$ baryons, both at leading and next-to-leading order in the $\bar{MS}$ factorization scheme with five massless quark flavors. They are determined by fitting data of $e^{+} e^{-}$ annihilation taken by the OPAL Collaboration at CERN LEP1. We take the charm-quark fragmentation function to be of the form proposed by Peterson et al. and thus obtain new values of the $ϵ_{c}$ parameter, which are specific for our choice of factorization scheme.
