Charmed-hadron fragmentation functions from CERN LEP1 revisited

Abstract

In Phys. Rev. D 58, 014014 (1998) and 71, 094013 (2005), we determined nonperturbative ${D}^{0}$, ${D}^{+}$, ${D}^{*+}$, ${D}_{s}^{+}$, and ${\ensuremath{\Lambda}}_{c}^{+}$ fragmentation functions, both at leading and next-to-leading order in the $\overline{\mathrm{MS}}$ factorization scheme, by fitting ${e}^{+}{e}^{\ensuremath{-}}$ data taken by the OPAL Collaboration at CERN LEP1. The starting points for the evolution in the factorization scale $\ensuremath{\mu}$ were taken to be ${\ensuremath{\mu}}_{0}=2{m}_{Q}$, where $Q=c$, $b$. For the reader's convenience, in this paper, we repeat this analysis for ${\ensuremath{\mu}}_{0}={m}_{Q}$, where the flavor thresholds of modern sets of parton density functions are located.
