D0, D+, Ds+, and Λc+ fragmentation functions from CERN LEP1 -: art. no. 094013

We present new sets of nonperturbative fragmentation functions for D-0, D+, and D-s(+) mesons as well as for Lambda(+)(c) baryons, both at leading and next-to-leading order in the (MS) over bar 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 epsilon(c) parameter, which are specific for our choice of factorization scheme.
