Charmed-quark fragmentation into charmed hadrons

We show that in a model where fragmentation functions are created from jet calculus followed by recombination, the fragmentation function of charmed quarks into D mesons will fail to peak at low x at currently accessible values of Q2. Likewise, the fragmentation of a c quark into a Λ/sub c/ is much less peaked toward small x than the production of protons by u quarks. The model predicts a magnitude for the fragmentation function much smaller than is experimentally observed
