Abstract

We have measured the rate of D^*± meson production inside the jets produced in pp collisions at √s = 630 GeV. For jets in the transverse energy range 15<E_T<60 GeV we find a production rate of 0.10±0.04±0.03 D^*± per jet, which is in good agreement with perturbative QCD calculations. In addition, we find that the D^*± fragmentation distribution is strongly peaked towards low z consistent with gluon splitting as the dominant production mechanism.
