Updated charm fragmentation probabilities

Abstract

The world average values for the probabilities that a charm quark fragments into D^*+ and Ds^+ have been calculated to be f(c->D^*+)=0.235+/-0.007(+/-0.007) and f(c->Ds^+)=0.101+/-0.009(+/-0.025), respectively. The average values for D^0, D^+ and Lambda_c^+ have been also calculated.
