On the quark distribution in an on-shell heavy quark and its all-order relations with the perturbative fragmentation function. (HEP, Cavendish Laboratory, University of Cambridge, 2005-01)I present new results on the quark distribution in an on-shell heavy quark in perturbative QCD and explore its all–order relations with heavy–quark fragmentation. I first compute the momentum distribution function to all ...
