Abstract
Heavy long-lived quarks, i.e. charm and bottom, are frequently
studied both as tests of QCD and as probes for other physics
aspects within and beyond the standard model. The long lifetime
implies that charm and bottom hadrons are formed and observed.
This hadronization process cannot be studied in isolation, but
depends on the production environment. Within the framework of
the string model, a major effect is the drag from the other end
of the string that the c/b quark belongs to. In extreme cases,
a small-mass string can collapse to a single hadron, thereby
giving a non-universal flavor composition to the produced hadrons.
We here develop and present a detailed model for the charm/bottom
hadronization process, involving the various aspects of string
fragmentation and collapse, and put it in the context of several
heavy-flavor production sources. Applications are presented
from
fixed-target to LHC energies.
