| Popis: | Charm production by gluons and light quarks not in chemical equilibrium (the hot-glue scenario) is explored in a one-dimensional Bjorken-type expansion. The quark-gluon plasma background evolves according to chemical kinetic equations that include gluon fragmentation and light quark production. The momentum distributions of all particles are assumed to be Bose/Fermi. The parameter space is constrained through the initial energy density and the final state entropy. It is found that initial hard processes contribute far more to the final state charm abundance than in plasma production. |
