Using QCD methods we re-evaluate strangeness and charm production in a thermal QGP fireball. QCD renormalization group is employed to evaluate running of the parameters αs(μ) and ms(μ). We resum even-αs Feynman diagrams involving two particles in initial and final states. We obtain thermal relaxation times in a simple dynamical description of the fireball and we use these results to study two generic strangeness observables as function of collision energy: specific (per baryon) strangeness yield (s̄)/B, and phase space occupancy γs. From these two quantities, knowing the hadronization process in rough detail, we obtain the final state strange particle abundances.
