Description

The hadron/pion ratio is calculated in 200 GeV AuAu collisions at midrapidity, applying pQCD and non-universal transverse-momentum broadening. Arguments are presented for such non-universality, and the idea is implemented in a model, which reproduces the main features of the centrality dependence of the hadron/pion ratio in AuAu collisions. The model also reasonably describes the qualitative difference between the recently measured dAu nuclear enhancement factors for pions and charged hadrons. (letter to the editor)
