Abstract
We argue that the collinear factorization of the fragmentation functions in high energy nuclear collisions breaks down at transverse momenta due to high parton densities in the colliding hadrons and/or nuclei. We find that gluon recombination dominates in that region. We calculate the inclusive cross-section for meson and nucleon production using the low energy theorems for the scale anomaly in QCD, and compare our quantitative baryon-to-meson ratio to the RHIC data.
