Abstract: We argue that the collinear factorization of the fragmentation functions inhigh energy nuclear collisions breaks down at transverse momenta $p T \lesssimQ s-g$ due to high parton densities in the colliding hadrons and-or nuclei. Wefind that gluon recombination dominates in that $p T$ region. We calculate theinclusive cross-section for $\pi$ meson and nucleon production using the lowenergy theorems for the scale anomaly in QCD, and compare our quantitativebaryon-to-meson ratio to the RHIC data.
