Baryon stopping and Feynman scaling in the color glass condensate approach

In this work baryon stopping and leading baryon production are investigated in the context of the color glass condensate (CGC) formalism.

Description
Summary:In this work baryon stopping and leading baryon production are investigated in the context of the color glass condensate (CGC) formalism. We assume that at large energies the coherence of the projectile quarks is lost and that the leading baryon production mechanism changes from recombination to independent fragmentation. The phenomenological implications for net-baryon production in pp pA AA collisions are analyzed and predictions for LHC energies are presented. We find that at very high energies the leading baryon xF spectra become nearly energy independent and we reach the approximate Feynman scaling regime.
