Abstract

The net-baryon number is essentially transported by valence quarks that probe the saturation regime in the target by multiple scattering. The net baryon distributions, nuclear stopping power and gluon saturation features in the SPS and RHIC energy regions are investigated by taking advantage of the gluon saturation model with geometric scaling. Predications are made for the net-baryon rapidity distributions, mean rapidity loss and gluon saturation features in central Pb + Pb collisions at LHC.
- quark gluon plasma,
- net baryon distribution,
- gluon saturation
