1105.1835 (Shuang LI et al.)

Gluon saturation and baryon stopping in the SPS, RHIC and LHC energy
regions
   [PDF]

Shuang LI, Sheng-Qin Feng
A new geometrical scaling method with gluon saturation rapidity limit is
proposed to study the gluon saturation feature of the central rapidity region
of relativistic nuclear collisions. The net-baryon number is essentially
transported by valence quarks that probe the saturation regime in the target by
multiple scattering. We take advantage of the gluon saturation model with
geometric scaling of the rapidity limit to investigate the net baryon
distributions, nuclear stopping power and gluon saturation features in the SPS
and RHIC energy regions. Predictions for net-baryon rapidity distributions, the
mean rapidity loss and gluon saturation feature in central Pb + Pb collisions
at LHC are made in this paper.
