Predictions for net-proton and net-kaon distributions at LHC energies

TL;DR

This paper models baryon and charge transport in heavy-ion collisions, compares with RHIC data, and predicts net-proton and net-kaon distributions at LHC energies using the gluon saturation model.

Contribution

It provides new predictions for net-proton and net-kaon rapidity distributions at LHC energies based on the gluon saturation model.

Findings

Net-proton distributions at LHC energies are predicted for various collision energies.

Net-kaon distributions are calculated and compared with RHIC data.

The model emphasizes the midrapidity valley in rapidity distributions.

Abstract

We investigate baryon and charge transport in relativistic heavy-ion collisions, compare with Au + Au RHIC data at sqrt(s_NN)=0.2 TeV, and make predictions for net-proton rapidity distributions in central Pb + Pb collisions at CERN LHC energies of sqrt(s_NN)=2.8, 3.9, and 5.5 TeV. We use the gluon saturation model and put special emphasis on the midrapidity valley |y|< 2. Net-kaon distributions are calculated and compared to BRAHMS Au + Au data at RHIC energies of sqrt(s_NN)= 0.2 TeV, and predicted for Pb + Pb at 5.5 TeV.
