Estimation of the freeze-out parameters reachable in a fixed-target experiment at the CERN Large Hadron Collider

Estimation of the freeze-out parameters as a function of the rapidity in Pb + Pb collisions at root S-NN = 72 GeV in the AFTER@LHC project is performed. The conventional hadron resonance gas model is used for analysis of the events generated by the UrQMD model. The results indicate that one may obtain at least a 2.5 times increase in the baryon chemical potential mu(B) in the forward rapidity range compared to the midrapidity range. The mu(B) values in the rapidity range of 0 < y < 4.5 for AFTER@LHC are comparable to those covered by the RHIC Beam Energy Scan program. Thus, a rapidity scan in the AFTER@LHC project provides a complementary approach for study of the QCD phase diagram.
