Charged pion production in heavy ion collisions at √Snn =17.3 Gev. Comparison with models
Abstract
We present nuclear modification factor as a function of transverse momentum for charged pions, produced in peripheral collisions of lead ions at √Snn =17.3 GeV. Results are presented for positive pions, negative pions and average pion production. Experimental results are compared to models UrQMD2.3, EPOS1.67 and HIJING1.7. Comparative study allow us to conclude that simulation of charged pion production within EPOS1.67 has better agreement with experimental data for this type of collision.
