Abstract:
The ratio of particle to antiparticle yields is of great importance to determine the freeze-out parameters, but, also, to eliminate the volume fluctuations. Some simulation results obtained with the code AMPT-v1 26t7 and the code UrQMD 3.3 are compared with those using other simulation codes, as SHARE, AMPT-v1.21-v2.21.
We present some interesting repetitive phenomena seen with both generators AMPT and UrQMD (e.g. in the 18-20 A GeV energy interval, for the second centrality class, in rapidity range 0
