Insights into nuclear coalescence during freeze-out.

Comparison of NMF definitions and their implications.

Abstract

We have studied the behaviour of the nuclear modification factor as a function of centrality, chemical baryon potential and thermal freeze out temperature using the data coming from the Fast Hadron Freezeout Generator. Considering two ways of NMF definition, namely the ratio of meson yields and ratio of baryons yield, we considered two associates effects (for percolation cluster formation) to identify it; appearance of the anomalous nuclear transparency and light nuclei production. In this paper we have used the behaviour of nuclear modification factor as a function of different physical parameters to get the information of the behavior of nuclear transparency effect and the nuclear coalescence in freezeout state. We have chosen different generators for this purpose. Here we have used the simulated data for Au-Au collisions at RHIC energies coming from the FASTMC Model. This model is very good in freezeout state.
