Nuclei Production and Two Chemical Freeze-Out Model of High Energy Heavy Ion Collisions

摘要

We discuss on the consequence of a multiple freezeout scenario on the production of light nuclei in heavy ion collisions based on thermal as well as simple coalescence models. We argue that irrespective of the production mechanism, ratios of unlike flavor nuclei show a much better agreement with data at the top STAR energy of {formula} = 200 GeV within such a flavor dependent freezeout scheme compared to the standard scenario of a unified freezeout.
