Composite particle formation in Au plus Au reactions at 11.6A GeV/c: Towards a new approach

We deal with some of the main characteristics of proton and deuteron production in Au + Au reactions at 11.6A GeV/c with the help of a new approach. From the viewpoint of the combination of two models and an important phenomenological parametrization, we analyze both laboratory data and the model-constructs from which we finally summarize two crucial features: (i) nucleon-nucleon and nucleus-nucleus collisions could be treated on a unified footing; (ii) production of hadrons like pions, protons etc. and deuterons as well, could be studied in a somewhat similar way. Besides, it is also shown that the totality of the approach outlined and utilized here is quite capable of obtaining the physical projections based on the popular relativistic quantum molecular dynamic (RQMD) model, and can also accommodate some actual measurements already made in the past.
