Abstract

Recently, data from the collaborations CMS, ATLAS, ALICE, and PHENIX indicated signals of collectivity in the small collision systems created in RHIC and LHC.In this project, we plan to investigate and compare the properties of these systems using both hydrodynamical and transport models.The hydrodynamic approach implies the hypothesis that the system reaches the thermodynamic equilibrium, while the transport model is free of such conjecture.It is therefore interesting to carry out a systematic study and compare the two different models regarding the thermodynamic quantities of a system in local equilibrium, such as temperature, entropy, in addition to empirical quantities such as particle spectra, collective flows and particle correlations.And we also intend to look into the possibility of analyzing the properties of the granularity as well as the collectivity of such systems in terms of the tube model.Besides, we propose to continue studying the precision, stability, and efficiency of the smoothed particle hydrodynamics algorithm and its implementation using SPheRIO code.
