Event-by-event hydrodynamic evolution for 20Ne+20Ne @ 5.36 TeV from IP-Glasma + JIMWLK + MUSIC + UrQMD framework

This repository contains event-by-event hydrodynamic evolution for 20Ne+20Ne collisions at 5.36 TeV. The numerical simulations are performed using the IP-Glasma + JIMWLK + MUSIC + UrQMD framework. Boost invariance is assumed in the longitudinal direction. The simulations are generated with the iEBE-MUSIC framework (#d7e86df).

The medium evolution profiles for individual collision events are stored in the “CXX-YY.tar.gz” files. Centrality bin was defined using the multiplicity of final-state charged hadrons at mid-rapidity. The hydrodynamic evolution files are called “evolution_all_xyeta.dat”. The positions of initial binary collisions are stored in the file “NcollList_XYZ.dat”, where XYZ is the global event ID in the simulations. Charged hadron and identified particle multiplicities and mean pT are recorded in the “particle_yield_and_meanpT_XYZ.dat” file. The anisotropic flow vectors of all charged hadrons are stored in “Qn_vectors_XYZ.dat”. The default pT cut is 0.2 to 3.0 GeV. The "observables.tar.gz" file contains a selection of experimental observables analyzed from the simulations.

The hydrodynamic evolution can be read by a program, https://github.com/chunshen1987/hydro_analysis. This program can provide all the dynamic information at any given space-time position. Please set “hydro_type” to 31 to properly read in the (2+1)D hydrodynamic medium.
