Description

This repository contains Thermal-FIST routines for calculations within the Canonical Statistical Model (CSM) presented in the following papers:

• V. Vovchenko, B. Dönigus, H. Stoecker, Multiplicity dependence of light nuclei production at LHC energies in the canonical statistical model, Phys. Lett. B 785, 171 (2018) [arXiv:1808.05245 [hep-ph]]
• V. Vovchenko, B. Dönigus, H. Stoecker, Canonical statistical model analysis of p-p, p-Pb, and Pb-Pb collisions at the LHC, Phys. Rev. C 100, 054906 (2019) [arXiv:1906.03145 [hep-ph]]

The calculations are done within interactive Jupyter sessions. This is achieved through the xeus-cling Jupyter kernel and a C++ interpreter cling.

The routines presented here have so far only been tested on a Linux system.

Pre-requisites

A Python environment with Jupyter Notebook and xeus-cling installed.

Usage

1. Close this repository with the --recurse-submodules option to fetch the Thermal-FIST package automatically.
2. Build Thermal-FIST and Minuit2 as shared libraries. One can execute the `build.sh' script in the root directory, or run the following commands manually:

   cd Thermal-FIST
   mkdir build
   cd build
   cmake -DBUILD_SHARED_LIBS=ON -DSTANDALONE_MINUIT=ON ../
   make ThermalFIST

   This will build the shared libraries in folder Thermal-FIST/build/lib.
3. Run jupyter notebook from the repository root directory, open it in a browser and go to the index.ipynb notebook. This notebook contains links to all the routines for obtaining the results published in the above papers. The output files will be written into the folder out/.

The reference output files are available in folders out/reference.1808.05245 and out/reference.1906.03145
