Thermal-FIST

Thermal-FIST (or simply The FIST) is a C++ package designed for the convenient general-purpose analysis within the family of the hadron resonance gas (HRG) models. This mainly includes the statistical analysis of particle production in heavy-ion collisions and the phenomenology of the hadronic equation of state.

Particular emphasis is put on fluctuations and correlations of conserved charges, effects of probabilistic decay, chemical non-equilibrium, and inclusion of hadronic interactions.

Calculations are possible within the grand canonical ensemble, the canonical ensemble, as well as in mixed-canonical ensembles combining canonical treatment of strangeness/charm with the grand-canonical treatment of other conserved numbers.

The package contains a fast thermal event generator, with Blast Wave model based momentum distributions, and possibility of simultaneous inclusion of effects of exact charge conservation and hadronic interactions.

The package also includes QtThermalFIST -- a Qt-based graphical user interface designed for a fast and convenient general-purpose thermal model analysis.

Notes on the present version

The package is not fully documented yet, but should be perfectly usable. See the Quick Start Guide

Note that calculations may break down for excessive/overstressed parameters. This should be carefully monitored.
