The mid-rapidity transverse-momentum spectra of charmed meson in Pb-Pb and pp($\overline{\text{p}}$) collisions are analyzed by Tsallis-Pareto distribution derived from non-extensive statistics. We perform uniform descriptions for both small large systems over a wide range collision energy hadron transverse momentum. By establishing the relation between event multiplicity Tsallis parameters, we...

We describe in detail two numerical simulation methods valid to study systems whose thermostatistics is described by generalized entropies, such as Tsallis. The methods are useful for applications to non-trivial interacting systems with a large number of degrees of freedom, and both short–range and long–range interactions. The first method is quite general and it is based on the numerical evalu...
