A System Size Analysis of the Fireball Produced in Heavy-Ion Collisions †
Abstract
:1. Introduction
2. Materials and Methods
2.1. Tsallis-3 Statistics
2.2. Femtoscopic Approach
3. Results and Discussion
- The correlation function may deviate from a Gaussian shape due to exponential tails caused by resonance decay contributions [35]. This can lead to an underestimation of the femtoscopic radii.
- In the Tsallis statistics, the particle interactions and collective effects, including rescattering, are modeled phenomenologically by deformation of entropy using the nonextensive entropic parameter q.
