Systematic Properties of the Tsallis Distribution: Energy Dependence of Parameters
arXiv:1309.7466 · doi:10.1088/1742-6596/509/1/012099
Abstract
Changes in the transverse momentum distributions with beam energy are studied using the Tsallis distribution as a parameterization. The dependence of the Tsallis parameters q, T and the volume on beam energy is determined. The Tsallis parameter q shows a weak but clear increase with beam energy with the highest value being approximately 1.15. The Tsallis temperature and volume are consistent with being independent of beam energy within experimental uncertainties.
