The transverse momentum distribution of identified hadrons from recent years are analyzed within the thermodynamically consistent formulation of non-extensive statistics. A wide range of center-of-mass energies and average event multiplicities are studied for various hadron species. We demonstrate that the average event multiplicity is a key variable in the study of high-energy collisions and a smooth transition in the description from small to large systems is possible. For this purpose the non-extensive statistical approach is more than appropriate. The validity of the non-extensive description is explored in multiple ways: such as the calculation of integrated yields per unit rapidity, the analysis of radial flow and the consistency check of the thermodynamical variables. The ‘Tsallis-thermometer’ is introduced as an indicator of quark-gluon plasma in small collisional systems.

Tsallis温度计:用于大型和小型碰撞系统的QGP指示器

在非广泛统计的热力学一致公式中,分析了近年来发现的强子的横向动量分布。研究了各种强子种类的广泛的质心能量和平均事件多重性。我们证明,平均事件多重性是高能碰撞研究中的关键变量,描述中从小型系统到大型系统的平稳过渡是可能的。为此目的,非广泛的统计方法是适当的。非广泛描述的有效性通过多种方式进行探讨:例如计算单位快速度的综合产量,径向流分析和热力学变量的一致性检查。
