摘要:

利用Tsallis分布作为参数化,研究了横向动量分布随束流能量的变化。Tsallis参数q,T和体积的依赖性被确定为光束能量的函数。Tsallis参数q示出了随着束能量的微弱但明显的增加,最高值约为1.15。的Tsallis温度和体积是一致的,在实验的不确定性与束能量无关。

英文摘要:

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 are determined as a function of beam energy. 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.
