论文摘要
使用了LHC的ATLAS协作的结果，对带电粒子多重性和平均横向动量分布的比较。这些分布在质子 - 质子碰撞中的质量中心能量从0.9到13 teV的绝对伪tev型区域小于2.5，并且每个带电的粒子横向动量分别大于100和500 MEV，并且两个事件样本。根据KNO缩放变量，研究了具有碰撞能量的多样性分布的形状演化。 KNO量表上带电的粒子多重性分布具有相似的形状，并且随着碰撞能量的增加而降低。对于最高能量，KNO分布往往与能量无关。 KNO量表上的平均横向动量分布具有相似的形状，并且随着碰撞能量的增加而增加。
The comparisons of the charged-particle multiplicity and the average transverse momentum distributions on the scaled multiplicity, KNO scale, using the results of the ATLAS collaboration at the LHC are presented. These distributions were measured in proton-proton collisions at centre-of-mass energies from 0.9 to 13 TeV for the absolute pseudorapidity region less than 2.5 and two samples of events with each charged-particle transverse momentum greater than 100 and 500 MeV, respectively. The shape evolution of the multiplicity distributions with a collision energy is studied in terms of KNO scaling variables. The charged-particle multiplicity distributions on the KNO scale have the similar shape and decrease with increasing collision energy. The KNO distributions tend to be independent of energy for the highest energies. The average transverse momentum distributions on the KNO scale have a similar shape and increase with increasing collision energy.
