e+e碰撞多重数的修正Tsallis和Weibull分布

Modified Tsallis and Weibull distributions for multiplicities in e+e- collisions

S. Sharma, M. Kaur, S. Thakur

摘要:

利用Tsallis q统计量和最近提出的Weibull分布函数,在限制快度窗口和全相空间中研究了能量范围为14 ~ 91 GeV的e^{+}e^{-}碰撞中产生的带电粒子的多重数分布.结果表明,Tsallis $q$统计量在所有快度范围内都能很好地解释数据,而威布尔分布在全相空间内不能再现数据。修改的分布,提出建立多方面的改进,在拟合的数据。

英文摘要:

Multiplicity distributions of charged particles produced in the e^{+}e^{-} collisions at energies ranging from 14 to 91 GeV are studied using Tsallis q-statistics and the recently proposed Weibull distribution functions, in both restricted rapidity windows as well as in full phase space. It is shown that Tsallis $q$-statistics explains the data excellently in all rapidity ranges while the Weibull distribution fails to reproduce the data in full phase space. Modifications to the distributions are proposed to establish manifold improvements in the fitting of the data.
