威布尔分布与$pp\,(p\bar{p})$碰撞的多重矩

Weibull Distribution and the multiplicity moments in $pp\,(p\bar{p})$ collisions

Ashutosh Kumar Pandey, Priyanka Sett, Sadhana Dash

摘要:

本文用Weibull描述的SPS和LHC能区$pp\,(p\bar{p})$碰撞中的粒子产生,对多重数分布进行了高阶矩分析。将威布尔分布的归一化矩和阶乘矩与实测数据进行了比较。计算的Weibull矩被发现是在良好的协议与测得的较高的时刻(高达5 $^{\rm{th}}$顺序)再现所观察到的打破KNO标度的数据。预测了$\sqrt{s}$ = 13 TeV时$pp$碰撞的矩。

英文摘要:

A higher moment analysis of multiplicity distribution is performed using the Weibull description of particle production in $pp\,(p\bar{p})$ collisions at SPS and LHC energies. The calculated normalized moments and factorial moments of Weibull distribution are compared to the measured data. The calculated Weibull moments are found to be in good agreement with the measured higher moments (up to 5$^{\rm{th}}$ order) reproducing the observed breaking of KNO scaling in the data. The moments for $pp$ collisions at $\sqrt{s}$ = 13 TeV are also predicted.
