LHC pp碰撞多重数分布的三分量描述

A three-component description of multiplicity distributions in pp collisions at the LHC

I. Zborovský

摘要:

本文研究了TeV能量强子相互作用中多粒子产生的全局特征中出现的新现象的一个可能信号。在三个负二项分布函数加权叠加的唯象框架下,分析了在欧洲核子研究中心(CERN)大型强子对撞机上测量的质子-质子碰撞带电粒子多重数分布。实验数据的检查表明,在低的多重性,可以描述为一个单独的组件在总分布中的窄峰的存在。第三分量的多重数特性揭示了近似的能量和赝快度不变性,其物理解释是高能多粒子产生中一个具有挑战性的问题。

英文摘要:

A possible signal of new phenomena emerging in the global characteristics of multiparticle production in hadron interactions at TeV energies is studied. The multiplicity distributions of charged particles measured in proton-proton collisions at the Large Hadron Collider at CERN are analyzed in the phenomenological framework of the weighted superposition of three negative binomial distribution functions. The examination of the experimental data indicates the existence of a narrow peak at low multiplicities which can be described by a separate component in the total distribution. The multiplicity characteristics of the third component reveal approximate energy and pseudorapidity invariance, of which a physical explanation represents a challenging problem in high energy multiple particle production.
