具有多重性的喷流动量剖面的标度性质

Scaling properties of jet-momentum profiles with multiplicity

Antal Gemes, Robert Vertesi, Gabor Papp, Gergely Gabor Barnafoldi

摘要:

利用\textsc{Pythia} 8蒙特卡罗模拟研究了LHC能区质子-质子碰撞中喷流的结构。我们证明了径向喷流剖面在很宽的横动量范围内表现出与带电强子事件多重性的标度特性。我们还提供了参数化的射流配置文件的基础上不同的激励分析分布。在此基础上,我们提出的标度行为源于射流破碎的基本统计特性。

英文摘要:

We study the structure of jets in proton-proton collisions at LHC energies using \textsc{Pythia} 8 Monte Carlo simulations. We demonstrate that the radial jet profiles exhibit scaling properties with charged-hadron event multiplicity over a broad transverse-momentum range. We also provide parametrizations of the jet profiles based on different statistically-motivated analytical distributions. Based on this we propose that the scaling behavior stems from fundamental statistical properties of jet fragmentation.
