摘要:

用EPOS 3模型和UrQMD描述强子相,研究了$\sqrt{s_{NN}}$ = 5.02 TeV的p-Pb碰撞中短寿命强子共振的产生及其产额和$p_{T}$谱的修正.高多重数的p-Pb碰撞表现出类似的行为,在LHC能量的中间-外围的Pb-Pb碰撞,我们发现在p-Pb碰撞,可以通过散射过程修改共振产额和$p_{T}$光谱的一个短暂的强子阶段的迹象。为了研究p-Pb碰撞中集体效应的发生,研究了共振产生随系统尺寸的演化,系统尺寸与强子相的寿命有关.我们还研究强子生产分别在这些碰撞的核心和日冕部分,并探讨这种分工如何影响总粒子产量的系统尺寸的增加。

英文摘要:

Using the EPOS3 model with UrQMD to describe the hadronic phase, we study the production of short-lived hadronic resonances and the modification of their yields and $p_{T}$ spectra in p-Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV. High-multiplicity p-Pb collisions exhibit similar behavior to mid-peripheral Pb-Pb collisions at LHC energies, and we find indications of a short-lived hadronic phase in p-Pb collisions that can modify resonance yields and $p_{T}$ spectra through scattering processes. The evolution of resonance production is investigated as a function of the system size, which is related to the lifetime of the hadronic phase, in order to study the onset of collective effects in p-Pb collisions. We also study hadron production separately in the core and corona parts of these collisions, and explore how this division affects the total particle yields as the system size increases.
