论文摘要
我们介绍了在多相传输（AMPT）模型中生产奇怪的重生的其他合并因素，以描述在PB-PB碰撞中观察到的多分机Hadron的增强的生产。 \ sqrt {s_ {nn}} $ = 200 GEV在相对论重型离子对撞机（RHIC）中。该扩展的AMPT模型还可以合理描述$ \ rm \ rm \ rm \ rm \ rm \ sp $ pp $ pp $ collixions $ \ rm \ sp pp $ pp $ pp $ pp $ pp $ pp $ pp $ pp $ pp $ flixption in pp $ pp $ pp $ flixption collixions $ \ rm \ s的多样性依赖性的多样性依赖性。 $ \ rm \ sqrt {s_ {nn}} $ = 5.02 tev。我们发现合并因子取决于系统的大小，但并不是对系统是否是由A+A或P+A碰撞产生的。因此，扩展的AMPT模型提供了一种方便的方法，可以对RHIC和LHC能量的小型和大型系统的碰撞中观察到的陌生性增强的基础机制进行建模。
We introduce additional coalescence factors for the production of strange baryons in a multiphase transport (AMPT) model in order to describe the enhanced production of multistrange hadrons observed in Pb-Pb collisions at $\rm \sqrt{s_{NN}}$ = 2.76 TeV at the Large hadron Collider (LHC) and Au+Au collisions at $\rm \sqrt{s_{NN}}$ = 200 GeV at Relativistic Heavy-Ion Collider (RHIC).This extended AMPT model is found to also give a reasonable description of the multiplicity dependence of the strangeness enhancement observed in high multiplicity events in $pp$ collisions at $\rm \sqrt{s}$ = 7 TeV and $p$-Pb collisions at $\rm \sqrt{s_{NN}}$ = 5.02 TeV. We find that the coalescence factors depend on the system size but not much on whether the system is produced from A+A or p+A collisions. The extended AMPT model thus provides a convenient way to model the mechanism underlying the observed strangeness enhancement in collisions of both small and large systems at RHIC and LHC energies.
