运行着所有的高能核碰撞

Running the gamut of high energy nuclear collisions

Bjoern Schenke, Chun Shen, Prithwish Tribedy

摘要:

我们提出了大量的各种各样的碰撞系统中的混合形式主义,包括IP的初始条件,MUSIC粘性相对论流体动力学,UrQMD微观强子输运的体积属性和多粒子相关性的计算。特别地,我们研究了大型强子对撞机(LHC)上的重离子碰撞,包括Pb+Pb、Pb + Ru和O+O碰撞,以及相对论重离子对撞机(RHIC)上的Au+Au、U+U、Ru+Ru、Zr+Zr和O+O碰撞。我们进一步研究了非对称系统,包括p+Au,d+Au,$^3$ He+Au,和p+Pb碰撞在各种能量以及p+p碰撞在0.5和13 TeV。我们用一组固定的参数很好地描述了所有重离子系统中的实验观测值,验证了框架的能量和系统依赖性。在较小的系统中的许多可观测量也得到了很好的描述,尽管它们测试了模型的极限。O+O碰撞的计算为RHIC和LHC未来可能的运行提供了预测。

英文摘要:

We present calculations of bulk properties and multiparticle correlations in a large variety of collision systems within a hybrid formalism consisting of IP-Glasma initial conditions, MUSIC viscous relativistic hydrodynamics, and UrQMD microscopic hadronic transport. In particular, we study heavy ion collisions at the Large Hadron Collider (LHC), including Pb+Pb, Xe+Xe, and O+O collisions, and Au+Au, U+U, Ru+Ru, Zr+Zr, and O+O collisions at the Relativistic Heavy Ion Collider (RHIC). We further study asymmetric systems, including p+Au, d+Au, $^3$He+Au, and p+Pb collisions at various energies as well as p+p collisions at 0.5 and 13 TeV. We describe experimental observables in all heavy ion systems well with one fixed set of parameters, validating the energy and system dependence of the framework. Many observables in the smaller systems are also well described, although they test the limits of the model. Calculations of O+O collisions provide predictions for potential future runs at RHIC and LHC.
