论文摘要
使用具有示意性初始条件的非线性扩散方程的分析溶液以及具有奇异性边界条件的胶状的非线性扩散方程的分析溶液,对相对论重离子碰撞的初始阶段的夸克和胶结的快速热化进行了处理。在$ t \ le1 $ fm/$ c $的类似短时间里,基于价值夸克和gluons的parton分布功能,通过QCD启发的方法来解释Baryons的停止。使用两个碎片源的线性相对论扩散模型和一个以$ \ ln^3(s_ {nn})$上升的中央gluonic源,从而在现象学上产生了带电的 - 哈德隆的产生。发现在相对论重离子撞机(RHIC)达到的能量数据的限制性裂缝猜想与$ \ sqrt {s_ {nn}}} = 2.76美元和$ 5.02 $ $ 5.02 $ tev的PB-PB的大型强子撞机(LHC)数据一致。 Quarkonia通过比较理论预测与最近的CMS,Alice和LHCB数据的PB-PB和P-PB碰撞来比较Quarkonia用作夸克 - 胶质等离子体(QGP)性质的硬探针。
The rapid thermalization of quarks and gluons in the initial stages of relativistic heavy-ion collisions is treated using analytic solutions of a nonlinear diffusion equation with schematic initial conditions, and for gluons with boundary conditions at the singularity. On a similarly short time scale of $t \le1$ fm/$c$, the stopping of baryons is accounted for through a QCD-inspired approach based on the parton distribution functions of valence quarks, and gluons. Charged-hadron production is considered phenomenologically using a linear relativistic diffusion model with two fragmentation sources, and a central gluonic source that rises with $\ln^3(s_{NN})$. The limiting-fragmentation conjecture that agrees with data at energies reached at the Relativistic Heavy Ion Collider (RHIC) is found to be consistent with Large Hadron Collider (LHC) data for Pb-Pb at $\sqrt{s_{NN}}= 2.76$ and $5.02$ TeV. Quarkonia are used as hard probes for the properties of the quark-gluon plasma (QGP) through a comparison of theoretical predictions with recent CMS, ALICE and LHCb data for Pb-Pb and p-Pb collisions.
