论文摘要
我们部署了一个动力学速率方程式，以评估$ J/ψ$，$ψ（2s）$，$ b_c $和X（3872）的运输，以在超占领的重型离子碰撞中进行比较，并将其生产收益率与大型Hadron Collider的实验数据进行比较。速率方程有两个主要的传输参数，即每个状态的平衡极限和反应速率。与温度有关的平衡极限包括魅力和底价的fugacities，其初始产生。 Charmonia，Bottomonia和$ b_c $的反应率依赖于魅力和底部夸克群体以及来自热力学$ t $ -matrix方法的结合能。对于X（3872）粒子，其内部结构信息通过两种不同的情况在辐射相的反应速率和初始条件中编码：一种松散结合的Hadroonic分子与紧凑型diquark-andidiquark Tetraquark。
We deploy a kinetic-rate equation to evaluate the transport of $J/ψ$, $ψ(2S)$, $B_c$ and X(3872) in ultra-relativistic heavy-ion collisions and compare their production yields to experimental data from the Large Hadron Collider. The rate equation has two main transport parameters, i.e., the equilibrium limit and reaction rate for each state. The temperature-dependent equilibrium limits include charm- and bottom-quark fugacities based on their initial production. The reaction rates for charmonia, bottomonia and $B_c$ rely on charm- and bottom-quark masses as well as binding energies from a thermodynamic $T$-matrix approach. For the X(3872) particle, its internal structure information is encoded in reaction rates and initial conditions in the hadronic phase via two different scenarios: a loosely bound hadronic molecule vs. a compact diquark-antidiquark tetraquark.
