论文摘要
重型离子碰撞中产生的夸克gluon等离子体具有三个相关的保守指控：巴里昂数字（b），陌生（S）和电荷（q）。在这里，我们为BSQ扩散的以色列-Stewart框架得出了与剪切和散装粘度耦合以及将其搭配到状态BSQ方程所需的热力学衍生物。我们在DNMR方法中重现了$ {\ Mathcal {J}} $项的子集，并提出了一种从最大熵原理中得出其他术语的技术。最后，我们进行了稳定分析，可用于限制BSQ流体动力学中的运输系数。
The Quark Gluon Plasma produced in heavy-ion collisions has three relevant conserved charges: baryon number (B), strangeness (S), and electric charge (Q). Here we derive the Israel-Stewart framework for BSQ diffusion coupled to shear and bulk viscosity and the thermodynamic derivatives needed to couple this to a BSQ equation of state. We reproduce a subset of the ${\mathcal{J}}$ terms in the DNMR approach and propose a technique to derive other terms from the maximum entropy principle. Finally, we preform a stability analysis that can be used to constraint transport coefficients in BSQ hydrodynamics.
