论文摘要
量子染色体动力学（QCD）是否在有限温度和密度下表现出相变是一个空旷的问题。这对于重离子碰撞和中子恒星合并的流体动力建模很重要。晶格QCD模拟明确地表明，当巴龙化学势为零或小时，从黑龙到夸克和胶子的过渡是跨界。我们将通常与3D ISING模型相关的状态的参数缩放方程与基于从HADRON到夸克和胶子的平滑交叉基于状态的背景方程。与来自相对论重离子对撞机或其他加速器的重离子实验中的梁能量扫描II的实验数据相比，如果存在关键点，则可以确定QCD的临界指数和幅度。
Whether Quantum Chromodynamics (QCD) exhibits a phase transition at finite temperature and density is an open question. It is important for hydrodynamic modeling of heavy ion collisions and neutron star mergers. Lattice QCD simulations have definitively shown that the transition from hadrons to quarks and gluons is a crossover when the baryon chemical potential is zero or small. We combine the parametric scaling equation of state, usually associated with the 3D Ising model, with a background equation of state based on a smooth crossover from hadrons to quarks and gluons. Comparison to experimental data from the Beam Energy Scan II at the Relativistic Heavy Ion Collider or in heavy ion experiments at other accelerators may allow the critical exponents and amplitudes in the scaling equation of state to be determined for QCD if a critical point exists.
