Title: 质子多重性在临界点附近的阶乘累积量使用最大熵冻结输出方案

Abstract: We present the first application of the maximum-entropy freeze-out prescription to calculate factorial cumulants of proton multiplicities near the conjectured QCD critical point in thermal equilibrium. We map the Gibbs free energy of the 3D Ising model to a parameterized class of possible EoS near QCD critical point. This equilibrium baseline highlights how factorial cumulants isolate critical fluctuations by subtracting trivial self-correlations, setting the stage for future out-of-equilibrium analyses. We identify the key non-universal aspects of the mapping to the Ising model that strongly control the characteristic properties, such as magnitude and location of the peaks of the factorial cumulants along the freeze-out curve.

Abstract: 我们首次应用最大熵冻结方案来计算接近假设的QCD临界点的质子多重性因子累积量，在热平衡中。 我们将3D伊辛模型的吉布斯自由能映射到QCD临界点附近可能的EoS参数类。 这种热平衡基线突显了因子累积量如何通过减去平凡的自相关来分离临界涨落，为未来的非平衡分析奠定了基础。 我们确定了映射到伊辛模型的关键非普遍方面，这些方面强烈控制着因子累积量的特征属性，例如沿冻结曲线的峰值大小和位置。
