摘要

利用具有排斥性平均场的强子共振气体模型研究了QCD态方程、重子数和奇异度的涨落。我们发现，在共振气体模型中同时包含预测但未观测到的共振，即缺失态和排斥平均场，可以更好地描述晶格结果。排斥平均场对高阶重子数涨落尤为重要。

Hadron gas with repulsive mean field

We study the QCD equation of state, and fluctuations of baryon number and strangeness using the hadron resonance gas model with repulsive mean field. We find that including both the predicted but not observed resonances, a.k.a. missing states, and the repulsive mean field into the resonance gas model leads to better description of the lattice results. The repulsive mean field is particularly important for the higher order baryon number fluctuations.
