在这篇贡献中，我们从虚化学势的晶格模拟中恢复了量子色动力学（QCD）的状态方程。我们将以前的工作[1]中介绍的格式推广到非零奇异化学势的情况。在130MeV≤T≤280 MeV的温度范围内，化学势达到μB/T= 3:5，沿着奇异中性线，给出了连续统外推结果。此外，通过外推奇异度与重子数之比=nS/nB的小值，我们放宽了奇异度中性的约束。
In this contribution we present a resummation of the Quantum Chromodynamics (QCD) equation of state from lattice simulations at imaginary chemical potentials. We generalize the scheme introduced in a previous work [1], to the case of non-zero strangeness chemical potential. We present continuum extrapolated results for thermodynamic observables in the temperature range 130MeV ≤T≤ 280 MeV, for chemical potentials up to μB/T= 3:5, along the strangeness neutral line. Furthermore, we relax the constraint of strangeness neutrality, by extrapolating to small values of the strangeness-to-baryon-number ratioR=nS/nB.
