标题： Magnetic properties of the hadron resonance gas with physical magnetic moments

摘要： 我们研究了强（$0 \le B \le 0.15~{\rm GeV}^2$）均匀磁场存在下强子共振气体的磁性质，使用了强子磁矩的实际值，即包括它们的反常部分。 这些磁矩的数值取自实验，或者在无法获得时从理论估算中得出。 我们评估了守恒荷涨落，发现了反常磁矩预期的巨大效应，特别是对于八重态重子，如质子和中子，其中这些效应异常显著。 我们还详细研究了$\Delta(1232)$态的磁矩所产生的巨大效应，对于这些态，各种理论估计和实验值之间存在显著差异。 我们将模型结果与格点QCD数据进行了比较，并在模型不确定性范围内找到了合理的吻合。 显示英文摘要

摘要： We study magnetic properties of the Hadron Resonance Gas in the presence of a strong ($0 \le B \le 0.15~{\rm GeV}^2$) uniform magnetic field, using physical values of the magnetic moments of hadrons, i.e., including their anomalous parts. The values of these moments are taken from experiment, or when unavailable, from theoretical estimates. We evaluate the conserved charge susceptibilities, finding the expected sizable effects of the anomalous magnetic moments, in particular of the octet baryons, such as the proton and neutron, where they are exceptionally large. We also study in detail the large effects of the magnetic moments of the $\Delta(1232)$ states, for which various theoretical estimates and experimental values differ significantly. We compare our model results with the lattice QCD data and find reasonable agreement within the model uncertainty.
