论文摘要
我们在零温度下以近代的降级顺序有同胞素化学势，计算三种味性手性扰动理论（$χ$ pt）中的光夸克冷凝物，奇怪的夸克冷凝物，斜向冷凝物和轴向冷凝物。结果表明，可以通过将具有奇怪的夸克含量（Kaons and ETA）的介子组合在一起，并将三种味道$χ$ PT有效潜力和冷凝物映射到两种味道$χ$ PT上。我们比较了有限伪源的光夸克和式pion冷凝物与（$ 2+1 $） - 风味晶格QCD的结果，我们还比较了零伪和轴向源的轴向冷凝物和轴向源的轴向冷凝物和轴向源。我们发现，光夸克，亲和轴向冷凝水与晶格数据非常吻合。通过包括NLO效应，总体上有所改善。
We calculate the light quark condensate, the strange quark condensate, the pion condensate, and the axial condensate in three-flavor chiral perturbation theory ($χ$PT) in the presence of an isospin chemical potential at next-to-leading order at zero temperature. It is shown that the three-flavor $χ$PT effective potential and condensates can be mapped onto two-flavor $χ$PT ones by integrating out mesons with strange quark content (kaons and eta), with renormalized couplings. We compare the results for the light quark and pion condensates at finite pseudoscalar source with ($2+1$)-flavor lattice QCD, and we also compare the axial condensate at zero pseudoscalar and axial sources with lattice QCD data. We find that the light quark, pion, and axial condensates are in very good agreement with lattice data. There is an overall improvement by including NLO effects.
